Step 3.
Allow the epoxy to fully cure for at least 6 hours. When
cured, work each hinge throughout its full motion several times
using your hands. This will break free any epoxy that may have
found its way into the hinge joint. Move the hinge throughout its
full travel until no resistance is felt. This may take as many as
40 or 50 times.
Step 4.
Mix 1 ounce of 30-minute epoxy. Using a syringe or
toothpick, place a sufficient amount of epoxy in each of the hinge
pockets in one aileron half.
Step 5.
Carefully install the aileron on the wing, making sure
the hinges are inserted in their respective hinge pockets. Press
the aileron and wing together such that less than a

line gap exists between the aileron and wing. The bevels should
virtually touch. Using a paper towel and rubbing alcohol, wipe
away any visible epoxy around the hinges.
Step 6.
Double-check the hinge gap and allow the epoxy to
fully cure for at least 6 hours. Now is a good time to epoxy the
hinges on the other aileron half using the same techniques.
Step 7.
When fully cured, move each control surface
throughout its travel range several times to break away any epoxy
in the hinge. Be sure to deflect the surface fully.
