Hello, I am currently working on the Empenage, specifically the Horizontal Stabilizer. I am riveting the skin to the rib/spar assembly. I am having a real tough time riveting the inboard section with the nose rib, forward spar, doubler plate, shim, and main rib come together. I was originally supposed to use AN470AD4, but after setting some really bad rivets, I ended up enlarging the hole trying to drill them out. Every time I use the rivet gun with the bucking bar on these rivets, the rivet always ends up bending or warping on the shop side. I am using a 3x rivet gun, set at 40psi. I've tried all different types of bucking bars, but am unable to set these rivets perfectly. I've also tried to use the Cleaveland Tools Hand Squeezer, but it doesn't seem to have enough leverage or reach to squeeze these things tight. All three holes are now different sizes: AD4, AD5, and AD6. I have not been able to work on the project for well over six months due to this roadblock. Please help!
