1. Draw a centerline on both sides of the wing joiner

as shown.

❏ ❏

2. Test fit the wing joiner in both wing panels by sliding

the joiner into the joiner cavity in the wing. The joiner must

slide in with little resistance up to the centerline drawn on

the joiner. Lightly sand the joiner edges, sides or ends if the

joiner will not fit in the cavity. Caution: A snug fit of the

joiner in the joiner cavity is desired. Do not sand the

joiner excessively.

❏

3. Test fit the wing panels together with the joiner in

position. They must fit flush against each other without any

gaps. If the panels will not fit together tightly, lightly sand the

joiner edges, sides or ends. Caution: The wing panels

should fit together without any gaps.

Note: When performing the following steps, be sure to use

a sufficient amount of epoxy to form a complete and solid

bond between the wing joiner and the wing halves. This is

the most important glue joint in the entire airplane.

Please read the following three steps before mixing any

epoxy. You must complete these steps within 20

minutes from the time you mix the epoxy.

❏

4. Mix 1/2 oz. [14ml] of 30-minute epoxy. Use a mixing

stick or epoxy brush to apply epoxy to all four sides of the

joiner cavity. Coat all surfaces of one half of the wing joiner

with 30-minute epoxy and place it in its corresponding joiner

cavity. Insert the joiner into the cavity up to the centerline

marked on the wing joiner. Be sure you are installing the

joiner to obtain the correct direction for the dihedral. Quickly

proceed to the next step.

❏

5. Apply epoxy inside the joiner cavity of the remaining

wing panel. Next, coat the wing root ribs on both panels.

Coat the other half of the joiner with 30-minute epoxy and

join the other wing. Quickly proceed to the next step.
