Frequently Asked Questions (FAQs)
1. What media do you use to tumble rocks?
Ceramic tumbling media is commonly used in rock tumbling. It is added to the barrel to provide several benefits, including filling up empty space, cushioning the stones, improving tumbling action, and carrying grit to hard-to-reach places. Using ceramic tumbling media can help achieve better results in rock tumbling.
2. How many times can you reuse tumbler media?
The lifespan of tumbler media depends on the type of media used. Organic tumbling media like corn cob or walnut shell can usually be reused for about 10-20 runs before needing replacement. However, stainless steel media can last for a long time without degrading. It is important to monitor the condition of the media and replace it when necessary for optimal results.
3. How often do you change tumbler media?
The frequency of changing tumbler media depends on the specific media used and the condition of the media. As a general guideline, corn cob media typically lasts for about 10-15 runs before needing replacement. It is recommended to replace the media when the cleaning and polishing process takes about twice as long as the initial run with that media.
4. What liquid do you use to tumble rocks?
For rock tumbling, a common practice is to fill the barrel with tumbling rough, add two level tablespoons of coarse grit (such as 60/90 grit silicon carbide) for each pound of rock, and then add water until the water line is just below the top of the rocks. This mixture of water and grit helps in the tumbling process and achieves desired results.
5. What is a substitute for rock tumbler grit?
If rock tumbler grit is not available, silica sand can be used as a substitute. However, it is important to note that using silica sand as a substitute will lengthen the tumbling process compared to using commercial rock tumbling grit. Silica sand can typically be found at local sandblasting companies.
6. What grit sandpaper for stainless steel tumblers?
To buff stainless steel tumblers, it is recommended to start with sandpaper between 150 and 240 grit. Some professionals suggest progressing to higher grits like 400, 600, and even 1200 for a smoother finish. For a mirror finish, a 2000 grit sandpaper may be used. The specific grits used may vary depending on personal preference and desired results.
