Place the control surface aileron, elevator or rudder against the wing, stabilizer or fin as appropriate.

Draw lines across the rear part of the surface. Extend the lines down the trailing edge spar as illustrated. If a Hinge Point Drill Jig is not available it will be necessary to draw a horizontal center line also.

Center the drill jig over the vertical line and drill the appropriate size hole to suit the hinge point. Inject glue into the hole before inserting the Hinge Point.

Any epoxy that does get around the knuckle can be cut away later with an xacto, it want stick if you oiled the knuckle. I do all the hinges on one side of the surface first. It is important for the hinge pin to be aligned the same depth into the surface as all of the other hinges. I usually split the pin or brad with the out most part of the bevel on the surface they are being inserted into. Let the hinges all lay over into the most deflected position this helps you get an ideal if they are folding at a 90 degree line to the surface they are in.

Now the fun part, putting on the other surface ie elevator or aileron. Dope up the hole the same way. Put a little less epoxy on the barb part of the hinge. Put the elevator down onto all of the hinges and insert about half down the hinge.

Check for epoxy being squeezed up out of the hole. If not add a little epoxy to the barb with a tooth pick. Push the surface down further. This is often what you get. Available hinge slotting guides do not resolve the problem because they are made from soft, flexible plastic. If the slot is not located properly on the first attempt, then more material must be cut away using a hobby knife so the hinge will align properly.
