The Vibrating Tumblers or the Rotary Tumbler which one works and which one doesn't. Rock tumbling for beginners you have so many choices but which one to buy. What equipment do you need to polish your rocks. The vibrating tumbler show is not made for wet rock polishing. It is used for polishing tools using a dry media such as walnut shells.
