Drilled the leading edge to the spar and all but the last rib.
As all holes are now match drilled, I countersunk all the skin and leading edge rivet locations on the main spar. Dimpled the rear spar and cleaned them up according to the building manual. Instead of doing by eye per Van's suggestion, I used the same microcage depth setting as for the main spar. It ended up pretty good, some were already deep enough.
The weather was not on my side have to wait with covering up the raw aluminum.
