Section 2: Joining the Wing Halves

Parts Needed

• Right and left wing halves

• Wing joiner

Tools and Adhesives Needed

• 30-minute epoxy

• Ruler

• Felt-tipped pen or pencil

• Rubbing alcohol

• Paper towels

• Wax paper

Step 1

Locate the wing joiner. Using a ruler and felt-tipped pen or pencil,

measure and mark the exact center of the joiner as shown.

Step 2

Trial ﬁt the wing joiner into one of the wing panels. It should

insert smoothly up to the line marked in Step 1. If the ﬁt is too

tight, it may be necessary to lightly sand the wing joiner. Carefully

slide the other wing panel onto the joiner until the two panels

meet. The wing panels should ﬁt together with no gaps on either

the top or the bottom of the wing.

Step 3

Use masking tape to hold the wing halves together while you

check for the correct dihedral angle. Place the wing on a large ﬂat

surface, with one wing panel resting ﬂat on the surface the tip of

the opposite wing panel should be 5" from the ﬂat surface. When

you are satisﬁed with the dihedral, separate the wings and remove

the joiner.

Note: Read through the remaining steps of this section

before proceeding to glue the wing panels together.

Hint: It is extremely important to use plenty of epoxy when

joining the wing panels together. It will also be helpful to

use wax paper under the wing center joint to avoid gluing

the wing to your worktop.

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

mark made in Step 1. Insert the epoxy coated side of the joiner

into the joiner cavity up to the mark.
