The tumbler works best with a small amount of tumbling fluid in the container - it doesn't need a lot, too much will stop it from working effectively - but it's important because it prevents hazardous dust from becoming airborne.

Wear nitrile gloves when you are working in and around the tumbler. The slurry that is produced is messy and may stain your skin for a while because it contains very fine abrasive media. You will need to thoroughly clean your parts after tumbling, especially if they are going on for further processing like anodising or plating. | Wear nitrile gloves when you are working in and around the tumbler.

You may find your parts come out with softer edges than when they went in - this is an expected part of the tumbling process. You can try to experiment with different media types and different durations. | You may find your parts come out with softer edges than when they went in - this is an expected part of the tumbling process.

We store tumbler media in a number of plastic bins under the tumbler bench. If you change the tumbler media the tumbler tub must be cleaned thoroughly before introducing the new media. | We store tumbler media in a number of plastic bins under the tumbler bench.
