Replacement Drive Belts for Lortone 3A Rock Tumbler- 3 Pack

 Ean: 4903563174538   |    PartNumber: L3   |   Asin: B07YQFMR5N

A Few Hints for Longer Rock Tumbler Life Now that you are actively shopping to replace a broken, stretched or otherwise worn rock tumbler belt-your choice of our replacement belts is indeed a good One .Replacing a belt is certainly a lot cheaper than buying a new tumbler! However, please understand that early or premature breakage of your tumbler's current belt may be indicative or a "flag" telling you that other issues may be at play here (other than just a belt that broke)..If available, please refer to your tumbler's original manual. Review the important operational and maintenance information. As your tumbler (& it's belt) up to now may have been running well-there is now evidently some new checks and/or maintenance that are recommended. Examples could be: Is your tumbling load proper and not too heavy? A Heavy load will stall the shafts & pulleys eventually breaking the belt..Insure that the load does not exceed manufacturer's specifications. HINT: a 3 lb tumbler should have a load that with both it's load (rocks, water & grit) and the barrel itself measured should not exceed 3 lbs. Check and clean as necessary the outer surfaces of the barrel. Your barrel needs to be slip-free-clean & dry. Was your belt properly tensioned? The belt needs to move freely without binding or without too much excess play. Are the belt's pulleys aligned and moving freely and moving the shafts equally as well? A belt should be positioned on the pulleys with a reasonable amount of "slack" as well. Are the shafts moving smoothly, do the bearings need lubrication? Do you feel or hear any "grinding" or roughness when turning the shafts? Do the shafts' surfaces need cleaning? Remove the belt (motor) housing and (carefully)allow tumbler to run while you watch these various mechanical movements. Everything should be freely and smoothing moving-silently. With proper vigilance, maintenance and due diligence a tumbler can last & run for decades.

Kingsley Rock Tumbling Grit and Rough Rocks for Tumbling - Agates, Amethyst, Quartz and More - Rock Tumbler Refill

 Ean: 0764804510782   |    PartNumber: Various   |   Asin: B07YBK4BLH

Do you already have a rock tumbler and now need rock tumbler refill that includes tumbling grit and a wide variety of rough tumbled rocks? Are you new to the hobby of lapidary and polishing rocks or have you been doing it for decades? Either way, this kit is ideal for you. Details on what you get:

1 pound coarse 80 grit, 1 pound medium 220 grit, 1 pound fine 600 grit, 4 ounces micro alumina rock polish, 4 ounces plastic pellets and includes: 1 pound coarse 80 grit, 1 pound medium 220 grit, 1 pound fine 600 grit, 4 ounces micro alumina rock polish, 4 ounces plastic pellets, 1 pound Mexican Mix Tumbling Rough, 1 pound rough Lake Superior Agates, 1 pound rough Amethyst, and 1 pound rough Quartz Crystal Points. Wow!

1 pound rough Lake Superior Agates: These multi-color agate tumbling rocks come from the Lake Superior region. You get approx. 50 pieces. The rainbow of colors are caused by impurities and occur as alternating bands within the agate, creating interesting and pretty patterns. Hard, multi-banded, takes an excellent polish. Moh's hardness of 7.

1 pound Amethyst: This tumbling rough is a purple variety of crystalline quartz with a Moh's hardness of 7. Amethyst is good for beads or tumbling. Approx 15-20 small pieces .5" to .75" size. Did you know? Amethyst's principal virtue during the Middles Ages was to protect the wearer against drunkenness from either liquor or love, and to induce clear thinking.

1 pound Mexican Mix Tumbling Rough: A good assortment; 10 to 12 pieces. Great for beginners or for fill. You get a wide variety of pretty colors when polished.

1 pound rough Quartz Crystal Points: Approximately 130 small pieces of quartz crystal clear/translucent points. Some pieces may have chips or imperfections.

Features

  • Rock Tumbling Grit Kit includes: 1 pound coarse 80 grit, 1 pound medium 220 grit, 1 pound fine 600 grit, 4 ounces micro alumina rock polish, and 4 ounces plastic pellets.
  • Rough Rocks for Tumbling includes: 1 pound rough Lake Superior Agates, 1 pound rough Amethyst, 1 pound rough Quartz Crystal Points, and 1 pound Mexican tumbling rough.
  • Rock Tumbling Grit Kit contains enough grit to finish 8-10 pounds of beautiful gems.
  • This kit allows you to get excellent rock polishing results, and also makes a great gift for someone who already has a Lortone or other brand of tumbler and now needs rock tumbler refill.
  • It takes years and years for nature and its elements- dirt, rock, water, and sand- to smooth a rock's surface. But with your own rock tumbler and kit of rock tumbler supplies, you can get those same results in considerably less time with the hobby of lapidary!
