21. Use a felt-tipped marker to mark the slot of the hinge on the wing.
22. Remove the aileron and hinges from the wing. Use a pin vise and
1/16-inch (1.5mm) drill bit to drill a hole at each mark. Drill the hole
1/4-inch (6mm) deep into the wood.
 Drilling this hole provides a tunnel for the CA to fully wick
into the hinge and surrounding surface. Failure to drill this
hole may result in a hinge that may not be glued properly.
23. Use a paper towel and isopropyl alcohol to remove any marks from
the wing and aileron. Fit the hinges and aileron back in position.
Apply thin CA to the top of each of the hinges. Make sure to fully
soak the hinges so the CA can wick into the hinge and bond to the
surrounding wood.
 Use thin CA so it wicks into the hinge. A thicker CA will
not wick into the hinge properly. Do not to allow the CA
to run over the covering on the wing and aileron.
24. Apply thin CA to the bottom of each of the hinges. Make sure to fully
soak the hinges so the CA can wick into the hinge and bond to the
surrounding wood.
25. Allow the CA to cure for 10 to 15 minutes. Gently pull on the fi xed
surface and control surface to make sure the hinges are glued
securely. If not, apply additional CA to secure each of the hinges.
