Fibre glassing......the secret is, go to a friends house, use his workshop, then all the resin drips on his floor!
In all seriousness, on a big boat like this, its a two man job, as the resin goes off quite quick, and the cloth shrinks, pulls, and moves, its a horrible job, but worth doing as the wood is sealed once and for all, but there is a lot of work involved afterwards, sanding finishing etc, but before that, lets sort out the running gear, the interesting bit (feel free to join in, is there anybody there??
)
The motors are brushless, and have 5mm shafts, the reason is, the shafts are to be removed, and the propshaft will go straight into the motors, no couplings, no drive belts, gears etc, the ultimate direct drive, and two of them!
, it could be a failure (so the mounts have to be designed in a way we can change the setup easily) or could be a success, if so, I patent the idea! ha ha
Getting the shafts out was ok, as the motors we chose had removeable shafts, they are 800kv. The problem was getting the propshaft through the can, it was an interference fit, with a grub screw, any off centre enlarging of the hole would render this task a failure, everything needs to be dead straight and true
As a precaution, I have drilled and tapped another hole in the can, so two grubscrews hold it in place, I dread to think of the damage if the can spins off, they are outrunners!
A mount was made from brass, which is soldered to the propshaft outertube, it slides on, and withing this is a bearing. An oiler tube is fitted, I dont like grease, first test in the kitchen sink
