|Individual boat station frame
Boat frame on table being
test fitted. Note the plastic sheeting, which is used to protect
table and plans from the epoxy. The center framework is clamped
to table to set the reference line for the floor gusset, which
is a very critical dimension. Align this piece with a try square
The floor gusset rests on the motor stringers. If this is set
up properly, then the frame alignment and initial fairing will
go smoothly. Remember, errors here are magnified at the chine
and sheer by greater than 2:1.
Accuracy here pays off in greatly reduced fairing effort later.
The floor gussets are Fir marine plywood. Next time, I would
recommend Okoume instead of the fir for ease of working and finishing.
The chine gussets are Okoume marine plywood. The Fir has superior
rot resistance, but has a MUCH greater tendency to chip and delaminate,
whether in initial shaping or even after coating with epoxy.
