I remade 6-ZU-1-3 and 6-ZU-1-4 today. 1-3 is the nose rib angle, and I had carelessly misdrilled one so I was one short. Regarding 1-4, the rib angle, I simply misplaced it. I'm sure I'll find it later, but I can't spare the time to tear apart my shop for one part. The bending and trimming of these parts took about 40 minutes. The rest of the time was spent moving the wing outside, reinstalling and uninstalling the bending brake, then replacing the wing. I hope I don't have to do that again.
