This configuration turns the stones at 56 RPM on low speed and 83 RPM on high speed. First consideration: Belt or Chain. Though chains and sprockets are heavier, they allowed me to bypass the need for tensioning mechanisms and adjustments. Just put the sprockets where they need to be and cut the chain to length, leaving a tiny bit of slack.
