Started to Rivet the VS Spar - 3 hours

Frustration!! I started to rivet the VS rear spar today. Things did not go as well as I hoped.

I ended up having real issues with getting rivets set with the squeezer. Many of my rivets on the brackets where folding over! I'd drill them out, only to have it happen again. I find drilling out rivets extremely nerve racking as there is such little room for error. The easier part for me is to drill the machined head, but getting the shop head and the rivet shaft out is really tough without scraping the work underneath. I also found it extremely difficult to set the rivets that are located at the bottom brackets as the rivets are extremely close to the vertical portions of the bracket. After some time, i noticed that some of my troubles came as I was using the rivets as called out on the plans. Many of them were just slightly over the 1.5 dia rule of thumb and I noticed that if I trimmed them down ever so slightly with the rivet cutter (So that they fit perfectly with the rivet guage) my chances of successfully setting them with the squeezer dramatically improved.  I decided to stop for the night and get some opinions at the EAA meeting tomorrow.
