Hey guys all these great videos have made me resume work on my Donzi, but I've hit a snag. I noticed that my f/b deck doubler seems too small. the directions say that the doubler s/b 1/16 ply x 1-3/4 x 10 (step 23). But this seems to be too small and the wrong shape for that part of the underside of the f/b. Anybody have any suggestions?
