Check out what my dad made for my shop! Out of scrap metal, some barrels, and a few other parts he made these awesome tumblers. A larger one for bigger hides filled with sawdust, and a smaller one for birds with corn cob grit. The motor is interchangeable and goes from one tumbler to the other in just a couple minutes. Here are a few pics of them both. Just thought I'd share how handy my dad is! This is one of the motor. Then the smaller bird tumbler has the same receiver to put the motor on! I Love it!
