Brief Description: Begin assembling parts and adding to bottom skin
Assembled the landing gear doubler assembly and then back riveted to the bottom skin. I had an unusual problem as the larger #4 flush rivets would sit perfectly in the dimples but when I would set the rivet it would not longer be flush by quite a bit. After drilling out many bad rivets it occurred to me that the problem was the higher power setting on the rivet gun to set the #4 rivets was causing the whole assembly and the back riveting plate to bounce and that would cause the poor rivet sets. I took the long and heavy special bucking bar for the elevators and put that on top of the back rivet plate and the extra weight did the trick, no more bouncing and no more bad rivets. The bad side is that you had to be very, very careful back riveting on that narrow bar as it would be easy to sip off the edge and medd us the parts.
Did some deburring and priming of the last few parts to finish this section which will be needed in the next cupe sessions.
