In this session, I started by flattening the bend out of the doubler fork that will be used on the inboard edge of the rear spar. This part comes from the factory with a slight bend due to the punching process during manufacturing. Then I clecoed it into place on the rear spar and match drilled all of the couple dozen rivet holes in it. Then I mounted the rear spar on top of the ribs on the rest of the wing assembly with clecos, to prepare for the next steps.

What's next? There's some more match drilling I have to do, then some priming prep.
