D 1. Glue the die-cut 1/8" plywood instrument panel to
TTF. It should be perpendicular to TTF.
around the firewall and instrument panel and mark where it
crosses the centerline of the 1/4" square stringer. Cut the
sheet on the line you marked.
D 2. Cut three stringers from the 1/4" x 1/4" x 36" balsa
stick to fit between the firewall and the instrument panel.
Refer to the cross-section for the exact positioning of the
two bottom stringers. Notice they are slightly angled
inward. Glue the stringers in position with medium CA.
D 5. Pull the sheet back into position and glue it in place.
D 3. Cut two 5-1/2" lengths from the 3/32" x 4" x 12" balsa
sheet to make the forward fuse deck sheeting. The rear
corner of the sheet will have to be beveled where it
contacts the cabin side. With medium CA, glue one piece
to the right fuselage side and bottom stringer only.
D 6. Apply the other sheet in the same manner as
described above. Trim the sheeting flush with the back of
the instrument panel and the front of the fuselage sides.
D 4. Wet the outside of the sheet with water and let it soak
in for a few minutes. Firmly, yet carefully, pull the sheet
D 1. Slide two 36" long pushrod tubes through the slots
in the rear of fuselage, then through formers F5, F4, and
F3. Cut and position the tubes so they extend past the aft
edge of the slots 1/4" and approximately 5" past the front of
former F3 to allow for trimming later. Remove and scuff the
outside of the tubes with 150-grit sandpaper so the glue
will adhere to them. Reinstall the tubes and securely glue
them in position to each former and the fuselage sides.
