Delivering outstanding performance and with a overall capacity of 12 lbs., this single-barrel tumbler can accommodate up to 6 lbs. of steel shot for effective, efficient results. Keep in mind that the workpieces added will increase the weight, up to a max. of 12 lbs. Designed for continuous shop operation, the Lortone QT12 tumbler features a 10-sided barrel, a leak-proof closure, an overload-protected motor and a rugged steel frame.
please note: If you will be using Super Sunsheen or other caustic compounds in your tumbler, dilute the compound to 50% of the recommended strength to prevent breakdown of the rubber interior of the barrel. Do not use with solvents or harsh detergents.
Getting the Best Results from Your Rubber Barrels
As much as the right media and the right solutions, your tumbling barrel is crucial to achieving consistent, quality jewelry finishing results. If you use a rubber or neoprene barrel, you should know that some solutions can be too caustic for the barrel and can cause the rubber inside the barrel to break down. This possibility increases with lower-quality rubber barrels. You will know if this type of breakdown is occurring when you open your barrel and see your pieces covered in a black sludge or a yellowish, blackish, or bronze-color film. This film, or sludge, is the result of carbon and oil being leached from the interior surface of the barrel by strong or caustic solutions. Here are ways to clean a contaminated barrel and to prevent this breakdown from taking place.
SOLUTIONS TO AVOID: • Ammonia solutions • Bleach solutions • High-alkaline content solutions (ingredients such as borax) • Solvent-based solutions (including acetone and citrus cleaners) • Solutions with high concentrations of mild chemicals (such as soap)
HOW TO CLEAN A CONTAMINATED BARREL
Clean out your barrel with an acidic solution such as Coca-Cola (yep, Coke; allow the cola to go flat before using it), vinegar and water, Lime-A-Way® or CLR®).
Run the solution and your shot in 20-minute cycles, rinsing thoroughly between each cycle until the shot is shiny and clean.
Workpieces that are contaminated with sludge can be run in the barrel with the cleaning solution, or they can be cleaned by hand using a toothbrush dipped into the solution.
AVOIDING BREAKDOWN OF RUBBER BARRELS
If you are just starting to use a new rubber barrel and new shot, run the shot in vinegar and water (50/50 solution) for at least three 20-minute cycles, followed by a 20-minute rinse cycle with water and about 2 tablespoons of baking soda.
When using lower-end, economy barrels, run just plain water with a single drop of castile, pH-neutral, or Ivory® brand liquid soap.
If you use Super Sunsheen® solutions, dilute the Sunsheen to half of the recommended strength.
Run short cycles and check your water often. If you find that your solution is becoming yellow (the first sign of breakdown), run a cleaning cycle, then change to a milder solution or further dilute the solution you were using.
