the heart of the machine is a drill press motor I got for free
the motor comes in contact with the front wheel. I put grip tape on the shaft I think you can see it. The motor is adjustable and the small diameter of the motor shaft contacting the larger wheel slows the tumbler down to a good speed.
More grip tape on the rim of the bucket where it comes in contact with the wheel
