D D 8 Use medium CA to glue the die-cut 1/8" balsa
gusset to rib R-5 and the shear web Sand the TE flush
with rib R-5 Then glue the die-cut 1/8" balsa rib caps to
ribs R-5 and R-6.
D D 3 Wet the sheet once more Carefully lift the sheet
away from the ribs Then apply a bead of medium or thick
CA to the top of each rib Working quickly, pull the sheet
back toward the main spar as you press it down to the
ribs and spar Glue the aft edge of the sheeting to the
main spar with thin CA Use masking tape T-pins or
weights to hold the sheet to the ribs until the CA cures
D D 1 Fit a 3/32" x 3" x 36" balsa sheet to the top of the
wing panel by first sanding a bevel on the front edge of
the sheet to match the angle of the leading edge of the
wing Before you glue the LE sheet in position, remove
the T-pins from the front jig tabs Reinstall the T-pins
through the ribs right behind the bottom main spar
Note: Save all leftover 3/32" sheeting for use on the
fuselage.
D D 2 Wet the outside of the LE sheet so it will bend
more easily Hint: A 50/50 mix of water and either alcohol
or ammonia helps soften the wood fibers so the sheet is
even easier to bend Position the front of the sheet
against the LE and flush with the side of rib R-6 Glue it in
position with thin CA.
D D 4 Lightly sand the TE area so that the TE and aft
balsa spar are flush with the top of the ribs From a 3/32"
x 3" x 36" balsa sheet, cut a TE sheet 17-1/4" long Save
the cut off piece for the bottom TE Glue the sheet to the
TE and ribs so that it overhangs the balsa rib cap, at rib
R-5, by 1/32" and is flush with the front edge of the aft
balsa spar Do not trim the sheet at the TE.
