Flattening transom skin before installing core.

I may not have kept in the loop about how you are using carriage bolts. If you intend to remove them and it sounds like it because you are taping and waxing them, you are loosing the ability to rotate them to make removal easier. When I used the plywood on the brace my aft sheet for my Seacast pour I through bolted from the plywood thru to the fwd fiberglass with slightly smaller hex head bolts through the engine mount holes with flat washers and rubber washers to prevent seepage. Also waxed the hex bolts. But rotating the bolts as well as tapping on them aided removal.
