I thought I should share a recent batch that processed through our smallest tumbler. This is from both barrels on a Thumler A-R2 - about 6 pounds of rock. One barrel was all Lake Superior agates. The other barrel was an assortment of rocks that I recycled from other runs. That A-R2 is really the little tumbler that could.
