I was able to get the top inboard skin and the wing for the left wing all ready to rivet. This included: deburring all the rivet holes, finishing the edges, making a cutout where the inboard and outboard skins overlap, cleaning everything and priming.
Next the outboard top skin will get the same treatment. Then I will be able to rivet the rest of the leading edge. Then Britt and I can start riveting the top skins on!
