Amazed I couldn't find this simple info here by search but I couldn't. I recently bought a Schaublin 102N-VM which came with some excess 3 jaw chucks that were obviously not meant for the Schaublin... two of them are Hardinge brand and one is NOS in the original box Buck Adjust Thru 5 inch, all with threaded backplates the same size...about 2 1/8 to 2 3/16" I would guess on the threaded nose they were meant to fit, TPI a mystery...anywhere from 10 to 25 my guess.
So, if ya got an HC with threaded spindle nose, what exactly is the spec on that nose ?
