Riveted the rear spar together. Started with the hand squeezer and that was extremely difficult. I see why people have bought pneumatic squeezers. Changed to the rivet gun and the job was no sweat. Could have used another set of hands though. Needed to drill out a couple rivets due movement smiles on the rivet head. Picked up a set of wooden squeeze clamps and they worked like a charm holding the spar stable while riveting.
