skmetal7, That would work IF you can find a belt that has a round tooth contour and you put the round holes on the correct pitch diameter and pitch that matched the tooth spacing of the belt. However, all the readily available belts that I'm aware of are of propietary shaped teeth and they are not round. They are compound blended angles with blended radii designed to mimic the involute gear teeth. Unless the application of your pulley is slow speed and limited use, the pulley (sprocket) would eat the belt alive. Snoop around a bit, there may be a belt available that fits your idea.
BTW, I live near you, Hartland, WI
