Good idea tarheel..if it's simple enough, I would set the cap back on her, do your braces, then remove the cap again for transom as you will need it out for that chore. . Transom first...maybe lay a piece of old plywood on the hull back there to give you brace to work off of while you prep/grind/scrape/etc. Once you get the transom tabbed in, I'd put the cap back on, as jig suggested I think, then work on the deck, including further demo, grinding, etc. Also, depending on your deck height, you might consider cutting your foam access holes BEFORE installing deck. This is especially important if you don't have a whole lot of under deck/bilge area. I was too nervous that I would just let her rip & hole saw all the way down thru the hull. I cut a few after I put csm on the underside, but before install/tabbing in. Once I got it tabbed in, I was ready to pour foam. Just save your pucks(label if need be)..
