ZEO, that's what I was thinking, but wasn't sure and couldn't find any specs.
Turns out, I got one with a mount that's not even the D-# type. I'm in the process of converting the existing mount to a D1-5 6-pin or 3-pin.
Which brings me to another question regarding "D-type" mounts. As I was considering how to accomplish the comversion I want to, it occurred to me that the biggest challenge was going to be maintaining the TIR of the original chuck. Then as I comtemplated that more, it occurred to me that there must me 'something' about the nature of the "D-type" mount that compensates for at least a little (a few thousandths or so) 'slop' in the postion and 'wobble' of the mating pins. There is certainly a frew thousandths 'slop' in the movement of the pins of the various D1-5 6-pin devices I have. Yet they all 'sung up' VERY concentric with the lathe head. So my question now is:
Is there something about nature of the "D-type" connector that 'forces' concentricity between the chuck and the lathe head when the pins of the chuck are tightened in the lathe head?
Thanks,
