you don't have to go through all that. install the ca hinges dry with equal amount of hinge material in the ail. and the wing. the gap should be the width of a t pin. after you have it where ya want it. using ONLY thin ca...place 3 drops on each hinge on top of the wing and 3 drops on each hinge on the bottom of the wing. the thin ca will wick into the slot and glue the hinge in np. if this is a trainer type plane there should be no need to pin the hinges. some guys do but i believe most don't.
sealing of the gap can be done in several ways...most use covering that matches your wing. just iron in a piece about 1/2 inch wide and the length of each aileron in the gap at bottom of wing. fully flex the aileron first then iron it in to keep it from binding.
