I only got a little bit of work done today: I did most of the deburring work on the main spar and installed the majority of the aft tank nutplates. Last time I installed the tank nutplates while the wing skeleton was still assembled in the jig - that was stupid since I had to work upside-down under the flange. This time I took the wing apart and just flipped the spar over. I didn't take any pictures today.
All that's left to get the spar ready is the last of the deburring, dimpling, and a final coat of primer.
