Tonight I riveted the rest of the VS rear spar and the forward spar together. Everything came out pretty well. I had only a few little smiles when riveting the universals. They were very small however, and I was able to buff them out easily. I also got some experience riveting with the rivet gun and the bucking bar around the rudder attach brackets. I had some difficulties with squaring the bucking bar at first, and ended up drilling out a few rivets. However, thanks to my rivet drill-out tool and all the practice I got drilling the rivets in my old trashed VS spar, it was easy.
