What can I do for a motor pulley for my Madel A 9"? It is a 2 step, about 3 3/8" dia and 2 1/16" dia. for a 5/8" wide belt. I searched the web but can"t seem to find something that would work. I have a 5/8" motor shaft. If anyone have one that they would sell please let me know. I guess I could make one if all else fails. Thanks
