I have a Craftsman Model 113.213842 drill press. The spindle pulley nut has come off. It is an odd nut. It is round with no flats. It has 2 slots 180 degrees apart. The parts diagram calls it a ring nut. It looks like I need a spanner wrench, but I can’t find one this size. It is left handed threads. I would order a regular hex nut but don’t know the size. Can anyone help?
