I finished up the rib dimpling on the left wing upper/outboard panel along with the countersinking for both the top skin and the leading edge rivet lines. Went pretty fast. I dimpled all of the rear spar to skin holes, except for where the aileron attach doubles ran, I needed a second opinion on that since the plans weren't too specific. I called my buddy Mike Cencula as he is past this point with his wings to see what he did and it looks like I just dimple and go (maybe alittle machine countersinking as necessary). Short but productive session.
Countersinking the spar for the skin rivets.
Dimpling the rear spar for the skin rivets.
Machine countersinking done. I even did the leading edge skin rivet holes for this panel.
