BUILD THE FORMERS
Q 1. Unroll the plan. Re-roll the plan inside out
to make it lie flat. Wax paper or Great Planes
Plan Protector" placed over the plan will
prevent glue from sticking to the plan.
Q 2. Place the 3/16" x 1" x 14" balsa stick over
the portion of the plan marked leading edge
joiner, and line up the back edge of the stick
with the straight line. Draw two angled lines
where you will cut this stick. There are two
dashed lines on the plan to help in drawing the
lines in the correct location. Remove the stick
from the plan and cut the stick along the lines
using a hobby knife or razor saw. Straighten
and square the cut edges with a sanding block.
Trim the ends slightly to match the length
shown on the plan.
Q 3. Pin the stab forward center into position on
the plan. Test fit the 3/16" x 2" x 3" balsa stab
center into place. There should be no gaps
between the center and forward pieces. After
fitting, pin and glue the center to the forward
using medium CA.
Q 4. Use two 3/16" x 3/8" x 36" balsa sticks to
build the outside framework of the stabilizer.
Start by cutting and placing the longest piece
first, working until you are placing the shortest
(end) pieces. Glue each piece together using
medium CA as you proceed.
BUILDING HINT:
If you are unfamiliar with "Built-up"
construction, we have found that the
following method is very easy and accurate.
A. Position an uncut stick directly over the
plan and pin it in place.
B. Mark each side of the stick where it ends
or butts with another part.
C. Remove the stick from the building
surface and flip it over. Draw a line
between the marks you made previously
using a straightedge.
D. Using a razor saw, cut as close to the line
as possible. Then, with your sanding block,
true-up the ends to the line. Flip the part
over and pin back in place over the plan.
0 5. Cut and install the stab bracing using a
3/16" x 3/16" x 36" balsa stick. Note: It is best to
start with the straight pieces, then go to the
angled pieces. The alignment of each piece to
the plan is not critical, just as long as it is close
and fits snugly into position. Use the remaining
wood from the stab forward center for the
gussets in the corners.
