I have my eye on a Gy-Roc Vibraphone and am wondering if this would be a good machine for tumbling rocks. I have a couple belt tumblers and tend to break belt more then I would like with them. I have read that the vibration type machines use less grit and get the job done faster then conventional tumblers . Would the Gy-Roc be less noisy then say a Thumlers tumbler would be? Thank you for any insight into the comparisons of the 2 types of units.

Vibrahone, not phone but good tumblers. I had a C (40 lb. unit) that ran much quieter than my little B model (2.5 lb.). The B sounds like an electric shaver gone mad. They are very fast and frugal with grit (B uses 1 tsp. and A unit (1o lb.) uses 1 tbs. I think Johnson Brothers just bought the rights to build the Gy-Roc but I heard it from the head of Covington who heard it from the original owner of Johnson Bros. I have a few new C models left in stock if you want to do lots of rocks fast. They use a "heaping tablespoon and a half" but I only used mine for burnishing aluminum castings.

Thanks you all for your reply's. Yep, Kevin its the one on ebay. Sorry about bidding against you. Didn't know I had any responses yet on my thread. Didn't show any messages. Just not thrilled with my tumblers so thought I would try vibration. I just started rock collecting.
