3. Test-fi t both wing halves together with the wing joiner
and the pin. Make any adjustments necessary for a good fi t.
4. Mix approximately 1/2 oz. of 30-minute epoxy. Working
quickly, pour some epoxy into the spar cavities in both wings
and distribute with a wire or small dowel. Coat one end of
the joiner and insert it into one of the wing halves. Coat the
protruding end of the joiner and both ends of both wing halves.
Then, join them together and wipe away excess epoxy as it
squeezes out. Proceed quickly to the next step.
5. Use a small clamp to clamp the front of the wing together
at the tab and plenty of masking tape to tightly clamp the rest
of the wing together. Use the paper towel squares dampened
with denatured alcohol to wipe away excess epoxy as you
proceed. Allow the epoxy to fully harden before removing
the clamps and tape.
6. Carefully remove the tape after the epoxy has hardened.
Residual tape adhesive may be cleaned with naptha (lighter
fl uid). Areas of the covering that may have lifted from removing
the tape should be retightened with your covering iron.
