My wee red boat after a rub down and a file/sand on the steel keel. This morning I painted the red with HMG enamel and got the green mixed in the same make enamel by my wonderful chap at Kett's Auto Paints. The mast came in two parts, so I did a slight scarf and glued it. When the joint is well set, I'll make a splint and set it in prior to a rub down and a good waxing. The steel (tinplate) parts came with the predictable rust, but with my selection of scrapers and chisels made of broken and worn Swiss files I was able to scrape most of it off back to reasonable shiny steel. The out of shapeness needed only a clout with a cold chisel type of bodywork tool in the right places to restore it to original shape. Loops were filed to lose most of their rust, but not replaced. They'll be Vaselined as a form of anti rust, waterproofing. I have some new 1.3mm cord coming from Caldercraft. I just hope I can remember how it was rigged. I ain't great with knots. The sails were absolutely filthy with some sort of oil based grime, but my dear bride sorted them out with Vanish and a good hand wash. Pics of those tomorrow. I love this stuff.! Martin
Added a 60A ESC of Chinese origin, improved waterproofing, and modified the rudder water pickup. Repainted trim tab extension as while it sat in the test tank (AKA the bath) the water got into the wood and split the paint work car spray paint not as water proof as I had hoped. On the test I found it was pulling over 40Amps which is not what I want as this is a race boat with limited battery capacity so cut down propeller by filling of the lagging edge of the prop via a drimmel and a file, so now pulls under 30A at full throttle. At the pond I will check current and prop-sizes.
Just a thought Martin on the wherry sails , have you thought of using boot polish to colour the sail. As you probably know that the original wherry sail started of white and it was only the waterproofing treatment they used that turned the sails black. Ron
This time I will try to remember to put in the ‘source’ information on the bits and pieces I use........... In the most recent piece I should have included exciters/transducers are Dayton Audio DAEX 25VT -4, 4 Ohms – 20 Watt pair, obtained from Sound Imports Netherlands and very quickly as well. The sound unit is a Mtroniks Digisound 5M diesel sound, available all over the place. Now to look at where I am at. Exciters are in place as high up the Hull as possible, but remembering the Deck level. Used the adhesive pads as supplied after wiping that part of the Hull with Meths and Silicone adhesive to keep in place as well as using the wiring tidies from Modelsport Ltd., for the cabling. (Pic 1+2) Before I start the motor and controller wiring I changed the platform ‘up front’ (pic3) with a piece of thin ply which I have given a couple of coats of varnish to waterproof. Then I thought to myself “why am I waterproofing this when, if it gets that wet, it will have gone to the bottom and be useless anyway”! (Pics 4) However, the platform gives a little more choice in terms of layout of other components and my plan for them is not really settled yet. I am concerned about the stern and possible swamping, but it currently seems the best place for the upgraded battery. (Pic5 ) Whilst talking batteries, I have gone for a separate battery supply for the receiver and hope to use the Bec supply for running other less critical items. Also the fitting of the battery in the stern bay drew my attention to the rudder servo for a couple of reasons. First is I am still considering increasing the size of the rudders and I am assuming that will increase the strain on the servo. The servo supplied is a standard issue and not water resistant so I have gone for an upgrade as shown(Pic6) That gives torque increase of 17Kg/cm over the Hobby Engine S1040C and has metal gears, metal control arm and waterproof for 20grams extra weight. Second is the closeness to the new battery position. So I was going to alter the servo arm setup anyway and the new metal arm suits this well. Maybe my ‘tutors’ will consider all this to be a little ‘over the top’ but I do so enjoy messing......................... New Servo DS 3218 by AYANI from Amazon. (Pics 6/7 ) Following that distraction, back to the front end and the Motor/Mixer placing and wiring. Now a little time ago I drew a plan to see what could go where and it came out that most of the ‘bits’ would go in the front bay with motors to be wired once power was brought forward, followed by the Esc/Mixer. (Pic 8) At that time I bought a P94 dual esc/mixer from Action Electronics and got the 20 amp version to be on the safe side................. My ‘guardians’ did point out this was ‘over-kill’ but I had already got it. Now, when placing the unit on the mounting board I found that the heatsinks made it too high to fit in the Hull! So being a spoilt brat only child I ordered the 10 amp version and as usual it came very quickly from up here in Bangor. ( Will keep the other one for the next project............Happy Hunter??) Unboxed it and it looked just the same, heatsinks and all. (Pic 9/10 ) So at that moment there was a bit of a set-back so I rang Component Shop at Bangor, they said “take the heat sinks off and you have a P94 lite”! Such a simple answer and such a nice chap. (Pic 11 ) Now a quick 'measure up' before I have a glass of wine (Pic 12) and does it all fit...? Well it appears to at the moment! (Pic 13) Next time really going to screw down the components under the forward hatch and wire it up. NPJ
I picked up a 46" Huntsman yesterday, so i have the same sort of restoration as you have, but bigger 😕 First thing to sort is the "started" planning on the decking. There must be somewhere I can buy strips of timber to plank with to save making my own. And what does one use to represent the black interplank waterproofing ? Otherwise I have to take off the bits already glued on. Cheers guys, Dave W 😊
All of the above suggestion should work fine, but a good idea to remove as much H2O as possible after every sail, and leave hatches etc open at least over night, to allow for any remaining dampness to dissipate that may have by-passed the waterproof coating, Have a 1/24th scale Vosper Motor Torpedo boat, constructed using balsa with tissue cover, which is some 30-40 years old, hull still sound using the above mantra. 😎
Hi Colin I'm happy to see there's someone else how uses cascamite l thought l was the only one, everyone else seem to use PVA's. It is a great glue but not on wood that has been soaked in oil. Best of look with the restoration. Regards Dave
