Countersunk one hole I missed yesterday, then mounted the left leading edge, clecoing it in. Then I started on the tough rivets that attach the leading edge ribs to the main spar. I got most of them done, except for the outboard most rib, and a couple of rivets that were too tough to squeeze and will have to be bucked like the inboard most 4 ribs were. The toughest ones are done and I should finish this tomorrow.
