Brief Description: Strut Fairing 2
|
|
An additional three layers of fiberglass were then epoxied to the previously molded fairing, allowing the fairing to contour onto the wing surface. Carnuba wax and release agent were wiped onto the wing surface prior to applying these layers. Next, the wing surface fiberglass was trimmed back to a one inch lip. After that had hardened, I used a hole saw to cut a circle centered on the Avipro tie downs. Next, a 2-3/8 gate cap was used as a spherical mold, and three layers of fiberglass were layed over the cap on the inside of the fairing, so as to gain room for a tie down rope. Next, a layer of microballoons and epoxy were placed on the fairings, and sanded down. A couple coats of sandable primer were place and sanded down, and glazing compound was used in a few spots, this was followed by white primer. I also torqued the strut attach bolts.
Next, three 6-32 rivnuts were used on each wing to secure the fairing to the wing surface, and three 6-32 countersunk screws, tinnerman washers and locknuts were used to secure the trialing edge. I still have to put some weatherstripping on the fairing-to-wing junction, but it hasn't come in yet from McMaster's.
