First, does the transom get epoxied in place, or is the fillet on the inside the only thing that holds it in place?
Second, The 1"x3/4" pine cleats that go on the top of the bulkheads near the bow. If the fillets go in first they then need to be rounded to fit the contour of the fillets. Is there any reason they can't be epoxied in first, then the fillets can go around the cleats?
