A stud in threaded connection with the larger diameter bore and carrying a relatively thin blade-like, clamping mandrel pin with serrated edges that extends into the smaller diameter bore and extends between adjacent folded ends of a polishing cloth disposed around the cylinder with the ends extending through the slot and across the smaller bore, and which functions to rigidly clamp the ends between the serrated edges and the wall of the smaller diameter bore when the stud and clamping mandrel pin are rotated by 90.degree.. A block with a bore for receiving the cylinder with polishing cloth thereon holding the members together during the clamping process and the block includes an angled slot for back-folding the ends of the polishing cloth.
