I have some money to buy a TIG or MIG welder to replace the fuel tank, make a combined bimini and solar panel rig, and probably deal with the bowsprit as well as miscellaneous hardware, so even though I only have a few hours experience with TIG and MIG I think I can cope. I think it will be worth it.
Does anyone have any ideas or experience on fuel tank design, and materials?
My engine is still in and I dont really desire taking it out, so a pair of joined 25 gall tanks is my approach because if I get the dimensions right they can fit in through the sail locker.
I was thinking aluminium might be easier to work but dont really know how thick or what to do about fittings, seems a bit of a weak point.
It is important because it might guide me to whether TIG or MIG is more appropriate, so any comments at all are welcome
Timely. I'm halfway through replacing the tanks in Skookum. Decided not to join them below fuel level, going with a 6-port valve for draw/return and a 3-way fill valve. Based off the drawings posted on the site, I subtracted an inch in length and 1/2 inch in width for the replacements, because it was tough to get two mockups in place at the original dimensions. Can live with a bit less fuel. Attached specs, and a photo showing the start of lining the wood cradle with PVC standoff shims to prevent corrosion. Hardware store window trim. I also replaced the fuel level view port in the cockpit sole with a 5" ss access port, through which I'll be able to reach the valves to choose port or starboard tank. Today am fabricating a little panel out of starboard to fit in the old engine stop indented panel at shin height to stbd of helm. It will have a single fuel gauge, rocker switch to choose P/S tank signal, and the engine stop pull unit for my Yanmar. Hope this helps.
