How to Choose a Tumbler
1) Buy quality
Good tumbling results starts with a good machine. Take your time and find a dealer that will help you decide on the correct model for what you plan to tumble.
2) Find the right size tumbler
Even though all tumblers do the same basic job, the size can still affect the results. Not only do larger tumblers require more rock to operate efficiently, they also consume more grit and polish. Buy a small tumbler if you are just getting started or plan to tumble smaller loads. Buy a mid-size tumbler if you need to tumble larger stones (2" to 2.5") or have larger amounts. For production runs, choose a commercial unit.
3) Build a relationship with a dealer
Find a reputable dealer that spends time with you, listens to your needs and helps you through trouble spots.
