Joining the Wing Halves
Step 4. Mix approximately 1 ounce of 30-minute epoxy. Using
an epoxy brush, apply a generous amount of epoxy to the wing
joiner cavity of one wing panel.
Step 5. Completely coat one half of the wing joiner with epoxy
up to the centerline made in Step 1. Insert the epoxy-coated
side of the joiner into the wing joiner cavity up to the mark on
the joiner.
Step 6. Apply a generous amount of epoxy to the other wing
panel joiner cavity.
Step 7. Apply epoxy to the exposed portion of the wing joiner
and to both wing roots.

Step 8. Carefully slide both wing panels together. Firmly press
both halves together, allowing the epoxy to run out. Use alcohol
and paper towels wipe off the excess epoxy. Check to make sure
there are no visible gaps between the two wing panels.
Step 9. Use masking tape to securely hold both wing halves
together. Place the wing assembly back onto the flat work surface
(covered with wax paper), and check the dihedral again as in
Step 3.
Step 10. Double-check the wing center joint for any gaps and
allow the epoxy to cure overnight.
