1. Sanded and cleaned the flanges of the elevator caps, and the corresponding insides of the aluminum skins. 2. Mixed up a batch of resin/flox and applied it to the mating surfaces of the caps and elevators. (This should help prevent the typical waviness you sometimes see between rivets on these types of fiberglass flight control caps.) 3. Clecoed the caps onto the elevators. 4. Rived the caps in place. Clamped the elevator skins in certain locations to optimize the fit of the caps. 5. Filled the rivet heads with SuperFil filler.
