Yeah, I think before I get the bottom built that I will put a layer of glass over the entire door from the inside to stiffen it up.
Right now I’m working on galley flat fitment issues. Holy crap this thing just doesn’t want to go in. I’ve managed to chip a 1″ x 1″ chunk of the outer layer of plywood back, but it’s clean and being glued up now. This will never show. The problem is this was on the first try and I couldn’t get the flat anywhere near close to being installed. More muscle, sanding, and swearing will be applied tomorrow.
