...My question is, how do I do this and not bind up the tool? There
was no
shoulder or step on the original part to prevent the washer side
from
being pressed against the jaw too hard. There were also no
antirotation
type patterns like star shapes, cut-outs or anything like that. Was
the
washer heat fit by chance? I can get this tool mostly up and running
the
ugly way, buy really want to know what they did at the factory.

I would have made some threads on the pin and used a thin nut.
Probably
hit the nut by the threads in several places with a sharp punch once
I
got the tension where I thought it was good. Thin lock nuts are hard
to source...

You may be able to put a thin shim in between the jaw and handle.
Maybe fork shaped. Then just peen over your "rivet". Then pull, work
out the shim and hope there is a bit of play.


You could set the rivet with its head supported, then place the tool
over a hole that doesn't support the head and tap the other end until
it's loose enough.
