I need a knob for a 1/8" D-shaft (the shaft has a flat side for a set-screw).
Radio Shack sells knobs but only for 1/4" D-shafts.
Does anyone know of a store in the New York City area that has knobs for 1/8" D-shafts?
(Normally, I would just go and make my own, but I don't have a set of taps to thread a hole for the set-screw).
