Title: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on April 19, 2020, 01:03:05 pm
Hi.


Needing a rest from the Riva, I have decided to greatly modify a 41inch Huntsman to become a "Sports Fisherman".


This came about as having received a Slec kit as a gift and on looking at the picture of the finished model I thought that the fore deck was too fat and stubby, also, I think


that the builders/designers tried to get too much accommodation etc. into 31ft with a loss of open deck space.


Have roughly drawn out the modifications and I like it, a bit different !


Here is a photo of my rough sketch. Will post as building progresses if there is enough interest.

I think there will be interest in this one Mike - there are a number of members building fairey marine models just now  O0


Hope your idea takes off (but not literally)  %%

Hi Mark

I recognise part of that boat! The Huntsman 31 has a fine looking hull but the aft cabin version doesn't show it off to its full advantage - but that's what customers wanted, accommodation. Hence why I've decided to build the Sport version.

Good to see you making a start on the build. Just a suggestion, as you've gone for sharper, more modern lines to the superstructure the side air vents off the later Faireys, but reduced in length, would look good.


Chris

Chris.

I will give some thought to your suggestion regarding the side air vents, especially as they will be the main source of a cold air supply to the fans for cooling motors and batteries. The ESC's will be water cooled of course.

Hi.


Building started now, I need to complete the hull first up to the point where the bottom and side skins are fitted, then I can start the modifications.


The first job was to lighten the the frames and the keel, then complete the build up to the fitting of skins to allow me to make chine rails by overlapping the side skin over the bottom, this brings the hull up to modern design and saves the fitting of 1/4 round as the full size. I will also replace the spray rails, which were half round, using triangular which I will have to make as I can't find a supplier of ready made. The new rails will be spaced differently from the norm. I need now to drill for the 2 prop shafts and rudders.


I now need to make the rudder tubes which will be 8mm thick wall brass tube, with Delrin type engineering plastic bearings top and bottom with O rings top and bottom.
The  prop shafts will again be the same 8mm tube with stainless steel ball races on the inboard end and Delrin at the outboard end, 4mm S/S exposed shafts.


I will be fitting 2 x 1kw brushless motors mounted with 7mm rubber bobbin mounts and the forward thrust taken up by ball raced thrust bearings, the reverse will be handled by the 2 spiral couplings, (reverse set to 20%).
The last picture is the last remaining bulkhead to receive the lightening.

Some pictures.


Mike.

What's the thickness of the skins Mike, I'm guessing 1.5-2.0mm?
Well, they certainly look strong anyway.

All sounding good, looking forward to seeing the build progress. Do you add an oil tube to the rudder tube, or just grease on the o rings..?


Best regards
David.

Post by: ChrisF on April 23, 2020, 08:38:16 pm
Making good progress Mike. Interested to see how the flared bow is undertaken.

Like you I tried to source triangular timber but no luck so have used square section I've rounded off which is OK on my smaller model. I did find some in styrene or similar which I think was 5 x 5mm which might be an answer for a model of your size.

Chris


Edit: Just Googled and found a couple of modelling suppliers who have Plastruct in various sizes up to 3.5mm. Don't know how I missed that when looking for the Huntsman 28. May give it a go on the Huntsman 31.

Evening all.


Capt. Podge.... The skins are 1.5mm birch ply and getting it to bend at the last bow bulkhead was a nightmare, no glue on earth would have held it, I finished up by soaking it at the last, (first), 2 bulkheads in boiling water then clamping it around a 125mm parallel plant pot left over night to dry, worked well.




David.... No oiler tubes there will be PTFE loaded Lithium food grade grease in the tubes and very easy to pop the shaft out for maintenance if required. The Delrin bushes have half round groove machined into the bush where the O rings sit so they are in fact captive.


ChrisF.... Re the triangle stock, I've made my own using 6mm Limewood, not Basswood, as, contrary to popular belief they are not the same. Limewood is easier to work.

Also, forgot to say that I intend re shape the transom from curved to flat. The chine rails in the photo's,( the Orange tape was just to make them more visible for photo purposes), are not finished as I need to add wood capping to make them flat to the bottom skin, as though they were triangular, not just side skin.

Mike.
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on May 03, 2020, 07:45:08 pm
A little more progress.


Have finalised the motor mounting with the rubber bobbin mounts and re positioned the motor position, bringing it back by 200mm toward the stern.


Also, as part of the, "make over", the transom has been re shaped and flattened by 40mm. thus reducing the curve.


Have made the rudders which are hollow and aerofoil section and 5mm shafts, the tubes are 8mm thick wall brass with UHMWPE plastic top and bottom bearings.


There are twin O rings per tube which negates any chance of water ingress.


The short internal prop shaft tubes are the same 8mm brass with sealed ball races at the motor end and UHMWPE bearings with twin O rings per shaft at the hull exit,


The shafts are of the the exposed type with thrust bearings fitted just before the 2 spiral couplings which will stop any thrust reaching the motor.


A few pictures.

Mike.

Hi Mike......


These rubber resilient motor mount elements....were they for noise resonance elimination against the mounting plate?......and I suppose there is no motor casing sag? [weight influence] due to the semi rigid axial characteristics of the couplings


Derek
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on May 04, 2020, 07:23:42 am
Hello Derek.


Your assumptions are quite right, in that their prime function is to eliminate any motor noise being transmitted into the hull and subsequently amplified, (I hate unnecessary noise ).


There is an added advantage also, they seem to absorb the initial kick back that most outrunner motors create on start up, which makes the whole transmission  more gentle.


The mounts that I've used this time are quite flexible and the amount of flex can be controlled by sinking them into the wooden mount. This I have done by using quite thick  high quality  ply and boring flat bottomed  pockets that the mount sits into. The pocket diameter is necessarily quite critical as the fit of the rubber must be quite tight. The depth can then be controlled by adding or removing washers as spaces to set the amount of rubber outside of the pocket which determines the amount of flex, the deeper the mounts are let in the less flex and vice versa. It works.


I was lucky, in that the diameter of the mounts were exactly 8mm so was able to bore the pockets using a 8mm centre cut milling cutter for a perfectly flat square bottom and a snug fit.


There is no noticeable weight influenced sag .

Hi Mike
I am using the same drive coupling as you on a model I am updating to a large brushless. It's not been in the water yet. However another boater has said to me these couplings come from printer applications and they are not great at handling high torque. They feel pretty strong to me have you done any research on these couplings?

Hello Hurricane.


I've used these on several builds now without any problems, mostly on 50 size outrunners.


I use the cheap Chinese types as having spoken to a British manufacturer of them wanted £12.50 each and as the specs were both the same , no brainer .


I have some spare ones here, so if you let me know the size you need I may have some. Mine will be the best price also as they will be free, just postage.

Hi Joe.
I made them, but will be making some new rudder and propshaft tubes, due in part to the weight of the brass and the fact that I think the rudder tubes are too short, so, the new ones will be a fair bit longer..
They will be K3 carbon fibre and weigh a small fraction of the metal ones. Should receive the tube early next week. Also, I may re make a pair of rudder blades from the same C/F, as flat plate is now readily available.
Will post pictures when finished.

Hey Mike


Carbon Fibre for rudder and propshaft fittings, I like that. Looking at my brass rudder shafts now and feeling  bit inadequate...  {:-{  (And overweight)


My Aquarama is going on a weight loss program, looking a bit like Swiss cheese... Pictures tomorrow.


Can't wait to see the CF results..! Hope all's well.

Post by: ChrisF on May 10, 2020, 09:36:13 pm
Hi Mike

You're certainly right about the weight of brass. I was going to use a 5mm inner shaft with a 10mm OD tube in my smaller 1:12 build but it weighs a tonne and looks too bulky so I'm changing to 4mm/8mm as per my Huntsman 28 build.

Excellent build as usual and looking forward to your CF parts.

Chris

Post by: ukmike on May 10, 2020, 09:55:56 pm
Evening Chris.


 I agree that the 10mm with 5mm shafts are far too heavy and would be an overkill. My wife's little Smart Car drive shafts are not that much bigger than that 😀.


I believe that your preference is for Rabosch maintenance free shafts, although pricey, you would be better using them.

Keep well.

Mike.

Post by: ChrisF on May 10, 2020, 10:07:48 pm
Hi Mike


That's what I am using. Fine in the Swordsman 33 which is a much bigger/beamier hull and a bigger motor but no way in the H31. General advice is to use 5mm for a long prop shaft, the one I'm using is 490mm, but being Raboesch I'm sure the 4mm will be fine. I don't think they'd make it otherwise.


I don't know what I was thinking, well that was the problem, I didn't!  :embarrassed:
Chris
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on May 10, 2020, 10:30:32 pm
Chris.


490mm long shaft ! That seems very long, although all of the Fairy models seem to have the motor under the fwd cabin. It's the same with the Slec 47in. Huntsman


I just had to do something about that, which I thought was totally ridiculous and have brought the motors back by 200 mm, which was relatively easy, whist still being able to maintaining a shallow shaft angle. I think they are on or almost on the C.G. now.


Mike.
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ChrisF on May 11, 2020, 10:20:49 am
Yes, long shafts - I did reduce the length in the H28 though and may have to in the H31. As said it's a result of the low angle, the length of the connector and the position of the bulkheads.

The latter can be got round though and I could move the motor a little further back.

Easier to do in bigger models of course and with twin motors etc. definitely something that needs to be done.

Hello.


Whilst awaiting the arrival of my C/F components, I decided to make the next few little things that the hull will need, so,to that end I've made a battery box and servo


mount as well as cutting the hardwood,(I would have preferred English Limewood but couldn't get it), lift strakes, which was very fiddly due to them being 125mm long,


especially as I needed each one to be identical, 6 in total, 4 for the boat and 2 spares.


Also, the chine spray rails are done, they are for the most part 10mm wide, tapering to nothing at the bow, the lift strakes will take care of low speed spray as well as


providing lift at medium and high speed


The overall weight of the transmission parts that I have so far, weigh 255g. about 9oz. not including the motors and couplings of course, as they weigh what they


weigh. I am aiming to almost halve that using the C/F components.


One of the photos, showing the chine spray rail and 2 lift strakes, also shows the exhaust tube and flange, these in themselves add 113gr.about 4oz. Both of these 


parts will be C/F.also, the battery box lightening provides the added advantage of cooling LiPo's.


Here are some photos, some of the parts are only held in in place by sticky tape for the photo purposes.

Hi.


Don't know what happened to yesterdays post but it all looked o.k. until I pressed Post, will have to ask Martin.


Anyway, some of the carbon parts arrived today and was able to fit the ball races into the prop shaft tubes which now need cutting to length.
Can't do anymore until the Acetal arrives so have started to make the P brackets but need some 2mm brass plate which needs ordering.


The picture shows the carbon that has arrived and the weight saving is incredible. For the uncut lengths of tube, plus 2x5mm dia. Pultruded carbon rudder shafts, the weight is as shown on the scales, all that you see, including the 2 shaft ball races, weighs in at 12 gr. or 0.434 oz.total.
I am more than delighted with the results, especially as I will not be using the full lengths.


Mike.

Post by: ukmike on May 20, 2020, 02:39:37 pm
Hi.


Carbon rudders and shaft tubes completed.


Unfortunately I had to use brass shafts for technical reasons but have reduced the dia. from 5 to 4mm, plenty tough enough as the top and bottom bearings


go 15mm each end into the tube.  A photo.

Hi Mike.
How did you produce the triangular profile of the lift strakes?
Are they machined or planed and how did you manage to keep them uniform over the required length?
I need to do something similar on the bottom of my SLEC Pilot boat, the build instructions say to shape down a 5mm sq obeche strip to half round
but that will not be very easy and they won't act as a lift strakes either.
Thanks.
Robbob
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on May 20, 2020, 06:10:07 pm
Hi Robb.


I totally agree with you, in that just rounding the corners of the 5mm square won't work very well, if at all.


I cut the lifting strakes on my little Record bandsaw.  I used the supplied wood which is 1220mm X 5mm square. I use a 3/8 wide blade with 24tpi and tension it  very high, (just for this job),  then set the table to the appropriate angle. Remove the plastic table insert and use the fence, back side of course, to set  and guide the cut.
I needed 4 pieces but made 6, just in case !!
It was a fiddle due to the length of the wood but if you are careful and keep the cut moving it's o.k.
The shorter the piece the easier it is.


Hope that helps.


Mike.

Post by: robbob on May 20, 2020, 06:21:46 pm
Hi Mike.
Thanks, that's very helpful  :-)) , I just wish I had a bandsaw to do the same :(( .
I'm considering making a 'v block' type jig with a 5mm groove and setting a milling cutter in my Dremel set parallel with the surface of the block with a minimal clearance and
drawing a 5mm sq strip through it to cut the top off, so to speak, to produce the required profile.
Do you suppose that might work?
BTW. I have seen balsa profiles for 'plane wing leading/trailing edges but the balsa will just not be robust enough even when coated with Z Poxy finishing resin.
Anyone else got a practical idea about this?
Thanks.
Robbob.

I'm in the same quandary. I used square section rounded off on my Huntsman 28 which is OK but on my Huntsman 31 I'd really like to use triangular. Earlier in the thread you can see I've found some styrene section that I might try. Some folks plane the square timber against a stop but like you I'm concerned about accuracy. I have a router but holding  small sections is difficult. Will give it some more thought.

Mike - very futuristic using CF.  Were you an engineer by trade?

I know how frustrating it is when you can't get the things that you really need for a project and have to accept a compromise. In my case, I find that I'm never happy with the result, which spoils the work already done.


So, if either of you can't get or make the tri stock that you really want, I will gladly cut some for you.


In answer to your question Chris, no, I wasn't an engineer.

Hi Mike.
Thanks for your generous offer.
I have made up a contraption that allows me to mill the square section to triangular and early test are proving successful but I need to make more than 6 metres of this
so I hope the results are repeatable.

Mike - thanks for the kind offer also. I shall have a go first though as I haven't tried yet.

Robbob - ingenious! My first thought was to router out a vee for the length required, drop the square section into it and then plane it down to size. But yours is probably a better way.

The results are a bit variable, not as clean and consistent as planing but good enough.

I might just try what you suggest as an alternative too, I do have a router and a suitable bit.

I'm pleased to see that there are a few die-hards out there who are prepared to go the extra mile to make H31 as real as possible. The case of the spray rails is an obvious one -
The real thing does have triangular-section rails which present a flat approach to the water. This is clearly what the designer intended and was incorporated into the hot-moulding tools used to make the hulls. Unfortunately not all modellers are either capable or willing to reproduce proper triangular spray-rails from wood strip on their models. The majority of kit builders will in all likelihood leave them off altogether. A half-round section is a reasonable compromise which satisfies both the aesthetics and the practicalities i.e it looks and works better than nowt!
I've fitted the proper section on a couple of my models and frankly it's a PITA. I have to admire the thinking behind the solution found by Mike and followed up by Rob and Chris so if any prospective builder of this kit fancies going down that road then I will encourage and admire them too. Just pity the poor kit designer who knows full well that maybe 60% of the kits sold will NEVER be built, and half of the rest will be put into the loft after a few fruitless attempts - with or without reference to the plans and instructions!

Hello All.


Due to the long delivery times I can't continue with the next job to be done on the hull, so, have made the 2 P bracket shaft tubes.


The problem with P brackets when used on exposed shaft systems, is getting some form of lubrication in order to prevent any overheating, which would ultimately result in the shaft and tube becoming so hot that they will eventually weld themselves together. Not a good situation !!
On full size boats, one way to address this problem is to use cutlass or curtless bearings in the bracket tube, these are inserts in the tubes, usually a form of rubber, with slots running the full length if the tube, at least 6 in each bearing. When the boat starts moving water is forced down the slots, thus providing water cooling. Of course they can't be run when out of the water as that too would cause the rubber to melt very quickly.


The same situation can occur on our models and in my case the shafts will be turning at about 12500rpm at full throttle, so wouldn't take long for a catastrophic meltdown to take place. As my shaft to tube fits have been made to very tight tolerances, a must if no vibration or early wear is to occur, I need to introduce some form of forced water cooling. This has been achieved by angle drilling the tubes at 6 points per tube so that water is forced between the 2 metals whilst the boat is moving. I further shaped the angled by elongating and polishing the lead in. I sure that, although my tolerances are very fine, little tiny water molecules will still be able to get in there and do the job.


I did make a pair of tubes from Bass with Phosphor Bronze bushes but I abandoned the idea due to the increase in the diameter of the Brass tubes to allow the bushes
to be used, also, cutting or filing grooves the full length of the tubes would be difficult for me.


So there you have it, job done and hopefully a success.


The photos show the finished items with a comparison between the smaller drilled tubes, thick wall very hard Brass, and the PB bushed type.

Hi Mike

Interesting what you're saying. Never considered that they'd be a problem with overheating when running in water but as you say at very high revs the temperatures reached will overcome the cooling effect of the water.

Did you consider Delrin for bushing? That's used in the bottom bush of the prop shafts that I'm using and they will run to 15,000 revs. I understand that they are lubricated by the water.

Chris
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on May 26, 2020, 08:08:02 pm
Hi Chris.


Delrin is basically Acetal plastic with a max temp of 85 degrees. I wouldn't trust it for my  transmission, although ,I am using Delrin on the rudder shaft tubes. Very easy to machine and inexpensive also.


Mike.
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ChrisF on May 27, 2020, 12:10:51 pm
Thanks Mike

Unfortunately us mere mortals have to use what we can buy readymade! I don't have the equipment or skills to manufacture anything like that.

I'm not concerned though as Delrin has very low friction and I can't see the temperature getting anywhere the maximum limit, Raboesch make quality stuff and I'm going to have to accept what they say about some of their prop shafts being suitable upto 15k.

To be honest the lake at our club isn't that big and would be very difficult if not impossible to attain max. speed except maybe the odd burst.

Do you know, out of interest what racing models use, bronze?

Chris

Hi Chris.
The Raboesh are very good, if you're happy using them its better to stick with what you know and trust, ( if it ain't broke, don't fix it ), as the saying goes.
I have no knowledge of racing boat setups, but if you ask David,  DJW on this site I believe that he's done it in the past.
Also, I throw away an awful lot of my ideas as they turn out to be complete flops, but some turn out  quite well and are used, unfortunately, there are more flops than successes.

Hi Mike and Chris


It was generally Oilite bushes in my Multi racing days when running conventional shafts, usually with oil in them. I'm making up my exposed propshaft and rudder assemblies using Lead / Teflon bushes from Prestwich Models, on the basis that if they're robust enough for full on racing using surface piercing hardware, they should be fine for my Aquarama P Brackets.


They're here: [size=78%]https://www.prestwich.ndirect.co.uk/surfacedrive.htm (https://www.prestwich.ndirect.co.uk/surfacedrive.htm)[/size]
(Then scroll down to 6 from the bottom)


Also here on ebay: [/size][size=78%]https://www.ebay.co.uk/itm/4-x-STEEL-TEFLON-4mm-id-6mm-od-bushings-rc-boat-brushless-bushes-bearings-/392167078697 (https://www.ebay.co.uk/itm/4-x-STEEL-TEFLON-4mm-id-6mm-od-bushings-rc-boat-brushless-bushes-bearings-/392167078697)[/size]


These bushes have a split, so when making up the P bracket its possible to get a good fit in the housing and on the shaft, the split also allows some water to pass through for lube and cooling. To this end I've allowed water to pass though between shaft and P bracket, to the front of the bush. (This can be a negative in the rudder tube so seals / O rings are required.)


But this is just my thoughts, I'll have to let you know in a couple of months whether it all works..  :-))

It seems that 2 heads are indeed better than one 😀.

Thanks for the information David. One of my next builds is going to have exposed prop shafts. Your P brackets look lovely. I see you have done away with the usual locking nut and used a grub screw to secure the prop which gives a nice neat look. Are they Prop Shop props (they look like it) which you have drilled and tapped for the grub screws?

Chris
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: DJW on May 27, 2020, 04:17:01 pm
Hi Chris


Ah yes, the props are from Prop shop, and they are beautiful.  And the grub screw approach is courtesy of UKMike..!  Drilled and tapped (M3 I think) then short grub screws.  I did put a flat on the shaft threads as I didn't want to risk stripping the threads in the prop hub. They'll be put in with loctite before heading to the lake.


This is before the conversion:

So the grub screw does look so much better.

Hello.


Hull glassed now and rubbed down, 1oz cloth on the bottom and transom with 1/2oz on the sides.


2 coats of Z Poxy finishing resin unthinned, rubbing down between coats, no need for thinning as I always sand the majority of the resin away.


Have marked out the position of the lifting strakes on one side with tape and given it a dusting of primer, which also shows any surface filling that might be needed.


Fortunately, all looks good so none needed.


The photos show the results and the positioning of the strakes and the main spray rail that is already built into the hull sides.


Also, picture for ChisF of the bow flair.

Post by: ChrisF on June 02, 2020, 10:23:53 pm
Hi Mike

You've made a nice job of the bow - to be expected of course! How did you manage to do the sides in one piece apart from the small block at the bow given the compound curvature? I did it in two and had to use thinner ply to the bow area. And did you put some additional timber in to support the edge of the ply to maintain the vertical strip for the rubbing strip? Here's a photo of mine before cloth and resin, only 2/3 the size though. I'm going to build another hull for the aft cabin version of the Huntsman 31 and have introduced some additional small frames to form the flare.


Chris

Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on June 02, 2020, 11:04:03 pm
Hi Chris.
I pre shaped that part of the ply, about 150mm long, by soaking in boiling water with a little washing up liquid added until I got fed up of boiling the kettle several times.
I then taped it around a cylindrical flower pot 120mm diameter and then left it overnight to dry.
The cylinder was layed long ways of course.
It's easier to fit the side starting bow first.
I held the ply in place using a pin pusher and brass pins, plus glue of course
I use a pin pusher and brass pins to hold almost all wooden parts in my models.
Your extra frames idea sounds a good way to go but would be helped by pre bending.
Hope that all makes sense.

Very nice hull form coming through. I know it's a classic, but as Chris said that hull is not easy to get the compound curves correct.

Hi David.


I'm a little disappointed that I couldn't change change the overall shape of the bow very much, so it has to do.


Have decided not to use the 3 strakes but will now be fitting only two, also, reversing the the order and alter the


curve by flattening it out somewhat. Being only 2 it will appear that the bottom one is then the shortest and


there will be a sight increase in the size too.


This is because 3 were unnecessary and esthetically ugly, too much like the original boat.


I've worked out that the lift available will be just as as much as the 3 setup and a lot more pleasing to the eye.


Will post a picture showing the new setup, all be it held in place with tape.


Mike.

She's going to be a hybrid for sure..!  Are you planning to keep the strakes full length of the hull..?  I ask as does the stern need them..?  Might be easier in planing turns if the stern of the hull doesn't have the extra grip on the water that the sharp edged strakes will give, so the stern can slide sideways with rudder applied. Given the profusion of carbon fibre that stern is't going to be heavy..!  :-))


Best regards

Good process, it is a tricky hull to get right and I'm not 100% happy with mine. Bit trickier being a smaller hull at 31" - well that's my excuse anyway!

Re. David's comment. I know yours isn't a Huntsman now but on the full-sized boats, being twin props the strakes stop well short of the stern and are staggered.

Chris
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on June 03, 2020, 01:27:13 pm
After looking at many photos of the the original boat, an awful lot of them have have been fitted with trim tabs, I assume because the very severe angle of the "V"
 
didn't provide enough lift to flatten the planing

Therefore, that is the reason for the fitting of lifting strakes,( not spray rails ) and why they will go all the way to the transom. That's my take on it and saves the need
 
trim tabs.

A few pictures, not fitted, just held in place with tape


Mike.

Post by: DaveM on June 03, 2020, 04:21:22 pm
Some of those trim tabs were actually nothing more than anti-cavitation plates. Photo of Mirak Huntsman 31 restoration project by Scott Pett.
I've built several different models of Huntsman 31 in three different scales, and I'm now convinced the only real way to fabricate that bow flare properly in wood is either to use block balsa or double-diagonal planking. Even a very creditable job like the one you've done won't avoid a 'lump' somewhere along the curve. It's like trying to cover the inside of a big spoon with sheet plywood!

All the rails fitted and have given it a light coat of primer just to show up any imperfections, of which there are many.


Will put that all right and put on another coat, hopefully all will be O.K.


If so, I will sand the bulk of it away ready for the final colour.


I have to admit to not being very pleased with it so far, as there is quite lot of fettling to be done.

Mike - that's not a problem. In the modern parlance it's a challenge. I've always said that the difference between Mrs Milbs #1 and #2 is that #1 could spot the only brush-hair I'd left after glossing a whole door, whereas #2 stands back and says "That looks FANTASTIC!"

Hello.


Some changes to the motor mounting system, gone from wood to Aluminium and it is far better and more accurate.


Another coat of White primer to show up any fine defects, they will be corrected and then the majority of it will be sanded away.


When the hull is complete I'll carry on with the altered superstructure with the addition of a flying bridge with second helm position, still keeping the original wheelhouse


but heavily modified.


Some pictures of the state of play.

Good Afternoon.


If it's of any interest to anyone, here are some pictures of the prop shaft thrust bearing set up.


All of the fwd thrust is taken at this point, so nothing reaches the spiral coupling or motor bearings.


This method only works when the boat is going ahead, but, because the reverse maximum revs are limited to 20% when full astern, the spiral coupling will easily


handle what little thrust is presented to it


I've tested it and it works very well.


Mike.

Evening David.


That's right, but first I need to find out why the carbon rudder blades don't like being painted. There is some sort of reaction that causes the weave pattern to show

through the applied primer, no matter what type of primer used. It's annoying but I'll solve it one way or another.

Will finally get the Riva windscreen frame back from the platers next week so this build will have to stop and the the Riva will take over.

Looking forward to that.

Hi Mike,


Would you mind letting me know what size of Surpass brushless motors you are using please?


I need to buy a suitable pair of motors for my similar size (48") Chris Craft Corvette, but I am not sure what size of motor and prop to use.


Thanks,


Bob.

Evening Bob.

Thanks Mike,


 I am not too knowledgable about brushless motors - but I have been lucky so far in choosing ones that just happen to work well in the boats I have fitted them into, but my 48" vintage Chris Craft Corvette will be my first twin shaft model that will be powered by a pair of brushless motors.


I actually bought a pair of Surpass C3542 (2820) 1450KV motors online, but when they arrived I thought they looked a bit "skimpy" to power such a big lump!


When I saw the pictures of your similar sized project with what looked like the "same size" motors I thought I would ask you about the spec as these little motors are available in three different KV ratings. I chose the 1450KV type - only because that is similar to the KV rating that has worked well with my other brushless motors, and not because of any educated reasoning!


Since buying them I am uncertain if I have made the right choice. Maybe the lower KV rated motors would have been a better choice and turn a larger prop - or maybe I would be better off with a pair of physically bigger motors?


I have other smaller classic  projects "on the go" that these motors should work OK in, so I would not be too worried if a different choice of brushless motor would suite the Corvette better?


I like my classic model boats of this type to perform authentically well,  and not just amble around the lake as the "real thing" does perform well and so I want my model to be able to replicate this same "white water" performance!


Any advice would be appreciated regarding the KV choice and can size for this size of craft.


Bob.

Post by: ukmike on August 16, 2020, 12:29:29 pm
Hi Bob.


The 3548 seems to be unavailable now, so I would use the 3542/05 version now. Banggood have them @ £ 17.64 each + £1.03 postage. Same postage if you order 2.


The Tornado Thumper is exactly the same motor and available here in the U.K. for about £10 per motor more.


They should be good for your Chris Craft as long as it's not too heavy, 4.0 to 4.5 Kg. or less would be O.K.


Hope that helps.

Thanks Mike,
 
The 3542/05 motors that you suggest have 1250KV, the 3542 motors that I already have are 1450KV.  I don't really understand how the KV ratings work.  Would the lower KV give more torque and is why they would be more suitable for my 48" Corvette, and would you let me know what KV motor you have chosen for your Huntsman please?


As a matter of interest, I see today that Bangood are now also showing the 3548 motors as being in stock again and have a choice of three - 790KV, 900KV and 1100KV to choose from, as well as 1100KV, 1250V and 1450KV versions of the 3542 and they are all the same price - £17.34.


At the moment I am "confused of Rossendale", but hope to learn how to choose the right motors for my Corvette as the reasoning will help me with my future choices too!


Stay safe!


Bob.

Sorry for the mix up.


I couldn't find the 3548 motors on Banggood.


I am using the 1100 kv and they should be O.K.for your build. Very gentle start up, which is something that an awful lot of out runner brushless motors don't do, they tend to suddenly burst into life at quite high revs. In runners are even worse for that.

Do you have any idea what the likely approximate finished weight of the boat will be ?

Mike.
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on August 16, 2020, 09:48:49 pm
Me again Bob.

Further to the 3548/1100.

The 1100 watts is assuming that you use 4 cell LiPo's. That will make the the total Horse Power available per motor to 1.5 , so, you will have around 3 H.P. in total for your boat, reduce the watts and a reduction in H.P. will follow.
That applies to all brushless motors.
The KV the refers to the revs per volt of the motor battery. i.e. 1100kv connected to a 4 cell LiPo will give a theoretical RPM of 16200 rpm, ( KV1100x14.8v 4 cell LiPo ).

There is no more torque to be had in choosing a lower kv motor, just lower maximum revs available, although, the lower kv motor will draw less power from the batteries making it possible to use lower amperage ESC's which are invariably cheaper to buy.

Hi Mike,


I have just popped out to the workshop and weighed the Corvette on a pair of bathroom scales at approximately 10lb, but the boat is not finished yet


Add to the weight:-  x2 each of water cooled motor mounts, motors, prop shafts and couplings,  two cell 5500 LiPo packs, cooling pick-ups, outlets and tubing, glass fibre to fix the motor mounts and blend in the shafts and final finishing details and paint to get closer to the finished weight.


I will try to work out the weight of all that, but it could easily be another 5lb so the all up weight of the Corvette (with two LiPos) could easily be 15lbs, which is not that bad for a bulky 48" cabin cruiser........and it may need some ballast to get it down to the marks...........


That will probably be a fair bit heavier than your similar sized Huntsman variant and the bulky round bilge hull may not plane as easily either.


We will have to see.........


Stay safe,


Bob.
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on August 16, 2020, 10:34:58 pm
Hi Bob.


All is becoming clear now.


If it's a round bilge hull then it certainly won't plane.
That means that you don't need a high kv motor, the 900kv will be more than adequate for you.
You will also gain by using a smaller ESC and longer battery life too.
It's win win I think.


Mike.
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on August 19, 2020, 09:59:14 pm
Evening Bob.

I've just looked at your corvette and notice that the hull is not a round bilge at all, but a shallow V with a small keel which should plane quite nicely.

I would stick with the Surpass motors, they seem to be perfect for the performance that you want. Also, it doesn't need to scream about the lake, that would look silly, but, still be able to lift it's skirts when needed and elegantly show what it can do, as the design deserves. It's going to be a lovely boat when finished and a credit to your building skills

Mike.




Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: zooma on August 19, 2020, 10:37:46 pm
Evening Mike,


You are right - it is a shallow "V" and not a true round bilge. I have too many hulls "on the go" at the moment ......and a poor memory does not help much either !

I ordered the 1100KV Surpass motors (from Bangood) and they are already on the way to me. I have used a pair of 3542-1450 Surpass motors to align the prop shafts as I fit them, and I will change the motors over when the new ones arrive.


If the boat is too fast I would be happy to use the motors in a different model and replace them with a more thrifty 900KV to help gain a longer run time.


The boat is too big to "fly," and I don't want it to be unrealistic, but I have been looking at some video of the real thing and it does "get a shift on" and makes some nice "white water" and that is what I would like to replicate.


Thanks for your help.

Good Afternoon all.

Having temporally stopped work on the Riva, I've been doing a little work on this one.

As I'm making it up as I go along, progress is very slow due to me not being able to decide exactly how I want the boat to look, but I now have a plan in my head on which way to go, so, here are a few pictures of the work so far, not very much really.

The cabin sides widow cutouts  are not finished as I need to decide on the the size and shape of it, or them in the remaining space, I'm leaning toward 1, picture 2039.
The huge missing part of the foredeck is due to the Fairy only having a tiny foredeck, so the part supplied in the kit was as you can see, a tad small.
I'll fill that without difficulty but it will be a bit of a fiddle as the deck is bowed, picture 2041.

The front window will be 1 piece Plexiglass with a darkish tint, shaped as a big curve running back to the sides.

The flying bridge will be removable if needed and will be about 80% of the length of the wheelhouse/forward cabin/saloon.

Off to SLEC tomorrow as I need some wood.
That's about all for now as I can feel a headache coming on, just one of many I think. >>:-( >>:-( :-))

Hi.

I always try to pre bend plywood parts that need it, mainly so as not to build in unnecessary stresses that can be troublesome later in the build.

My next stage is to make the cabin roof and the front windscreen frame that will be cut after bending.

Some pictures of how I did it, simple and somewhat Heath Robinson, but it works.

The roof is only curved slightly, about 5.5mm at the centre. I used a piece of 6.4mm square the full length in the centre which was clamped along the outside.

The windscreen is simply held into shape using an elastic band and then packed on the inside until the desired shape reached.

Both pieces were soaked in water which was mixed with a little W/Up liquid and then layed in the Sun to dry. Speaking of W/U liquid solution, try to only use the

"Basics" type and keep the posh stuff for the kitchen, there are some additives in the more expensive brands that inhibit the action on wood somewhat that shows up

as not doing a very good job at softening or, very important to me, i.e. closing pin holes and levelling bruising.

Many of you will no doubt know all this, but some don't, so it maybe it will be of help to them.

Here are the pictures.

Mike.

Afternoon all.

A little more work on the "UKM-46"

I've changed several pieces since the last post and probably will change some again as the build progresses The cabin sides have been shortened and the window cutouts altered slightly and will be changed a little more by enlarging a tad. The floor is just laid in place at this time as the 4mm plywood used is quite warped and has many surface faults to be filled before I can permanently fit it, following painting which can't be done in situ.

The cabin roof isn't cut to size or shaped yet and is shown with a jar of Lead holding it down as the 3mm ply is also warped and twisted. Needless to say my supplier of all wood has been changed. Their ply is much better quality and the hardwood is superb, not that much more expensive either as well as being just down the road.

Much of the painting will have to be done before the parts can be permanently fitted due to it being impossible to spray in situ and to have any chance of achieving an acceptable finish. I doubt that will happen this year as the temperature is now to low. That also applies to my big Riva Special.

Until the cabin roof is completed I can't start building the flying bridge or make any interior fixtures and fittings but any metal work isn't affected as the can be done come what may.

The mini jigsaw is proving to be very handy

Here are some pictures, BTW the piece of varnished Mahogany is to make the louvre door to the front cabin.

I don't think I will be able to help you much due to the fact that that I have only built the bare hull from the SLEC kit and that has been modified quite a lot. The bow has been re shaped along with the transom. The rest of the wood in the kit has been cut up and used in the build.
The rest of my build owes absolutely nothing whatsoever to the kit, but I can say that the wood quality is at best "reasonable", especially as much of the plywood is quite warped and the hull frames are a little flimsy and prone to bending, they should have been 4mm and not 3mm. I can't comment on the SLEC Fairy range as I've not built any of them.

Sorry, I wish I could have helped you.

Mike.

It’s a shame that it is getting so hard to find any really good quality strip wood and plywood for model making these days.


I have been buying my birch plywood from SLEC as they are better than my previous supply from J.Perkins, but when looking at the wood it does not compare well with what I see in some of my old original LesRo kits.


By contrast some of the strip wood in my early Aerokits kits was really poor - dry, brittle, and sometimes not very smooth either!


The wood used in some of the American made model boat kits can be even worse!

At the moment the plywood and strip wood from SLEC is the best I have been able to find, but it would be nice to find a source with quality like LesRo were able to include in their kits.

Hi Zooma.

I have changed my supplier also. I am buying all wood now from Hobbies who are handily only 20 mins. down the road from me.
The last order was for 3mm  Birch ply, 3mm lite ply ,3mm and 5mm Genuine Mahogany, not Sapele which is often sold as Mahogany.
The very high quality of the both ply and hardwood is the best that I have ever and the prices are reasonable as are carriage charges , £5.99 for orders up to £150 and free over that
Won't use anyone else now.

Here is the progress over these last few days, work is quite slow due to not having any plans or drawings to follow. All of those things are in my head so I can only visualise the next stage, then get on and do it, often making a part 2 or 3 times before it's right, Wastes an awful lot of time and materials but well worth it.

Anyway, here are some photos. I don't know how to add text between each picture so I'll explain each photo first.

Photo 90 shows the cabin roof pinned in place but not yet finally shaped at the front screen overhang, no screen cut out yet as the 3mm ply is drying following a soaking in boiling water with added Ammonia, hence the yellow appearance. It's well worth the the fiddly method because I will end up with a perfect that needs absolutely no pressure to hold in place.

Photos 91 and 93  shows the cabin sides jigs holding the inward lean angle perfect each side.

Photo 94 and 95 shows the hull floor temporally in place, the coloured spots are lightweight fine surface filler to correct the faults in the plywood.

Photo 97 gives some idea of the lines.

Looking good to me.  The lines of the new superstructure are starting to come through, I think it's all going to look nicely balanced.


Very best regards

I would appreciate your thoughts on the front windscreen.

Would you leave it as split, as is, or maybe thin the central upright a tad ?

Or else remove it altogether leaving just the whole screen as one piece ?

Option 1 is the easiest,  option 2 is the more difficult as I would have to heat shape the 2mm Lexon as it's quite stiff.

There will be an Aluminium frame for both options and an apron along the bottom.

Give it some thought if you would and let me know.

A couple of pictures showing where I am with it so far.

I think the current split design is optimal too. Fitting design given vintage of the original boat.
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on October 25, 2020, 10:39:57 pm
Thanks for your opinions chaps, much appreciated.

I will be using the split screen, apart from it being the easiest of the two options, I noticed that the SLEC  Huntsman 47" doesn't have the split front screen the same as the full size which is also flat, which I don't like very much.

Hopefully that will remove any remaining similarity between my build and the SLEC kit/full size.

Mike.

Good Evening All.


A little more work on the boat at last.

Picture 2141 shows the Gunwale cap from 3mm x 7mm Limewood. It was soaked in near boiling water with added Ammonia for 30 mins. any more would have made it too soft. It was shaped and held in place with Brass pins and left overnight to dry. Bending it was quite straight forward apart from the very tight curve at the bow.


Pic.2160 is the Mk.2 fitted version of the Gunwale cap. Scrapped the first idea as it was rubbish. There will be more on items the foredeck later, so it won't look so bare when finished.


Pic. 2158 Sides sanded flat for the fendering to be added much later.


Pic. 2148 Hatch cover with sliding bottom so that people going down into the Fwd. Cabin don't hit their heads.


Pic. 2168 is the kit that I made for the Louvre Door leading to the Fwd. Cabin.   Enjoyed that bit.


Pic  2182 The Louver Door almost finished, just needs some more sanding before varnishing. The slats are not glued at this stage because it would have been a nightmare the remove any excess glue that got onto them.
As the slats are removable, it will make the frame very easy to clean up any excess glue, the slats will be the last parts fitted and they will automatically become glued by the varnish due to the very snug fit into the slots.  Enjoyed that bit also

Good Afternoon.


Progress on the Flybridge, just in it's rough embryonic stage at the moment, but gives some idea what it will look like.

The construction of the main body is by shaping round a 6mm ply bottom jig and for ease of bending and lightness I used the sandwich method consisting of 3 layers, the inner and outer layers are of 2mm lite ply with a 3mm balsa centre core. The jig was cut away after the laminating glue had set.
I also used the balsa middle layer to make it easier to route out the slot for the wind/spray deflector, which will be tinted after final shaping.

After making the steering wheel, which will be painted later, I have started on the twin lever throttle lever assy based on the Morse pattern. I don't know yet as to the instrument arrangement as that will be dictated by the throttle position next to the wheel.

Some pictures.

Thanks for the reply David.


My Op. keeps being cancelled due to CV19, understandable I suppose, there must be thousands of people in the same boat.


Re the Flybridge, much more work to do to it yet, it will get better tho' and the bending was an absolute pig to get right.


Here is a photo of the Morse type engine controller, quite pleased with it and looks o.k from a distance. ;)

Well I recognise the Morse Teleflex unit from a previous life, looks appropriate and in good proportion to me.


Thanks for the offer of the instrument panels, great timing as I had in mind to start looking at the Aquarama dash detail.  So yes please, would you send a PDF..?


And the delay...  Well just hoping it's manageable and gives you building time...

Some pictures of the progress made so far on the S/Fisherman, put on hold now as I need to start work on finishing the Biggish Aquarama.


Most of the work has been done inside the cabin, which I'm reasonably happy with so far.


When starting this build I was determined not to spend any money on it and just use up the stuff that I already had in the shed, with the exception of carbon fibre and a few bearings. The donor kit that I received as a gift has not furnished me with very many usable parts, particularly the wood which was dreadful.


I haven't fathomed out how to insert descriptive text between each picture so picture number with description first then pictures.


2287 and 2296 show the jig for making the cabin floor/hatches, not quite finished yet.
2288 my unusually tidy work bench.
2280/81 is the table assembly.


The rest of the pictures show that my very messy W/Bench can produce some half tidy results.

Hi Stew.


I made the table pedistal on my little lathe and the Brass dash dials were some that I already had, bought from Model Boat Bits,( best place as they don't charge for postage).
I would have liked to have them Chrome plated but the cost of decent hard chroming these days quite prohibiting. I did try spraying them satin black which looked quite good but it was far too easy to scratch, despite using a acid etching primer. So I settled for the Brass.
The actual dial faces were printed from my  PC into glossy photo paper.


If you want some let me have your email address and I'll send you  an A4 sheet of mixed designs and sizes.

A little more work recently, mostly on the inside.


Upholstery all but complete along with the Dash and it hasn't turned out too bad, also engine control's finished but still need the 2 ignition/ engine starters which I haven't yet fathomed. The size of the Range has been reduced slightly.

Thanks for that David, I really appreciate and value your opinion, although, with hindsight I think it could have been better, but it will have to do.


Unfortunately, I only get about 2 or 3 hrs. per week building time now and it seems that by the time I remember where I last left off most of the time has gone.


Hence, that is the reason for the lack of progress on both hulls.

At last a little more work on the boat.


Flying bridge painted and permanently fitted, but still some more to be done there, also, the Rx fitted with the 2 antennae correctly aligned. along with 2 fans that are controlled from the Tx.  The pictures show all so far.


I need to glaze the cabin next using 1mm TPEG and fit the F/Bridge spray deflector, just waiting for the tint film to arrive. I would have liked a subtle Blue but can't find any so have gone for 70% smoked, should be o.k. PTEG is very easy to use as it's very flexible and and easy to cut, no need for heating to shape.

At first I began to doubt it's looks but now that it's progressing I'm beginning to like it.
The pictures show it as very White but it is in fact a light Cream, not so much "in you face" in natural light.
The hull sides down to the chine will be an unusual colour, but I think it will be good with double Black boot topping which will be reproduced around the bottom of the flying bridge.
That should calm down the expance of the Cream, hopefully  :-) .

More progress on the build following a shortish lay off, so, here are a few photos showing the state of play so far.


I have modified the bow roller making a new roller and fitted it lower down to make the anchor more secure, also, made the winch controls which would be foot controls, Red for raise and Green to lower. The winch isn't permanently fitted yet nor is the anchor chain. I was intending to make a chain lock between the bow roller and winch but decided that was going to be too fiddly.


The cabin windows are glazed now and tinted to allow 75% of light to pass thru', I would have preferred a light green but couldn't find a suitable film that suited.


The 2 Blue Plastazote shapes will be fore deck mattresses when covered and stitched with the off white vinyl as in the cabin, I may yet tweak the shape at the front.

Superb detailing work. Window tint looks just right to me too, good contrast with the surrounding white, but clear enough not to hide the interior detailing.


Upholstery looking really good too.  I see it appeared in the thread without too much fanfare, looks to me like the same thin faux leather used on the Aquaramas. And looks like you've managed to achieve the appearance of piping, with great shaping of the seats / padding.  Is this a shaped balsa core, thin foam, then the faux leather, maybe the thin foam stitched to the faux leather to give the cushioning / padding effect..?


Its one of those tasks that I'm putting off as I don't have it clear in my mind how best to do it...
Best regards
David.

Good Afternoon all.

Thanks madwelchman,Rich, David and Stuw for the kind words, much appreciated.

David, the 2 seats on pedestals have shaped medium Balsa cores, then covered with a fairly soft synthetic wadding about 20mm thick but it can be easily crushed down to suit, no idea what it's called, but I think it's packing material, here's a picture, maybe someone could identify it. I doubt that it could impossible to sew it to the Vinyl tho'

I've experimented with many ways to achieve a decent cushioning/padding effect but I now only use 3mm Plastazote and a soldering iron to get the effect that I was looking for, all the upholstery in the big Riva and is done using that method as is all the upholstery in this one, with the exception of the 2 chairs on pedestals.
Sewing the foam to the Vinyl I believe would be very tricky due to the need to achieve an even ark from one line of sewing to the next, repeatedly, but you are a very resourceful man and it wouldn't surprise me if you did it. Have a go and see how it turns out, maybe it will work.

Mike.

As I stated earlier in the blog, I have little interest in the sailing of the boats that I build, but do derive satisfaction from the building, particularly wooden ones I do try to make them reasonably well.


My skill with metal, unfortunately, isn't that good but you can only do your best of course.


Off topic now, here are a some pictures of some bits of furniture that I made a while ago, a pair of corner cabinets,(one shown), a book case and 1 open corner cabinet, all from English Oak. These are the only things that I've ever made that I was totally pleased with, (the wife chose the contents, not me). ;) ;) .

Maybe mill a piece of nylon, then heat and clamp to conform it to the windscreen curve.


Just in case, I was thinking a bowden cable, inner bared through the housing, wiper clamped to the inner. Do same with second unit. Bring ends back to a 360 capable servo, and both ends to attach to one arm. That you give the motion needed...  just a thought...  :-))

Hello.


Build so far, unusually, managed to get a little more time this week, so I've tried to make the most of it.


The photos show the fore deck and sun bathing upholstered area, no sewing or cushioning this time due to not wanting any stitching holes that could let in water.
I did make some with stitched cushioning but didn't like it at all so it was scrapped. All of the photos are showing everything just laid in place, nothing fixed yet.


Have made an AIS touch screen unit which looks reasonable where it's to be fitted. It's showing the Solent.
It will be painted the some colour as the winch and bow roller. Also, the Morse throttles and dials in place, just need a few switches to finish it off.


Could't resist adding the, "Moody Photo". 1 more photo shows the flying bridge. The spray deflector allowed only 40% light, the tint was just too dark, so, I've made a new one using allowing 75% of light,much better.


Due to the AIS display turning out reasonably, I may make a Sat Nav or Plotter, along with Radar, both for the Cabin.


I may have to add a communications antennae/domes gantry to house the domes and aerials, I would rather not have to but will give it a go later.


Mike.

Pleased to hear you've had some time on the boat this week. Lovely work, and yes I think an arch is going to be needed to take all the antenna...! But will it be chromed tube, or a solid unit..?


The cushions look great, the edges beautifully rounded. Any pointers how you got that look..?

Evening David.


I use occasionally a Proxxon HUZ universal holder screwed to the bench and a rounding cutter 29036, the base of the shape is 1.5mm Birch ply then covered with Plastazote 3mm. Then just set up the depth of cut and run the piece round it,(another good reason for using Plastazote). The difficult part is pulling the Vinyl around the piece neatly, particularly on the inside curve.
I would like the cutter set 29020, but can't justify the cost. The HUZ is a very handy piece of kit, I use it with a 50mm  sanding disc much more than router bits.


Look here for the sanding disc..... https://www.banggood.com/Effetool-BG0300-2-Inch-50mm-Hook-and-Loop-Sanding-Pad-3mm-Shank-with-60pcs-Sandpaper-p-1089070.html?utm_source=googleshopping&utm_medium=cpc_organic&gmcCountry=GB&utm_content=minha&utm_campaign=minha-gb-en-pc&currency=GBP&cur_warehouse=CN&createTmp=1&utm_source=googleshopping&utm_medium=cpc_bgs&utm_content=tanya&utm_campaign=tanya-ssc-gb-euw-all-0113&ad_id=491180619117&gclid=CjwKCAiA1uKMBhAGEiwAxzvX9ygZMiqqt4omGK8HsksKGyj9RLoKPpHRNaE0Fg6ZLBH-uhu0X-n3jRoCwqwQAvD_BwE

Hi.

Latest piece of work which will be the last until the Spring due to my having to winterise the machines and all metal parts in my little shed.
I don't have any heating in there and it's very cold so roll on warmer weather.


The pulpit top rail is 3.5mm x 1mtr brass which  was too short but the longest piece that I could get. As I needed a piece 1.25mtr long, I had to splice in a further 250mm which turned out quite well and didn't show. The joint was done using silver solder as will the upright stanchions.


The photos show the jig roughly shaped  and then the final shape, along with the 2.5mm stanchions which are milled to lay on the top rail snugly which will show no excess s/solder.


Twiddling my finger now until the better weather.


Mike.

Good Afternoon.


Pulpit completed now with the exceptions of cleaning up with wire wool then popped into a bath of ferric chloride for a minute or so. That will ensure that the paint will adhere tenaciously to the Brass and not suffer from chips and scratches or knocks.


The uprights plug into plastic pockets so that should the need arise, it will be easy to remove the whole assembly and then re fit it.
The hand rails on each side of the flying bridge are also removable and easily re-fitted should the need arrives.


The wooden blocks are used to set the height of the top rail and then removed, depth stops are then glued into the bottom of the pockets.
The fore deck subtly droops to the point of the bow, but the the height of the top rail will always be the same.


Finally, I have to thank Subculture for all of his advice regarding the etching process.


Some pictures.

Agreed, rails looking good Mike, a very good looking boat, what colour / finish are you planning for the rails..?  Interesting about the etching to prepare the brass.


Looking like it could be ready to see the water in spring...   :-))


Great to see progress.

Good evening David / Bob.

Having tried several test pieces of the ferric chloride on Brass, particularly the solution strengths and application times
I have settled upon 25% water added to the f/c with a dipped or brushed time of 45 seconds.
I then washed the item in soapy water, ( washing up liquid ), and when dry applied a coat of primer, not posh stuff, just cheap and cheerful.
After a couple of hours drying indoors I tried to scrape it off, not a chance, the only way to remove it was by very brutal scraping with a scalpel, so no problems.  The primer then only needs light sanding before a top coat.

The colour that I want is s/steel which is the preferred metal for full size for pull pits, railings, ladders etc. as chrome would very quickly rust in water, particularly salt water.

I have looked at the data / application sheets of several, "etching primer", manufacturers/ retailers. Not one of them say that they will be suitable for Brass or Copper. The f/c method does work and at a very low price.

Also, should the primer need to be removed for any any reason then soaking in cellulose thinners easily removes it, but, the f/c etching process is still in place as it has left millions of microscopic dimples and scaring therefore will still be ready for use.

Mike.

Good Evening.


Have made a small amount of progress on the F/Bridge which I have modified yet again since the last posts.


Have painted the side hand rails, which turned out not too badly, gone are the days now of me paying for hard chrome plating).
The Ferric Chloride etching process has worked better than I had hoped, no chance of it coming off.
Should it ever be necessary to remove it for some reason it will need to be sanded off, scraping won't work, either that or drop the piece into a Gun Wash bath.


The spray deflector has been tinted and pertinently fitted and white piping around the top.


The dash has been simplified and the Mahogany had 4 coats of varnish then matted when dry. I will probably add the small Depth/Speed display as there is plenty of
space without adding clutter. Next thing is to make is the ladder up to the F/Bridge and hand rails.

The hull and deck need painting but the weather isn't warm enough to complete that so that is for the future.

Some pictures.

Mike.

Afternoon Mike


That chrome effect is looking good and very acceptable to me. The price of hard chroming was indeed eye watering for my Riva, looks nice, but at a cost...


The detailing is coming together very nicely, hope the improving weather lets you spend more time with the boats.


Very best regards
David.

Evening David.

I am quite pleased with the paint. I never intended it to look like Chrome, more akin to Stainless Steel really.

The weather is perking up a little now which has allowed me to put on the deck final coat at last. That leaves the side colour and the bottom to do, plus the cheat line.
The Riva needs a final coat of varnish and the White bottom. All of the deck furniture is made and trial fitted but still in the raw state. As I have no intentions of
 
Chroming the metal parts I think that will be about as far as I go with it.
The S/Fisherman will be finished fairly soon, when I make the ladder system and F/Bridge simple upholstery. The ladder system is going to be quite challenging  as it

is more than just for going up/down. That could prolong things somewhat, plus, I keep changing my mind about things all the while and have to make new bits.

As there are no building plans, as far as I know, for the Flying Dolphin, I have no idea as to what to build next, there isn't anything else that I like.

Keep well you and yours.

Mike.

Lovely to see more progress Mike. I was interested in what paint you used for the stainless steel look. Sprayed on? What type?
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on April 21, 2022, 08:34:56 am
Morning Stew.


The paint is Jenolite Original Chrome Paint..... https://jenolite.com/product/chrome-paint-aerosol-400ml/ (https://jenolite.com/product/chrome-paint-aerosol-400ml/)    £11.99 inc. delivery. Use very thin coats as it doesn't like heavy coats, 2 light coats are usually enough, allowing 24 hrs between coats.

It's very important to etch the metal first, Ferric Chloride for Brass or Copper or Jenolite Universal Etch Primer for Steel / Aluminium, same price.

https://jenolite.com/product/chrome-paint-aerosol-400ml/ (https://jenolite.com/product/chrome-paint-aerosol-400ml/)

If you have a QD store in your area then they have a version at a far less price. It's Paint Factory Colour It, almost as good as the Jenolite, same etching applies.

Hope that helps.

Mike.

Good Afternoon.


A little more progress on the build at last. Nothing is fitted permanently, just laid in place to see how they look.


Not sure about the foredeck upholstery tho', can't decide if I like it or not.


The anchor winch is Kevlar, virtually no weight and have added 2 louvre vents for feeding the internal fans for below deck cooling.


Also, the F/Bridge spray deflector is permanently fitted and White split rubber tube added just to finish off


Some pictures.


Mike.

Great to see the build progress Mike, lovely workmanship.  The upholstery looks exceptional, that's the area I've found most challenging.


Best regards

Good morning David.


I would ideally like to finish the hull painting but the weather is still too cold, as I have to do it outside, maybe next month !


The biggest and most difficult thing so far is the ladder system and seating for the F/Bridge, it has to be removeable along with the cabin.


I have one or two ideas, but I think there will be an awful lot of trial and error involved.


Mike.
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on June 16, 2022, 03:05:34 pm
Still building, but at a snails pace, I only get an hour here and there if I'm lucky <:( .
The photos show ... 58 pilot seat,  57 seat back and bottom, 59 seat roughly in place but legs not made yet so block of wood used as to show eventual height.
60 ProgressonStb.handrail 61 Main ladder in place but steps not fitted in place yet. 62 Progress on inner handrail, lots of bending and re-enforcing yet.

I haven't worked out how to fix the wooden steps permanently place yet as all of the brass work will be painted Stainless Steel effect and may get marked, which I don't want of course, any ideas most welcome.

Mike

A little more progress at last.


Photo's showing the completion of the F/B metal work and Helmsman seat etc. The F/B can be lifted off in one unit in seconds, with the ladder being removable following the F/B


The ladder mock-up has a little more work to be done but the metal stainless effect painted uprights are still hardening hence the scrap Brass.


I will probably make a Valise type life raft that will fit behind the seat and maybe a locker or two.

Truly superb detailing..!  Loving the grab rails and their end fittings.


Will it see the water this summer..?

Hi David.

Thanks for the kind remarks, much appreciated.

I have an awful lot more work to do before it goes in the water as the hull sides and bottom are only primed awaiting the colours, also, several other bits and bobs to make.


It will be put in the bath first just to make sure that it's watertight and where to set the waterline and at my building pace that will be quite a while.

Alas, I don't think this year.

Mike.

Removable ladder almost complete now, only needs the treads matt varnishing.


To fit the Flying Bridge including the ladder, only takes less than a minute.


Achieved by the removal of 2 M1.5 x 7 c/s screws only. The reverse to fit.


Mike.

Hi.


Flying Bridge is finished now but I couldn't make a Valise type life raft bag, unfortunately way beyond my capabilities, so, it's now a canister type.
Next job is the final painting of the hull and fitting of the fendering, just waiting for good weather, temperature is fine but I need a calm day as the painting will be done outside.


Some photo's


Mike.

A few pictures showing the progress so far.

Our young grand children chose the hull colour which had to be the same as their pet Lizard, (Remi), who is bright Green.

I promised them that I would, so here it is !!

I think about 10% more should have it finished.

Mike.

Lizard green! Seems to work. Did you make those exhaust nozzles yourself from scratch? Like the look of them.
Title: Re: Fairey Huntsman aft cabin becomes a Sports Fisherman
Post by: ukmike on August 22, 2022, 11:38:14 pm
Good evening  Stew.


I made the exhausts with 10.5mm dia. S/S tube which I already had and blanked the inboard end then fitted a nipple in the end at an angle so that the water hit the tube
wall rather than have a jet of water squirting from the tube like water pistol jet.
The 2 flanges are made from Brass washers shaped and drilled 5 equidistant holes for fixing.

I fully expected that it wouldn't be very well received here. I must admit to being surprised.

Thanks for the comments, much appreciated.

The model is now finished, apart for some graphics on the transom and hull sides which will add an once or two.

The all up weight including batteries is 6.7 Kg (12.34 lbs). Quite pleased with that.

L0A 1.25 mtrs (49.2inches).

Beam 0.38 mtrs (15 inches)

I don't envisage any more builds at this time, unfortunately.

Its a lovely build, a beautiful piece of work Mike, when will you get it out on the water..?  It's going to be pretty impressive at that size.


Best regards
David.

I echo David's comments. First class build as usual.

Are you going to keep this one!

Post by: ukmike on September 07, 2022, 09:42:17 pm
Thanks for that David.

I'll complete the graphics shortly then take it down to our little pond to try it.

Chris.

If all goes well at the pond then it will be packed away as I have little interest in sailing my models.

At last, the build is finally finished following a little more additions.
I'm quite pleased with the result, didn't think I would be.
Just need a suitable lake or large pond to try it, as the one we have in Gorleston is not suitable.


Some photo's.
