5. Slide the aileron into position, guiding the hinges
into the slots in the wing. With the aileron pressed tight
against the wing, remove the T-pins. Use a few small pieces
of low-tack tape to hold the aileron in position. Do not glue
the hinges until instructed to do so.
6. Prepare the three pinned hinges by applying light
machine oil to the hinge point. This will help prevent the
adhesive from entering the hinge and causing it to not move.
7. Insert the three hinges into the holes in the flap.
Test fit the flap to the wing. Position the hinges so the flap is
aligned with the wing and can move freely without binding.
8. Once satisfied with the fit, note the position of the
hinges. Remove the flap and hinges. Mix a small amount of
30-minute epoxy and glue each hinge into position in the flap
and wing. Use a toothpick to apply epoxy in both the holes
for the hinges and to the hinges themselves.
9. Place the flap and hinges back into position and use
low-tack tape and a small piece of plywood clamped to the
wing to keep the flap in position until the epoxy fully cures.
Use a paper towel and isopropyl alcohol to remove any
excess epoxy.
10. Once the epoxy has cured, remove the tape and
clamps. If any of the flap hinges (only the flap hinges)
appear to be loose, apply thin CA to the hinge where it enters
the flap and wing to complete the flap hinging process.
