unused hole in bent strut plates is to inboard. Sand off rough edges of wing spar trailing edge to avoid damage to sail
fabric. Cut out forward part of box selections in trailing edge with hacksaw. Sand curved part of
fibreglass trailing edge
to remove wax. Test-fit trailing edge to aft wing frame. Apply approx. half a tube of Liquid Nails to curved portion of
trailing edge (one bead down the middle and one down each side approx. 1/2” from edge). Stand wing frame on
leading edge and secure. Place trailing edge on aft wing spar. Rotate trailing edge slightly toward bottom side of wing.
(Bent strut plates stick out of bottom). Put straight edge against bottom side of fwd wing spar, aft wing spar and aft
trailing edge so it touches all three. Using mylar packing tape secure trailing edge to aft wing spar. (Push trailing edge
away from straight edge approx. 1”. Attach end of tape to inside aft wing spar and pull up around top side of frame and
over trailing edge. Pull tape down very tightly until trailing edge touches straight edge again. Wrap once more to fine
tune. Move approx. one foot down spar and repeat until done. Sight down trailing edge for straightness). Allow to dry
for twelve hours before removing tape. Sand trailing edges smooth and round.
