Back to the main hull Have finally got the hull sprayed today with this heat it has been drying faster than I can spray it on 😄 Firstly the hull was sanded with a 200grit paper to sand of the shiny coating to give the paint something to key too. It has had three coats of undercoat sanded with 2500grít wet and dry paper between each coat.the undercoat used was Halfords rattle can plastic primer. Then the lower hull colour was sprayed on again three coats sanded with 2500grit paper between each coat.colour used was Halfords rattle can ford arctic blue. the top half of the hull was sprayed with two coats only with it being black plus I didn't have enough paint to give it a third coat😋 colour used was Halfords rattle can satin black. Finally the hull was sprayed with Halfords rattle can clear lacquer three coats sanded with 2500grit paper between each coat.
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 fabricated 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.
I already mentioned in another thread ("Any Clues") that three boats have been dumped in my workshop to see if I can find a buyer for any of them. 1) Caldercraft "Joffre" Tug, already built but in grave need of TLC with the propshaft tight and the rudder shaft too tight to move. The vessel is filthy dirty. 2) Billings "Le Pourquoi-pas", hull assembled with decks, remainder of kit & fittings look to be complete 3) Billings "Smit Nederland" Nr 528 - unstarted kit but does not have detail fittings I can post any of these boats and would appreciate a sensible offer for any of them - I do need the space to get on with my own work. Please PM me for any further information Regards Barry
"This is certainly NOThe the model of a Thames or Coastal barge hull" I had come to that conclusion. Researching typical twin masted vessels with that sort of beam (thereby ruling out most schooners) it could be a Brixham Trawler or some kind of ketch. One suggestion was a Moray Firth Scaffie but I need to go to one of the local museums to see if there is a model or a drawing. Interesting clue - the rudder post is carried above the deck. I guess half the fun is trying to see what I can make of it and then get it on the water.
Ships boat continued It's coming along now almost finished planking the sides just a couple of planks to fit and can then plank the stern. It's certainly been a learning curve doing my first clinker hull and at this size , there has been a few mistakes but that's modelling .
This is certainly NOThe the model of a Thames or Coastal barge hull The proportions are all wrong and it has a keel-a Thames/Coastal does not. Also the rudder is wrong for a Barge which .has the rudder hung from a stern post.
The vessels mentioned in my last post have now been dumped in my workshop so they are available if anybody is interested. Le Pourquoi-pas has been started (hull & deck) looks as if most fittings are there but the workmanship leaves something to be desired. Joffre is in need of a lot of work - it is built but filthy dirty and needs a lot of work plus the prop shaft is on the edge of being seized and rudder shaft is so stiff I daren't move it The Smit Nederland kit is complete and untouched BUT does not have the detail fittings. If anybody is interested please contact me direct regards Barry
The model is 1.48 scale scratch built on a fibreglass hull.Very detailed and accurate. Radio Controlled 2.4Ghz with working lights. She is 38 inches long For sale complete with the radio and batteries ready to sail.She is very weatherproof and can sail in rough conditions. The top is sealed on and released with four screws, no need to get inside to charge her up as there is a charging point at the top of the funnel. A display stand is also included I am asking £800. If you are interested you can come and have a look before committing yourself. email me direct on firstname.lastname@example.org
Hi Hacker I have a 650mm deep vee with an outboard motor setup, the standard brushless motor is a 28mm 3000kv on 2s 2650mah lipo. On full throttle it sits up on the prop with no hull on the water. Increase the battery size for a long run as you have decrease your weight and have 200grams to play with !!! Canabus
