Oct 05, 2007· The chuck happened to be on the spindle when I took the picture. The first job I did with it, the job that nudged me into adapting it as a toolpost grinder, was making an ER-11 collet holder for the Unimat. I intend to use that for most small work. For larger wheels I will make some custom arbors that mount directly on the Unimat spindle.
