For sale is a Harig "Steptool" Relief Grinding Fixture, Serial No. 1663. Spindle nose accepts Hardinge 5C and 5ST collets. 1-1/16" Maximum diameter held by collet. Variable speed drive. Operates on 1/60/115V Single phase AC power. Comes with spin-type 5C collet closer, On / Off / Reverse switch, variable speed potentiometer, swivel base, (1) 55/64" 5ST collet and a standard 3-prong, 115V AC plug. NOTE: There is NO DRIVE BELT with this fixture. I have tested the motor, potentiometer and reversing switch, and everything seems to be in good working order. The spindle turns smoothly by hand, with a degree of resistance (it does not feel completely "free").
