Today I finished dimpling the upper wing skins. I also filed and polished the edges of the bottom wing skins.
When I disassembled the left wing, I discovered that I had placed the lower wing walk flipped the wrong way. As a result, the whole panel ended up about 1/4" out of position and some of the holes got doubled. I ordered a small sheet of .025 2024-T3 from Aircraft Spruce to make a replacement.
