Section 2: Joining the Wing Halves
Step 6.
Place one wing half right-side-up on a flat work surface.
Note:
Use wax paper underneath the wing center while the
epoxy is curing. With the wing lying flat on a surface
without any dihedral, apply more masking tape to the
wing center joint and recheck that the wing remains flat.
Also make sure the wing halves are properly aligned.
Allow the wing joint epoxy to cure completely (overnight).
Using an epoxy brush, smear a generous amount of epoxy into
the wing joiner cavity in the wing panel.
Step 7.
Coat one half of the wing joiner with epoxy on both
sides, up to the pencil line drawn in Step 1. Install the epoxy-
coated half of the wing joiner into the wing joiner cavity of the
wing panel up to the marked center line. Any spilled or excess
epoxy can be cleaned up with rubbing alcohol and paper towels.
Note:
Mix an additional 1-2 ounces of epoxy to complete
the wing joining process.
Step 8.
Apply a generous amount of epoxy into the wing joiner
cavity of the other wing panel.
Step 9.
Install a T-pin into the wing joiner at the center mark.
Next, apply epoxy to all sides of the exposed area of the wing
joiner and uniformly coat both wing roots with epoxy.
Step 10.
Carefully slide the two wing halves together and firmly
press, allowing the excess epoxy to run out. Make sure the wing
panels align properly. Wipe any excess epoxy away with rubbing
alcohol and paper towels. The plastic wing bag can be removed
from the wing halves after the epoxy has been applied.
Step 11.
Apply masking tape at the wing joint to hold the
wing halves together securely. Place the wing right-side-up on
a flat surface.
Step 12.
Allow the wing center joint to cure completely, then
remove the masking tape.
