The Lortone 33B is a double-barrel rotary tumbler built for jewelry and lapidary work. It runs two rubber barrels on a steel frame with a precision-balanced motor, so it can burnish metal clay and metal pieces or polish stones in one session. Lortone tumblers are rated for the weight of stainless steel shot, which is why jewelers use them for tumble finishing. Owners value the quiet rubber barrels and the long service life; the trade-off is that it is a slow, heavy machine that needs shot, water and compound to do its job.

Jewelers and lapidary hobbyists rate the 33B as a dependable workhorse. They praise the quiet rubber barrels and the twin-barrel setup, and say it keeps running for years. Complaints center on its weight and on the upkeep of belts and barrels over time.
The Lortone 33B is a double-barrel rotary tumbler that runs on 115V US power. It is built to handle the weight of stainless steel shot and is widely used in the jewelry industry. Tumble finishing puts a shine on metal clay jewelry, and pieces are work hardened in the tumbler, which benefits fired metal clay.
It has a steel frame and a precision-balanced motor for long-lasting use, even under continuous operation. The rubber barrels reduce noise compared to plastic models. It can also be used to polish rocks, gemstones, glass and metal jewelry. It is designed and made in the USA.
To use it, put 1 lb to 2 lbs of stainless steel shot in each barrel. Add fired items, brass brushed first. Pour in enough distilled water to cover the shot, then add 1 drop of mild dish soap as a burnishing compound. Soap must have no additives such as anti-bacterial agents or lotions. Put the lid on, set the barrels on the rollers, and tumble for one to two hours.
