Today, after our monthly EAA meeting, a friend from our chapter came over to see what progress I had made so far. While Matt was here he notice a few rivets on the main spar that were not driven to specification and needed to be replaces. It was very good to have another experienced builder look over my work as this just shows how easy it can be to overlook something like this. Thanks Matt!
I did some more deburring and removed a couple washers on the rear spar attach plate.
