Section 1: Hinging The Aileron - Hangar 9 J-3 Piper Cub Assembly Manual

Section 1: Hinging The Ailerons
Parts Needed
Right wing panel with aileron and hinges
Left wing panel with aileron and hinges
Note: The control surfaces, including the ailerons, elevators
and rudder, are pre-hinged with the hinges installed, but the
hinges are not glued in place. It is imperative that you
properly adhere the hinges and ailerons in place per the steps
below using high quality thin CA.
1. Carefully remove the aileron from one of the wing panels.
Note the position of the hinges. The J-3 Piper Cub comes
with high quality CA-type hinges, which are manufactured
in the USA.
2. Replace the aileron, making sure the hinges slide in place.
Deflect the aileron and apply a few drops of thin CA glue
directly to the center of each of the hinges. The aileron's
front surface should lightly contact the wing during this
procedure. Ideally, when the hinge is glued in place, a
1/32" gap or less will be maintained throughout the length
of the aileron. The hinge is constructed of a special
material that allows the CA to wick or penetrate and
distribute throughout the hinge, securely bonding it to the
wood structure.
Tools And Adhesives Needed
Instant thin CA glue
CA remover/debonder
Paper towels
3. Turn the wing panel over and deflect the aileron in the
opposite direction and from the opposite side. Apply
several drops of thin CA glue to each aileron hinge,
making sure that the CA penetrates into both the aileron
and the wing.
4. Using CA remover/debonder and a paper towel, remove
any excess CA glue that may have accumulated on the
wing or in the aileron hinge area.
5. Repeat this process with the other wing panel, securely
hinging the aileron in place.
