Hi Rick, would you believe it is me yet again, I just thought you might like to check out my Harbour, as I have just put three boats in there, all with steam engines. Plus I was thinking if I where you which I am not but if I was. you will need to buy an oil lubricator for your engine, and Clevedon Steam has a lubricator with a throttle lever control valve attached to it, this would make a lot of sense. Question, can you silver solder as you will need to

PROPELLERS
Hi Rowen, I agree with John ๐
Unless you have your own brass foundry the best we can do is turn the hub on a lathe, pre
fabricate
the blades (making sure that they are identical form and weights!), cutting / milling slots into the hub and then solder - which is weakpoint Number 1! Then wonder why it runs rough and cavitates cos it's outa balance and uneven pitch๐ก
I suggest you leave it to the pros like Rabeosch who for about 15 bucks or so will give you a robust cast, balanced and highly polished scale or sports finished article.
Weigh up the hours you will spend fiddlin' about against the price of a decent pro job. Especially if you need two or three the same for one boat.
Only time I fiddle about is when I need small scale props for my plastic magic projects 1/72 down to 1/350! e.g. 4 for a carrier like Ark Royal or Enterprise at 1/350. There ain't nowt that small on the market.

LED Tug Mast Navigation Lights
Wow! Hobby Engineโs tugs are nearly identical to the WYEFORCE. in fact, as you mentioned in one of your prior posts, the Southamptonโs color scheme is very similar to the WYEFORCE as well. I measured the OAL of my Richardson & it comes up a little bit short of the โadvertisedโ length of 22โ. it actually measures 21-3/8โ or 1.781โ [0.543m]. Using the inverse of 1:36 yields the OAL of the full-size boat: 1.781โ x 36 = 64.12โ [19.54m], which is 1.12โ [0.34m] longer than the 19.2m OAL stated for the WYEFORCE on marinetraffic.com. The length difference isnโt surprising because the โas-builtโ dimensions of
fabricate
d steel ships, boats, barges, etc. can vary quite a bit from the original engineering design. The length stated for the WYEFORCE could be an estimate or events like ECOs (engineering change orders), field alterations & damage repairs could have affected the full-size tugโs OAL. in my 35 years as a mechanical/industrial designer I frequently dealt with machinery that varied from planned dimensions. Iโm not a rivet counter & I doubt that most R/C boaters are either. itโs all about having fun, right? if the model looks right, it is right.
Enough said.

H.M.S. BRAVE BORDERER
Once the rudder, propeller and shafts were installed, the position of the motors could be established. A light aluminium bracket to hold all three was
fabricate
d and bonded to the hull. Due to the high speed capability of the brushless motors, particular attention was paid to alignment. Also kept to the shortest prop. shafts that could be fitted to avoid whipping.
Although the motor type might change, whatever is best will require a sound electrical installation as the current requirements for each brushless motor could reach 50 Amps. Wired each motor and ESC separately with its own dedicated fuse to give the maximum system protection. There is an extra fuse section allocated for auxiliary circuits, such as a cooling water pump and lights.
Will try the original planned layout of 3 x 2835 motors with 30mm propellers and a 2S Li-Po battery first. Am hoping the reduced voltage will also make these motors more tractable.
For the test program the three ESCs will be each controlled from an individual Rx channel. Once the final layout is determined, a more sophisticated and flexible control system can be installed.
To minimize ballast, particularly around the stern, the battery will be housed as far into the bow as possible. After the test runs the final battery type, size and location can be established. To assess performance, hope to try both 2 and 3S Li-Po batteries.
Planning to reduce heat build up by fitting cooling water jackets to the motors, these are easiest to instal at this stage so the wiring or mounts are not disturbed in the future. Have not decided the layout for the water circuit yet, but this easily can be added later.
All that is needed now is the ice to melt off our local lakes so tests can commence.

A little progress...
Slow progress recently, partly due to snow(!) but also because I have had some engineering to catch up on. Anyway, I have cut and fitted but not completed shaping the bow and stern blocks, fitted the prop shaft and

Yes, the keel looks a bit of a mess in this area but I am going to cover the ply with mahogany veneer to match the planking when I have completed that, and of course it will all be painted below the water-line. I also made a rough cradle to keep the boat steady while working on it - to be replaced with a posh one when everything is done!

Prop Shaft Grease
Hi Roy
I agree well made prop shafts such as supplied by Raboesch are excellent.
Personally I make my own to scale and length as I have the materials and lathes with which to
fabricate
them.
My experience over many years is that over time the bearings and shafts wear and will require replacing at some time. I have used oiling tubes and stuffing boxes for best results, the latter make small leak repairs simple, but if the prop end bearing has worn it needs replacing.
Our last club sailing waters were saline and I had to replace the bearings in all the models I sailed there. I used to wash the model hulls after every sail but it didn't help. I use a thick oil in the tubes.

Plankingโฆpart 2
After a successful first attempt at planking the tow-hook deck I then did the same to the mid deck.
I placed a 5mm border of maple with mitred corners, but I stepped it out around the forward cabin access door so that the completed deck panel can be dropped and slid into place beneath the door threshold.
The planking was placed working out from the centre line to keep the spacing even, and when the CA had fully set the black plasticard โcaulkingโ was trimmed flush with a sharp chisel and the whole surface sanded smooth.
There is a small detail on this deck which is identified on the Vosper drawing as a โfuel tank soundingโ, a sort of dipstick access point I suppose.
This part is not supplied in the metal fittings kit so and I
fabricate
d this from a piece of 10mm brass tube with a plasticard insert to replicate the detail.
This was then painted metallic silver and let into the deck after cutting a 10mm diameter hole through the planking.
To cut this hole I used a short piece of 10mm thin wall brass tube with a sharp edge filed on its internal bore so that it acted as a sort of โcookie cutterโ and it produced a neat and accurately sized hole in the deck planking.
The โstepโ formed by the door and frame was painted to match the door and then the complete deck panel sprayed with several coats of satin lacquer for the final finish.
I'm getting the hang of this planking lark so confidence is high as I move on to tackle the far more challenging cockpit deck ๐ค

DAMEN STAN 4207
From the Damen sheer, lines and section drawings developed building plans.
Decided to use a traditional 'plank & frame' construction style for the hull, which should suite both the hard chine design and help minimize weight.
Most readers are familiar with this type of construction, so in future will only describe features introduced to recognize specific hull design details or those added to achieve lightness with a low centre of gravity.
The basic framework was straightforward; decided to build the hull frame and then fit the sheathing (between keel and chine) first. This would create a definite hull form where all the electrical equipment could be trial positioned and installed, but still allow reasonable access. The upper planking (from chine to deck) will be fitted once this is complete.
The Daman section and sheer plans show only a limited number of sections, in the interest of lightness, decided to build the hull framework using only bulkheads corresponding to each section. if the hull proved flimsy these could easily be increased.
Due to the shape of the keel laminated the rear portion using 1/8' ply and wood strips. As the hull has a definite sharper keel section towards the bow, eliminated the wood strips to achieve this.
Used ยผ' sq. bass wood strip for the deck level and chine strips and a rudimentary stiffness check of the frame showed a satisfactory result. The limited number of sections is probably assisted by the hull shape which is has a considerable length to beam ratio, with sections transitioning smoothly. Tried to use ยผ' balsa strips for the deck strips but found they were too brittle, even when soaked in ammonia. Decided the potential weigh saving was not worth the trouble and reverted to basswood.
All the hull section and keel assembly was

Sounds like you are nearly ready to spill the beans on your system.
Weight will always be a problem with this size of boat. The standard props are really far too big and will need a powerful motor to provide the power.
The original uses a reduction unit, possibly 3:1 but would have struggled with the Mighty Midget used.
If brushless is not your thing then there are some modern small and light brushed motors that would work with smaller props and could be powered by AA batteries (2300MaH). 12 v is easily obtained without too great a weight increase.
I am out all weekend displaying at a model show so no sailing this weekend ๐

Making a mould to
fabricate
a hull
Have not tried this method personally but do know others who have had success. I believe you may have yo cover the finished foam shape with some form of protection (parcel tape may work) otherwise your shape will dissolve before the resin sets.
Assuming you only require the one hull this may be th quickest method but I suspect you will need quite a bit of rubbing down to achieve the required finish.
If you are considering multiple copies your former is unlikely to survive the removal from the hull.The traditional way is to make a hull and prepare a mould (usually in two parts) and lay the fiberglass in the mould on top of a gel coat. Takes some time but the end result is repeatable.

University Project - Hull Fabrication So Far
HI guys, hope you all had a good Christmas and New Year!
Thought I would upload a few photos of the hull I formed over the holidays for my university project for you to see and give tips on etc. If you so wish.
For the project, we are asked to design and build our own RC RUDDERLESS BOAT. It was decided to use foam as the material for the hull as It Is cheap (we are students after all), and also very easy to mold to the desired shape.
A catamaran design was opted for also as we felt we would gain not only more stability, but load bearing and component space on the deck.
The hull took me around 2 days to complete, however this was mainly due to my sometimes unhealthy need for a cuppa.
The hull was
fabricate

The two sections are yet to be glued together. An acrylic-based coating Is to be donned, also a coat of paint for added protection against the water.
My one major concern Is water Ingress to the two motor housings via the hole where the shaft will protrude. How can I solve this problem?
Thanks again for all the help!

Our next step will be to design and

The Kortz nozzles seem like a great idea, however after discussion with our adviser, he feels it would defeat the purpose of directional control purely from the props.
We will be controlling it via normal RC control, however we feel if we have time that control via an everyday controller such as a WiI remote would be pretty smart and not too hard to accomplish ๐ !

Epoxy and glass cloth applied
Finally the hulls were ready for application of glass cloth and epoxy resin. Applied with a large spreader to Impregnate the cloth into the balsa hull. After the initial coat the hulls were rubbed down with fine wet and dry to remove surface blemishes. A coat of resin coloured black and thickened with a fine powder produced a very hard finish. The initial hull needed quite a bit of sanding and we used a large body repair sander to remove any blemishes, then rubbed flat with wet and dry and final coat applied again with the spreader. So far only one forward section is to this stage, but all hulls have the cloth and epoxy applied. Hopefully our technique Improved from the initial hull and less sanding will be required. The outer prop shafts have been fitted to the two rear hulls and the three remaining halves will be treated with coloured epoxy and filler. Still undecided about the plating.

Arun 52'' Scale Lifeboat
Still reworking the hull to correct the deck levels. Also worked on the deck surround by filling with P38 and sanding to shape. The original edging was about 4mm oversize. Rubber edging will finish the job. I now need to wet and dry the deck and fill minor Imperfections. Also the steps need rasing to meet the new deck level.
Have started on the mast detail. Drew a plan to size from the RNLI plans and working from actual photos of the real boat

d the mountings. I am presently working on the VHF aerial at the very top. I need to find some way to join the mast array, basically two H aerials at 90deg to each other. Soldering not quite right so am working on plastic (delrin) to make the joins. I Intend to make the whole mast/aerial array detachable from the open cockpit floor as this will make carrying so much easier. The picture shows the mast so far, I have not fixed the upper mast so alignment Is out.

d. I think the etched sheet has enough for one boat. I don't have any plans just enlarged pictures that I measure from as the rnlI plans vary in accuracy but are a lot better on the more modern boats where they are cad designed. do you have plans for 52-08 or a different model as they are all so different! I have sent you some pics waterlines and the top of the white is level with the bottom of the spray rails, I was only going on the rear picture you uploaded as to it's final position? I had a look today in b&q I like your idea of the kick boards and they also had some brass angle that I might use for the l shape brackets? Not sure why you cant get access to the build on 24/7it should unrestrict when you log in? you can always pm the admin they sort it pretty quickly! if you pm me your email address I can send you a file with the pics of 52-08 and the others I have.
