22. Glue the 1/4" x 1" x 3-29/32" [6.4 x 25.4 x
99mm] basswood wing bolt plate in place between
the W-1 ribs and onto the doublers W-1B with
6-minute epoxy.
23. By now your landing gear rail assembly
should have cured. Drill a 5/32" [4mm] hole through
both of the landing gear rails and the torque blocks.
Drill from the side of the landing gear rail that has the
groove. As you drill, make sure you hold the drill at a
90 degree angle to the landing gear rail and that the
hole is centered in the torque block.
24. Use 6-minute epoxy to glue the landing gear
rail assembly to the slots in W-1 and W-2. Be sure that
you glue the torque block securely to W-1 when gluing
the rail in place. Do this for both sides of the wing.
25. Locate one of the 3/32" x 3" x 24" [2.4 x 76 x
610mm] balsa wing sheets. Cut it into four pieces
3/32" x 3/4" x 24" [2.4 x 19.1 x 610mm].
26. See the Hot Tip that follows, then glue one of the
3/32" x 3" x 24" [2.4 x 76 x 610mm] balsa sheets to
one of the 3/32" x 3/4" x 24" [2.4 x 19.1 x 610mm]
balsa sheets to make one 3-3/4" [95mm] sheet. Make
four sheets for the top and bottom LE wing sheeting.
WING SHEETING
A. Use a metal straightedge as a guide to trim
one edge of both sheets.
B. Use masking tape to tightly tape the two
sheets together joining the trimmed edges.

C. Turn the sheet over and apply weights on top of
the sheet to hold it flat. Apply thin CA sparingly to
the seam between the two pieces, quickly wiping
away excess CA with a paper towel as you proceed.
D. Turn the sheet over and remove the masking
tape, then apply thin CA to the seam the same
way you did for the other side.
E. Sand the sheet flat and smooth with your bar
sander and 150 grit sandpaper.
27. Test fit the wing skin sheeting. The sheeting
should join at the center of the rib W-1A and be
against the notch in the rib. Glue the wing skin
sheeting in place on top of the spar and against the
notch in the rib. When the glue has cured apply a bead
of glue to the top of each rib and along the sub LE. Pull
