D 3. From one of the remaining 3/32" x 3/8" balsa sticks,
cut cross-braces for F-4 and F-5. Glue these cross-
braces to the formers with thin CA as shown on the
plan. Use only a few drops of glue to avoid excess
weight build-up.
MAKE THE FUSE SIDES
D D 5. From one of the remaining short 1/8" x 3/8" sticks,
cut the tail post to match the plan.
D D 6. Hold or pin the parts accurately in place on the
plan, then glue the middle and lower longerons to
the fuse side and to the tail post using thin CA.
D 1. Find the 1/8" die- cut balsa fuse sides and the
1/8" x 3/8" x 23-7/8" balsa sticks. Inspect the balsa
sticks and pick out the four straightest ones which
you will use for the middle and lower longerons.
D 2. Tape the fuse plan to your flat work surface, then
tape a piece of waxed paper over the fuse side view.
D D 3. Accurately position one of the 1/8" balsa fuse sides
on the plan and hold it firmly in place with a heavy
book or with "shot bags" (A handy shot bag can be
made by partially filling a sock with lead shot or
BB's).
D D 7. Cut a third 1/8" x 3/8" balsa stick to match the
upper longeron on the plan (the upper longeron
extends back to the rear edge of F-6), and glue it to
the fuse side and to the middle longeron.
D D 4. Lay the middle and lower "longerons" (1/8" x 3/8"
sticks) in place and draw a straight line at the front
of the tail post. Cut the longerons off at these lines
using a razor saw.
D 8. While the fuse side is still in place on the plan,
use a straightedge and a pen to mark the locations
of formers F-4, F-5 and F-6. (Skip this step when
building the second fuse side.)
D D 9. Sand the fuse side smooth using a T-bar sander
with 100 grit sandpaper.
D 10. Now repeat steps 3 - 7 and 9 to build another
identical fuse side.
D 11. Put the two fuse sides together and line them up
at the front and the bottom edges. Then check to
make sure they are exactly the same all the way
around. Sand the edges as necessary until the two
fuse sides match. It is especially important that the
overall length be the same, so sand the tail post as
necessary.
