Installing Ca hinges

After cutting the slots for the CA hinges, mark a center line on each side of each hinge with a crayon. Now, insert a t-pin or pin through the middle of the crayon mark. Drill a small 1/16" to 1/8" hole in the center of your hinge slots on on both surfaces (this will help the CA wick deeper into the surface). Insert the hinge into the control surface and then into the trailing edge. Apply 5 to 6 drops of thin CA to top side and then to the bottom side of the hinge. The pin will keep the hinge centered so you get an adequate amount of hinge in each surface. The crayon line will prevent CA from hardening the hingle line to a point of brittle and thus alleviates hinge breaking.
