❑ Slide the wing joiner into the wing panel until it bottoms out. Quickly remove any excess epoxy, using a paper towel and rubbing
alcohol, and allow the epoxy to set up before proceeding.
❑ After the epoxy has set up, test-fit both wing panels together again to double-check that they still fit together properly. Check the
leading and trailing edges, too. It's important that they be even with each other.
❑ Mix a generous amount of 5 minute epoxy and apply a thin layer to the exposed half of the wing joiner, the inside of the wing
joiner box in the second wing panel, and the entire surface of BOTH root ribs. Make sure to use enough epoxy to fill any gaps.

✦ It is of the utmost importance to the integrity of the wing center-section joint that you apply a generous amount
of epoxy to both root ribs and the wing joiner. Not using enough epoxy can result in wing failure during flight.
❑ Slide the two wing panels together and realign them. Quickly wipe away any excess epoxy, using a paper towel and rubbing
alcohol, and use pieces of masking tape to hold the two wing panels aligned until the epoxy fully cures.
STEP 3: CHECKING THE WING CENTER-SECTION JOINT
❑ Once the epoxy has fully cured, remove the masking tape and double-check the center-section joint. If any gaps are present,
mix a small quantity of 5 minute epoxy and carefully fill any remaining gaps.

✦ Do not omit this procedure. The wing panels should fit together tightly, but it's possible to have some small gaps
that appear after the epoxy has cured. To make the wing center-section joint as strong as possible, it's important to fill any gaps,
using 5 minute epoxy.

✦ Allow the C/A to dry completely before proceeding
or you may inadvertently glue the wing hold-down screws into the
fuselage.
The C/A will harden the threads in the plywood, preventing them from
stripping out over time.
