Today's task - fiberglass the fairing below the Windscreen.
Began by repositioning the fine line tape so that it would be close to the final paint line. Used the 7" radius template to deternime where the tape should fall. Thoroughly sanded the Black flox, the upper fwd fuse skin, and the plexi to ensure adhesion. Mixed up some black micro to fill some voids & depressions left from the flox, and also trowled some around the pop-rivited 'fingers' to make a fillet around their edges for bettwe fiberglass bonding. then began the process of doing the lay-ups. I used 3 plys of 6 oz as I couldn't find 9 oz cloth. I wetted out 3 plys on plastic sheet, using a plastic squeege to get good penetration and consistent epoxy, then put another layer of plastic sheet above the lay-up, again used the squeege to remove excess epoxy to the edges, and then cut strips of the appropriate width using a roller blade cutter. when applying the lay-up's I did them in 2 pieces, one 32-34 " long and the other 35-38". I butted both pieces together and alternated the butt joint to 2" off the center for every other layer. It's a pretty messy affair, because you need to use your hands to ensure there are no air bubbles between lay-up's and inevitably you end up snagging a glass strand, which tends to pull out of the bundle and creats a few wild 'threads'. The 'fingers' created some bumps that carried through until the last couple of layers. Will have to count on Super-Fil to fair everything even. I probablly ended up with too much glass on each end by the doors, which will have to be sanded when cured.
