Here are a couple shots of my tumbler affectionately known as the Cliffanator "after my dead friend that made it". It is a 55 gallon enamel lined drum with part of a subaru water pump, a square center drum with 110 us screens, not sure what the motor is from, with the pulleys I get about 35 rpm at the drum, the timer is an old darkroom timer. It's about time to clean him up and get to work, the weather is outrageous for nov not freezing yet, when it does i will post some pics.
