Riveting the VS skin to the forward Spar

This pic shows the inside of the skin after most of the riveting of the skin to the forward spar has been completed. The right side of the VS skin is on the bottom, and the left side is on the top. This pic also shows rivets of the skin to the middle rib of the frame (VS707). The camera is looking forward from the back of the VS where the rear spar will go, once all of the forward skeleton is riveted in place. The rivets actually don't look to bad here. I used both of my tungsten bucking bars and the flush set in the rivet gun to set these rivets. It is quite the trick, because you have to slide your bucking hand, in this case my left hand, under the skin, and hold the rivet gun with the right hand. You have to buck the rivets mostly by feel, and by learning how to position your hand and fingers around the bucking bar under the skin, and then focusing on the correct position of the rivet gun on top of the skin. Definitely takes some practice to figure out how to do it correctly.
