All four spars are substantially done except for some touch up painting. But there are a few rivets I'm only let's say 85% confident of. I have drilled and replaced quite a few already. Sometimes the 2nd attempt is not much better than the first. Although I think these structures are very strong, I don't want someone to say "you really ought to replace those rivets" at some later stage.

So while I wait for a visit from at least one persnickety EAA technical counselor, I'm marking everything which could conceivably be a problem and then get expert advice. I am improving but the main problem is deformation of the factory head. You really have to keep your eye on the ball.

The main goal is to get a thumbs up on airworthiness of the spars. Only then will I tear down my elevated spar bench.

In the meantime, I can do some more rivet replacing, touch up painting, organizing and clean up. The plan for reconfiguring the shop for initial wing assembly is starting to take shape.
