I use as spinet caster mounted into a pin block scrap. This is used as a lever on another block and pressure is exerted upwards and the wheel rolls forwards. Even the stringing hook is pulled towards the termination in an effort not to make a bend in the speaking length. Every little bit helps. Jon Page Harwich Port, Cape Cod, Mass.
