Ok I'm back with another question, Thanks to all who answered my last question I have cut and milled bead and cove into over 400' of strip which came out pretty good.But I know I will need more. Now to the question... When placing end forms on to strongback (using 2"x4" plywood beam as in Nick's book.) I see that the strongback must be trimmed at the bottom to fit in the dimensions of the boat...My issue is when I put endforms on to strongback, the butt ends(toward middle of boat)on the top of the end form, does not match at the top the first form that slides onto the strongback.Its about a .5" off... In my case it is form 4 and form 14 that the heights do not match. Do I have to cut the strongback down on the top as well as the bottom. Or do I cut the endform.
