Chapter 19

This is a very exciting chapter. We build the wings. Now when friends and family look at our progress there is no doubt that we are building an airplane. Before this people would ask "Are you sure it is a airplane?"

My wife and son help me most of the time. Here we are sanding the wing spar. We will bond the foam cores to the spar. The foam is held in place with tape and drywall screws. We used hot glue to hold tong depressors on the side of the spar. This will hold the cores centered on the spar.

Alex has fun with the scrap foam. He uses a hack saw to cut and drills with bits powered with his hand. He uses nails and drywall screws to hold the foam together.

We built the plans jigs to support the wing on the work table. I built in an aluminum I beam into the trailing edge of the jig. This will help keep the trailing edge straight.

I used steel yard sticks covered in tape clamped on top of the trailing edge. This trapped the fiberglass between the I-beam and the yard sticks.

Here you can see how I will attach the ailerons. I installed click bonds. I drilled a hole through the wing skins, then floxed the click bond in place. I glassed one ply of bid over the top of the click bond. I will hide it in the fill during finishing.

I purchased bearings from Infinity Aerospace for the wing roots. They bearings are very nice.

I drilled the holes through the wing spar and center section spar in my driveway. I had a few people stair, but things went well. I used a two foot level, a four foot level, and a water level to make sure everything was just right. I used bondo to attach boards to the top of the wing and spar to check alignment during the instillation in the plane. I drilled all 6 holes and installed the bushings without a problem.
