D 2. From the 1/4" x 1/4" x 24" balsa sticks, cut stringers
to fit from former (E) to former (J). Use medium CA to glue
the stringers into the slots of formers (E), (N), (P) and (Q).
Be sure they are flush with the outside edge of former (J).
Use a sanding bar to sand the end of the stringers flush
with the front of former (E).
D 5. Center the tail wheel bracket on the aft end of the
bottom rear plate. The tail gear wire should be spaced
1/32" away from the rear plate. Mark the three mounting
holes and drill a 5/64" pilot hole at each mark. Attach the
tail gear to the rear plate with three #6 x 1/2" sheet
metal screws.
D 3. Center the 3/8" x 2-1/4" x 24" balsa turtledeck top on
top of formers (N), (P), (Q) and (J) and against the back of
former (E). Glue in place. Use a sanding bar to sand the
turtledeck top flush with the aft side of former (J). Use a
razor plane and a long sanding bar to shape the turtledeck
top flush with the edges of formers (N), (P) and (Q).
D 6. From a 1/4" x 1/4" x 36" balsa stick, cut a stringer to
fit in the center notch of the formers that run from former
(D) to the tail wheel bracket. Sand the bottom of the
stringer at an angle so that it is at the same height as the
tail wheel bracket base. Use thin CA to glue the stringer to
the formers and the bottom rear deck. Save the pieces you
cut from the 36" balsa stringer.
D 4. Position the die-cut 1/8" plywood formers (D), (R),
(S), (T) and (U) perpendicular to the bottom rear plate. Glue
in place with thin CA.
U 7. Use thin CA to glue 1/4" x 1/4" x 36" balsa stringers
into the notches on each side of the center stringer. Sand
the bottom of the stringers at an angle so that they are at
the same height as the tail wheel bracket base. Use thin
CA to glue the stringer to the formers and the bottom rear
deck. Glue 1/4" x 1/4" x 30" basswood stringers in the
corners of the formers with thin CA. Use 1/4" x 1/4" x 24"
balsa sticks for the bottom stringer on each side. Blend
this stringer into the bottom rear deck just past former (U).
D 8. Remove the tail wheel bracket. Cut a strip of 320-grit
sandpaper 2" wide x 11" long. Hold the ends of the
sandpaper on each side of the fuselage and work it back
and forth over the stringers to remove the sharp edges. Do
not oversand the stingers - just remove the sharp edges.
