advice on re-core fuel cell hatch

[phatdaddy]

I did ridge, i had 6 five gallon buckets full of water, plus a couple of of battery cores and 100 lbs do lead ingots on it. I applied a thickened mixture of cabosil and epoxy on the hatch, wet out the ply and put it on the floor. Then stacked the weight on. Worked great. After that, a layer of 6oz cloth.

Solid as the deck of the kitty hawk now.

Exactly skunk. I was thinking about doing the squares again, but figured this was faster.

Worst part of the whole deal is my caulking.

LOL, cool. Weight will mash that plywood in nicely. Good job.
