Brief Description: Riveting the skins to the skeleton
Riveting the skins was pretty easy except for those last 2 holes on the top and bottom rib trailing ends (both sides). Just no room for the squeezer or any of my bucking bars.
My solution: I back-riveted them, and used my crow bar's blade end as an alternate means of transmitting the rivet gun's impact force onto the rivet shop end. The crow bar has a blade end narrow enough to wedge in atop the rivet shop end, and I just smacked the crow bar with the rivet gun. Slow and easy, check that the rivet isn't pushing through to the outside. In a few minutes I had an acceptable shop end.
As for the rest of the skin rivets, I set them all with my pneumatic squeezer. My 4 inch longeron yoke was able to reach back and set the forward-most rivets on the leading edges.
