Review: high capacity great price - i bought this tumbler due to its high capacity and the excellent price. its a sturdy machine and at 25lb capacity the opening is big enough for larger items. as of yet no signs of issues. great value
Review: Better than most - This tumbler is better than most for durability and versatility. Make sure to purchase Lithium Grease you will need it to operate. The price is expensive but it’s a well built tumbler base. And it’s versatile in that this one tumbler can fit a variety of barrel sizes. I purchased the 10lb barrel and have been running 2 3lb barrels. To run smaller barrels I did have to make a modification to the nylon bumper, by adding a longer bolt with a nylon washer to extend the bumper out farther. The MJR barrels have a wide ridge that sits in the rollers. Smaller barrels don’t have such a wide ridge which means they could slip off the rubber roller track. Simple fix to make this adaptable to more barrel combinations. Primary issue noted is belt breakage. The manufacturer sells replacements for $8-15 (depending on tumbler base size) for only one belt. These are just simple O Rings. The size for the 10 lb. tumbler is 4 1/4” x 3/16 “. I found Nitrile O-Rings for $12. Don’t get durometer harder than 70 or they’re too brittle and snap.
