I describe the shop made tool post grinder that I can attach to other machine tools along with normal OD grinding metal lathe use.
This tool also has the important function of trueing lathe chuck jaws using an ID grinding spindle.
The tool post grinder can be attached to old style tool & cutter grinders for a tilting head function and internal grinding.
Somehow the video blipped out at the end, I was mentioning constructing another ID grinding spindle with a 3/8" Erickson or ER collet nose for added versatility.
