JOIN THE WING PANELS
1. Locate the three plywood wing joiner pieces. Glue the
three pieces together using epoxy. Note that the joiner has
a slight “V” shape that will give the wing a small amount of
dihedral when assembled. The point of the “V” shape is the
bottom of the joiner. Wipe away any excess epoxy with a
cloth dampened with denatured alcohol and use clamps to
hold the pieces together while the epoxy cures. Be sure that
the joiner pieces are glued so the edges are fl ush with each
other. Mark a centerline on the assembled wing joiner. The
centerline is used to confi rm that the wing joiner fi ts halfway
into each wing panel.
2. Read all of step 3 and dry fi t the parts together to ensure
a proper fi t before gluing. Sand the wing joiner or root ribs if
necessary to achieve the correct fi t. The root ribs should join
together tightly with no gaps. When satisfi ed, glue the anti-
rotation pin halfway into the hole of one of the wing panels
as shown.
3. Use a mixing stick or something similar to coat the
inside of the wing joiner pockets of both wing panels with
30-minute epoxy. Thoroughly coat one half of the wing joiner
with 30-minute epoxy and insert it into the joiner pocket of
one wing panel with the bottom of the “V” shape pointing to
the underside of the wing. Coat the root ribs of both wing
panels and the protruding end of the wing joiner with epoxy.
Slide the wing panels together and use tape to hold them
tight while the epoxy cures. Wipe away any excess epoxy
with denatured alcohol.
4. Trim the covering from the holes in the plywood wing
bolt plate as shown. Position the wing bolt plate over the
wing bolt holes on the underside of the wing and use a felt-
tip pen to trace around it.
