Up early this morning. Windy and cold outside - mid teens on the temp! I started dimpling the bottom wing skins for both wings. I also rolled the skin down on the leading edge so it layes down once it's riveted. I also filed down the skins at the overlap so it layes flatter with the double layer of skins. Then it was all dimpling. My arms were hurtin', but I finished the left and right inboard panels and started on one of the outboards.
