I knew the wing was a lot of drilling, but I got into it today. I broke apart the nose skins and cleaned up chips then installed and drilled the two nose ribs that were at the overlap points of the inboard/ center and center/ outboard overlaps. This was also the first time I to double check rib alignment with my center lines. Things looked good. I reassembled the skins and drilled spar and nose ribs holes. Notice in picture #2 that I marked my clecos in the index holes to keep me from driling the lower spar holes per the manual. What a work out for the compressor.
