Finished spars by deburring and countersinking necessary rivet holes. There are a bunch of pieces that attach to the rear spar so some of the rivets wait until the other parts. It looks like a lot of missing rivets but they will be done later. Cleaned, primed and attached enforcement plates on the Left side rear spar. Right side will be easy and quick now that I have the empties figured out.
Cleaned with paint thinner and ready for primer
Primed and ready to go
