Title: HMS Coventry build
Post by: radiojoe on May 14, 2014, 09:49:45 AM
Hi All,  I finished my third Deans build a while ago and decided on a type 42 for my next, I have been posting my builds on Deans forum but as the build section is restricted to Deans own make and they don't have a type 42 I hope you all wont mind if I post my build of HMS Coventry on here, It will be my first venture into semi scratch building of a warship, and I have no doubt it will be a long build, I plan on starting it proper about September to be a winter build, I got the 1:96 plans from Jecobin  it's actually HMS Glasgow but being both early batch 1, I thought it would be close enough, I chose Coventry as I have a relative who was one of the survivors when she was bombed. I have also ordered the hull from Sirmar and will be getting most of the fittings from Barry as well over the next few months, I say most as I have branched into moulding my own fittings and has been quite successful albeit mostly simple stuff like wt doors, lockers etc.
studying the plans I got itchy fingers and thought I'd potter about and do bits and bobs so started by making her rudders my usual laminated plasticard and sanded to profile.
I joined Mayhem about a year ago but haven't got round to posting, but have frequently visited and have picked up a lot of building tips off you guys.

Thanks Martin,
I thought I would post some pics of my fleet so far if it's of any interest,  the pilot boat is my first total scratch and the hull is over 30 years old but has gone through a few changes in that time, and is still going strong,  my first warship is Solebay , next is Bramble and then Zulu just finished and had her "sea" trials today and I am very pleased with her.  Joe

If you would like them or think they may be of use I have 54 shots Of Liverpool taken last month but taken for a builder point of view so some are of unusual angles. (Also Gloucester and Manchester)

Thanks Ray,
and thanks again to Rob for the excellent photos no matter if some are batch 3 the deck structures are mostly identical, as I'm building an early batch 1  the main difference will be the ships boats and crane davits amidships as opposed to the wing decks and hull panels/supports of the later ones, I intend to make the main superstructure and the hanger removable for access to the hull so the crane davits are going to be a bit of a problem as they are fixed to the upper and main decks, it may be that if well fixed to the upper deck they may just lift off with the bridge structure and simply rest on the main deck, anyway that is a long way off and I'm sure I'll figure it out.  {:-{ :-))

Hi ya Joe, welcome aboard
 
look forward to seeing your build.
 
I myself built HMS York a few years ago and I enjoyed the build.   I used a lot of Sirmar fittings in the construction of my model.  One of the books I used as a reference is Modern Combat Ships Series number 3, type 42, by Leo Marriott ISBN Number 0-7110-1453-1.  Whilst looking around the web I noticed books are going for 'silly money' I think I might have paid a few quid for my copy a few years back.
 
I noticed you mentioned the boats and how you are going to secure them - I had a similar problem myself which I overcame whilst I was building HMS Exeter WW2 version - this was where I made the upper deck lift off, leaving life boats secured to the main deck - have a search of this forum there are pictures of how I did mine.  To me though I was looking at the radar on the type you are building and its the 'older type' the 965 bedstead one and I notice Barry from Sirmar lists one under HMS Glamorgan and also Fleetscale do a brass etched one for about 14 and I have used a lot of Fleetscale brass etched stuff and I can vouch that its pretty good - so is Barry's of Sirmar - I am using a lot of his fittings at the current time on my revamp of HMS Norfolk type 23.

Thanks for the info guys, always appreciated, as far as know only the first 3 of batch 1 had the double bedsteads and the boat davits , Sheffield , Glasgow, and Coventry, I can't find any info on why the boats and davits were omitted on the rest.
just had a  e-mail from Barry the hull is ready and should be with me sometime next week so the project is taking shape.

They were removed because of weight and stability problems especially after the Falkland's when extra armament was required. You will probably have similar problems unless you built your model using the lightest materials possible and keeping any heavy items below the waterline.

You have missed out HMS Birmingham BTW.

My pictures of HMS Coventry fitting out and completed can be found on either Ships Nostalgia of Sea the Ships I can't remember which.

Thanks LB, had not realised Birmingham was built with double bedstead and davits I've only seen photos of her fitted out as the rest of the type I guess she must have been converted early on.

Hi there Joe
 
according to Wiki there were 6 ships in batch 1.  According to the book I have all 6 ships in batch 1 had boat davits and also the double bedspread according to the book that is what it was called.  Here's a link for you, but no doubt you will already have it.   Looking forward to seeing your build.

Cheers for your comments Frank and John always welcome, Yes I am beginning to realise that the batch 1 were built the same and later converted alas without Sheffield and Coventry, which explains why I've seen photos of Cardiff and Newcastle in both versions, personally I prefer the boat/davit version although that double bedstead could be effected by wind, but judging by my other ships of a similar size there is plenty of scope to add ballast to over come stability problems in fact it always surprises me just how much lead it takes to get them down to their waterlines, with Zulu I did add more ballast and raise her boot topping by 6mm to get satisfactory stability, John I see you are from South Shields, my fathers home town and although born in my mothers home town of Gosport the first 8 years of my life I lived in South Shields at 174 Eldon Street that address was drummed into me by mum in case I got lost, I believe the area is an industrial estate now, and although very young still recall there was a very impressive town hall building I'm guessing it's still there.  Joe.

Hi one and all
 
Have a look at the image I have just put on and this is from the book 'Modern Combat Ships 3' referred to in my previous posting - where I stated bedspread was the nickname of the aerial.  I have always referred to it myself as the double bedstead - but there you go.  Over to you .....
 
By the way Joe, your former home has now been replaced with newer buildings - I think they are work units.  Hey ho progress so they say ..... hey did you have the outside netty :-)

oh yes the town hall still stands stately / it was shot blasted a few year ago to get all the seagull dropps off - they also refurbished the ship which is on top of the clock - weather vane.   We will say nowt about the occupants of the town hall though :-)

Still waiting for the hull to arrive, not too bothered as I know Barry ( Sirmar ) has work priorities, in the mean time I have been getting bits of her running gear, Rabosech shafts and a-frames on order, and the motors / mounts and couplings came yesterday a pair of Mabuchi 555, on reflection I think these may be a bit on the large side but with an inner shaft of 330 mm. I can get them in close to the bottom of the hull going by the plan, but I'll see better when the hull arrives, on the plus side they are not too fast when run on 7.2 v and they do have plenty of grunt.

Post by: radiojoe on May 31, 2014, 07:54:46 PM
Having seen the working stabilizers earlier in the thread, it has planted the seed in the old brain, and have decided to have them working in Coventry, I'll link them to the rudder servo so they may help counter the lean out on fast turns, even if they are not that effective, the extra feature appeals to me, I'll fit them the same way as rudders,  :-)  .

Hi ya Joe - I have been playing round with one of these gadgets with a view to making it work stabilisers on the model boat and all the experiments up to date make it look pretty promising - it senses the movement and alters the position of the servo.
Have a think about one of these.

Can't find that old gyro, must have chucked it when I refurbed my dry dock, typical as soon as you throw something away, you want it, anyway my motto is don't run before you can walk, so having decided to have stabilizers working albeit limited, for this build I'll just link them to the rudder and see how effective they are  %% .

Title: Re: HMS Coventry build
Post by: John W E on June 02, 2014, 05:51:57 PM
hi ya Joe
 
The thing is really; do the stabilisers really work on our scale models.?
 
I think this is open to a big debate.   I have built a 1:48 scale Leeds Castle which does have/did have operating stabilisers.
 
It works on a different system to the gyro system - this one works on a swinging pendulum system.
 
I myself am not truly convinced that they work that well - more of a gimmick.
 
To make the stabilisers become affective - we would have to double the size of them; the best safety guard really with these types of models - as you will know from your last build of narrow warships - is to keep the weight down low - as low as possible in the hull.   The 2 type 42 warships I have built HMS Manchester/HMS York - I powered them both with a 10 amp 6 volt gel cell battery which was laid on its side a little way past midships of the hull - and also think its about a 2 ounce slug of lead placed on the same side of the hull where the terminals are on the battery.   This is to counteract the weight of the battery cos the battery is heavier at the bottom end than the top end where the terminals are and as a test of stability I was able to roll the model on its side until the water flooded onto the deck and about 1/4 inch up the main side of the superstructure & when I let go of the model it would right itself.   This way, when I knew I was in the middle of the lake I could heal the model over so that the decks were awash and it would right itself.   
 
My party piece for these models is to go full steam ahead up the lake, flicking rudders from port to starboard, thus creating a roll in the model and then when the model was healed over either on port or starboard roll keeping the rudder set at that side and watching the model squirm out of its roll  %%  had a few scary moments though, even though I knew the model would right itself.

Title: Re: HMS Coventry build
Post by: radiojoe on June 02, 2014, 07:01:47 PM
Yes John, I think you're right about the stabs, I think they will be more of a talking point at the SWA exhibitions than any use on the water, but I like the mechanics of the build so they will add a bit more interest, and as my relative who served on Coventry would say   "stabilisers? What stabilisers ".
Initial studies of the plan indicates the motors will be positioned just aft of her funnel and I'll have my usual two nmih high capacity batteries immediately forward of them which puts them just about amidships, the motors are also quite close to the aft stabilisers so the stabs shaft tubes will be close, I could extend the prop shafts if necessary.
Barry (Sirmar) has said the hull should be with me this week, so looking forward to that :-))

Joe.
Title: Re: HMS Coventry build
Post by: radiojoe on June 04, 2014, 05:08:27 PM
The hull arrived today, first impressions are it's more rigid and robust than the three warship hulls I've used previously, and as with any grp. moulding produced on a commercial scale it needs some preparation and a couple of bits of filler here and there, this was expected having worked in the boat building industry for many years, one thing I wasn't expecting was the moulded in bilge keels, very pleased with that as I thought I was going to have to make them from laminated styrene, now just the stabilisers to make, there is also a fair amount of spreading across the beam, so this will need sorting, this seems to be common in grp hulls.
So I made a start on rubbing down the flash from the mould joints, The moulded in shaft outlets will have to be cut out as my shaft tubes are a larger diameter than them, just as well I wouldn't fancy drilling a that angle anyway. ;)  >joe
Title: Re: HMS Coventry build
Post by: radiojoe on June 05, 2014, 08:53:57 PM
Today I trimmed the waist off the topsides and sanded them to a fair line along the hull, made the cradle and initially fitted the shafts. Joe.
Title: Re: HMS Coventry build
Post by: radiojoe on June 09, 2014, 05:55:56 PM
Got a bit more done the last couple of days fitting the frames, I am fitting more frames than I normally do as there was quite a lot of spread across the beam , some 20mm at the widest point. so I gradually pulled the beam in to the correct measurements at each station line and held in place with masking tape till the frames are secure, I'll fair in the top sides more when I fit the deck bearers and cross members, but she's looking fairly robust now, and I'm quite happy with the progress.  :D  Joe

Thanks Mike, well the plan is to potter about with fitting out the hull, up to deck, I've just ordered a set of fittings from Sirmar that are going to take at least two month's so the superstructures will be started around September, but as you know Mike my builds don't always go to plan  %) . Joe.

 :-)) Nice work Joe, but can not help but notice with all that wood work being inserted into that hull the floor around the table is very clean!   So you must have some other place to do the dirty work or you have a very good cleaner or Hoover! :police:
Will watch your build.   The section that you bonded in; what did you use to bond them as I have over 14 to put in my build soon.   Just brought the sheets of exterior 3 ply wood for the work.

Hi Joe,

I have just found you here and will follow your build with great interest.  :-)) :-)) :-))I also prefer wood for frames. I glue it with epoxy and after the bond has dried apply epoxy with a brush (24 h epoxy which is used for laminating).
Title: Re: HMS Coventry build
Post by: radiojoe on June 10, 2014, 03:54:23 PM
Hi Arno, good to hear from you my friend, yes it's a good idea to seal the frames and I think I will on this one after I have done all the cross members and deck bearers.

Hi Paul,  I use a scroll saw for the frames, once it's hooked up to my old Dyson you get virtually no dust at all, one of my favourite tools and at 90 was worth every penny,,  the fillet around the frame is P38. I first tack the frame in place with three spots of a two pack acrylic adhesive, it's not easy to work with as it sets hard in less than two Minuit's but is a very strong bond, then apply the P38 fillet and clean off any waste as it sets.
Title: Re: HMS Coventry build

Got the rest of the frames fitted and bonded in the shaft tubes, and faired in where they exit,  then fitted the intermediate bearings and next the tricky ones the A frame bearings, I think it turned out OK, I shaped the A frame legs as I usually do, so they don't look too bulky. Joe

Title: Re: HMS Coventry build
Post by: radiojoe on June 12, 2014, 11:38:53 PM
Hi Thanks Derek,  the tubes were aligned and bonded in before the A&P frames were fitted so the shafts held the bearing frames in place, the blue tape is just to seal round the frame legs while the epoxy is applied inside. Joe

Post by: derekwarner on June 12, 2014, 11:56:52 PM
OK.....understood Joe.......are then you just relying on the lubricity of water between the A&P [brass/bronze] frames to the stainless shafts?.......which I assume are a Grade 303 or 304 material........

 %)...so if this is the case, would you give them a shot of WD40 whilst rotating.....after each running?.........Derek

 I exhibit my boats with the Surface Warships Association, so I think the open shafts look more realistic, when I do get round to sailing them I oil the bearings before and after, up to now I have had no problems with them.  :-))

Hi Joe, thanks for the information on the Erbauer scroll saw, I found one on the web and have just purchased it in the auction.  Got it for a great price and the unit has never been used.   This will help me as I was not relishing the idea of having to use a small bow saw.  Should get it in the next few days.  Paul.

Hi Joe  the saw arrived today, still in its wrapping and has not been used.  What is the best blade to use for cutting 3 ply and what speed would you recommend.  There are what look likes small hack saw blades.
Title: Re: HMS Coventry build
Post by: radiojoe on June 18, 2014, 07:49:45 PM
Hi Paul,  I use a fairly fine tooth blade at full speed for cutting long straight lines and slow it down when I get to a corner and speed up again etc. most of the blades have little bars at each end to hook in the machine but you should have two small fittings for attaching to fret blades, the very thin blades, You can attach the blades in two directions strait on or sideways for cutting long pieces, spare blades are available from Screwfix but I've had my saw for a couple of years now and only had two blades break,  the trick is to put the right amount of tension on the blade without over doing it you'll soon get hang of it. :-))

The hull didn't have the sonar bubble, and with advise from someone who has built a couple of type 42s, about the stability of them, I am going to cheat a bit and fit two one near enough where the forward one should be and another about amidships, the combined weight is around 8 ounces, I thought 1/2 a pound slung under the keel would be more effective than above the keel, concentrating on my tug build first but I'd already started fitting the sonars and thought I'd finish them first.

While waiting for the set of plans for my tug build I thought I would fit the rudders to Coventry, I used pieces of scrap styrene between the hull and rudders and a support between the rudders to keep them parallel, taped in place till the epoxy around the tubes sets, I'll put extra support on the tubes later.

just an update,  Coventry still on hold while I build my envoy tug, but her fittings arrived today from Sirmar with just a few to follow, but not needed for a considerable time, nice set of fittings with the usual flash to clean off, the radar domes are solid so I will be hollowing these out as they are high on the structures, when you have been working on a 1:48 for a few months you sure notice how small the 1:96 fitting are %%, 
So at least the time on hold has given me the chance to get all the "KIT" together it will be a long build being scratch on a hull but it's good to know all the bits are in the drawer waiting. :-))

Yes hairy times indeed, one of the reasons I wanted to build a Type 42 is that, in my opinion, they are the last British warships that actually looked like warships and not the monolithic ones we have now, and the reason I chose HMS Coventry is that I have a relative that was on board at the time it was hit, he was one of the lucky ones who escaped with out major injuries, not sure what his thoughts will be when he see's her finished.   %%

With my envoy tug completed, I've restarted my semi scratch build of Coventry, and fitted the deck bearers, I fit these dry with clips and use a piece of deck ply to position them, I then run thin cryano in the joint, then with the hull on it's side I apply epoxy to the underside of the bearer and the hull side, I've found this way cleaner and more accurate than clipping them in place on wet epoxy, next I think I'll cut out the aft quarter deck openings, this will need to be done very carefully and should be a bit easier without the weight of all the running gear.

Cut out the quarter deck openings today, my Dremel really did earn it's keep, these openings leave very small areas of hull around them so I thought carefully drilling 2 mm. holes around the edge would be the safest method to form the opening and then using the Dremel with a 8 mm. drum sander clean up the edges all this didn't dent the Dremels battery, (I love that bit of kit), and also initially fitted the quarter deck

Post by: radiojoe on October 25, 2014, 04:33:22 PM
Having dry fitted the aft quarter deck I had to decide whether to make it and the flight deck above it removable to access the tiller flat, I felt this would be so much hassle firstly trying to hold the quarter deck in place and make it water tight, and secondly holding the section of flight deck in place with such little amount of hull around it, so have decided to fit the steering gear and make it as durable as possible and fit the quarter deck permanently, and later when fitting the main deck I'll leave the section of flight deck loose till the quarter deck is fitted out, and then bond that in place to strengthen the hull round the openings.
Started the steering gear by making the tiller arms and link and fitted to boat seem to work as intended, next I'll fit the servo to complete the steering.
Title: Re: HMS Coventry build
Post by: warspite on October 25, 2014, 04:41:22 PM

I am glad to have joined MBM as I am learning lots of new tips on making boats and ships.

Just a thought re allowing access to the steering flat but making the hull water tight, Could you build the bulkhead in front of the quarterdeck full height from bilges to upper deck with openings for the control rod and using a rubber bellows to keep water from entering the hull proper?

This provides the majority of the hull watertight. Could you then use a soft rubber seal to keep the quarter deck in place and a deep bezel to hold the stern deck in place?

Just some 'finkin' on my part :O)
Title: Re: HMS Coventry build
Post by: radiojoe on October 25, 2014, 08:55:23 PM
There is so much detail built on the quarter deck and the bulkhead, it would be just impractical to make the deck removable, one thing I personally don't like to see is un scale screw heads holding removable decks in place,

When I came to fit the motor bed I realised the length of the shafts I got put the motors right in the way of the aft stabilizers, so as there was 80 mm. of shaft forward of the bearing bosses I thought I'd move the motors aft 65 mm. this also had the effect of lowering the motors, which is not a bad thing, so now I have all the running gear installed, the motors I bought for the boat are Mabuchi 600s supposed to be 7.2 to 12 volt, but I wasn't to happy with how they ran on 7.2 v. they actually ran better on 12 v. I remembered I had a pair of Johnson 600s I acquired when I got my tug job lot, so decided to change them over, job done these Johnson's run very nicely on 7.2 volt. not sure why that is, they are all 5 pole. next I'll fit the 4 stabilizers.
Title: Re: HMS Coventry build
Post by: ballastanksian on October 28, 2014, 07:59:07 PM
Your equipment layout is very logical and tidy. I have read that some model boaters disapprove of chocolate block connectors due to the possibility of cutting through the flex with the screw. Do you have a method of using them that makes them safe and efficient, or have you always used them having found no adverse effects? I suppose if you loosen and tighten them repeatedly when using them instead of Tamiya or Deans connectors they will cause problems, but as a long term connection system this isn't a worry.

Keep up the good work Joe. Having read Bluebirds build log of HMS York, it is interesting to see the ways you and he are travelling to build your '42s'

Title: Re: HMS Coventry build
Post by: radiojoe on October 28, 2014, 10:32:30 PM
Yes I frequently use block connectors and have never had problems, the trick is to solder the tails first, the screw clamp system is not only found in block connectors some expensive distribution panels use them, and if you take the brass bit out of the block it can be used to join control rods.  :-))
Title: Re: HMS Coventry build
Post by: radiojoe on October 29, 2014, 06:01:52 PM
Made the stabilizers by laminating two pieces of 1.5mm styrene over a 3mm brass stock, the stock had the end ground to a flat that fitted in the recesses in each half of the blade, bonded together and sanded to foil profile, I decided not to use the ones from Sirmar, they would be fine for a static display, but as I'm experimenting with working stabilizers I made them a bit over scale. %)
Title: Re: HMS Coventry build
Post by: radiojoe on October 29, 2014, 07:00:06 PM
Looking ahead somewhat I've been pondering whether to use styrene or ply for the superstructures, I prefer working with ply, but have to be careful of weight, a test today was for me surprizing, I weighed a piece of 1mm styrene it was 62 grams, I cut a piece of 1/16" ply to the same dimensions and it weighed exactly the same, must admit I always thought styrene was lighter, so ply it is then.  %%

spent this afternoon fitting the stabilizers, used strips of .5mm styrene to set the clearance between hull and blade, the tubes were fitted in the hull tightly to help hold in place, and the blades held with tape at the right angle, then fitted the stiffener webs and tack in place with cryano, and the epoxy, next the control rods were made up and fitted, and all is working as I had intended. %%

Hi Derek,  I had thought of that earlier in the build, even thought I had an old gyro somewhere but must have thrown it out when I refurbed my work shop, so I decided to link them with the rudder to try and counter the roll out on turning, most likely won't do anything, but I enjoyed working it all out and making them work.

I mainly use Admiralty glues thin Cyanoacrylate professional on plastic or ply/wood, assembled dry and the cyano run into the joint the bond is instant and strong especially on wood, I guarantee you will destroy the wood before the joint, I also use plastic cement on fiddly small structures as it allows a longer assembly time, and of course epoxy 5 Minuit and 30 minute for shafts, deck etc.

Hi Derek, yes there's a lot going on in that photo,  the angle of the stabilizers pretty much matches the rudders, I think any more angle than that would probably cause too much drag, it will be interesting to see what or if any effect they will have, I can lessen the angle using the holes in the tiller arm if necessary but that's a long way off.  :-))

I did the battery holders today, I am inclined to forget this till after the deck is on and then it's more difficult to get at, and then made a start on the deck setting out the superstructure footprint, cutting and the initial fit, next I'll cut out the access hatches, the type 42's allow two quite large hatches, I tend not to make them fit the deck structures but keep them well under, just large enough to get to what ever is under them and have an upstand around them, I use blocks to locate the structures.

The simple act of putting the deck on top of the hull makes such a difference to how far a project has come. I laid the forecastle on my HMS Ready and it has brought it alive.

Title: Re: HMS Coventry build
Post by: radiojoe on November 02, 2014, 11:26:13 AM
yes I know what you mean, it kind of changes a hull into a boat.

before I get too far with the deck I have to fit the deck gun servo, so I thought I'd make up the Mk 8 to see the best way to connect it to the servo, I ended up making my own barrel, I'm not a big fan of white metal I'm sure it's fine for statics in cases but quite vulnerable when taking boats around exhibitions, the base moulding is not designed to be turning so I had to carefully cut where is turns, I got away with it without breakage so is now ready for fitting.
Title: Re: HMS Coventry build
Post by: ballastanksian on November 02, 2014, 07:20:30 PM
White metal shrinks and pressure on the mould will cause the parts cast to become thinner therefore what began in scale becomes out of scale assuming the part was designed in scale to begin with.

Over the years I have found many drawings to be far from correct in the base dimentions. I am currently designing a Whippet tank for a company in 1:72nd scale. The plans I have are noted as 1:48th scale but come out as 1:55th, a country mile out! Not only that but the widths and lengths of each view are not the same so I had to work out scaling formulas for each view so that the parts are accurate.

There are lots of pitfalls in the process of modelmaking. the difference in size between the casting and your brass barrel shows how different people interpret a piece and how parts end up.

Nice piece of brass Joe!

Title: Re: HMS Coventry build
Post by: radiojoe on November 03, 2014, 05:20:46 PM
Fitted the deck gun servo, on my other boats with turning turrets the turrets have been large enough to bond a round servo horn on the under side and mount directly on the servo post protruding though the deck, this Mk 8 auto gun is a lot smaller and I wanted to use the base that I cut in two pieces so I fitted a piece of treaded rod in the servo post locked with epoxy this protrudes though the deck and the base, I drilled a 5mm hole in the bottom of the turret and bonded in a piece of fuel tube this is pushed on the rod and is gripped quite firmly, A trial proved it works well enough, also on my others I've fitted a P96 to expand and slow the movement, I will fit one on this boat to increase movement but as the MK 8 is a fast training gun I'll leave the servo speed as is , also cut out the access hatches.

I tackled a very fiddly bit I wasn't looking forward to, the rims around the quarter deck openings, made more tricky by the early batches round transom, I think I got away with it, by the time it's blended in with paint, before this I boned in the quarter deck, next I think the main deck can be bonded on leaving the flight deck off till I do the detailing below it.

On all my boats I like to have the RC switch on the deck somewhere disguised as a deck fitting, luckily I remembered this just before I bonded the deck on, the switch fitted to the ESC is too tiny to do anything with so I adapted a mini switch to make it operate though the deck, I'll fit a vent or something to it later the first one I did has a ammo box that slides for on and off, the other two have vents that pull up for on.

Go another bit done today that I wasn't looking forward to, the bridge wall, the combined camber and curve plus the wrap a round ends make the piece a really odd shape when flat, but after a bit of trial and error "mostly error" I managed to get it done I decided to leave the nav light openings till I made and fitted the inner boxes this proved to be a wise move as it made cutting out the openings a lot easier with the corners strengthened by the boxes, next comes the real tricky bit the bridge house with all those lean out windows.  %% %%

Post by: ballastanksian on November 21, 2014, 07:26:25 PM
Previous experience shows that curving plastic with such cut outs, or similar drastic reductions in material can cause a fracture when bending or unpredictable behavior when bending plastic hot. So your idea to cut after is most wise.

Lovely look to that bridge, definitly inspiring Joe.

Post by: radiojoe on November 23, 2014, 11:05:53 AM
Thanks for the encouraging comments,  the next step seemed to be the main bridge with all those windows that I thought was also a bit daunting, but I dived in and got there in the end after constantly reminding myself to take my time as one slip with the scalpel would ruin a set of windows especially if it was the last window of a panel, to get the lean out I first tried scoring the panel but this tended to break with too much handling so I tried holding the panel under a steel rule and just bending along the line this seemed to work well, I used .5mm styrene for the two sides and the front mainly so the windows openings don't look too thick anyway I was quite pleased with the result, also did a bit of detailing to the hangar. :o

More progress with the bridge structure and pre fitted the wheelhouse roof, this will be left off till the priming is done and the windows glazed, next I'll do the Olympus air intakes and funnel deck, the funnel has still not come from Sirmar, and I need it now to see how it fits in with the structure, the fittings were ordered in July and the fittings came in September minus the funnel that Barry said would follow, I know he only dose it part time but I think I have been more than patient, I've e-mailed and had no replies, so I have decided to put Sirmar down to experience and make my own funnel, regrettably I will not be using Sirmar again, scratch building the funnel was not as difficult as I had thought and was very gratifying the plus side is it only weighs 40 grams a resin one would have been a heavy lump, I still have the capping piece to do  :}
Title: Re: HMS Coventry build
Post by: ballastanksian on November 26, 2014, 09:40:45 AM
I take my hat off to you Joe for tackling a difficult shape. I can see why it is offered as a solid resin piece, though I have seen some good methods to lighten resin castings using silicone plugs.

It is sad about your issues with Sirmar. As you say he does it part time, but one return message would at least have let you know of any problems he might have at his end outside of administering the range.

Re the cap, I have used a styrofoam blank covered with milliput or car body filler before now to create a light solid. Once was a railway carriage roof and the other was a space ship hull! I dissolved the foam from within once complete but you could leave it in as extra surface to glue onto.

Happy Boating, Ian:O)

The funnel looks good Joe. I intend to make my own for HMS Woodpecker. The funnels I got from Sirmar for my V+W destroyer were both more or less solid resin, took me ages to hollow them out. I'm enjoying the build. Cheers Joe :-))

You can get hollow 1/96 909 radomes from Fleetscale, if you don't fancy hollowing your resin ones out. I have a pair and they are very light.

They also have a funnel, but it is for Sheffield.

Here is the Sirmar funnel. It was partially hollow and I've removed a lot of resin (easy but messy) it now weighs 234gms. I have test floated the hull with most of the superstructure and fittings and it is quite stable even in turns. My progress is static compared to Joe's but I'm getting there.
Title: Re: HMS Coventry build
Post by: ballastanksian on November 26, 2014, 01:03:26 PM
It is a crisp casting. I see no air bubbles or blemishes so top marks to Sirmar for that. Some of the stuff wargamers and military modellers have had to put up with over the years has to be seen to be believed.
Title: Re: HMS Coventry build
Post by: radiojoe on November 26, 2014, 04:19:56 PM
Thanks for all info guys, the Sirmar funnel does indeed look fine but I've waited nearly 5 months I think that's it for me, I wasn't entirely happy with my funnel as it was,  I'd used .5 styrene to sheath it and the skin was I bit flexible so I thought I'd add another .5 skin now it is a lot stronger and also gave me the opportunity to cut out the vents before I bonded it on, it gives a recessed look to them that I prefer to mounting them on the surface.
I added the capping and I am now happy with it, and it still only weighs 55 grams,
I had seen the Fleetscale domes but didn't realise they were hollow, knowing I could always get them if my hollowing out of the ones I've got failed, I had a go at one it started out at 62 grams after hollowing out it is now just 22 grams which I think is acceptable if I don't screw the other one up I will use them.  ok2

When I made the second level of the bridge deck I forgot to cut out the transition passage before I bonded it down so I had to cut it out insitu it's a bit higher that it should be as I had fitted a base in the structure, I've used some modellers licence and put some steps to them, I remembered the transition passage at the base of the funnel so did this as I made the structure, next I'll make the Olympus air intakes before I permanently fit the funnel deck.  ;)

Hi John, when the hull arrived I thought it had come from an old mould, as there was some areas of making good to do mainly port stem and transom, but will be fine when painted, apart from that all is well.  :-))

Title: Re: HMS Coventry build
Post by: radiojoe on December 08, 2014, 03:03:38 PM
The Olympus air intakes are well on the way now, dry fitted to the funnel/deck assembly, although there was quite a few grilles of differing sizes in the fittings from Sirmar, there was only 4 of the size needed for the intake structure that requires 24, so I've made some of my own hence the different colour resin, I think for my next build which will most likely be a scratch build on a hull I'll make all or most of the fittings my self, I tend to fill my moulds carefully so as not to leave so much waste resin to sand off, unlike commercial resin fittings that are inclined to over fill and leave more resin to sand off than is in the fitting, %% %% %)

Thats one big air cleaner, I bet Halfords do not carry those!

Have you given any thought to your next project yet or are you being untra disciplined? I have reference material for my third project so I can do a better job on the hull though I do not plan to start it until well into next year or even 2016.

Looking very nice Joe, she is definitly starting to come together.

Thanks Ian, I tend to concentrate on one build at a time, which is why I shelved this build to build the Envoy class tug that was a bit of a windfall,  haven't thought too much about my next build as yet as this one is taking up much of my thoughts, being my first total scratch build on a hull, but a RFA like Blue Rover looks appealing, who knows, maybe.  %%

If you feel the urge, then a few minutes spent on the web looking at the RFA and taking some vital stats will give you a rough ball park for costs and materials without you committing to buying plans or timber:O)

I have become a bit addicted to buying plans for ships that I may never build or probably won't get around to for a decade. I have a few of them left in me:O)

 I've looked at a few RFA's including Orange Leaf that I often saw moored up on the end of the oil pier near to Gosport, just an idea at the moment,
The 42's have some tricky structures on them that I think adds to the satisfaction when you manage to scratch build it, I tackled the fwd mast today, and it came out reasonably well, I'm going to make the aft mast next so was studying it on he plan when I noticed I had made a mistake with the funnel deck, I made it too long as it only butts up to the mast and not under it, thankfully this was quite easy to put right,  %%

Added a bit of detail to the fore mast and bonded it in place along with the air intakes and funnel assembly, and then made the aft mast, and dry fitted it, next I'll make up the 965 radar housing and the aft radar dome housing plus the scot dome wings, that will complete the basic superstructure, I'll most likely do a bit of basic detailing then before spray priming.

Thanks guys, Paul the ply is 1.5mm. I've used it for the main deck and all the horizontal surfaces and styrene on most of the vertical surfaces, I've found the ply is self supporting without the need for internal stiffeners on the upper decks.

Made up the 965 radar base and did some detailing on it before bonding it in place, it has a brass tube though the centre and into the superstructure to take the shaft for the double bedstead radar that will be a working one, next step will be the scot dome wings. ;)

Title: Re: HMS Coventry build
Post by: ballastanksian on December 20, 2014, 10:10:45 PM
If you haven't done it before, stir all your rubber and resins carefully and likewise pour them carefully.

Re masters, I reccomend making any round detail like conduit with a flat edge like a stair bannister so that there is more surface area for the resin to get through and into the impression, and always make sure you seal any grilles created with etched brass or copper weave mesh as rubber loves to get underneath causing such fun as areas of bald grille:OC

I apologise if you have been moulding and casting your oiwn bits for years Joe, but it can be a demoralising experience. I know when I first tried it!

What resin are you using ? Polyester is the devil's work as it is brittle and smells. It can also leave a sticky residue on the surface that may not take paint, or causes blemishes in the paint. Polyurethane is better as are some of the newer resins that I cannot recall the name of but do start with Poly!
Title: Re: HMS Coventry build
Post by: radiojoe on December 20, 2014, 10:58:24 PM
I use fast cast Polyurethane resin and condensation cure silicon rubber, very easy to use no residue and no problem with painting, some of the fittings are quite small so any left over resin is used up in some of my other moulds and have now built up a good collection of various fittings.   :-))

I get my supplies from www.easycomposits.co.uk an excellent company in Staffordshire with a quick turn round on orders,  and given the cost of scale fittings the cost of moulding components is more than justified, but have to say I do it because I find it a very enjoyable addition to our hobby and with a bit of imagination it's surprizing what you can make. %%

Hi Doug, I recommend getting fast cast resin part A & B 1 kilo size and the half kilo size CS2 condensation cure silicon, this is all you need to get started, you can buy the starter kit but to be honest you are buying things you probably already have like brushes, mixing sticks, mixing pots etc. I use yogurt pots etc. Try making a simple w/t door out of styrene glued in a "box" as previous photo and carefully fill with silicon, well you get the idea,

The various hatches for the breakwaters came out OK, I never take this for granted, even if you have done everything right you can still get the odd rouge air bubble that really shows up on a tiny hatch, with them all in place I think it was worth all the effort, also made up the missile launcher and with that and the deck gun in place the foredeck is starting to look like a 42's  :-)

Gradually getting back into the build, can't believe Christmas has come and gone, I find after a break from the build it takes me a few hours to regain my mind set, if that makes sense, started by fitting the aft life raft canisters and mountings, and then had a go at the pair of Skynet aerials or at least my version of them, should look ok, as the saying goes paint covers a multitude of sins, this was the first time I have used solder paste, I expect you guys have been using it for years, I never realised how easy it is to use, I'll sure use it from now on. :-))

Post by: DavieTait on January 06, 2015, 05:26:31 PM
Something I learned from one of the US websites for moulding was to get a pressure cooker , take off the relief valve on the lid , connect up a HP line to a compressor with a valve in the line to close ( and to release the pressure inside the pot )

Make sure your moulds fit into the pot , pour the cast , place into the pot , seal and put 3 bar pressure in and leave for a few hours to set this compresses any air bubbles and once the mould sets thats it sorted.

Keep it up - you're doing great :-))

Many thanks Ray, yes I usually pencil in the detail using a photo as a reference so I don't have to keep looking at the photo, the detail stands out a bit too much at the moment but should be alright after a couple of coats of paint.  %%

And also a good idea, as you can get the dimentions of the parts you wish to place as you mark out. Then you can use these to make the parts if you have to scratch build them.

Another busy area is the recess in forward end of the hanger again using a photo of this area as more of an inspiration than actually copying it, still a lot of detailing to do that is the bit I think I enjoy the most. O0

Amazing watching it come together. A real masterclass.

One question Jo, you don't seem to have sealed the ply in the main structure. Will not the primer bring out the grain? This is the fear that keeps me using plasticard for my structures.
Title: Re: HMS Coventry build
Post by: radiojoe on January 12, 2015, 04:49:31 PM
The ply I'm using is very high quality with a fine grain, I've never had a problem with painting it, it's already had a rub down with 400 grit paper, I spray prime it and leave it about an hour and check if there are any grain issues, then it gets a second coat of primer, the trick is to take your time when spaying light coats so as not to get it too wet, the top coat is hand brushed acrylic.

I think we would be a bit prudish if we criticised your work in this area as it is still well detailed and once painted will look the part. I cannot claim to know much at all about type 42s except for what they did and the general shape.

Some of the detailing although enjoyable can be quite tedious like cutting the 10 pairs of brackets out of .5 styrene for the fwd life raft canisters, having already done 8 pairs for the aft ones, and then lining them up and gluing them in place, I think one side is enough for today. %% %%

I have just realised the quality of the carpentary going on there seeing those dovetails along the superstructure side/deck! I bet that took some careful marking out. Are you using cyano acrylate or epocy to stick plastic to the ply? I apologise beforehand for asking a repeat question.

I use Admiralty Glues Professional thin cyano for the majority of the build it's about twice the price of standard cyano  but it's worth it, and  I use the usual poly cement for small styrene structures as it gives more time to get the joint aligned.

Thanks for that Frank you can never have too many photos, at least I put the w/t door in the right place and had planned, after painting, to put a ladder where the one is in the photo :-))

There are a lot of things in photos that Coventry never had fitted, like the platform on the front of the radar base, I have a photo of Coventry leaving Portsmouth shortly before her deployment to the Falklands I use this as my main reference, I'm trying not to fit items that she wouldn't have had that have been fitted to the 42s refits since the Falklands.

Hi Joe,

Just spent a very pleasant evening going through your build . . . I must say your doing a cracking job!

I love the way you use a blend of materials to get a practical solution to whatever problem you encounter. Your scratch building is excellent and I admire the neat and tidy finish you achieve as you go along.

I recently discovered the joys of solder paste and although its not cheap, a little goes a long way. Do you have the self clean version?
Makes you wonder how we managed before especially on fine detail.

Will be follow the rest of your build with interest

With the basic superstructure done I thought it was time to do a second waterline test, she sat just above her waterline, level and no list, and with no trimming ballast needed at this time, with no significant weight to be added an inclination test by pulling the top of the mast sideways proved satisfactory and it quickly resumed it's upright position, so the two lead "sonar pods" slung under her keel seem to have the desired effect, I may even raise the waterline slightly as she has plenty of freeboard even at the stern. and a little more ballast in the bilges may be beneficial.
Also been experimenting with the moulding a bit and adapted my original life raft canister that had a moulded in base, to now have a separate base giving me a few more options for positioning them.

There are a few side mounted aerial bases on the boat so as with similar fittings I make one and cast the rest, mixing very small quantities of resin for say an aerial base is quite difficult so I mix still a small amount and have several moulds of various items ready for any surplus resin, this has enabled me to build up quite a collection of fittings that are useful for future models, I'm sure some of you that do moulding are saying so what's new, but my remarks are aimed at new modellers who are just getting into our fascinating hobby  O0

I've been doing moulding for around a year now but I'm certainly no master at it, and I'd recommend having a go at it, it's a fascinating and rewarding extention to our hobby, and actually not that difficult especially with basic items like w/t doors, ammunition boxes, vents etc. that you tend to need multiples of on a model, you can put all your effort in to making one really good prototype take a mould of it and you have an endless supple, and once you get into it you can experiment with other fittings,  not sure whether it's cost effective or not but the resin goes a long way and given the cost of commercial fittings I'm guessing it probably is, but that's not why I do it, I get a lot of enjoyment out of scratch building boats and seeing my own fittings on them just adds that bit extra. :-))

What ever you do do not buy your silicone rubber from Hobbycraft because the 250ml tin costs five times what a kilo tin costs from Alec Tiranti or other companies who specialise in mould making materials. 

You might find that this is too much material especially if, after trying to mould and cast, it isn't an activity for you, but you can sell it on to a fellow boater or friend who wants to try it out.

The shelf life isn't infinite, but my gallon tin is still going strong after four years. Just don't lose the tin/bottle of catylist:O)

Ironically, Hobbycraft's PVA (Red bottle) is excellent and quite good value. It beats many non water proof PVAs out there and I have used it for many projects throughout the last five years. While of little use on models that can get damp, for static models it will be of great use.

I like this part of the build, just pottering around adding bits of detail after studying the photos, some items you can only see a part of, so I use a bit of intuition and do what looks right to me, the hand rails are just .5mm styrene rod, at 1:96 I tend to have them rather understated and just an indication of a handrail, also did the RAS hose stowage and bits on the air cleaner deck, the hoses will be made permanent later.

Thanks again for your encouraging comments guys,
I got some brass etch gravity davits a couple of months ago from Scale Warship, they are actually for a County Class but were the closest I could find to the ones on the Type 42s so I thought it was time I made one up to see if they could be made to fit and look right, first I made up a mock up of the deck profile where the davits are sited this made setting up easier without the rest of the superstructure in the way, the davit have to be only fitted to the superstructure as this lifts off, so I needed to improvise a second support inboard, the davit is assembled using thin cyano but I used solder paste at the top of the support it only needed a flash of heat so didn't affect the glue, when the pair are in place I'll fit a rod between them to give extra support, one down three to go, I'm quite happy they will look OK. %%

Very tidy build. Have you sealed the plywood before painting? I only ask as with all the fine detail now on the model, any sanding of the ply surfaces to get a good smooth finish could be a bit of a job.
Title: Re: HMS Coventry build
Post by: radiojoe on February 10, 2015, 02:30:46 PM
All the ply used was rubbed down to 400 grit to get a reasonably smooth finish, I haven't used sealers for years, having had problems in the past with paint that has reacted with the sealer, so as I build working warships I'm not looking for a beautiful finish, so I spray prime and then the top coat either sprayed or brushed,  all I'm looking for is a finish befitting a warship that in real life would have probably been hand painted, maybe some parts even at sea %%

Joe.. Just a quick question: when you spray the primer and top coats how do you prevent the railings from gaining lots of drips? I'm nearly at the stage with my own build but I'm not sure weather to leave the railings and dip paint them last or if I can build them and spray as part of the main build?


Great work on the detail!

Title: Re: HMS Coventry build

Avoid over spraying, take time and apply lots of very light coats, allowing to almost dry between them, I have left the railings to last on some builds and hand painted them but it's a real pain.  %%
Title: Re: HMS Coventry build
Post by: radiojoe on February 16, 2015, 10:16:31 AM
And a bit more done on the railings, it's fair to say that the combination railings do need a degree of modellers licence especially on corners and stanchion positioning but for me it's a trade off between what looks reasonable and durability, I'm going to leave the railings around the main deck till I've painted the hull under the water line to avoid damage to the railings when the hull is resting upside down.  ok2

Tried a bit of painting yesterday with primer and today with top coat on the davits and a test piece of railing while it came out ok I think it's still too cold in the garage for any painting of large areas,

Did the tricky railings at the mast top and joined them with solder paste, wonderful stuff, tiny joints and no distortion,
I realised I had under estimated the amount of railings required, so have ordered some more sheets from Deans, I like theirs it's a bit thicker than some and quite springy, also got a sheet of flight deck netting from Scale Warships, It's a good job I don't keep a check of the cost of all the stuff I buy bit by bit that goes into any boat, at my age the shock wouldn't be good for me  %% %% {-)

We had a girl playing with a toy boat this morning on our lake and it wasn't that fast but she was having fun! I appreciate that the boys like all out and that a tug isn't a speed demon, but if in a lake full of other boats you do not want a child fresh to RC bouncing your MTB or cabin cruiser off of everyone else's boat.

No matter how child positive a club is, the members patience wears thin if they have to spend all the following week putting right the dents caused by full on daredevilness!

On a positive note, it amazes me how professional the junior powerboat racers can be considering the power of their machines, that at least is a positive thing.

Re your Springer Joe, I reckon everyone should have a tug. I am a died in the wool warship chap, but I still have two tugs on the go. They are good for steering competitions as well as rescue and just bimbling about the lake while the Coventry dries off.

As Martin said back to Coventry, I let the bottom cure for a couple of days and now she's back in her cradle, and today I fitted the port side railings, when I fitted the fairleads I used a bit of modelers licence and tweaked their positions slightly so they came between the stanchions, it seems to have worked out ok, I'll do the stbrd railings tomorrow.

On the flight deck of the 42s there is a large "grille" about 7 foot dia I wanted to replicate it somehow, I searched my workshop for something that would do the job but couldn't find anything suitable, I thought about drawing a circle and drilling all the holes but didn't fancy my chances doing that and being ply the grain could easily ruin it, so then thought I would just paint to represent it, and left it at that, yesterday while out with the dog I saw a round object about 2"dia.  in the field partially covered in mud, on picking it up I could see it was what was left of an old earphone what really court my eye was the metal grille cover so into a poop bag and home it went, washed it off and dismantled it, the grille was just what I wanted, cut out the hole in the flight deck and let it in flush, The lord will provide as the saying goes %% %%

I made a companionway for the quarterdeck , I remembered what it looked like from when I did some work on Glasgow in the junior ratings mess and the quarterdeck was the quickest root, also made the Scot dome catwalks, fiddly little things and have to admit I took some liberties with the shape to best fit the railings, these will be painted before final fitting.

Now managed to get the hull primed and the whole thing top coated, and started glazing the bridge windows before I fit the roof permanently, next I'll hand paint the decks and the quarterdeck in a charcoal grey, then I can fit the flight deck permanently,  I'm leaving the boot topping till I get the rest of the detailing, fittings, etc. done then I'll give her one more test in the domestic wet dock just in case I need to adjust its position.

As the coats have been prepped pre and post application, they should fend off all but the most violent bashes and scrapes. Varnish in my experience is as deep a topic as 'what is the correct colour of Olive Drab?' especially when talking matt varnish! Some swear by Humbrol 49, some by testors, some by DIY brands etc etc etc.

not wishing to be critical but the helicopter grid in the flight deck has a "frying pan" underneath it with a drain attached so that the water on the flight deck does not go on to the quarter deck also so that any fuel spill is contained on the flight deck not onto the quarter deck. nice build looks really good

What Greyman says dose make sense so I've done a bit more detailing to the underside of the flight deck, added a few beams and my version of the bear trap drain, when I went on board Glasgow in 2000 ish  at that time I wasn't looking at her with a model makers eye, so can only remember some things like the companionway I went down, w/t doors etc. if I knew then I would be making a model of a 42 I would have made dam sure of having a camera with me.  O0

I had to laugh at the complexity of that radar array and the fact that 1, it is available in etch brass (it is so complex 8) ) and 2, you have assembled it without any warpage or blobs of solder evident.

That is a star elementy of your build so far Joe, now just be careful. Is it more sturdy than it looks, or infact more fragile?

Amazing work as is the spiral staircase and shield.

Thanks guys, the AKE2 is made up with 40 pieces of fine etched brass, the two main elements were built using Cyrano and were then assembled with brass strips and the shaft added using solder paste, by it's nature it is quite fragile, I think even spray painting it will add a bit more strength to the many joints. %% not something I'd want to make every day, but impressive etchings from Scale Warship. :-))

That was a good result Joe! I would have thought the radar would ave weighed more but still, its good that it doesn't as it saves you having to make a clunky mount for it. The AK3 definitly adds some extra finesse to your model. Now that we have a scale weight formula, I am going to look up the formula for scaling speed.

Hi Ian,  the drive wheel on the radar shaft is 20mm dia. made from styrene discs laminated together and fitted with a rubber "tyre" and is driven directly off the splined spigot of the servo which is 5mm dia.  Giving slow steady revolutions of aprox 10 rpm. Which looks about right to me. I'd like to say it was all worked out scientifically, but in fact I've already done a single 965 on my HMS Zulu and that was all worked out by trial and error.  %% %% %)

If not, then sleep on it for a bit and feel your waters to divine wether you should or not. You have spent long enough in the trade to know which is the better way to get from one deck to another:O)

Thanks for the information about your radar drive unit Joe. I like the idea of using a rubber ring as you have reduced the damage potential to your radar array if it gets caught on something, then hopefully the drive will slip. If you had used cog to cog, it would have wound itsself free destroying your gorgeous brasswork.

I've been giving the companionways some thought and going though all the photos I used to build Coventry, there were companionways fitted in some places, but I'm thinking these were retrofitted most likely to satisfy the latterday Heath and Safety requirements, but I doubt they were fitted in Coventry's time, so I'll be fitting vertical ladders as I've tried to follow the photos and keep her as was, with just a few minor modellers licence liberties. %) %%

What a great picture Dave....thankyou for posting it. There do not seem to be a whole lot of pictures of Glasgow during/after her Service in the South Atlantic.
This one, as you will no doubt obviously be aware, (explaination for those who don't) is of her return to the UK. The exit hole created by the 1,000lb bomb can be clearly seen on the ship's side below the Mainmast. This bomb entered from the Starboard side, and carved a path of destruction through the aft end of the AER (After Engine-Room) before punching through the Port side without exploding.
Had it detonated, the effects would have been catastrophic, given that the compartment contains not only the two Tyne Gas Turbines, but also the Main Propulsion Gearboxes, first lengths of shafting, associated Lube Oil Pumps, Hydraulic Oil Pumps for the Controllable Pitch Propellors etc etc. The aft bulkhead would almost certainly of been breached also, allowing the flooding to take hold in two of the four largest compartments in the vessel. There is a very strong possibility that as with Coventry, she would have been lost.
As it was, the crew had a massive damage control job on, but through their outstanding efforts Glasgow, survived. I did read somewhere that there was a Watchkeeper standing between the two Tyne Engine modules (literally about 10 feet from it's route) as the bomb came through, he would of had a War Story to tell.

have hairy bits which look 'orrid.  I think it was from someone like Modelling Timbers. but if you have to use
Hairy thread it looks far better if you run it through hard wax.
The other thing is if you haven't done your helicopter deck netting I have some mosquito netting which I

Hi Geoff,  Thanks for your kind offer but I've done the flight deck netting with fine brass etch, not very authentic but it looks reasonable.

I think that unless you regularly solder, or do it as part of your job, solder paste and paint will be more cost effective in the long run as wastage should be minimal.

The benefit as you say, seems to be that you can solder parts while fitted to the model, so this saves even more in time, which is a valuable asset if you are expected to do your share of the housework, or garden drudgery!

As you say Ian although the paste is expensive it is in fact very economical in use with only tiny amounts needed on the sort of joints we use on our models, I've been doing some more today, also made a start on the yardarms but run out of the 0.50 brass rod for the yardarm braces. ;)

Post by: Bob K on April 03, 2015, 05:43:30 PM
Looking really incredible Joe.  Lovely fine detail work  :-))

For me solder paste is invaluable for this kind of intricate brass-work.  The cost is minimal but the additional degree of control you evidently get is worth its weight in gold.  The ability to solder in situ without melting adjoining plastic is superb.

Post by: Paul Swainson on April 05, 2015, 04:17:20 PM
Like the soldering Joe, you talk in the build of solder paste.  My soldering isdone with a fluid which lets the solder flow very quickly so that there are no lumps.  But I am still using solder on a coil and not much heat.  What is the type of solder paste you are using.  It is actual solder but in paste form with flux.
Title: Re: HMS Coventry build
Post by: radiojoe on April 05, 2015, 05:39:01 PM
Hi Paul  Yes it's a grey coloured paste made up of a self cleaning flux and powdered solder you just assemble the joint add a tiny bit of the paste and apply heat with a mini gas touch or a soldering iron and it instantly reverts to solder and runs though the joint, because the solder is already in the flux it leaves a hand free to steady the joint or using tweezers add a piece of brass with a bit of the paste on the end to the assembly, it requires so little heat you can assemble parts close to previous joints, the paste is used a lot in the electronic printed circuit industry, I know I'll never go back to coil solder. :-))

Post by: radiojoe on April 06, 2015, 09:49:23 AM
Hi Paul, yes that would be it but they also do a low temperature paste which is better for what we use it for, I get mine from ebay, I've just ordered some more two 50g pots for just over 5 post free from Hong Kong.  there are a lot of reflow fluxes around that some call soldering paste so be careful

Don't remind me Ned. As a young JTO I was being a bit lippy to the Killick Bunting and for my punishment I was sent up the mast with
a pot of white paint - Start at the AJE and work back painting both yardarms and it looked a hell of a long way down to the bottom of the
Simonstown Drydock. Thank god I had a reasonable head for heights - no safety harness just a piece of nylon halyard tied round the waist

Well Ned the plan I'm using is for HMS Glasgow and dose show the item you mention, but the photo of HMS Coventry taken in 1979 that I'm basing my build on doesn't show them, so I'm assuming they were part of the post Falklands refits, but then I'm not claiming to be that accurate as the 42's had many small differences ie. some had three yardarm's on the aft mast and some had two, so it lets me get away with a few boo boos.  %%

Did her final trim tests today with her boats resting on top of the davits to get sailing weight, just a slight list to port soon corrected with a few .22 pellets on starbd deck amidships, now glued in the hull below water line, also gave the motors a test, she only just fits the domestic dock and it needs to be two thirds full to get a couple of inches clearance, at a third throttle there is plenty of "boiling water" astern, if I had given any more throttle I think her bow would have shot up the slopped end so I think she should run quite nicely. ;)

Gorgeous Joe! You should have plenty of time to get her through her trials before your show in July. It has been a pleasure to read your posts and see Coventry go from a hull to the completed article. Is she good and stable?
Title: Re: HMS Coventry build
Post by: radiojoe on April 08, 2015, 02:41:54 PM
Thank you Ian,  Just like the full size batch 1 and 2  42's stability is not going to be a strong point, and I think she'll only be sailed in calm conditions with her large flat sided superstructure wind will always be a problem, It's difficult to assess in the domestic dock but I did a inclination test by pulling the top of mast to the side till the gunwalls were almost in the water and she wanted to straiten up when I let go, though did roll a bit, but then you do get water reaction in a small area off the sides of the bath, so I guess only sea trials will tell,  We used to do similar inclination tests when I worked in the boat building industry, though it was done by loading a given number of 25 kilo weights on the side decks. :-))
Title: Re: HMS Coventry build
Post by: T888 on April 08, 2015, 04:35:20 PM
Joe,
If you have kept the top weight down then it should be OK ,my 42 has sailed in the sea off my works jetty on the solent,in moderate sea condition and she Handel the sea well. I've also sailed on the mast pond at Action stations in moderate conditions.


With my 42,s I've got the battery and motors are as low in the hull as they can be , superstructure as light as possible with out losing strength.


Hope to see some pic's when she get her feed wet for the first time.
Title: Re: HMS Coventry build
Post by: radiojoe on April 08, 2015, 06:10:03 PM
Hi Dave,  I'm glad I hollowed out the raydomes and decided to make my own funnel which is a fraction of the weight of a cast one, plus the motors are close to the hull and the batteries sit on the bottom and with the two lumps of lead slung under the keel I'm quietly confident that she'll sail well.  %%

She sits well in the water and as an ex Chief Stoker, I'm pleased to note that her trim on the waterline is spot-on.

T888's advice is particularly sound at 1:96 scale.

well coming to the end of a very enjoyable build, finished her aerial system/rigging today and fitted her boats, just the Lynx to make now that will only be on board for exhibitions, again wasn't that happy with the resin moulding the split mould was obviously poorly fitting resulting in a "step" in the fuselarge but with a bit of careful carving and sanding I managed to make it usable, I'll make my own main rotors so they can be folded.
Hope to get the trials done next week I'll wait for ideal conditions for the first time, I like to assess the performance without too much input by wind and choppy waters.  :-))

Yes I have seen some of Shapeways fittings, still a bit on the pricy side a 1:200 Lynx at 30 euros heaven knows what a 1:96 one would be, like every thing I'm sure it time they will be cheaper, to be honest the Lynx was never intended as part of the build of Coventry, it was just in with some fittings I got from Sirmar and although a very poor moulding I thought I would see what I could do with it, it's now just about OK for popping on the deck at exhibitions.

This morning conditions in my garden seemed ideal for sea trials, so with a bit of trepidation as I always get when committing a boat you have spent hundreds of hours on to the expanse of the lake I set off,  when I got there it was a bit more breezy than at home it tends to blow along the creek next to the lake but the water was quite calm, I thought well I'm here now so might as well go for it.
After launching Coventry with the slings in the water as predicted the wind did have an effect on her catching her broadside on it tended to push her sideways and made her lean a bit, the effect was quite a lot less when under power with just a occasional gust catching her, started off with slow turns she responds very well and gradually worked up to full power tight turns it was clear she was not going to roll over even given the wind factor, on one fast turn with the wind in her side the inner prop cavitated so I put a bit more weight inside under the hanger I say weight it was infact my bunch of keys, this had an immediate improvement so now I will tweak the ballast a bit, all in all I'm very happy with Coventry 's performance, and after thrashing her about for an hour inside was bone dry and the motors barely warm. :-))

I appreciate that there have been many build logs on the Springer, but if you are bringing new ideas and methods to your construction, and you don't mind putting up the piccies, I am sure many would be interested to see what you do. Even if it a truncated blog with just important points.

Then, if you have a future super project on the cards, you can go the whole hog telling us how you build that.

Again I would just like to thank all you chaps for your encouraging comments thoughout the build of Coventry since joining Mayhem and seeing all the great builds you guys do has really made me up my game and attempt things I previously would have shied away from.   :-)) :-))

Just an update, now Coventry's had a few sailings it became clear the working stabilizers were neither use nor ornament (as my old mum used to say) so I decided to deactivate them, the simplest whey was to remove the rods and arms degrease the shafts/tubes and epoxy in place, at least I enjoyed working out how to do the mechanics and make them work, and the rods and arms will come in for future projects.

Hi Joe, I wonder if the reaction to them fitted to the real ship was the same as you found.  Still a nice build Joe.

Hi Paul, I was told by friend who served on Coventry  who said the so called stabilizers were seldom used and then only in certain sea conditions, they had some weird effects on my Coventry so I think it'll be better off without them.  O0

Could have left them active but never used (just like the real thing), then when on the viewing stand its a little feature that the kids see and wonder what they are - a bit of fun, saying its like a fish, again on the water you just don't have them running.

I deactivated them because they were linked to the rudders, I could of used a separate servo for them but to be honest they weren't worth the bother. %% %%

Hi,
I can imagine you got some odd results from your stabilisers. The real things were turned off when precise manoeuvring was required sailing into port etc. The ship would lean more in the turns. The turns were calculated by the navy. He had a book with graphs for the very purpose.
When not carrying out precise manoeuvres ,just going from A-B or sailing around a box on the chart. We did a lot of that , to save fuel just one engine on low power. The stabilisers were on. I do recall times when they were off for maintenance,the tannoy would an announce it. The bloomin thing seemed to roll all the time to me regardless. They must have done something I suppose, crew comfort was not the highest priority to the 42's designers.

Mm interesting will see how mine fair in Tiger, they are computer controlled so could be fun, very responsive

 joe , Rob ,
Any chance you could video your tiger with the stabilisers on and off ? I would be interested to see how they effect a model.
Cheers paul

This is the first time I have seen this build and model.
What an absolute beauty.
Congratulations on such a superb model

Hi there

I too would be interested to see how the stabilisers performed in a video .. due to the fact that when I built Leeds Castle, which had independent control of stabilisers which worked from a free swinging pendulum, mounted into the centre of stability axis of the model, and this pendulum has sensors on it which picked up which way the pendulum moved.  The problem being, you cannot get the model to respond and roll like a 'real' ship as the model movement tends to be too quick and jerky.  Therefore the sensor system used to over react and sometimes you could get a quick corkscrewing movement out of the model.  Other times it wasnt noticable, you could see the stabilisers working but the model not really responding. The Leeds Castle is 1:48 scale.

hi there 3rd attempt hope this works

3 photographs of the internals of the LEEDS CASTLE - first one should be the pendulum which is mounted between the 2 main drive motors

2nd one should be of the part of the electronics which basically is a heavily modified servo driver

3rd one - 2 drive servos which drive the stabilisers independently

Joe, utmost respect to you for a job extremely well done.

In Naval parlance: BRAVO ZULU!

If I'm correct in assuming that you sail on Walpole Lake in Gosport then I look forward to seeing COVENTRY on that lake soon.

We launched our version of War Department Train Ferry No3 on that very lake today and were blessed with good weather, calm water and light winds, critical for a vessel with such a low freeboard.

Whilst discussing the stabilisers on HMS COVENTRY I'm reminded of a sad tale regarding her sinking and her stabilisers. As the ship's company abandoned ship, her First Lieutenant was almost last to leave. As he slid down the heavily listing ship's side, and being uninjured, he apparently caught his chin on a still extended stabiliser fin, was seriously injured and perished as a result.

Our thoughts go out to his and all of the families bereaved in the Falklands Conflict, especially as Armistice Day approaches.

Your excellent model should be a fitting memorial to those lost aboard the COVENTRY.

Kind regards,

Sandy.

Hi Sandy
Thanks but there seems to be some confusion Coventry was completed 18 months ago.

Hey Joe, been awhile since I have been on here. Your build is amazing, museum quality. Something to be proud of for sure. Looks awesome on the water, well done!! :-))
