Instruction Manual

23. Locate and remove the 1/16" thick W-19A (PLY) horn plate
doublers from their die-cut sheet. Glue in place on top of
horn plate W-19 (PLY), as shown on the plans. Locate and
remove 4 of the G-2, 3/32" balsa gussets and glue these in
place into each corner of each aileron as shown on the plans.
24. Using a small sanding block and medium-to-coarse sandpaper,
lightly sand the protruding tops of the aileron spar and aileron
L.E. stock down to the airfoil level of the wing. These should
blend with the cap strips to create the finished airfoil (refer
to wing/aileron cross-section on the plans).
25. Prepare the aileron bellcrank mounting trays W-20 (PLY) by
first drilling them per the dimensions given on the plans with
a No. 45 (.082") drill bit. Mount the 90° aileron bellcranks
to the trays as shown on the plans. These should work freely
but without "slop". Epoxy the trays into place on the AT-1
supports in the W-6/W-7 rib bay.
26. Remove wing panels from the building board. Inspect each
panel carefully to be sure of good glue joints, etc. Now is the
time to clean-up each panel to prepare them for finishing.
Glue all the remaining gussets, G-1, G-2 and G-3 in place as
shown.
27. Carefully block-up each panel upside down on the building
board. Be sure that the panels are firmly pinned and blocked
in place and that they are truly flat. Prepare the bottom for-
ward 1/8" x 1/4" x 36" sheeting spar by first trial fitting it in
place into the slots in the ribs. Relieve any rib slot that might
force this spar out of true. Score the spar just outboard of
rib W-9 and lightly crack it. Bevel the tip end of the spar to
fit flush with the wingtip, as shown on the plans and glue the
spar into place. Secure with pins and allow to dry.
