Thumler’s Tumbler Ultra-Vibe 18 (industrial model)

For rock tumbling or jewelry finishing. Other jewelry fabrication tools available. See my other listings. Excellent condition - used only two or three times. New would cost $519, asking $250 Description copied from RockTumbler.com: This is the industrial version of Thumler's UV-18 vibratory tumbler that is designed for tumble polishing rocks or finishing metal parts. It has a heavier duty motor, springs and bowl than the light duty version designed for cleaning brass and jewelry. That is why it costs significantly more than the light-duty version supplied with a yellow striped bowl. A vibratory tumbler is a much faster and more economical way to polish stones when compared to a rotary tumbler. Thumler's UV-18 tumbler can process more material than a Model B rotary tumbler in about half the time while using significantly less grit. A large grit savings comes from not using coarse grit. The first step in vibratory tumbling is medium grit. You then go to fine grit and finish up in polish. This tumbler will also work great for polishing brass cartridge cases. It can clean and polish between 200 and 700 cases, depending on their caliber. Polishing brass requires the use of corncob or walnut shell media. Thumler's 18lb vibratory bowl measurements This tumbler's bowl can handle some good size pieces of rough. To fit into the bowl one dimension of your rough must be smaller than 2 7/8 inches. That is the size of the opening between the raised center and the bowl's top opening. The other dimension of the rough should not exceed about 3 1/2 inches. When processing pieces of this size we suggest only two or three per batch. The rest of the bowl's capacity should be filled with smaller material. This smaller material can be ceramic media or rough with a range of sizes between 1/4 inch up to about 1 1/2 inches. If you tumble only large pieces they will bruise one another and possibly damage the machine.

Rough Size: One dimension of the rough must be less than 2 7/8 inches to fit into the bowl. The other dimension should not be more than 3 1/2 inches.
