Derek and I began the task of riveting the vStab skin to the center rib. This was very tricky and since this is the first real part of our plane where the rivets and the job we do will be visible forever, I was more than a little concerned. In the end it went quite well. Derek (8) did both bucking bar and rivet gun work and the result, though just 6 rivets in 60 minutes, looks nearly flawless.
