Okay, I'm "considering" building a combo machine forball millingand star rolling. The thing I'm confused about is theRPMof the drums. I always thought aball millshould be fairly slow because rock tumblers that I've seen are fairly slow - maybe 60 revsper minute. I guess I'm wrong. I've seen recommendations of much higher speeds. Of
