Its a union 5" 3 jaw. I saw it run on the lathe i got it from and it ran true on that lathe and cut beautifully.
I have cleaned the threads on both spindle and chuck. I measured 0.017-0.018" of wobble on the front face.
I am getting 0.002" lift on the front spindle bearing when i do the deflection test.
I have 2 other chucks, 5" 3 jaw cushman (jaws trashed) and 6" 4 jaw that the bodies run true on my spindle. Also collets run true
