Description

These instructions are compliments of Thumler’s Tumblers. Tumbling is the simplest way to polish agates and other gem stones. The rocks you use should be sorted by hardness and roughness. Your rocks may vary in size to include a few up to 1 1/2″ in diameter for the pint-size barrels and up to 2″ in diameter for 6 lb. or 12 lb. barrels. Agates and other hard stones should not be tumbled with soft material such as Opal, Tiger Eye, etc. If you are planning to tumble beach-worn rocks, don’t complicate the process by mixing them with hammer-broken rocks. When selecting rocks to tumble, remember, the finished product is determined by the quality of rocks with which you start. Your tumbler should be place on a firm, level surface with a protective tray or pan under it, and ample clearance around it. Place your tumbler where it will not be in the way; because tumbling takes several weeks of continuous operation and there is a constant sound of rolling rocks. Step 1: Fill barrel 1/2 to 5/8 full of stones. Pour in package marked coarse. Add water even with top of stones. Run tumbler with this mixture for at least 7 days, 24 hours a day, or until smooth. Wash stones and barrel well. (Kitchen colander is ideal for washing stones, but do not wash into sink drain.) Step 2: Place stones back into barrel. Pour in package marked fine. Add water even with top of stones. Run tumbler with this mixture for approximately 7 days, 24 hours a day, or until rocks are shiny when wet. Wash stones and barrel well. Step 3: Place stones back into barrel. Pour in package marked prepolish. Add water even with top of stones. Run tumbler with this mixture for approximately 3 days, 24 hours a day, or until rocks show luster when dry. Wash stones and barrel well. Step 4: Place stones back into barrel. Put in package marked polish. Add water even with top of stones. Run tumbler with this mixture for approximately 7 days, 24 hours a day, or until rocks shine when dry. Wash stones and barrel well. Step 5: Place stones back into barrel. Add enough powdered detergent to make stiff suds. Add water even with top of stones. Sawdust or other filler may be added also to cushion rocks during this clean-up stage. Run tumbler with this mixture overnight. Wash stones and barrel well. Note: Amount of grit to use: R3 Barrel or Quart Can -1 small pack for coarse and fine @ 4 oz. each, Pre-polish & Polish @ 2 oz. ea.; R6 Barrel (9 lb.) 2 small packs; R12 or B Barrel (12 lb.) 1 large pack for Coarse and Fine @ 1 lb. ea., Pre-polish & Polish 1/2 lb. ea. Spread out rocks on dry surface and inspect your finished gemstones! Note: Check tumbler during the first few hours of operation to be sure everything is working properly. Tumblers with metal cans should have edge of lid lifted slightly each day to relieve any build-up of gas pressure. NOTE: Check your tumbler lids monthly to note if any wear is occurring and have a spare on hand.
