Began work on the F-623 corner ribs - 1.5 hours

Now that everything was match drilled, I flipped the assembly and began to figure out the F-623 corner ribs. I need to trim these as they need a little extra TLC being that there are shared from the older non-drilled/raw RV-6 parts. Of course I want to be careful and not trim to much, so I took a conservative approach. Check three times, and mark.
