Lisa helped me get the 707 rib in place and I was able to rivet the rest on my own. I set the pressure regulator for 45-50, using the 3x gun, mushroom head, and the tungsten bucking bar. This worked very well. I could turn the pressure higher and go a little faster but for now I like the control offered by the lower pressure.
I also found out that the microfiber shop clothes that I got act alomst like velco when laid ontop of the MDF. This makes it very easy to lay down a protective surface to work on.
Note, the rivet on the right that is popped up. It was fixed by the follow up work on the 12th
