10. Make sure the hinge can move freely and that the pin is aligned
properly before the epoxy sets! When you are satisfied with the
results set the surface aside so that the epoxy will pool around the
rear of the hinge. When you are comfortable with this process you
should be able to do one side of a surface per batch of epoxy.
Repeat the process to attach the surfaces to each wing. There
should be as little gap as possible while still allowing maximum
movement of the control surface.
11. As a final step before setting the wing aside to dry, do a final
cleaning of the hinge knuckles with a paper towel soaked with
denatured alcohol or acetone to remove any epoxy residue. If you
find any of the hinges are stiff after drying, apply a drop of acetone
to each hinge with a Q-tip and move the surface back and forth
several times to loosen it up. As a final step I typically apply a
couple drops of silicone lubricant to each hinge. This is available
at most home improvement and hardware stores. DO NOT USE A
PETROLEUM BASED LUBRICANT AS IT WILL DEGRADE THE
INTEGRITY OF THE NYLON HINGE!
