Rock Tumbler Buying Guide - What You Need to Know!

Rock tumblers are a great way to polish rocks and gemstones. They come in various sizes and shapes and can be used for a variety of purposes.

Rock tumbler comes in various sizes and shapes. They are usually made from plastic, acrylic or stainless steel. This machine is mainly used for polishing stones like quartz, agate, amethyst, jasper, opal etc.

The benefits of using rock tumbler:

  • It helps polish stones
  • It is cheaper than other methods like using sandpaper or diamond dust
  • It can be used to create jewelry pieces

4 Things To Consider When Buying a Rock tumbler

Most people buy tumblers without any additional reading online, but those who fancy trying before they buy may be interested in reading some basic instructions first.

Selection of Material

Careful selection of Rocks will provide me with the best finished results -Cracked or sharp rocks may need to be removed before you start work (wear appropriate safety equipment before attempting this) Rocks of the same hardness level and mixed size would be best.

Setting Up

Fill the barrel about 2/3 of the way with rocks, and add just enough water to reach the top of the rocks. The barrel must never be more than 3/4 full or less than half full. If you find that the load is too slim and lose some of it in phases 1 and 2, you can add pellets to again reach the required amount. Ensure the jar and lid are completely clean before closing the lid.

Fill the barrel with water and put it on the Tumbler. It's a good idea to watch for about 48 hours, check there are no leaks, and make sure the barrel is rotating well. Leave it charging for around 6-7 days (you can check every 24 hours if you like).

Grit Recommendations

The first stage is usually a Coarse Grind, which is typically achieved with 80 Grit Silicon Carbide or equivalent. If you want a very smooth tumbler or if you're using a vibratory tumbler, skip the first stage and go directly to the Medium Grind. The shape of these grinder teeth is usually fine, although sometimes they can be coarse. The 3-stage process begins with pre-polish and is followed by a higher grit. The pre-polish can use 600 Silicon Carbide or another type of pre- polish such as 1500 Aluminium Oxide.

The quantity of grit to use is determined by your tumbler instructions, but 1-5 tbsp/kg (or 3-5 tbsp/kg for the first & second stages and less for the third & final stages) would be a rough guideline. Generally you will use less than a kilo of rock in a 3 pound barrel, so to use the lower end of those usage rates is fine.

Running out of time to prepare? Check out these essential tips that will help you get back on track. Add the appropriate level of liquid to your barrel, usually around two thirds or three quarters full. This is the best condition for tumbling. Investigate each stage of the process and only move on to the next one once you are satisfied that it is complete.

DO NOT tip jar contents down the sink. This can cause a blockage, leading to expensive plumbing fees - it's better to clean up outside which is less likely to end up in someone else's garden. The solid residues from this can usually be thrown away with normal household waste, and the plastic itself will not degrade under landfill conditions. Consider buying a spare barrel to keep grinding polishing different stages separately. Between stages, you will still have to wash the wheel carefully but this greatly reduces the chance of coarse grit getting into the next stage.

Polishing

Marking and polishing are usually the most challenging stages of any works and you may need to try out some trial-and-error before getting the desired result. Our 3-in-1 Cerium Oxide Starter Kit is great for many types of rocks, but not all. It is priced cheaply and comes with a two year warranty.

Tin Oxide or Aluminium Oxide 14k are both good general purpose polishes for most types of rocks including the harder ones up to 8 hardness. If Cerium Oxide is not working well for you, then one of these two might be the better option. You might need to try a few different text editors until you find the right one that suits your project.

Cerium oxide is good for softer materials such as opal and glass as well as quartz rocks - in the 6 to 7 hardness range. For more scratch-resistant gems such as garnet, topaz, beryl or spinel, we would recommend Tin or Aluminium Oxide.

Not all rocks will polish well - a good rule of thumb is if the rock is glossy when wet but dulls as it dries out, it is a good candidate for tumble polishing - if the rock remains dull when wet, or has a rough surface or is porous, it is unlikely to polish.


FAQS

Does a rock tumbler really work?

Most rocks will not do well in a rock tumbler, but a few types of rock will tumble well for beginners if you select the right ones. These easy to tumble rocks include agates, jaspers, chalcedonies and petrified wood.

How long does it take to polish rocks in a rock tumbler?

And that's the thing with a rock tumbler - it can take as short as one week to two months to refine rough, unpolished stones into highly lustrous, smooth stones. The amount of time that it takes to tumble your pile of rocks will depend on what type of tumbler you use, the type & size of rocks that you tumble and how picky about the shape of your stones you are.

How long does a rock tumbler last?

To create the perfect polish, most vibratory tumblers are run for 12 to 24 hours with a medium grit. Once the grit and mud has been washed off the rocks they are left sparkling clean.

Do rock tumblers need water?

How much water should you add? Just fill your kettle up until the water level is touching the bottom stone layer. Ensure that the barrel is charged and within the weight allowance before starting. It's also true that the surface where we seal and the lid are easy to clean.

What should I look for in a rock tumbler?

When looking for a rock to tumble with, it is important to make sure it is hard. It should be nonporous and have a smooth surface. It should also not be too gritty. Some of the most popular types of rock with these properties are agate and jasper – both are forms of quartz.

What size rock tumbler is best?

To make a 1.5-ton barrel, you would need 3 pounds of rocks and 2 pounds of grit. If you're just looking to tumble casually, try a 3-4lb tumbler.
