Today was a major and long day. My solid Rivet "cup" inserts for my Rivet Set arrived and I could Solid rivet the Center Main Spar that I finished, deburred, and primed last week. The set worked as advertised and I only put a "smile" on one of the rivets that I now must drill out and replace (and it was a very small "smile" indeed...but it's still coming out.
I then set up and drilled the Wing Main Spar - right, deburred, primed all of the parts for it.
