Re-drilled new flap ribs - 5 hours

I had rush shipped new flap ribs so that I could carry on with a big build this long weekend.So one of the big jobs was to re-assemble the flaps and begin the process of match drilling the parts. Learning from past experience. It takes a lot of care not to enlarge a hole that has already been match drilled. So it was a lengthy process, but in the end it worked out well.

I also deburred and dimpled all of the new rib holes (with the proper dies this time) and it turned out perfect.
