Riveting the left side of the VS skin. Progress is a bit faster now, and I am not having to replace quite as many rivets as before. Getting in with the bucking bar to rivet the middle nose rib - and then apply sufficient pressure with the rivet gun to set the rivet head flush is still very awkward, and I had to replace three of them before I was satisfied. This also mared the alodine coating around the rivet heads, so it looks realy rough. However, the skin panel is still smooth, so it appears to be just a cosmetic issue, that will disapear when I paint.
