I have a question on the transom, the manual says:
"Fiberglass the forward and top faces (but not the lower and back faces) of
the LVL pieces with 10- to 12-ounce biaxial fiberglass, optionally glassing
with 10-ounce woven fiberglass wet-on-wet to avoid having to fair the
biaxial after curing.
Is this done before laminating the lvl to the plywood transom?
To put this in context, the quote above refers to the LVL motor board on the transom, not the LVL stringers....
The instructions refer to glassing the LVL motor boards ('beams' in the drawing) prior to gluing them onto the transom. You will glass over the motor cut-out later, e.g. glass will overlap onto the aft face of the transom and onto the f'w'd face of the motor board.
Somewhat obviously, you could actually glass these in any order, and could even glass over the top of the motor cut-out when you glass the motor boards if you want extra glass there... not necessary though. Another option is to put the biax on the motor boards after they've been glued onto the transom and cured, nails/screws removed as necessary. This would allow you to fillet any gaps between the upper and lower motor boards and to transition any difference in height (with thickened epoxy) between the lower doublers and the motor boards ...then glass over the hole thing smoothly, and add 10-oz wet-on-wet and almost totally avoid fairing on the transom. The main thing is to a) have that biax on the motor boards, and b) have the minimum number of ounces on the transom, inside and out.
