Big Tumbler Cleans Parts Safely
Forget about sand blasting or wire brush cleaning delicate or hard to replace parts. The Eastwood jumbo parts tumbler can clean parts up to 10 in. long, removing build-up and bringing them to a mirror shine. The tumbler uses vibration, not rotary action, to clean parts.
John Sloane, Eastwood Company, says, "The most common use of our tumbler is for small brackets and hardware from collector cars. The tumbler lets you load it up and forget it, with only periodic checks to see if the parts have reached the desired stage."
The key to the tumbler's effectiveness is the media or material used in the tumbler and the adjustable vibration, from mild for gentle cleaning to aggressive for quicker cleaning. Eastwood sells a wide variety of media from plastic pyramids to ceramic and hardwood cubes. The plastic and ceramic media are impregnated with an abrasive. One media, Dry Shine, is treated corncob pieces. It is used to produce the mirror shine on metal. Additives such as Fast Etch, a dilute phosphoric acid solution, leave a protective coating on the cleaned metal.
"Fast Etch will inhibit rust for a while, but it is good to get freshly cleaned steel or iron recoated," says Sloane. "However, tumbling won't leave it as oxygen hungry as sandblasting."
Some media will wear away faster than others, and most media will need to be cleaned periodically. Hardwood cubes and corncobs may need to be refreshed occasionally, as well. However Sloane reports using a tumbler for 7 days straight with no discernible change in the media size.
"You can overdo it, but tumbling is a more controllable process, and you can stop before you actually damage tolerances," he says.
Eastwood's jumbo tumbler features a high-density, polypropylene, 22-in. diameter bowl. It can hold up to 50 lbs. of media and parts and sells for $549.99.
