Scott I am trying to digest all of that.
What I did do is install the degree wheel while I was out and set up and zeroed a dial indicator.
I rotated the handle exactly 90 degrees and took a reading.
The indicator moved .0615 which is .001 off of 1/16 of an inch, it is coarse threads on the press so you cant expect too much .
What the degree wheel does do is magnify the movement on the handle.
Scott I dont have a lathe or milling machine, I do have a Miller Tig welder.
