Rock Tumbler Grit: How to Use, Reuse and Substitute

Rock tumbling is an intriguing hobby that involves taking rough rocks and tumbling them to a polished and shiny finish. Whether you are new to rock tumbling or an experienced hobbyist, the quality of your tumbling experience can depend on the quality of your grit.

In this article, we will discuss how to use, reuse and substitute rock tumbler grit to help you achieve the best results. Reusing Grit: Risks and Safety Precautions

While reusing rock tumbler grit may seem like a practical idea to save costs, it can pose several risks.

Firstly, reusing grit can damage your rocks, causing visible scratches and scuffs that would require additional polishing to remedy. Moreover, reused grit may contain dirt and debris that can increase the wear and tear on your machine, eventually leading to costly repairs.

Another concern with reusing grit is the electricity cost involved in running your tumbler for longer periods than necessary. You may think you’re saving money by reusing grit, but it could end up costing you more in the long run due to higher electricity bills.

Instead of reusing grit, consider using plastic filler pellets used for cushioning and protection when shipping delicate items. These filler pellets can be easily purchased online and provide a practical solution for filling the empty space in your tumbler barrel, preventing your rocks from clumping and reducing wear and tear on your machine.

Using a filler is not a risk-free option, however. As flammable materials, you should always use them cautiously, ensuring that they do not clump or melt during the tumbling process.

Substituting Grit: Silicon Carbide is Key

If you do not have access to the right grit, rocks can take much longer to tumble, and the final finish may not be as polished and shiny. When it comes to grit, the rule of thumb is always to use Silicon Carbide grit as it has the desired shape and type, and required hardness.

Silicon Carbide grit comes in different grit sizes and types, such as black or green. Black Silicon Carbide grit has a higher hardness range compared to a green one and is suitable for grinding harder stones.

In contrast, green Silicon Carbide grit is more from the grinding process and is suitable for softer stones. When buying Silicon Carbide grit, consider buying in bulk to save money.

It’s also worth shopping around to find suppliers offering good quality grit but at reasonable prices. However, be cautious of cheaper suppliers who may provide poorer-quality grit that may not produce desirable results.

To save costs when tumbling rocks, consider using a less expensive grit for the first step of the tumbling process and switch to better-quality grit for the polish stages. This approach helps to achieve a more polished final result.

In conclusion, when it comes to rock tumbling, using suitable grit is important for achieving desirable results. Reusing grit may seem like a practical solution to save costs, but it comes with its risks that can damage both your rocks and machine.

Instead, substituting rock tumbler grit using plastic filler pellets or buying Silicon Carbide grit in bulk and switching to less expensive grit for intermediate stages can help achieve a polished and attractive final finish on your rocks. Grit tumbling is an essential process in achieving beautiful and polished rocks.

Once the rocks are tumbled and the grit has been used, the next step is to dispose of it properly. It’s important to note that improper grit disposal can cause plumbing problems and damage the environment.

In this article, we will discuss proper grit disposal and the differences between rotary and vibratory tumblers.

Dangers of Rinsing Grit Down the Drain

One of the most significant problems with rinsing grit down the drain is that it tends to create a cement-like substance over time. This can cause blockages in your pipes, resulting in expensive plumbing damage.

Furthermore, the cement-like substance can also cause problems in the municipal sewage treatment plant and other water treatment facilities. Popular Ways to Dispose of Used Water, Slurry, and Grit Particles

An appropriate way to dispose of grit is to throw it out into your driveway, garden, or woods.

When disposing of the waste, it is imperative to use a plastic bag and throw the waste in the trash. Additionally, You can collect and dispose of the slurry created during tumbler use by pouring it into a plastic container and allowing it to dry out before throwing it into the garbage.

However, Caution should be exercised when disposing of the slurry in outdoor areas since it contains grit, which is a man-made substance, and animal or ground contamination can occur. A solution to this problem is to mix the used grit with compost and use it as an organic fertilizer in your garden.

This method is environment-friendly and a great way to reuse your grit.

Differences Between Rotary and Vibratory Tumblers

Rotary and vibratory tumblers are two different types of rock tumblers that can be used to polish rocks. Rotary Tumbler: A rotary tumbler is considered the industry standard for tumbling rocks.

It uses a barrel that rotates during the tumbling process, which ensures that the rocks are consistently exposed to the grit. The amount of grit used is determined by the size of the barrel, and the tumbling process takes a longer time.

Rotary tumblers are ideal for tumbling larger rocks. Vibratory Tumbler: A vibratory tumbler uses a vibrating motion that keeps the rocks and grit in constant movement.

It uses a lot less grit than a rotary tumbler due to the unique way the tumbling process works. However, the tumbling process takes less time than the rotary tumbler and is ideal for small rocks.

Vibratory tumblers generate a lot of dust compared to rotary tumblers.

Not Recommended to Reuse Grit in Either Tumbler

As mentioned earlier, it is not recommended to reuse grit in either tumbler. While there are various ways to clean it, the risks simply outweigh the benefits.

Tumbling smooth rocks for the second time using the same grit reduces its efficiency. As a result, it’s best to switch out the used grit and replace it with fresh grit for the best results.

In conclusion, when you’re done with the tumbler, it’s important to dispose of the used grit properly. Throwing it into your garden or driveway can lead to adverse environmental impacts.

If you’re not sure how to dispose of it, check with your local authorities to find out what options are available. Rotary and vibratory tumblers have their strengths and weaknesses, and the decision on which one to use will depend on your unique preferences.

In either case, it is best not to reuse the grit, and the used grit should be disposed of properly. Using a tumbler for rock polishing can be a fun and rewarding hobby, but it requires precision and care in using tumbler grit.

To achieve desirable results, it is essential to use the right amount and type of grit and adopt best practices when tumbling rocks. Here are some tips to help you get the most out of your tumbler grit and overall rock tumbling experience.

Using Separate Barrels for Polishing Stages

It’s essential to use a separate barrel for each stage of the rock tumbling process. Initially, coarse grit is used, followed by fine grit and then finally polish, each in a separate barrel.

Using separate barrels minimizes contamination, which is crucial for a good polish. Combining the grit can result in the coarse grit scratching the surface of the rock, reducing the overall quality of your polish.

Tumbling Rocks Together That Are Similar in Hardness or Size

It’s essential to tumble rocks together that have similar hardness or size. This allows the rocks to tumble evenly without one rock chipping or breaking and damaging other rocks or the barrel.

To ensure even tumbling, you should opt for a variety of sizes to prevent clumping and overloading.

Using Water Pick to Clean Rocks Between Steps

A water pick is an excellent tool for cleaning rocks between stages. It is great for removing grit and slurry from the crevices of the rocks.

You can use it to clean your rocks before adding a new stage of grit. A water pick is also useful for washing the tumbling barrel.

It helps remove any residue from previous stages and ensures that the barrel is clean for the next stage.

Using Two Tumblers to Combine the Benefits of Both Types

Using two tumblers can be a great way to combine the benefits of both rotary and vibratory tumblers. The ideal combination is to start with a rotary tumbler for the first stage of coarse grit and finish off with a vibratory tumbler for the final stage of polishing grit.

The rotary tumbler prepares the rocks for the finer polishing, while the vibratory tumbler provides a smoother finish. Using two tumblers is ideal when dealing with large batches of rocks.

Ability to Re-Tumble Rocks for an Even Smoother Look

Re-tumbling rocks can assist in achieving an even smoother look. Sometimes, rocks may not come out as smooth as you desire, particularly if they have intricate shapes.

This problem is common when using rotary tumblers. To remedy this, you should re-tumble the rocks in the same stage of grit as before and check the progress regularly.

Re-tumbling ensures a smoother, more polished finish for your rocks. In summary, using tumbler grit can be an excellent way to polish your rocks with a professional finish.

Proper usage requires care and precision. Adopting best practices like using separate barrels for each stage of the tumbling process, tumbling rocks with similar hardness or size, and cleaning rocks between stages ensures safer and desirable results.

Using two tumblers, specifically rotary and vibratory tumblers, combined with the ability to re-tumble rocks can result in even smoother, professional-looking finishes. In conclusion, proper usage of tumbler grit ensures a polished and professional finish for your rocks.

From using separate barrels for each stage of the tumbling process to tumbling rocks with similar hardness or size, and cleaning rocks between stages, these are some essential tips to get the most out of your rock tumbling experience.
