Brief Description: Right Wing - Aft root rib - more pics
At first I only removed rib #1, so to get to the holes in the brackets I used an angle drill to get the first couple of holes in the front and the back of the root rib. With cleco's in place I then took off rib #2 and could then drill the rest of the holes using a 12" drill bit. They flex, so you can hold the drill off center, and hold the shaft of the drill bit between your fingers to bend it perpendicular to the bracket. Fingers are fine. Not enough heat to hurt a mosquito.
Up-drilling the root rib (I was just posing, so didn't have the drill perpendicular)
