Following second failure of my hot water cylinder I am in the process of fitting a new chintzy calorifier.
The old was a smaller version of a household cylinder, the new one is a neat plastic encased cylinder that sits on a formed flattened side, so it won't fit the original round bulkhead mounted shelf.
So I have taken the shelf out leaving the bare hull to mount to, and in the area concerned it forms the inside of the spray rails towards the front of the vee hull section. So I have compound changes in profile to mount to, with two distinctly flat but sloping surfaces most convenient to mount to.
I am planning to make a flat timber base from 35 x 60 timber, suitably planed and built up as necessary to form a level top surface for the tank to sit on, but I am scratching my head at how best to secure the base wooden sections to the hull itself. I cannot screw the wood down, so I need to properly secure the timbers. Glassing the members in is obvious, but I am concerned at using GRP resin in an enclosed space, or I could use some wide Velcro and bond this to the hull with epoxy glue, but will this be strong enough - I expect the tank full will weight ~ 25 kg - quite a lot of momentum there when crashing off a wave.
Ideas please.
How dangerous is breathing setting GRP resin in an enclosed space ?
