17-3: Step9: Dimpled the remaining LE L-Wing skin. J-stiffener holes shown in second photo. Although difficult to see, these holes were larger than desired after drilling due to a malformed drill bit. It did not seem to cut just right and I thought it was just me. I had bought five of these together, #41, and all of them were suspect. Cheap construction, when back to some older bits that cut correctly which did not wallow out the hole. Lesson learned. Threw all five away. Can't rememeber where I got them. the dimpling of the hole still seamed ok as the skin holes were the one slightly larger and the J-stiffener holes on the back side were normal size. Rivets fit reasonably well.
