Brief Description: F-704 BH - Drill F-633's. Part 1.
Thes F-633's need holes where X marks the spot. Image 1 is the top and image 2 is the bottom. Note the dimensions are not the same. I'll clamp it onto the spar viewing the cross through the thick spar flange and match drill both holes. This is not the way the instructions have you do it. See next entry.
