My Buying Guide on ‘Rock Tumbler National Geographic’

As a rock collector and enthusiast, I have always been fascinated by the smooth and shiny appearance of tumbled rocks. That’s why I decided to invest in a rock tumbler to turn my rough stones into beautiful polished gems. After researching various brands and models, I came across the Rock Tumbler National Geographic and it has exceeded all my expectations. In this buying guide, I will share my first-hand experience with this amazing product and help you make an informed decision.

What is a Rock Tumbler National Geographic?

A rock tumbler is a machine that uses rotational tumbling to smooth and polish rough rocks, minerals, and gemstones. The National Geographic Rock Tumbler is a high-quality tumbler designed for beginners as well as experienced rock enthusiasts. It comes with everything you need to start tumbling right away.

Features to Consider

When looking for a rock tumbler, there are certain features that you should consider to ensure you get the best quality product. Here are some features that make the Rock Tumbler National Geographic stand out:

  • Durable Motor:The motor is the heart of any rock tumbler, and the one in National Geographic is built to last. It can handle large loads and continuous operation without overheating or breaking down.
  • Multiple Barrels:This model comes with two barrels which allow you to tumble two batches of rocks simultaneously. This saves time and increases efficiency.
  • Dual Voltage:The Rock Tumbler National Geographic can be used with both 120V and 240V power outlets, making it suitable for use in different countries.
  • Noise Reduction:The rubber barrel lining reduces noise while tumbling, making it ideal for use in homes or offices without causing any disturbance.

Tumbling Process

The tumbling process can take anywhere from 3-4 weeks depending on the type of rocks being tumbled. However, here are some tips that can help speed up the process:

  • Rough Grinding Stage:This stage takes around one week and involves using coarse grit to smooth out any rough edges on your rocks. I recommend running this stage for at least seven days for best results.
  • Medium Grinding Stage:The medium grinding stage takes about one week as well, but this time using medium grit instead of coarse grit for finer polishing.
  • Fine Grinding Stage:In this stage, use fine grit for another week to achieve a smoother finish on your rocks.
  • Precious Polishing Stage:This final stage uses polishing powder or polish compound with water to bring out the shine in your gems. This stage typically takes around one week as well but can be extended for better results.

Additional Accessories

The Rock Tumbler National Geographic comes with everything you need to get started; however, there are some additional accessories that can enhance your tumbling experience such as different grit sizes for more variety in finishes, extra barrels for larger batches of rocks, and different types of polishing compounds or powders. These accessories are easily available online or at most hobby stores.

Cleaning and Maintenance

Cleaning your tumbler after every use is crucial for maintaining its performance and longevity. Make sure to clean all parts thoroughly with water and dry them before storing them away until next use. Also, regularly lubricate the motor bearings with lightweight oil or grease recommended by the manufacturer.

Final Thoughts

The Rock Tumbler National Geographic has been an excellent addition to my collection tools; it’s easy-to-use, durable, efficient, quiet operation makes it perfect for both beginners and advanced users alike. With proper care and maintenance, this tumbler will last you many years while producing stunning polished gems every time!
