John, Seems like you have at least one good leg on each of the pulleys from which to determine radius. Radius times 2 plus hub plus outer thickness of pulley, no?

One is distorted and the other has disintegrated. It was suggested to me to do away with the double and quadruple pulleys and use a 1/2†V belt. I don’t want to change the ratios so I am hoping someone can give me the dimensions that the replacement pulleys should be. Thank you.
