11. Glue the 1 /4" x 3/4" x 42" balsa leading
edge stick to the front of the ribs. Align the top of the
7. Glue ribs W2-W11 into place on the lower
spar with a drop of CA. Pin the rear of each rib to
the shim stick.
8. Use the dihedral gauge to obtain the
proper angle (6 degrees) of W1. Glue W1 into
place on the lower spar. Pin the rear of W1 to the
shim stock. Use a long straightedge to insure that
W1 is flat.
9. Glue the 1 /4" x 3/8" x 42" basswood top
spar to the ribs.
10. Cut a 3/8" x 3/4" x 24" balsa stick to the
correct length and glue it to the rear of W7-W10.
The ends are glued to W6 and W11. Glue the top
flush with the top edges of the ribs.
LE even with the tops of the ribs. Use a long metal
straightedge to get the LE as straight as possible.
IMPORTANT: Use a straightedge along the sides of
W1 and W11 to insure that they are straight and flat.
12. Glue the 3/32" x 3" x 24" balsa lower
trailing edge sheet to ribs W1 -W6 using aliphatic
resin. Use a long straightedge to insure that the ribs
are even and straight and that W1 remains flat.
13. Use a 3/32" x 4" x 30" balsa sheet to
prepare the shear webs. There is webbing from W2 to
W11 glued to the front of the spars and from W2 to
W7 glued to the rear of the spars. Start with the ribs
that are spaced the widest first. Trim and sand the
sheet to fit between the two ribs. Sand the bottom edge
of the sheet to fit the angle of the lower spar, then mark
and cut the sheet to the proper height. Continue
trimming, sanding and cutting the sheet for all of the
webbing. Be sure to remove any pins that will be
hidden by the webbing before gluing it into position.
NOTE: The sheeting provided is ample to prepare all
of the webs, but there is no extra material so
work carefully.
14. Prepare the 3/8" x 3/4" TE that you
installed in step 10 for sheeting. Carve and sand the
TE to blend with the top of ribs W6-W11. If you are
not a careful sander you may want to put some
masking tape on the tops of the ribs so that you
won't alter their shape.
15. Glue the 3/32" x 15/16" x 24" TE sheet
to the TE and ribs using aliphatic resin. Note that the
sheeting extends to W5 and is trimmed at an angle.
