I have my new tank(155 gallon, 3'16 thick instead of OEM 1/8), rebuilt front and back bulk heads, new sole, painted bilge, new fuel lines, glued (5200) 3/16 UHMW strips to the bottom. All systems go. Slide tank into it's very pretty coffin where it should rest peacefully for the next 30+ years. Or so I thought.
Screeching halt yesterday, I have a rock from SB rear corner to front port corner between 3/8 (10mm) and 1/2 (13mm) inch. Now what to do? When I glued the strips on I turned it over and set it on the floor(pretty flat concrete floor) and let the glue wet out. Must be a high spot on the sole.
Shim it? Slide some 5200'd thinner UHMW under the high corners of the current UHMW strips and tab it?
Stabilize/Equalize it and tab it in like it was originally?
Foam it and forget it?
Boat is on a trailer.
Tank is of course empty. If I clamp one corner down and step on the high corner my 225# might flex it 1/16"? Can't really measure it with out help but visually it seems very little.
One problem with using the UHMW/starboad on fiberglass is it slides, like on roller skates.
As I posted above, it had been tabbed on the top of the tank to the stringers. I was thinking of using 5200 and adding aluminum strips/tabs to screw into the stringers with lag screws. Any other innovative ways to keep it from moving?
Regs say no more than 1/4" per side clearance, I might have a little more but the tank overall is no smaller than original(48 L-R 70" F-B). Might have 3/8 side.
