I looked in the pile of fixtures I got with the Tormek. I got the SP650 stone grader, SVS-50 Multi-jig, SVH-320 planer blade jig, a couple of knife jigs, wood turner's kit, hand tool kit, and an older style truing jig, cannot find the number. So, I already have the truing jig. I will buy the original wheel and get learning. Thank you for the help.
