Continued the aft wing ribs. Drilled all lighting holes with a fly-cutter and have started deburring with scoth brite pads, deburring tool and sandpaper on a rotery drum in the drill press (not in the order).
I dropped and broke the camera, so I took these with my Blackberry which seems to do better, except in picture three. Believe it or not, the holes are really round. I do not know why it looks elongated here. Could be the angle I too the picture.
