Home-Made, High-Capacity Rock Tumbler: Easy Build

In this video I show how I construct a super simple, home-made, high-capacity rock tumbler that can handle up to four 6 pound tumbling barrels. It was built using inexpensive and readily available materials and replacement Lortone tumbling barrels, which can be bought for a fraction of the price of whole tumblers. Please visit my web site at http://mdpub.com/ for more information.

Items used in this build:
2-4 Lortone 6 lb tumbler drums
~1/5 HP ac electric motor salvaged from another project w/ 2.5 in pulley
