If anyone wants to build a similar tumbler most of t parts can be found at home Depot. I used a 1/2" floor flange and a 3" nipple to connect the bucket to the motor shaft with a piece of heavy duty heater hose and two hose clamps. A 5" 1/8 round aluminum disc with four bolt holes drilled in it to match the hole pattern on the floor flange., 1-1/2" bolts, washers, nuts to attach to the bottom of the bucket after drilling matching holes in bottom of bucket. You can use wood furring attached to the inside of the bucket with screws and washers for paddles or apply the paddles to another bucket that you can slip inside the drive buck, using the drive bucket as a carrier for the paddled bucket. Easier to empty the tumbler regardless of what you're tumbling.
