The Drive Pulley

Drive Pulley

The belt grooves being turned in the face of the pulley. I had to grind up a cutter specially for this as they are half-round grooves. Spacing was taken care of by using the top slide to advance the cutter by an equal division of the face width.

The bore was then drilled and bored to fit the crankshaft nicely. Then it was mounted on a piece of scrap shaft and the back face was finished.
