Look Ma, No Hands!
Hi - I am looking for a cone-shaped expander nut and accompanying threaded bolt for my Kelly bars. The stem is 74mm long and the inside diameter is 21 mm. I've been looking for a while so I'm thinking this isn't an easy part to find(?) If I have little chance of finding something to fit if someone could point me toward a machine shop which could make something I would be grateful. This is for a Racycle. Thanks for looking!
