I am asking for help, some tribal knowledge. An answer to WTF am I doing to cause this.
I've seen this before when riveting thin sheet thicknesses, like two ribs together. Only happens with 1/8" rivets.
In this repeat case, I'm riveting a AD4-4 into two .025" sheets. (Not that it matters, but the rear seat assembly) Result is a rivet meeting MIL specs, but the sheets deform...essentially they peak upwards around the manufactured head of the rivet. Technique is I am using my C-frame to back rivet these.
In contrast last night I riveted the Front seat assembly, the difference on this case is that assembly has 1 part thick, the side angles. No deformation, perfect rivet, perfect overall result. Like this case when one of the two sheets is thick this never happens. But when two .025" or even slightly on two .032 thickness...I'll get deformation. Even with bucking bar technique too.
So, with two thin sheets, and a smaller length rivet, I get these deformations.
Side note: My gun is a new 3X US AT CO. I totally hate this gun as it hits way to many repetitions, even on AD3 rivets too. Is this gun, thus the excessive repetitions causing this. I have played with air pressures a lot. My experiments doesn't solve this chronic problem.
In past it wasn't a big deal. But this time the rivets are on a seat back...which someone will see, and I'll have to roll my eyes and explain my moron moment.
Anyone that has seen this, what did you figure out to remedy this.
