I get a lot of feedback about people making their own rock tumblers. These videos show how to make them yourself and what they look like- DIY rock tumblers. If you want to submit your own step by step rock tumbler instructions or video just send me an email.
This is a very inexpensive one that works!
Thanks and enjoy, Gary-
- Salvaged 1/5hp AC motor from a whole-house exhaust fan
- 4 pillow block bearings ($9.95 each on eBay)
- Fan belt ($9 from Farm & Fleet)
- 3/4″ FIP black iron pipe ($6.50 for each 2′ piece at Menards)
I had to grind 1/16 of an inch off the circumference of each end of the iron pipes to get them to fit inside the 1″ bearings. I went through two bench grinder wheels doing it. Wooden 1″ dowels would be a simpler, easier solution.
Just make sure there’s adequate airflow to keep your motor cool.
