Drilled the edge of the lower aft skin to the main spar caps. Ran out of 3/32 cleco's, so up-drilled the rib portion of the aft skin to #30, freeing up the 3/32 cleco's.
Flipped wing over so that the top was facing up. Marked the centerlines of the upper and lower surfaces of the forward ribs.
Dug out the remaining leading edge skin. Cleco'd it into position on the main spar. When I removed the right wing LE skin from the box two months ago, I noticed that there were two pretty noticible dimples right on the upper surface of the left wing leading edge. Rather than do any drilling today, I decided to remove the skin and attempt some repairs to smooth out the dimple. That will happen in a day or two.
