PARTS TUMBLER BASIC KIT*

THE ASSEMBLED TUMBLER PICTURED IS FOR INFORMATIONAL PURPOSES ONLY.

*This is a kit and requires the purchase of additional parts (i.e. hardware, chain, bucket, wheels, drill motor, etc).

The kit includes ONLY the custom metal parts shown in the drawing (photo #2). We will weld any parts that need welding plus drill and tap any holes that need threads.

*Requires additional parts/hardware to complete (all common). After purchase, we will provide a detailed parts list, instructions, photos, and videos to help you build your parts tumbler. A list of additional parts and hardware required is also included in the listing (see photos).

BACKGROUND: We plasma cut a lot of parts like steel tabs and large washers. The cheap vibrator type tumblers and roller driven tumblers were just not effective and could NOT handle the heavy steel parts so..... we designed our own heavy duty chain driven tumbler. This tumbler design was so effective that we decided to share the plans. Capacity is not officially rated, however, the tumbler is specifically designed for heavy loads. It can easily accommodate 50 large 3 inch x 3/16 steel parts (plus the de-burring media).

OVER HEATING: Running your tumbler too slow may cause overheating. Drill motors have an internal fan that needs to turn at least fast enough to exhaust the hot air from inside the drill. Check your drill for overheating and adjust the load or speed if required. Point an external fan at the drill if needed on hot days to keep the motor cool and to extend the life of the drill motor. Keep the drill clean and blow it out routinely to remove any dust build-up.

CHAIN ALIGNMENT: Be certain that the chain engages the gears smoothly. Adjust (bend if needed) the drill mounting brackets as required to insure that the gears and chain are all properly aligned. A mis-aligned chain will tend to 'click' or even jump off the gears.

TUMBLING HEAVY LOADS: We have found that when the tumbler is first loaded with a extremely heavy load, the drill may turn slowly or unpredictably until the bucket has turned several revolutions and the load has been evenly distributed. THIS IS NORMAL. Once the load has been distributed evenly, the speed may increase. Adjust speed downward as needed. 60 RPM seems to work well. If you run the tumbler too fast, you'll hear the parts bumping around (like tennis shoes in the clothes dryer). When you find the correct speed you'll hear more of a constant "whooshing" sound and see a balanced, perpetual 'wave' inside the tumbler.

WARNING: Never leave machinery operating unattended. Keep clothing, long hair, fingers, and jewelry away from moving parts. Keep pets and children away from equipment when operating. Unplug from the power source when not in use.
