Title: SS Ohio tanker build, Pedestal convoy.
Post by: unbuiltnautilus on November 13, 2010, 01:12:14 PM
Hi people,
My first post on Mayhem. As a member of the Portsmouth Model Boat Display Team I thought our new build would be of interest. A large scale effects model of the Texaco tanker, SS Ohio. This is being built as a simplified model in the style of those great Glynn Guest designs, only its 98" long! Only one piece of plywood cut so far, photos to follow.

Are you going the whole way and modelling it as she came into Malta after the Op Pedestal convoy with a destroyer
tied to each beam to get her safely into harbour - now that would be quite a model.

Hi everyone.
Day two of the build. The model is designed to break into three for transport. It is also designed with a reduced draught ( by almost 4" ) to reduce its all up weight. Thanks to yesterdays helper monkeys for all their help.

When I was at Glasgow maritime university, my tutor was the RN fellah who received the VC for salvaging the Ohio. He was a truly lovely unpretentious charactor, his party trick was to run into the room and leap with both feet onto a desk with his hands out, does not sound much, but the desk was pushed up to a full length glass window on the 10 floor, he would afterwards with a mischievous grin remark that one day he might slip and at 65 years he ought to stop doing it. He was at the time of the Ohio incident C O of a fleet minesweeper, which he put alongside of the tanker and supervised the salvage of it, I might add he was a merchant navy master in the RNVR who was called up for the duration.

I like your thinking, positive control. However, would this be a possible cause of interference to either 40mhz FM or 2.4G radio equipment? One for the experts I feel.
Title: Re: SS Ohio tanker build, Pedestal convoy.
Post by: unbuiltnautilus on November 25, 2010, 05:08:47 PM
Days 3 and 4 of the build. The model is divided into three sections; Stern, containing radio control equipment, motor, batteries, possible sound system etc. Midships, containing the control box for the flashes, bangs and smoke. This section is to be fitted with two marine bilge pumps, to allow the model to ballast down to decks awash in a similar way to the real SS Ohio as she entered the safety of Malta, battle damaged and barely afloat. Bow, at the moment, probably just a water tight bouyancy compartment.
As you can see from the photos, a number of members are getting involved with the build, and our momentum hasn't faded yet!
The model is being built out of 8mm ply and we are trying out the new 'foaming' glues no the joints. The joints are screwed and glued, a neccesity with this expanding glue. The one we are using dries in 30 minutes, but reaches full strength in 24 hours. It takes a lot of sanding down! It is ideal for structural work, but I wouldn't use it to glue down deck fittings as they will end up on top of a little yellow hill!!

Re clagging two destroyers either side.

Assume scale of all three vessels is 1:72 ish, and that beam of destroyer is 6", perhaps two submerged 'outriggers' could be attached to OHIO's hull (one third the way back from bows) and both destroyers could manoeuvre their bows up to them?  Outriggers would need to be swept back to avoid drift-off while underway and destroyers could then push their charge. :-)) All the better if she is ballasted down to "gunwhales awash".  Need to be careful of destroyers raked bows riding up on the outriggers though......  %)

I wanna witness this when it happens!

Good luck!
Title: Re: SS Ohio tanker build, Pedestal convoy.
Post by: unbuiltnautilus on November 26, 2010, 01:51:27 PM
Hi Yarpie,
We are planning some sort of outrigger design, possibly with some sort of connection point under the hulls of the destroyers. I'm not sure how to interpret the swept back bit of your suggestion, but it has me thinking about something hinged back in the flow of the water, that will deploy when the model stops or reverses slowly.
Title: Re: SS Ohio tanker build, Pedestal convoy.
Post by: Yarpie on November 26, 2010, 03:04:48 PM
Hi unbuiltnautilus,

my suggestion of slightly sweeping back the outriggers is primarily to keep the destroyer's bows tight to OHIO's hull. If the outriggers were to extend at 90 degrees to the hull then the "attached" destroyer may veer-off. Once the bows are in "fixed" position then the rudders can do the rest. Presumably this evolution is part of a display so any detachment at the wrong moment may detract from that display.

I have seen some of the displays that you Portsmouth guys put on and they are truly world class.

Good luck on this venture, it's pretty ambitious. The build is coming along fine too. :-))

Any other ideas out there on how to achieve this iconic arrangement?

Post by: Yarpie on November 27, 2010, 10:08:49 AM
Another idea may be a small recessed area with rail on the gunwhales of the tanker. Hooks fitted at the foc'sle break on each destroyer could be fashioned to connect with the rail.  Problem with this is that if the tanker was to inadvertently sink, escorts would go under too! Tears at bedtime!

Where's Barnes Wallis when you need him? %)

Formation driving works best when there are one or less models involved on the water, at a time. :}
The radio involved with the bangs and flashes side of the model is a Planet T5, shown below, slightly modified. Will this invalidate the warranty?!

Build Day 5.
Most of the work today involved the locator 'keyways' bonded to the bulkheads between sections. These aid in the successful location of the three parts of the model ( along with M8 stainless nuts, bolt and washers. ). More Baffles/Deck Supports for the midships section, and the securing of the foredeck and small deck section in front of the bridge. This has 2 rectangular holes cut into it to allow access to the forward bolts that will hold the model together. The foredeck went on slightly crooked, so this is being forced horizontal by 2 timber supports until the Polyurethane glue goes off fully, nobodies perfect!! A 34" Crash Tender is posed for scale in one of the photos., a fellow members latest restoration job, looking very good so far.

Hi,
i am nowhere near as experienced as you, but i ma very interested in your build. i have one question about your idea for attaching the destroyers. its a good idea and the diagram is very self explanatory. but what if you want to reverse? would there be no way of maybe attaching the rod from the destroyer to a servo so it can be pushed up into the bracket, that way you will have far more control? just an idea. i look forward to seeing the result.

Post by: Yarpie on December 13, 2010, 10:44:22 AM
Alan,

this is very much in line with the suggestion of outriggers.  Good principle but (there's always a 'but'....), on model destroyers some owners slide their batteries in through the foc'sle deck aperture. A big stick coming from keel to deck level would tend to get in the way. %)  Notwithstanding, it would be possible to drill a hole in the keel of the destroyer and put a short rod in and make sure it really is secured in position to maintain the watertight integrity.

The idea is sound because it is 'quick release'. As OHIO is designed to sink to her gunwhales, any tendency to over-ballast would perhaps drag her under, causing two fully attached destroyers to go down with her.

I further like the idea as the two 'outriggers' can be designed to be removed from the OHIO's hull when it is on static display.

Also, from experience, there would be no reason for the conjoined vessels to go astern as the only motive power came from the destroyers anyway (propulsion and steering).
Title: Re: SS Ohio tanker build, Pedestal convoy.
Post by: unbuiltnautilus on December 13, 2010, 11:08:21 AM
Thanks for the rapid responses. The reversing issue can be overcome by setting Ohios motor running very slowly astern, once the destroyers are attached. The destroyers would provide forward control, but as they throttle back, Ohio would provide astern control.
The holes through the destroyers issue; as an alternative, the post could be secured through the main deck aft of the funnel. Brought up to deck level, maybe under a removable set of torpedo tubes. Any water passing up through the tube would run off the deck without entering the model.

Hope everyone had a great Christmas,
16th December: Today we filled out the joining bulkheads with filler. The method here involved doping, then waxing one side of the bulkhead. Then slapping filler over the opposite side and slapping the two parts together. Then wind up the M8 bolts while resting the two parts of the hull on a flat surface.
(http://s4.postimage.org/1ahwzi65g/IMG_7061a.jpg) (http://postimage.org/image/1ahwzi65g/)
Then comes the good bit. Once the filler has gone off its time to take the two parts apart. Following winding the nuts to the outer end of the threads, I proceeded to nut them with a hammer... Nothing...and again.....Nothing. Plan B, Place the joint between the two hull parts over the table edge and lean down on it!! Snap!!

(http://s4.postimage.org/1al9pqi78/IMG_7063a.jpg) (http://postimage.org/image/1al9pqi78/)
As you can see, the joints seperated with minimal damage, easy to repair.
Next up , fitting what I would call horizontal chine parts. These will allow  the hull sides to change angle as they are fitted from deck to keel, imparting a bit of shape to the hull sides.

Cheers Mate, much appreciated.
The Pre-planning has proved to be a bit of a problem as 80% of it is in my head, while 20% is from plans ( which have not been out of the roll for two weeks!!). with the help on the build from fellow members, we have caught up with all the pre-planned stages and are now building 'in the dark'. I find myself staring at the model on occasions, not sure what to do next.. thank god for members input :-)).

Back to December 19th a moment...
On the bottom of the model, the plan was to fit two battens 1" x 1/2" down the centre of the model, spaced about 6" apart. To provide stability when resting on the lakeside and to protect the prop and rudder. However John says "Why dont you do it like this??"
'This' entailed moving the batten to the edges of the hull, including the shaped sections fore and aft :o
However, in a moment of immense generosity, he then offered to fit them himself... who am I to argue.

'This' entailed moving the batten to the edges of the hull, including the shaped sections fore and aft :o
However, in a moment of immense generosity, he then offered to fit them himself... who am I to argue.

What then followed could be described as the 'great christmas G-clamp hunt of 2010' , as the parts had been weakened by placing bandsaw cuts into them, it seemed unwise to drill and screw them into position. therefore it was decided to clamp and glue them only, a good test for the PU adhesive..

December 23rd again,
At the stern of the model, members were working on producing a pattern for the plywood hull plating. The intention is to use 8mm thick ply to skin the model. This is a bit heavy for normal use, a more practical hull thickness would be about 3mm, which would bend around awkward curves easier, however, this needs to be literally 'bomb proof'!

(http://s4.postimage.org/28b17uxlw/IMG_7125a.jpg) (http://postimage.org/image/28b17uxlw/)
The next series of photos show the pattern being produced from a heavy card, prototyped with a light card, and finally marked and cut out of 8mm 'flexiply'.

The final photo is an example of the law known as 'Murphys'...the model needed a drain hole through the centre bulkhead, so I get out the 22mm flat wood bitt and proceed to drill through the bulkhead..."you should drill it from both sides," advise the members helpfully. So......WHO put that wood screw THERE??? The same person who was drilling the hole and the same person who should have checked there were no screws in the way...
Being a genius should be a full time occupation {-)

Good progress Alan and helper monkeys. :-))

Your last image indicates that you have a water vole in residence! O0

Have you worked out the effect of the water volume pumped into the centre section against the overall displacement of the vessel? From the images posted it looks to be considerable and should bring her down to 'gunwhales awash' position easily. It looks to be a very sturdy build so far and a vessel that's built to last. Almost as bombproof as the original. :-))

Keep it coming and Happy New Year.

Hi Yarpie,
We have put our best scientific minds on this problem, if it sinks to the bottom of the test tank when pumped down, its got too much water in it. Therefore, next time, we will use less water.
See, scientific :kiss:

Title: Re: SS Ohio tanker build, Pedestal convoy.
Post by: unbuiltnautilus on December 30, 2010, 05:37:20 PM
The plan is to test the model with both ends, bow and stern buttoned up and watertight, in our 9' test tank ( TWO baths glued together, dont do nothing by halves down here in Portsmouth! ). We slowly fill the model up , if there isn't enough bouyancy on board, we will fit foam blocks into the centre section as needed. Rather like ballasting a model submarine. The foam blocks can be used to trim the model to port or starboard slightly, as well as altering fore and aft trim as needed. Once we are satisfied with the trim of the model flooded, the blocks can be permanently bonded into position.
Well, thats the plan....

Old Dodes,

nice image of the OHIO being shepherded into Grand Harbour.

Would you consider sharing your idea of tethering the two destroyers with us online?  I'm interested insofar as the two ideas stumbling around what remains of my brain are getting somewhat lonely! ;)  (They are: 1. using the idea of outriggers to trap a projection under the destroyers keels, and: 2. some sort of electro-magnetic means [which can only be tested once the ships side is fitted to OHIO]).

Both of these options have been discussed earlier in the thread, but it is both refreshing and encouraging to hear that somebody else is interested and committed to the cause. :-))

Happy New Year to you. :-)

I was thinking of a U shaped bracket in the vertical plain to fit abreast of the destroyers forescastle brake attached to the tanker and on the horizontal plain another bracket for the destroyers stem to lean on. This way the destroyers do not have to be modified in any way and with the vertical bracket that far back on the destroyer, the destroyer would be held fairly firm. The brackets can be manually adjusted to give best fit. Also the tanker would be very deep in the water when fully loaded anyway as tankers have a lot smaller freeboard to a normal freighter as they do not have cargo hatches to worry about, so she should not go much deeper through damage to the hull, also water will only go to the height of the hole after that the oil stays and gives some flotation. As I say it is only an idea, I expect knowing Alan he has researched it all out and has his answer to all the problems. Myself I am looking forward to seeing his display, as the Pompey boys have a reputation for giving very good displays.

my only concern for having boats attached physically would be what would happen should thte tanker start to sink too far , does it then take the other two vessels down with it ? maybe  the " support vessels could have a radio operated shoot bolt to locate into an open topped slot in the tankers sides , should the tanker sink too far the shoot bolt will be free !

Thanks for the input, the main issue with the design of this system is that the draught of the Ohio will alter through the display as water is pumped into the model following the simulated attacks on the fleet. The method used to secure the destroyers will have to involve something that, preferably remains invisible at both light load and deep draught. Contrary to popular belief, I dont yet have the answer to this one as it involves not just  the Ohio model but also, at least two of the teams destroyers. therefore , the request to drill holes through their models will need some discussion!! Now back to the new year celebrations, JD and lemonade tonight...

the bolt idea is a good one but you need to be lined up in the right spot to fire the bolt, and to do this from a distance could be a bit of a problem at best.I believe a post in the bottom of the destroyers and a v shaped bracket on the tanker would be the best and simplest option to do,as then the two destroyers only have to come along side and keep going forward to they hit the v bracket on the tanker.  When the two boats are along side all they provide is forward momentum as the tanker doses the steering and braking

Hi ya

Have you thought about considering magnets to secure the two destroyers to the side of the tanker?   

When I used to work in some heavy engineering industries - around open pieces of machinery - there used to be steel safely cages.  The doors on these cages were always kept secure using strong horseshoe shaped magnets.  Knowing that megnets of this strength are available; I would suggest 3 of the magnets are placed both port & starboard on the insides of the tanker and corresponding steel plates are placed on the inside of the destroyers - as soon as the destroyers come alongside the tanker and the plates then line up with the magnets - you may have some difficulty removing the destroyers from the side of the tanker.   

Another thing if you use magnets of the suggested strength you better put a warning up for people who have pace makers fitted.   In fact the possibilities are endless you could end up with a tanker which collects all steel garbage from the bottom of the lake.  {-) {-) {-) {-) mmmm food for thought there my friend.

i hear talk of electro magnets , possibly placed in the side skins of the tanker , with a corrisponding plate inside the destroyer hulls , which sounds much better than modifying the hulls of much prized destroyers , would also mean that by including a section of steel along each side of the escort ships then different models could be substituted should the need arise ?

magnets is a good idea but what sort of magnets and how strong will they need to be? and what if you can not put a metal plate in the boat,and would this not put extra weight into a boat that has a low free board

This afternoon I looked onto RS Components website, to look for door magnets that we used to use at work - cos I know they are very strong - there are several magnets on the site which are equivalent to the safety magents which we used to use.   Also, I noticed there were elctro magents used for safety doors - the voltage on these varied from 24 volts to 230 volts.   24 volts I should imagine would be no problem with 2 x 12 volt batteries linked together.   Drawback though - price - bit heftily priced these electro magnets

bat44, good input man. :-))  As a destroyerman in reality (3 WWII destroyers during a 25 year RN career) and also as a model boat destroyer driver, I would go for the 'drop down post' method. The reason behind this is purely selfish. I own two of the half dozen or so destroyers that may be tethered to the side of a sinking OHIO.  I don't want to lose either. As in REAL SEAMANSHIP , when replenishing at sea (fuel or solids), or when two (or more) ships are connected by whatever means, a quick breakaway mechanism is ESSENTIAL. I had a friend die in the HMS FITTLETON disaster.

I have a highly qualified colleague looking into the possibilities of electro-magnetic connection but we have discovered a time lag when the magnets are de-activated. This could be between one to five seconds, so much work needs to be carried out in this field to ensure an instant breakaway, should it be necessary.

Another alternative suggested is the horizontal tube running along the keel method. There is definitely mileage in that too.

Thanks everybody for your input in this little conundrum. Perhaps it may have been better for our little display team if the actual OHIO had not been so stubborn and had relented and sank following the massive damage she received. %)   But therein lies the challenge. ok2

Post by: triumphjon on January 09, 2011, 09:24:28 PM
re the electro magnets , at least its not quite so critical as to the location alongside , as a realativly large length of steel could be placed along the inside of the destroyers hulls , it would also pay to fit this along both inside faces thus making vessels universal to whichever side they were needed ? would fitting extra bouyancy in the destroyers help with peace of mind ? i see the offshore racing guys fit pool noodles inside there hulls !

Post by: bat44 on January 10, 2011, 10:05:06 AM
fitting extra buoyancy can be used but only works if the buoyancy is in the water , and the racing boys and girls put buoyancy in their boats in case they have a racing incident to keep their boats afloat if they take on water.Any way any one heared the old saying......

If you see any photo's of her plus a short movie film taken of her entry into Malta, she would appear to be down to her loadline. But if she was main deck level after the initial attack you are talking about 3 foot above her loadline, but I believe she had a hit in her engine room which put out her m/engine plus splinter damage to deck etc. I do not know what her damage was but she did break her back after discharge, but that can be caused by incorrect method of discharge stressing the hull already stressed by bomb damage to hull structure etc, as I have never seen a damage survey report on her.

Hi Old Dode's   as to the distance of loaded freeboard to her main deck i do not no, but i will have a word with unbuilt and ask him as he has the plans for this build and he can work it out for you. As to this model having a load line painted on is a good question if the real one had one then we would pot one on as well. But we will git to that at a latter date as we have enough things to do as it is.

If you see any photo's of her plus a short movie film taken of her entry into Malta, she would appear to be down to her loadline. But if she was main deck level after the initial attack you are talking about 3 foot above her loadline, but I believe she had a hit in her engine room which put out her m/engine plus splinter damage to deck etc. I do not know what her damage was but she did break her back after discharge, but that can be caused by incorrect method of discharge stressing the hull already stressed by bomb damage to hull structure etc, as I have never seen a damage survey report on her.

The Ohio was torpedoed midships  quite early in the action, leaving a 25' x 30' hole in the side. She then suffered a number of very near misses from bombs which put further major stresses on the hull. A bomb hit the ship in aproximately the same place as the torpedo hit which almost definately resulted in the ship breaking its back. A further hit on the bows resulted in fires that were quickly extinguished. A Ju87 dive bomber and Ju88 bomber also crashed onto the ship during the action. She was decks awash as she approached the minefield outside Valletta harbour but her main deck appears to be about 3' above the sea in the photo of her entering the harbour. The crew were also forced to abandon ship twice during the voyage, both times electing to re-join the ship when she failed to sink. Quite an achievement, i think.
As far as load waterlines etc, I will check our drawings and report back...

Just thought, the crew would return if she did not sink, for no other reason that when they abandon a ship, they go off pay. Because in the merchant navy you sign on the ship for the voyage only, once off the owners stop pay immediately.

First, the stern section. Now buttoned up with the last piece of flexiply fitted. At first we were not sure about an 8mm thick bulwark being exposed, and were going to fit a bit of 1.5mm ply and fair it in. However, at the moment it looks fine.
(http://s2.postimage.org/pxryckv8/IMG_7577.jpg) (http://postimage.org/image/pxryckv8/)
We have fitted two M6 brass bolts through the bottom of the bow section, and two through the bottom of the stern section. These are just in case we have to bolt on extra ballast low in the model. There is a possibility that the model may become unstable as it floods with water. If so, we can either add foam into the centre section ballast tank, or ballast weights fore and aft... as I say, just in case ok2

That makes all the planning, building, logistics etc all the more worthwhile tobyker. We will bear in mind the 400 personnel killed in action in Pedestal during our display. Their sacrifices are still remembered, not least by the people of Malta who celebrate the arrival of those five gallant ships and their 45,000 tons of supplies to this day. Every August 15th, the ships in Grand Harbour sound their sirens and horns for a full minute in honour of the "Santa Maria Convoy" that saved the island. :-))

The build continues;
Firstly, having checked the drawings, i can confirm depth from main deck to load Waterline ( the land lubber in me feels this is the correct term for how far you fall before you get wet if your boat is full of stuff! ) as 10' on SS Ohio. I have marked this on the following photo but may ballast the model to the lower mark, for the sake of visual interest as she settles in the water.
(http://s1.postimage.org/2w582m5ok/IMG_7708.jpg) (http://postimage.org/image/2w582m5ok/)
This is the day it starts to look like the prototype. Firstly the bow is trimmed and sanded.
(http://s1.postimage.org/2w5myga4k/IMG_7678.jpg) (http://postimage.org/image/2w5myga4k/)

(http://s1.postimage.org/2w5olzmmc/IMG_7680.jpg) (http://postimage.org/image/2w5olzmmc/)

(http://s1.postimage.org/2w5tklo3o/IMG_7677.jpg) (http://postimage.org/image/2w5tklo3o/)
Its times like this that you just have to stand back and stare at the model, saying repeatedly.." I like the look of that..."

The other major job of the day is side plates on the centre section..
(http://s1.postimage.org/2w6a3z51g/IMG_7683.jpg) (http://postimage.org/image/2w6a3z51g/)

(http://s1.postimage.org/2w6brihj8/IMG_7684.jpg) (http://postimage.org/image/2w6brihj8/)
Yay!! Grahams back on the build.... The sides are dry fitted and the internal bulkhead positions are marked on the inner face of the ply. As you can see, we are placing the ply painted side inwards. this is to ensure the timber is waterproof INSIDE the ballast tank section. The paint is ground off the ply anywhere it is going to be bonded, to ensure a good mechanical joint.

(http://s1.postimage.org/2w70kkoxw/IMG_7700.jpg) (http://postimage.org/image/2w70kkoxw/)

(http://s1.postimage.org/2w75j6qf8/IMG_7695.jpg) (http://postimage.org/image/2w75j6qf8/)
The sides are first bonded, and then screwed in position, the sides are manouvered into position by eye and by touch, the screws are placed into the pilot holes and tapped into position using a 'dockyard screwdriver' ( usually referred to as a hammer by a chippy, and a dockyard screwdriver by those who worked within the confines of HM Dockyard, Portsmouth...."Just hit it!" ).

Finally, with the bow block sanded to shape and the sides on, she is starting to look the part. However, with foaming glue oozing out of various parts of the model, we cannot bolt her together for an end of session photo {:-{
No more updates this week, as we are off to Alexandra Palace on Sunday to eat bacon rolls and photograph the London skyline...again :-))

(http://s2.postimage.org/314dohfhg/DSC00798.jpg) (http://postimage.org/image/314dohfhg/)

so after the 1st cup of tea and donut's it was time for work. Because  the glue we are using is new to us and the way in which we are using it we thought it was safe to back up the clue joints with some epoxy on the back and front of the boat
(http://s2.postimage.org/316eg4p7o/DSC00784.jpg) (http://postimage.org/image/316eg4p7o/)

to do this we had to open the glue joints so we could pour some epoxy into the joint

Its progressing well. The main hulls are complete, except for filler and many coats of sealer, and it is currently just over 98.5" long!!

(http://s4.postimage.org/1xkwxn9t0/IMG_8092.jpg) (http://postimage.org/image/1xkwxn9t0/)
I am not confident of a 100% waterproof seal between the panels on the bow and stern. Therefore following the sterns milling out on our last visit, it was now the turn of the bow. The joints are milled out to a depth of 1/8" wide and 1/8" wide. These are then filled with fast drying epoxy resin adhesive, and finally filled over with body filler.

The other job was the final finishing around the bridge area. This part of the model contains the control box for the bangs and flashes. This needs to be secured against moving too much, therefore we cut the upper hatch as an interference fit around the control box.
(http://s4.postimage.org/1xlvnxk6c/IMG_8100.jpg) (http://postimage.org/image/1xlvnxk6c/)
The days work finished, all that is left is the posing shot %). Note the plan in the background, it is out of its tube again as we contemplate the bridge detail.
Just a brief sketch to outline the planned positioning of everything within the model.

i have a commercial sized spray gun and compressor should you wish to spray the hull ?

Many thanks for the offer, I still have a commercial sized spray gun and compressor which I borrowed from a fellow member about 2 years ago, to spray an R2D2, and he wont get it back until Ohio is grey!!

So that would require chopping a 10" chunk out of the middle to bring it to 1:72 scale then, in line with the rest of the convoy ..... ;D

I know .... I know..... shadduppa you face!!! :embarrassed:

SS Ohio was 515ft long so the scale is roughly 1:62.

Now to go and get a life. :embarrassed:

Trip to local model shop. Conversation as follows..."Why dont you sell 1/62 scale figures, there must be a market for them, I want them?? and have you got window frames to fit the model ? NO...what sort of model shop do you call this?!"
Well, thats off my chest >>:-(

The ideal model shop stocks one of everything available, everywhere. Then someone asks for 'two please', and you have to 'order it in.'Maybe they should stock ten of everything available, everywhere. Then someone asks.......... ;)

That isn't a reasonable proposition - that means you have to store 10 of everthing - most model shops are small business premises and
the overriding thing would be cost probably having to pay in advance for all these bits of kit in the hope of selling them sometime soon.
Could cause serious problems with cashflow then no modelshop.

Filling and sanding, again. Here we are addressing the aft to midships join, this wasn't 100% and needed some attention. Parcel Tape makes for a really great 'easy release' surface, so it went on one side of the joint, while filler went on the other, wind the two together and wait for it to cure.

well Thursday has come and gone and what did we do ?........ not a lot, the idea was to get the hull ready for some paint in the next couple of weeks but we were court out by the new filler we had started to use
(http://s2.postimage.org/xnhb8d9g/DSC00845.jpg) (http://postimage.org/image/xnhb8d9g/)
here we are mixing the filler before we use it, yes we need that much.As it was a new type of filler we were not sure how much hardener to use so we went with what we know from the other fillers we have being using, 
(http://s2.postimage.org/xp4ukv1g/DSC00854.jpg) (http://postimage.org/image/xp4ukv1g/)
OPS ....this is what happings when you do not put enough hardener in sitting around with hot air guns getting the filler to go of.Well thats all we could do that night, so after a cup of tea and an hour of sitting around talking we went home early for a change. So you will have to wait for sunday for the story to be carried on

We are at that stage in the build where nothing much seems to be happening week to week, currently filling and sanding.
(http://s3.postimage.org/20ijebgk/IMG_8233.jpg) (http://postimage.org/image/20ijebgk/)
The bow section is here being filled where the vertical 'planks' were fitted, some trouble was encountered with the filler not initially going off, a combination of low storage temperatures and not enough hardener. This is being resolved by warming the filler before use, and not being so 'tight' with the hardener.

The other part of the model needing filler is the joins between the three sections, here the bow to midships joint is being addressed. We are using brown parcel tape as a simple release agent on the side of the joint not needing filler, works so far...
The second image shows the bottom profile of the model, its underwater and doesn't need to be pretty, although what this does for the hydrodynamic efficiency of the hull, who knows :o

In my defence, I had just come back from felling Redwoods for the next part of the build, got chased by a bear, fell down a ravine, joined the Mounties, stopped illegal liquor being smuggled into Gosport, canoed through the back woods pursued by rednecks, found a dam blocking my way, invoked the ancient forest gods to bring a flood to destroy it, this failed, so I contacted 617 squadron, got an ansaphone message "closed due to lack of interest", so went round the dam, arrived at clubhouse late to find THEY hadn't put enough hardener in the filler, hence, the heat gun :P

We are back on the build.
First up, i wasn't happy with the bow profile compared to side views of the real ship, this coupled with some very good top views of the model on display in Malta indicated a slight change in profile would be acceptable.

Although one or two of the images are out of focus, I hope it gives an idea of the process.
Firstly, a plywood profile was cut out of 8mm ply, this was drilled to accept 4mm stainless pins which were drilled into the bow.
This was firstly epoxied, then secured with the green Glassfibre Repair Paste, Then filled with Marine Filler... in fairly rapid succession. The different adhesives/fillers were applied as soon as the proceeding materials had started to gel off. The bows then proceeded to generate a healthy amount of heat!
The finished bow has a far better profile and shows to good effect the excellent finish obtained with the Marine Filler ( i'm still not buying any  ok2 )

Post by: unbuiltnautilus on February 24, 2011, 06:08:03 PM
I am ,apparently a fussy git when it comes to certain details. Hawse pipes, for example, should be fitted from hull to deck, I dont like seeing an anchor stub glued to the bow of a model, having been sheered off in a collision, leaving a stump of epoxy or cyano.
So, lets drill holes in that pristine bow :-))

To have a fighting chance of getting all the holes in the right place a block of timber was drilled as a pattern, this was marked with pencil lines, aligned with marks on the deck, and clamped in place. A drill then carefully did the business, until it emerged from the hull side. A brass tube was then slid into position with epoxy smeared around it, Success :-)) ( the first time and the third time, don't ask about the second time!!)

As with the bow profile, I felt we could improve on the stern profile, looking at photos of the original vessel being towed into Grand Harbour, it looked      different. So, out with the timber block, Jelatung this time( about time we used some of it up!).

Once again, Marine filler was used, giving a great finish, note that the profile of the model changes between pictures 1 and 3 as Mark sorts out the 'slight' imperfection visible on the port side of the model.

I have been hinting at 'plating' detail for a couple of weeks, it is usual when this happens to receive much mocking and complaints about slowing the project down, for the sake of  'pointless' decoration. However, I like pointless decoration, even on a model destined for soot, rust and gunge throughout its life!
And it was going on, no matter what :-).
I wanted to try out a technique described by David Merriman, a model sub man from the US of A, involving filler and tape to create raised plate detail, so starting small, I taped up around the hawse pipe outlet, two layers of masking tape, and applied a thin skim of filler, this was then rubbed down with the tape in situ, avoiding rubbing too much away.

So far so good, the last picture once again shows how nice the finish of Marine Filler can be ( still not buying any...).
With the test out the way came the big one, right down the hull side, both sides...

This time a different approach was forced on us, it was getting late, so, off with the tape as the filler gelled off....................................TBC

Agreed Tug --- Kenny, different technique, never saw it myself either.

Recently I glued 0.25 mm plasticard "plating" to my 1:72 scale HMS RODNEY. Reasonable finish. See here:

http://www.modelboatmayhem.co.uk/forum/index.php?topic=27664.50

As both models belong in the same Team, it will be fascinating to compare the merits (or de-merits) of each technique. But we must bear in mind that RODNEY will not suffer quite such a pounding that OHIO will sustain during pyrotechnic displays.

Watch this space ...........  %)

I'm also in full agreement with the addition of the plating effect on the OHIO. :-))

We are using bog standard car body filler, available from any car accessory shop. The tape is 2" masking tape laid two strips thick to give a bit of depth. This is removed either when the filler has been sanded down, as with the hawse pipe, or when the filler becomes 'green', just before hardening off, when it can still be trimmed with a knife. So far it is sticking like the proverbial, as this is how it would be used for automobile repair work. Next week we will be trying a variation on the theme, laying the tape to represent one side of the plate only, the filler will fair into the hull on the other side of the 'plate', smoothing away to nothing.
Ultimately, this effect will help when it comes to weathering the hull, as washes of rust and chipping can be applied to the plate edges to greater effect than to a smooth hull.
Thanks for the interest...

Okay,back to the build.
Yesterday, in an all fired rush to prepare the scruffy looking, dust covered heap for the Midhurst Modellers Show this coming weekend (27th Feb, The Grange Centre, Midhurst, Darkest Southern England.) we tidied, vacuumed and sanded.
1) Pumps fitted, these were bolted in the case of the 'pump out' pump, and siliconed in in the case of the 'pump in' pump. The 'in' pump is flush with the bottom of the hull and fitted into a 2" dia hole. The 'out' pump is raised off the tank bottom by about 3mm and secured with stainless M4 machine screws.

(http://s3.postimage.org/2mqgw70xw/IMG_8529.jpg) (http://postimage.org/image/2mqgw70xw/)
These pumps are Whale Industries marine bilge pumps and will pump up to 50 litres a minute, if you ever want a firefighting monitor pump, these are the kiddies :-))
2) The rudder is next, this is loosely based on the Schilling Rudder concept, with a wedge at the trailing edge to deflect water sideways similar to a Becker Rudder, but without any moving parts. This started life as a commercially available rudder which then had a copper blade soldered to it using Plumbers Solder, hammered to shape, and filled with Glassfibre Repair Paste before being trimmed down with various sanding implements :D

3) Push Bars, these are for the two Destroyers to locate into, as they come along side for the last part of our display. The bar is 4mm Stainless Steel, the tubes are redundant 8mm dia propshaft outers and are drilled through the model BELOW the lower hull, but through 3/4" of timber sides hanging below the flat bottom.
These bars are removable for transport and for playing down the lake on a sunday. Only one has been fashioned so far.

(http://s4.postimage.org/2g6fp621w/IMG_8545.jpg) (http://postimage.org/image/2g6fp621w/)
The Destroyers have an aproximate beam of 5 1/2" and will have a pin protruding below their hulls at the centreline. The 'vee' in the rod has been placed at 3 1/2" from the hull side to 'stand off' the destroyers slightly from Ohios sides, allowing them a little manouvering ability and to protect their much nicer detail work from damage....Thats the plan anyway %%
Anyway, see some of you at Midhurst :-))

Todays jobs, add a bit more plating detail to the bow. This time I filled up against one side of tape only, above and below the existing plate line.

 A bit of flattened tube and a hole to fit...
The next job entailed fitting 'through routes' for the cables that will serve the underwater pyrotechnic effects. These have to run from under the hull to 'on deck' terminals.

 After a short hiatus ( I could have shown 2 weeks of cellulose dope drying, but even I sometimes know when to draw the line!! ) we are back with some new photos of the build.
(http://s1.postimage.org/wcq2l138/Ohio_paint1_013.jpg) (http://postimage.org/image/wcq2l138/)
First off, a waterline marker, home made, cheers Jim :-)) Consisting of ball races for wheels, vertical bar in aluminum and a hardwood block drilled to take the vertical bar and horizontal pencil.

(http://s1.postimage.org/wdlhsmh0/Ohio_paint1_018.jpg) (http://postimage.org/image/wdlhsmh0/)
The next three images are meself and John painting the bottom and deck of the model with red oxide primer, this particular one is from the car accessory guys at Halfords. It dries quickly and is pretty tough when on the model.

(http://s1.postimage.org/wedlxiv8/Ohio_paint1_023.jpg) (http://postimage.org/image/wedlxiv8/)
The next image is a close bow shot and shows the plating detail to fairly good effect, its a pity that, so far, only a small part of this effect has been painted, just visible in the red paint.
(http://s1.postimage.org/wf7dlrr8/Ohio_paint1_019.jpg) (http://postimage.org/image/wf7dlrr8/)
Final image of the night. With the decks red oxide and below the waterline the same, it was time to call it a night. Pay close attention to the first stages of the hull painting because I will be incorporating a 'weathering' effect into this stage that is both simple to do and looks effective. No clues yet though...
Next job will be the plumbing for the ballast pumps, as the plan is to tank test the model on the 27th March %% %%

Progress to date.
The model is now painted all over, almost, and is nearly ready for its first dunking this coming Sunday.
(http://s4.postimage.org/ixzwc49w/IMG_9284.jpg) (http://postimage.org/image/ixzwc49w/)
Plumbing is being installed for the two pumps. The 'in' pump has to be fitted with a 'U bend' to prevent unwanted water entering the model when afloat. These impeller pumps are open to through flow of water at all times and the outlet pipe is perilously near to the load waterline, hence the 'U bend'.

QUESTION... What colour would the decks be on a WWII Tanker that has recently been painted grey over its hull sides and superstructure??? I would assume that the Red Oxide finish would be like a beacon to roving enemy aircraft. Would the grey continue over the horizontal parts also, or would the shipyard/dockyard still have the luxury of deck paint to hand??

Given the history of the fast requisitioning of the OHIO in Scotland by the Navy Department, I would imagine she was painted all-over grey, with perhaps a slightly darker shade for the decks etc.

I have seen images of the funnel ok2 which demonstrates the speed of the paint job. The Texaco logo can still be faintly seen under the rushed grey paint job.

It was well known by both the Allied and Axis powers that this vessel would take part in one of the most strategic convoys of WWII, and that she most probably (and did) come in for undivded attention from the many attacking forces. To this end she must have been considered as 'sacrificial' so any elaborate paint job would have meant time and money ill spent.

As it happened though, it was probably only her paint job that kept her in one piece and able to enter Grand Harbour in the epic way she did. %)

All model photos that I have seen depict her in overall grey. :-))

Hope this is of help.

  For what it's worth. My father was an engineer on Standard Oil and Anglo American tankers in the North Atlantic and Malta service during the war. Right at the end of the war he took a few photos on his, then, current vessel, Seminole. The shot is looking aft from the center house. You can see the distinct shade difference between the vertical house walls and the deck. He said the vessel was overall grey with a red oxide deck. I've been building a model of it and this is the scheme I was going to follow. You'll notice the 20mm turrets on either side of the aft house. There was a 40 mm on the foc'sale. Also notice the stack colours.

  She is in the Bay of Biscayne. In ballast. My father said there were canvass tube extensions to put over the open vents and run up cabling to a height well above the catwalk to prevent ingress of water in rough weather. Don't forget, you went to Britain loaded and came back empty in the war.

Excellent deck clutter reference, thanks for the input so far, guys. I may need to do a bit of research into the speed of the re-equipping tha SS Ohio experienced when she arrived here from the U.S of A. The information may simply not be available and I will have to go with the best 'average' I can find from a number of vessels. Will seek out colour footage on my Roland Smith DVD tonight, see if I can glean any clues.

regardless of colour, I note that the decks seem to have a gloss sheen to them, while the superstructure is flat matt. this could be down to water across the deck, but i am not sure. Any ex tanker people out there can confirm gloss decks? ( also flues or funnels? This is a question that MUST be resolved....local team humour >>:-()

 A few entires ago I responded to the open vents and vent bags that were installed in rough weather. I've found a couple of references to these canvas bags. they were also used to assist in venting holds in ballast before venting fans and similar apparatus were in use. The Seminole was a 1925 vessel.
The first reference is from the book "TANKER PRACTICE" by G.A.B. King,, "The construction, operation and maintenance of tankers".


(http://s2.postimage.org/gyjsnbxg/windsails.jpg) (http://postimage.org/image/gyjsnbxg/)



(http://s2.postimage.org/gyn3q0x0/windsails_2.jpg) (http://postimage.org/image/gyn3q0x0/)

The next reference is from a web site giving personal recollections of individuals involved in WWII. This one was deck crew on a tanker :

http://www.bbc.co.uk/ww2peopleswar/stories/79/a2152379.shtml

A quote from the write up:

"When a vessel is fully loaded with aviation spirit it is well known that a torpedo hit results in a blue flash. When it clears there is absolutely nothing left. An even worse situation presents itself when you have fully discharged the cargo as you are then a floating gas bomb and it is essential that you fit windsails to every tank to discharge the gas and that was the position we were in."

From the following site:  http://www.hnsa.org/doc/merchant/prelim/part3.htm

"In cleaning tanks by hand, the process consists usually of steaming the tank for several hours and then raising the tank hatches and washing the tanks with a fire hose, removing the water and refuse oil during the washing operation. "Wind sails" are then rigged to ventilate the tanks. Wind sails are canvas air ducts with large flaps on either side of an opening at the top. The flaps catch and direct the air through the opening at the top and downward through the duct and into the cargo tank. "

In 30 years at sea I've never seen gloss decks, most likely to be the result of water, (and probably an oil sheen!), but accommodation, certainly all I have know is painted gloss finish.......HOWEVER....... that is all much later than what is in the picture...

(http://s3.postimage.org/hzcu34qs/Tank_Test_009.jpg) (http://postimage.org/image/hzcu34qs/)
With the unusual bottom profile there was the chance of air pockets. the model was initially bow light, resulting in a nose up attitude which trapped air in the bows. This was soon released by pushing the bows down and allowing the air to escape out of the stern ( I am somewhat of an expert on this manouever O0).
(http://s3.postimage.org/i06lrdms/Tank_Test_011.jpg) (http://postimage.org/image/i06lrdms/)
"There, There, I wont let them nasty Display Team types hurt you......Thats my job!!
The model floated steady and stable, if a little bit 'light'. About 8lbs of lead was needed against the forward bulkhead of the centre section to level the model off. We ( I )  was in such a hurry when we plated the bows that no ballast was built in to the , now sealed, structure.
(http://s3.postimage.org/i3oalr5w/Tank_Test_015.jpg) (http://postimage.org/image/i3oalr5w/)

(http://s3.postimage.org/i5gskaf8/Tank_Test_030.jpg) (http://postimage.org/image/i5gskaf8/)

Hi atlam,

that could almost be read backwards as .............MALTA. :-))

Wonderful to hear from you sir, and I hope that you are well. April the first or not, nobody would joke about an event such as you endured all those years ago.

Perhaps, if you have the time and inclination, you would do us the honour of relating some of your proud recollections on this thread.

I'm sure that the Moderators wouldn't mind as its a very rare opportunity indeed.

And perhaps you could clear up a little conundrum that we have regarding the colour of the OHIO's decks during that fateful  and epic journey. (I know that you didn't really have time to study the deck colour then, as there were one or two other distractions going on at the time). O0

Once again, its an honour to hear from you.

Stay well.

Yarpie.

Okay, it floats, on with the next part...
The drawings I have depict Ohio 'as built'. I now need to modify the drawings to depict her as she entered malta in August 42.

(http://s3.postimage.org/5lvsc7pg/Steam_open_day_etc_273.jpg) (http://postimage.org/image/5lvsc7pg/)
The drawings are to a scale of 1/96 and will need enlarging, however I have chosen to draw the various fitments at this scale. Using the various images of Ohio as she approached and entered her destination, I have managed to locate the positions of the forward 3" gun platform, the aft 5" gun platform, the 40mm Bofors gun just in front of the 5" mount, and four of the six 20mm Oerlikons. Two flank the 40mm mount and two are on the outer bridge wings on a platform added, I assume, for wartime service. The last two 20mm Oerlikons are proving a bit of a mystery. I cannot locate them in the photographs and I believe existing models are inaccurate in their depiction of the ship. Help!

Onwards and upwards...
The forward superstructure is next.Scaling up from the plans at 1/96, I produced a card template of the lower bridge deck, then offered this up to the model and tweaked accordingly. As I worked up deck by deck, I removed parts from this original template as the decks become smaller, cutting the 1/8" ply decks as I went.

Then its offer it up, balanced on boxes, to see how it looks. The upper deck gun platforms do not match any other models I have seen of Ohio, as I believe these previous models represent her 'post Pedestal' while she served as a Stores Depot ship in Valetta Harbour. So, apart from the obvious deviations from scale to facilitate her special 'functions', I am still hoping for a good, scale representation of the ship at the time of the Pedestal convoy.

Sunday, and time for the rear superstructure decks. These are cut out of 1/8" ply sheet and are scaled up by 1.4 from the drawings ( and sometimes tweaked to fit the hull where 'variations' occur >>:-(). From the front of the vessel we have a 3" gun mount offset to port on the bows, two 20mm mounts on the upper bridge wings, plus the decks below that, aft is the boat deck with two 20mm mounts followed by the 40mm Bofors mount ( square ) and finally,the circular 5" mount at the stern.

It may not be running yet, but there is smoke from the flue! A home made 'Jim Special' smoke unit running at 12v and about 2.3 Amps. Notice the difference between the 22mm copper tube only, and the ( Patent Pending :-)) ) Pringles funnel as far as smoke volume is concerned. The smoke seems to linger in the tube, producing what appears to be greater volume of smoke.

Cheers, Pringles :-)) ( Not keen on the Salt and Vinegar flavour though, wrong colour for the funnel......)

OK we have planed it talked about it now comes the time to make it yes the front superstructure.The bigest problem was how to build with a camber and a curved front end.First we clued a 5mm spacer across the front access in the superstructure. then a big lump of filler is put over the Deck then the new ply wood Deck is put on top of this than bolted down to form the camber of the deck

The build goes on...
Next we have the bridge decks, these have a slight camber to them ( a quarter of an inch higher down the centreline of the model ) as detailed in one of Bat 44s posts. Now we had to start piling deck upon deck. This proved problematic as we had great difficulty measuring a vertical 'plum line' for the proceeding decks.

This deck had to be removable and provide the ( stiff ) structure off of which the upper decks would be profiled. Assembled with 5 minute epoxy it did the job, once unstuck from the not very protective masking tape.

(http://s3.postimage.org/2zq1le7k4/IMG_0851.jpg) (http://postimage.org/image/2zq1le7k4/)
The next deck was soaked in boiling water and clamped to dry over three days.

Next deck up, out with the Jelatung, best carving wood there is, and hoarded with the intention of using it on the next project all the time! Well, this is the next project..

The fore and aft parts were trimmed to fit first, then epoxied into place. 1/8" ply was then epoxied in as sides followed by 1/4" spruce stringers along the upper edge.
The upper deck was then epoxied and clamped into position.
Finally, the navigating bridge was assembled, this is rectangular, so could be assembled with cyano glue first, then beefed up with epoxy when assembled.
The diagonal timber is forcing the bridge front back into shape after I clamped all the curve out of it!!

The reason for the 'lift shaft' running up through the bridge is to allow an 'Arm/Safe switch and indicator lights to be fitted from the control box below to the bridge above. This allows our Safety people to arm or disarm the model quickly without having to open any hatches, something I would advise anyone considering pyrotechnics or fire effects on a model, to fit.

Miscellaneous bit first, suppiled by a fellow club member, giant phosphor bronze washers now used as load spreaders wher the hull sections bolt together.
(http://s3.postimage.org/2zvlpf7b8/IMG_0898.jpg) (http://postimage.org/image/2zvlpf7b8/)
Next, with the bridge nearing completion it is on with the aft boat deck. This is where the radio equipment is that controls the models standard functions, this will be splash proof as I feel the model may get 'splashed' occasionally ;)
To aid construction of this first deck I have decided to raise a submarine style hatch off of the deck of the model, pictured are the 1/4" plywood surround and the 6mm acrylic lid.

(http://s3.postimage.org/2zx2mmb44/IMG_0955.jpg) (http://postimage.org/image/2zx2mmb44/)
These will form the 'locator' for the hatch. 10mm plywood will form the lower part of the hatch, this will be bonded to the 1/8" upper boat deck, finally the sides will be fitted when this is all secure. It makes a change not having to worry one jot about the weight of the component parts :-)

One bit leads to another bit. The build of the boat deck relied on a number of parts completing at once. This didn't quite happen, so the pioneering 'measure, cut, stick, measure, cut, stick' build technique was interupted by donut and coffee down time!

Been looking at my copy of "Malta Convoy" (Shankland & Hunter, 1961) p 189 " the 6-inch gun at the bows twisted in its mounting and was put out of action." "On the bridge, the bofors had been in action for nearly half an hour".. ( Gunner Billings shhots down a Ju 87 which crashes into the side of the ship) Do you have a copy of this book?

Also p 201 " Another bomber came screaming down towards the OHIO fro the starboard beam. The lower bridge oerlikon opened up ...... I bet it's hidden by the tug's white funnel in the "entering harbour" photo.(Can't see a 6" on the foredeck though - wonder of that's a misprint?).
Title: Re: SS Ohio tanker build, Pedestal convoy.
Post by: unbuiltnautilus on May 19, 2011, 08:08:40 AM
I dont have that book, however, I believe the fit of weapons is as follows;
3" gun on a raised platform offset to port on the focsle.
Two single 20mm Oerlikons port and starboard on the fwd upper bridge wings.
A single 40mm Bofors gun (probably an early land based mount) aft of the funnel in a high box shaped mounting.
Two single 20mm Oerlikons mounted port and starboard just forward and below the Bofors gun.
A single 5" low angle mount at the stern, on a large circular mount.
There are listed two more 20mm Oerlikons mounted somewhere on the ship, other models show a single gun mounted on the upper bridge deck starboard aft, however none of the photographs support this. We have spoken to an ex-crewmember, now a fellow mayhemmer, who remembers them being mounted directly to the deck, port and starboard, at the foreward part of the aft boat deck. All the images so far seen are jumbled in this area and difficult to make out, however, that is where I am anticipating mounting the last pair of guns.

Another night of activity resulted in a lot of mess. I was on filler duty. The aft superstructure had already been clad in 1/8" ply, however not at the 'corners'. Too tight for the ply. Eay fix, filler. I hate filler, this particular brand goes off with a slight tackiness to it. However, as long as you are cautious sanding down ( I use coarse grade Permagrit tools) and dont apply too much pressure, the material cuts down fine without clogging the tool.

Last night was bridge work.... we need a funnel , so I took on that task. Mostly built out of 5mm balsa sheet. The first horizontal part was out of boxwood, all other balsa frames were measured off of this first part and glued in situ, ensuring everything was square as I worked up the funnel. The funnel cap is 5mm ply with a 1.5mm ply addition underneath this part where I screwed up and didn't make it wide enough for the job!!

The funnel will be clad with thin timber, either plywood strips or spruce strips, depending on what I have to hand. I may have to sleeve the funnel internally to avoid any heat damage from the smoke unit.
Helen and Mark have been working on the bridge bulwarks etc. Yesterday mark was busy working on some sort of Flash Gordon hat that he purchased at Alfold on sunday, leaving Helen to continue with the bridge work.

Gun Tubs.... These are assembled using 3mm ply for the bases, and a combination of 1.5mm and 0.8mm ply for the armoured sides. The thinner ply where needed as it bends easily. The supports under the Bofors mount (the square one) came from the club broom. Hopefully nobody will notice that it is 2" shorter than it was last week :}

Hi, yes I caught it last sunday on Yesterday.( I think that makes sense?). It is a short but useful clip, that I have been watching repeatedly. It helps that we have a copy of the 'as built' plans of Ohio, as it helps when identifying blobs in photographs!
The build is progressing, however our plans to have her ready for this years Weymouth show in July have gone for a burton, at the moment we are hoping to be on the water locally at our Canoe Lake display in August, even then, that is pushing it....

Cheers Pat, Trimphjon has already put me on to this site, excellent reference which has already highlighted a couple of variations that we missed using builders plans and old photographs only. I have to balance the amount of scale detail that can be added within the restrictions imposed on us regarding the pyrotechnic effects. Fireproof plumbing is what we are currently examining!

Welcome from the Portsmouth Yard, dormant for a few months now as other projects have taken precedence. However, the build is back on!
The first problem encountered this week was this, I am building a Pyrotechnic Effects model, not a scale one! Sounds obvious, but I keep forgetting. Monday was the fitting of the walkway (highway?) from the main blocks of superstructure aft to midships, over the tank deck. This has been detailed in a fantastic build/re-build thread elsewhere on the forum, featuring an RFA Tanker, and whose authors name I cannot remember! However, this aint no scale model, and that sort of super detailing will just get blown to little tiny bits the first time I over stuff one of the charges! In the interest of survivability I have instead opted for...
(http://s8.postimage.org/6g6o1d13l/IMG_4021.jpg) (http://postimage.org/image/6g6o1d13l/)

(http://s7.postimage.org/t1taae0p3/IMG_4022.jpg) (http://postimage.org/image/t1taae0p3/)

(http://s7.postimage.org/cja4vb2mf/IMG_4023.jpg) (http://postimage.org/image/cja4vb2mf/)
Only the best quality Aluminium 'U' section cut and screwed and bolted to fit. It is held down with a combination of stainless self tappers and M5 stainless bolts into captive nuts. Todays advice... do NOT fit your captive nuts in place with cyanoacrylate as a) it isnt strong enough for the job, and b) when it drops out of the bottom of the deck it IS strong enough to bond itself to the stainless bolts. The whole assembly now rattling up and down through a hole in the deck. I have invented a whole load of new swear words if anyone wants to borrow them for a special occasion, just drop me a line :}
Usually, tankers are adorned with large 'NO SMOKING' signs, this one will have 'TRIP HAZARD' at the end of the walkway, due, mostly to all the screw and bolt heads sticking up!
Next was davits, ten in total. These are being made from a material called 'Foamalux' which is used by sign writers. I imagine it is a cheaper alternative to acrylic, as the surface finish is not as good. One advantage is that it is mildly flexible, which is good news for davits. these seem to spend much time being knocked, bent and dented during transport. I have already built a bigger set for the CHANT tanker, posted elsewhere on the forum, and these have proved tough over the summer season. So now was time to scale down.
(http://s10.postimage.org/k1ewgnuk5/IMG_4019.jpg) (http://postimage.org/image/k1ewgnuk5/)
These are 'in build' at present, cutting two at a time from two sheets of material taped together ensures they are paired and matched visually.

I was  reminded of your build today, was watching Yesterday channel about convoys and UBoats etc, when they showed some pics of the Ohio going into Malta, What a mess the bow was at the waterline, the stem bar was there but most of the bow going back about 20ft was missing.

It will be on the water next year.
The bow damage you talk of was probably Brisbane Star, as opposed to Ohio. I have found photos of both, including a fore shortened Brisbane Star following her temporary repairs. Ohio still suffered bow damage as shown in the famous photo with her tied to the two destroyers.

It will be on the water next year.!!!!!!!!!!!!!!!!!!!!!

The bow damage you talk of was probably Brisbane Star, as opposed to Ohio. I have found photos of both, including a fore shortened Brisbane Star following her temporary repairs. Ohio still suffered bow damage as shown in the famous photo with her tied to the two destroyers

As the model is in pieces and the centre section is all ballast tank, I will be fitting two receivers, one in the aft section and one in the centre section controlling pumps and flash bangs. This saves me fitting cables through waterproof glands etc. I will be using a Futaba 7 channel 2.4G Tx with two Corona Receivers.
The aft section will have rudder and motor control, plus some method to control the gunfire effects through the AA guns.
The mid section will have two channels to pre-select, then fire the pyro effects, plus a third channel operating the pump up/down functions. I may also light up the two Oerlikon guns on the bridge wings in conjunction with the aft AA guns, however it may get a bit crowded with heavy gauge wire to the effects, light weight wire to the pumps AND fibre optics up to the AA guns. Plus an on deck arm/disarm switch of course...All fitted inside a waterproof box.

gday ,
 lover the build , impressive model
i would like to recommend you fit 2 pumps , especially in the pump out side of things , after all, how do you bail it out ?? if the pumps don't work ??
these pumps can be very reliable , but ,they are very basic , and free flooding too , which means water sits in them all yr round .
 you could also fit some form of manual drain cocks ,as back up .
 a idea i want to try is , fit a false bottom in a big model ,on the water line ,or 25 mm below it , then cut the bottom out of the hull ,to allow it to free flood , water proof well , but this idea does away w the needs for pumps ,as the water drains well from the hull ,as you lift it from the water , looks like it will work , in theory any way ??
this has being done by other UK modellers
good luck , love the model

I have a free flooding barge to tow behind my tug, if that counts.
All styrene construction with false cargo base approx 1/2" below expected waterline and covered in pea shingle, when lifting out of the water you have to allow water to drain out. The flooded volume has lots of baffling to stop the water sloshing around when underway.
I think it works well and the barge ends up very light but sinks convincingly.
Title: Re: SS Ohio tanker build, Pedestal convoy.
Post by: unbuiltnautilus on October 29, 2013, 12:49:51 PM
The model has an 'in' pump and an 'out' pump. Both are mounted vertically so drain out the impellor hole when removed from the water. I have a Whale Bilge Pump I have had since 1984, its been in two models, the last one in 1997, still works to this day. Anything designed to be chucked into a bilge by a fisherman has to be bomb proof!
The model has two M6 drain plugs at one end of the model, to clear out the last stubborn vestiges of water left in the ballast tank once pumped out.
Ohio wasn't designed with the false bottom concept at first, it was suggested to me by 'John The Rigging' while working on the bow. the model now has its waterproof bottom about 30mm above the visible sides of the lower hull. This has given me equipment space for pyrotechnic attachment points as well as the fixings for the two destroyers, below the hull bottom, very handy.
The model got a dusting this weekend for an open day, construction should commence again early next year, once I get these subs out of the way ;)

hello ,
 i love the model , its a great idea , you know a lot more about it than me ,as you have done this before .
but , use those simple pumps at home ,and they aren't built to last , hence my suggestion to fit 2, 1 as a back up , this is what i though about doing on a similar model , no time yet .
after all , its going to be a very heavy model to lift out of the water , if the pumps fails .these pumps use a simple 700 mabuchi motor , w a 10 cent rubber seal , between motor and water ,and water rusts up a mabuchi motor -you can also get a pebble in the pump stator , and it wont work .
 im not that strong any more , so if it was me ,i would fit 2 pumps , thats the only reason i suggested it .
 looking forward to seeing it on the water , keep the photos coming , its a lovely model

 There is no such thing as a dead project, just a dusty one with spiders living in it!
 
 I made a foolish promise about two months ago to have Ohio in the water by our next canal run in Chichester ( Easter Bank Holiday Monday, worth a visit, even if only to get rained on! ), so i decided to evict the spiders and get back on with it.
 A problem I encountered last year revolved around a big Yuasa 12v battery purchased for the model, at 10amps, the battery is physically taller than the standard 7amp gels we are all used to, and wouldn't fit past the motor! Being one of my builds, the motor was well in there, and refused to budge. even after mallets and chisels and claw hammers. Fortunately graham the mechanic was there. Out came the motor mount, creaking and cracking as the hull let it go. then I discovered that muggins here had screwed the mount in. As indicated by the two sheared off screws left hanging out of the hull sides!
 Still, mount removed, trimmed and re-fitted further aft...progress.

Next job, battery tray. This was made using a mix of 1/2" and 1/4" ply, wrapping around the base of the battery. the reason for the use of thinner 1/4" ply, sticking out of the bottom of the hull is the bolt head, connected to a bolt projecting under the hull. This and others are there in case I have to sling any extra lead under the hull during sea trials...and they are in the way.

Post by: unbuiltnautilus on March 18, 2014, 05:37:46 PM
One of the Display Teams rules regarding Pyrotechnic boats is that the main battery must be secure and unable to move about. Prevents the model taking on an unexpected list or worse during a display. To that end, I needed to fit some sort of strap. Normally velcro will suffice, however with the depth of the battery, I decided to fit a top strap. A bit of offcut mahogany ply from the real boatbuilders next door to the clubhouse was 'appropriated' from their bin and put to good use. Drilled and tapped to take an M4 stud, these would then be fitted to the hull sides with epoxy.

Final job being to mount a suitable clear acrylic tray above the motor, to mount RC equipment on. For this job I used the Best quality B&Q plywood ( delaminating a speciality!) for more supports, treated in a similar way to the previous battery clamp supports, drilled M4 and epoxied in place.

With an acrylic tray in place, I can start the RC installation, hopefully for the April run.

Next jobs, seal the timbers, a good splash of polyester resin everywhere sorted that out.
And time to bolt on some detail. I have added two cargo hatches aft. These straddle the removable hatch, good bit of forward planning there! So they are attached to the hatch via cyano and 8BA Nuts, bolts and washers.

Next job is to bring the stern section slowly to life. Propshaft and rudder removed for greasing, followed by making up a loom for the motor. This was then spun up for the first time, adjusting the tension on the motor mounting clamp until it ran sweet. The photos show my trusty SM Services Servo Tester testing the steering servo. I cannot begin to say how useful this piece of kit has been over the years. Bought it at Sandown Park at least one year before that show ceased to be.

Gunfire sound effect speaker next. I could not make head nor tail of the Maplins Amplifier and almost poped my precious gunfire sound unit. So i have decided to make the stern section of the boat into a giant speaker box. I have fitted a mylar speaker due to its splash proofness, as opposed to a better, gruntier one ( I have also run out of depth for a deeper speaker, on a model 100" long, run out of room, who would have guessed it :embarrassed: ).
Next was a sheet of 1.5mm Epoxy glass, epoxied onto the acrylic hatch to provide some sort of heat proofing for the smoke unit, stop it melting through into the boat!

Some balsa wood carley floats have now been added to the model, with blu tac no less.

Bringing the build up to date is my first attempt at moulding fittings. The model being built to the faintly ridiculous scale of 1:61 and a bit, will prove a challenge for some fittings. So I have started with doors, one open, one closed. I am using a re-usable hot melt rubber, requiring me to avoid any plastic components in the masters. My doors were a combination of etched brass bits, mirror glass rectangles, bits of brass rod and copper shim. At the same time I had a go at the oil tank vent hatches, needing about fifteen of these, moulding seemed to be the way to go. 1.5mm ply, capped with suitably detailed litho plate and topped off with a bit of 00 gauge rail track.
The red moulding compound went straight in the microwave ( dont cook in it, dont worry! ), heated up, then poured into a little baking tray, with my fittings glued to the bottom. then left to dry.

Out with the two mix resin, 50:50 ratios for us stupid people :-)) .
I picked up a trick reading one of them Merriman Submarine sites recently, regarding the moulding. He was making sacrificial annodes en masse, in plasticine. Pouring the resin, then floating a grease proof paper over the liquid. Capillary action drawing it down on the plasticine, and providing the mimimum of cleanup once the items were released. who said nothing good ever came out of the US of A! SS Ohio did...
Anyway, didn't have any greaseproof paper, did have some non-stick plastic box material.

On the above photos, the group of two oval tank hatches in the red rubber mould, have a little round hatch in the middle. This turned out to be plastic and partly melted in the hot rubber, I just poured resin in it in the hope it would be okay..it wasn't.
Final job this last weekend, Oval tank vents, on a stick.
These were built up from a mahogany square core and two halfs of a bit of ramin dowel, cut in half, badly, on a band saw. Glued together, sanded till they were right, then cut off using the guide on the bandsaw to get them uniform. Boiled sweets made of wood, numbering fifteen.

Not sure epoxy is the right material for heat proofing, as it softens when heated and looses its strength.

Having been in this hobby for more years than I dare to remember, I find I am allowed, no entitled, to forget most stuff that I have learnt over the years...so yes, fibreglass sheet is a hopeless insulator, I just forgot. Starting again....

The Fibreglass sheet is an 'underfelt' for my main heatproofing material which will be ----------.

Oh, and I "xxxxx" up the moulds last night. Left the resin in not the required 30 minutes, but 9 hours. would not release, ruined. The good news is It can be re-melted. I now have two new, moulds, not ruined, thank you.

It floats. It didn't leak. Draws 5 Amps at full speed ( just made it up and back on one 10 amp battery ). Slightly light in the bows ( fix that this Sunday ). Turns in about a 10 foot circle, not bad for a 100" model. Bit slow, but that was mostly me taking pictures and enjoying the handling of the model, its probably a good regatta boat, I was playing in the lily pads with it!
Now I have to paint a Panzer IV for someone, and finish off Nautilus ( cos I'm selling it...tell no-one!), so Ohio work will now slow down again. At least it works though :-)

In order to get the bows down to waterline (and below) just use the original cargo.

This is available not too far from Fawley Refinery by way of a pipeline, recently judiciously tapped.

 Scooby Doo back to Sunday moment ~  :o ~  :o ~  :o ~  :o ~  :o ~  :o ~  :o ~
 
 Before the maiden voyage at the canal, I spent sunday securing the various fittings to the model. this entailed scaling up by 1.4 all the dimensions on the plan. lots of pencil marks, followed by precision sticking with either epoxy or super Superglue.
 The fittings were pencilled round first. The decks then abraded with a hobby drill to provide a key. The bollards were drilled to fit and epoxied, while the home made tank vents were cyano'ed down without the use of an activator. Giving the glue more time to penetrate the timbers before hardening.
 Some of the vents are the correct spacing between each other, but have had to be shifted aft to avoid the metal pyro trays already fitted. so they look right but aint in the right spot!
 The 80mm Graupner 4 blade prop, bought for another job, was drilled through and tapped through, then an M5 bolt run through the deck from below and the two mated together.
 
 Scooby Doo back to last week~ :o ~  etc...
 The stern section has had its skylight windows squared up, I may have been drunk when drilling the holes originally, probably not though, just rushing the job. 32 Billing portholes later, thats complete.
 Support struts drilled through the boat deck had 2mm brass washers soldered flat against the underside of the boat deck. these were then superglued in place, giving me a nice flat area to bond, as well as the vertical holes.
 Some of my cast doors were fitted. I am having issues with this hot melt moulding material, having lost about five moulds so far, when the resin bonded to the hot melt rubber and would not let go. Not too major an issue as I can always re-melt the rubber material and start again, but a bit of a puzzle.

Three years and one month since its last dunking in the test tank. Notice the deliberate mistake though? I forgot the diverter pipe for the 'drain' pipe. So the water shot straight up and back through the open hatches, into the boat again.... :embarrassed: . Hence very sophisticated coffer dams being placed on deck.

It was interesting watching all the pyro trays float off as the tank filled. Need to address that!

 Klutz of the week award.
 
 I have been researching the proper colours for British Merchant Shipping during WWII. Found the following recomendations; Iron Grey for the sides, Dark Grey for the decks. i had both Humbrol 92 Iron Grey and Humbrol 67 Tank Grey. The Iron Grey needed a severe mixing to get both tins the same colour, plus a bit of thinning to get it to brush on easily. Job done.
 Went to pick up a couple of extra tins for back up..Humbrol 92 has been discontinued for about twelve years...no wonder it needed a bit of a stir!
 To the local specialist paint mixing shop then....
 Me and my hat and Ohio at Alfold on Sunday.

Coming along fine UBN. :-))

The two watertight bulkhead joins are working a treat, no sign of hogging or sagging (as they say in the trade).

Will she be "active" this season"?

Worth a look.

 There was the slightest sag when we picked her up at the bow and stern. So do I tighten the nuts another quarter turn and risk loosening the bolts or allow a little bit of flex. We did launch with strops under the mid section though. Its proper heavy, so no sneaking down Canoe Lake at 8:30am of a Sunday to have a quiet sail, cos I cannot lift her on my own!
 I doubt if she will be fully display ready this season, lots of stuff to add inside and out and underwater, plus the usual display season commitments to swallow up all that spare time. So lets say years end to be fully 'bangy and sinky!'

Post by: Yarpie on June 03, 2014, 07:21:17 PM
I know of another large model, RODNEY, that sags alarmingly when lifted by two strops into the water. (By strops, I mean large timing belts and not the individuals)! HMS RENOWN's video quite clearly shows this. (I won't include the video link on this, your thread). %)

I feel you're quite right in not over-tightening the captive bolts to eliminate any movement. As long as the transverse bulkheads are strong enough and there's no water ingress, job jobbed!! O0

Keep up the good work and many thanks for the update.

Five years in build and its just getting a coat of primer on the superstructure...is this slow?

Chichester Canal this last weekend, and as Adam at Chichester commented LAST December..." haven't you finished that yet?" So I gave her a coat of grey primer on all the exposed woodwork, etch primer in the stainless pyro trays, and a pair of magnetic hatches over the pumps. So, many greys at present.

Someone suggested it would look good when I get the helicopter fitted....spud head :}

Masts and general sticky up bits next.

I love brass almost as much as I hate photographing it so here we go.

I have spent the last two weeks on the fore and main mast, handling davits, king posts and derricks (looked that lot up, hope I got the correct terminology, I am only building it..dont need to know what I am building!!).
Ohio has two masts, six assorted king post/derrick combos and eight davits not assigned to lifeboat launching ( handling hoses etc, I believe ), and i set out to build all of them.

King posts fore deck.

Built out of 8mm dia brass tube from scrap propshaft material. An M6 brass stud is soldered into the base to allow them to be removed from the model for transport. I have re-drilled old coupling inserts and tapped them M6. These will be drilled into the deck and epoxied in place. I have used RB Models brass bits throughout the mast building. Many combinations are available. From Deans Marine.. a bit expensive, but they saved many hours of tedious work, so well worth the investment. I have also tapped into my supply of brass nuts and bolts, using M3 and 12BA, plus the previously mentioned M6 bolts. Finally some mast fittings scrounged off of an etch brass set from a Billing Boats Colin Archer.

Post by: unbuiltnautilus on November 06, 2015, 05:58:29 PM
Rear Derricks.

These I have shortened, as if you build them to match the builders drawings, they interfere with the arcs of fire of the aft Bofors and oerlikon guns. contemporary photos show them level with the tops of the gun tubs..so these are shortened.
Same build as the fore ones. Both versions have the hole in the top capped off with 6mm dia beech dowel, soaked in cyano and filed flat.

Post by: unbuiltnautilus on November 06, 2015, 06:06:32 PM
the masts were about 10mm in diameter and have the 8mm ex-propshafts as bases, with the M6 bolts once again soldered in. This then has K&S metals outer tubes soldered to them. Topped off with a large brass collet that I had knocking about, plus a large copper washer on top of that. Both masts feature a long tank vent that reaches over 3/4 way up the mast. These were made from 1/8" dia soft brass tube, pinned with small 12BA bolts into the mast then soldered in situ. The upper mast being 1/4" dia K&S tube.
Title: Re: SS Ohio tanker build, Pedestal convoy.
Post by: unbuiltnautilus on November 06, 2015, 06:14:29 PM
the fore mast also features two long derrick booms. to get the profile of these right, I have sleeved them with some suitable carbon rod, cyano glued in place. More RB models brass nick nacs were used to secure these to the mast. This time with M3 brass bolts soldered in place. At the back of this mast is a long stamped brass ladder, previously made by Robbe. This was soldered into the slots on strategically fitted 4BA brass, slotted bolts soldered into the mast. I need one more of these for the aft mast..problem is they are no longer made. Any ideas?

Post by: unbuiltnautilus on November 06, 2015, 06:17:02 PM
The lamp near the top of the mast features a bit of shaped copper which I believe I salvaged from an old mains plug, bent to shape and soldered in place. The 'lamp' is a Billing Boats Bollard, drilled and soldered in place!
Title: Re: SS Ohio tanker build, Pedestal convoy.
Post by: unbuiltnautilus on November 06, 2015, 06:21:37 PM
Davits.

these were bent to shape using an Expo tube Bender. Guaranteeing me the same shape each time..no more jam jars for me! The bases started life about thirty years ago as parts of British built servos which I acquired loads off many years ago. These were soldered into 5/32" brass tubes cut to length. Once trimmed, they were stuck in a pillar drill and drilled open to 2.5mm. The outer tube preventing the little servo bits from splitting.

So this is the result of a couple of weeks of soldering.. only got burned twice..once when the old gas torch decided to let gas out of the side as well as the tip...25 later I had a replacement..and the second time when I forgot that 'HOT' comes out the end of that blue flame, while trying to get the best angle to feed solder into the job..not bad for me :-))

Post by: unbuiltnautilus on November 06, 2015, 06:32:41 PM
I forgot the big tank vents midships. These are cowl vents on top of the king posts and were a bit of a feature. I was trying to figure out how to produce these. Plastic fittings were out of the question, as they could get singed during a display. White metal seemed the best option, however, possibly still a bit risky.
Then I came across some REALLY old fittings, including a pair of brass cowl vents.. once paint strippered, they could be soldered in place as seen in the photos.

So that's it up till now. there will be some bits to solder on to the davits etc before they are good and finished, meanwhile, now i have to start considering the maze of deck piping and what to make that out of!

The ladders are available from Cornwall Model Boats in 75mm lengths, I saw them when searching for 'brass ladders' although at 1/72nd of my build I thought the rungs were too thick as they were stamped from sheet not etched. They do have plastic ones in the same length which for my build looked better.

Post by: unbuiltnautilus on November 17, 2015, 05:38:17 PM
Masts went up Sunday. Two at a time with Devcon Plastic Welder. The knurled nature of the modified boat couplings meant I had to get them fitted in the correct orientation from the off. So the masts were tightened up then lined up correctly, fore and aft. glued both down the hole and around the knurled fitting, and lightly hammered in! Plastic Welder is a fairly fast setting adhesive, hence only two masts at a time being fitted. These then had to be lined up fore and aft and across the beams of the boat visually, with the aid of a Tri-Square and the window frames inside the clubhouse. This worked for the King Posts which are vertical to the ships waterline, not so much for the main and fore masts, which both sweep back a few degrees. This had to be done by eye using the Tri-Square again, but allowing a small gap to appear at the top of the Tri-square, of the same size, twice...

The little donut of glue that splurged out was removed once dry, using a 1/4" chisel, in a downwards motion, one side of the coupling at a time, until it let go. Makes a very good paint stripper does Plastic Welder :-))

Post by: unbuiltnautilus on November 17, 2015, 05:44:26 PM
Interestingly, the little davits, that only needed a 2mm pilot hole, did not take well to the Plastic Welder, coming loose with little encouragement...so out with the Z-Poxy, that stuck them!
It now looks a bit 'busier' as a model than it did before.

Try annealing the aluminium before bending, rub it with soap first then heat until the soap turns brown and it should be soft enough to bend easily. It will work harden when bent and some aluminium alloys will age harden when left after bending.

Excellent article. The stories attached to the Ohio and to the Pedestal convoy make for astonishing reading. However, what set me on this path was a copy of a painting by Norman Wilkinson, printed in a magazine about 25 years ago, that convinced me I would one day have to builder her.

Some work done today instead of the Chichester Canal Run, which was rained off.
I had a number of the smaller tank hatches to fit, having only recently moulded them. The plan being to epoxy them in place, after installing brass M4 bolts into the bottom. The heads acting as anchor points when gluing everything in place.
I used a marine coupling end as a temporary depth gauge, this stopped me drilling straight through the whole thing, many times!
Notice the unerring use of precision measurements to locate the centres for drilling..it's a wonder anything is straight :o
Title: Re: SS Ohio tanker build, Pedestal convoy.
Post by: unbuiltnautilus on March 05, 2017, 11:31:56 PM
I had to make a few compromises with the positioning of the tank hatches, the 'special' function trays have got in the way. So, I have less than I should have, in not quite the right positions. It's all added detail though..very happy.
I drilled part way through the 8mm ply deck, to slightly larger than the head size of the M4 bolts poking out of the bottom of the hatches. This gave me wiggle room to adjust out my poor centre drilled locators. Then I counter sunk the holes, this gave me a bit more room for epoxy plus the sawdust in the holes!

Surprisingly, I did not set out to use the coupling end for this. It is 4mm and was going on a 380 motor as an offset 'trembler' for a shaker plate, for getting rid of air bubbles while resin moulding. The whole thing being bolted to an old plastic cutting board, with rubber feet fitted for good measure...it works too. Noisy though!!
