OK, fibreglass hull & I needed a forward bulkhead to store/hide additional tanks... Cut out a cardboard Cornflakes packet fold in half & trim to size/fit. A little snip here & a little snip there... Getting close. Transpose it to 1/16" ply..A little whittle here & a little whittle there ...getting real close, time for the engineers blue ( I'm kidding.) OK, saw out the inspection hatch with a razor saw, laminate with dolls house (real mahogany) flooring strips by laying down epoxy & taping all the strips togther with clear Cellotape (using black epoxy that oozes between the "planks" simulating pitch.) Cut out a frame for the hatch using a picture frame box jig. Paint with yacht varnish for that nautical look...
A whole day gone.....
There must be an easier way....
