Tonight I continued outboard on the right wing's bottom skin. I started out by tying the skin back with the wing in the cradle. I ran out of reach less than half-way down the 4th rib (outboard wing walk rib). I then had Karen help me move the wing back to the rotating fixtures. I got about 3/4 the way through that one rib before knocking over my bin of AN426AD-3-3.5 rivets. That coupled with the fact that I didn't have the nuts tight enough and the wing rotated down, the aileron striking the edge of the wing cradle, and I called it a night before I did any more damage. GRRRR!!!!!
