Is there a way to accurately machine rubber with a lathe or some type of tool? I want to reproduce(replace) a motor pulley for a vintage machine. It is just a circular rubber piece with a tapered outer surface molded around a metal bushing and secured to a 5/16" shaft of the motor by a rolled pin. The metal bushing can be replaced by the correct size tube with outside threads and the rubber part can be secured around this tube using 2 thin nuts and 2 washers to sort of sandwich it. I need the circular rubber part to be accurately shaped and sized to work in my application. It is about 1" bottom diameter and 3/4" top diameter. The thickness of the rubber piece is 1/2". Any suggestion is highly appreciated.
