Great Planes Piper J-3 Cub 60 Kit - GPMA0162 - Manual (Page 36)

D 4. The R1 fin leading edge must be securely glued to the
aft fuselage deck and the stabilizer deck. Add thick CA where
necessary, then glue the top deck former TF4 in position.
D 5. Glue the remaining die-cut 1/8" balsa TF3, TF2 and
TF1 turtle deck formers to the aft fuselage top.
D 3. From the remaining 1/4" square stock, cut two more
1" pieces and two 4" pieces. On each of the four one inch
pieces, put a mark 1/4" from each end and cut a bevel as
shown in the sketch.
D 6. Cut the 3/16" x 22" hardwood dowels to fit from the
front edge of former F3 to the aft edge of former TF4, then
glue them in place.
D 4. Glue two diagonally cut sticks on each 4" stringer. Be
sure to make a right and a left side. These pushrod exits
will support the covering.
D 5. Slide a 4-40 x 36" threaded end pushrod wire into
the pushrod tubes with three inches protruding outside the
pushrod tubes.
D 1. From two 1/4" x 1/4" x 36" balsa sticks, cut two
34-1/4" aft fuselage side stringers and two 1" sticks. Cut
two 7-1/4" forward fuselage side stringers from the
remainder of the 1/4" x 1/4" x 36" balsa stick used earlier
for the nose deck stringers.
D 2. Use a straightedge to mark a line along the fuselage
sides where the side stringers are to be located, taking
measurements from the plan.
D 6. Temporarily pin a stringer to the fuselage side and
position the previously constructed pushrod exit on the
stringer, centered on the pushrod. Glue the pushrod exit to
the stringer but not to the fuselage. Build a pushrod exit for
the other side.
