This morning I was able to complete the wiring installation. After lunch I deburred the leading edge skin then opened up 18 holes in skins 3 & 4 from 3.2 mm to 4.0 mm so they match the holes in rib 12. When that was complete, I primed skins 3, 4, 5 & 6. Now ready to commence adjusting rib flanges prior to installing the skins.
