Rock Tumbler Ideas Answered
Hello, first off, thanks for taking the time to read my post.
Second, I'm brainstorming ideas to make a dirt cheap rock tumbler, for polishing collected stones and maybe even making jewelry out of them. There are a few sites out there with instructions on making rock tumblers and other equipment. Some being:
The design seems to basically be a rotating horizontal plastic or rubber cylinder, set on two evenly spinning axises. I was thinking of using 4" PVC pipe as the tumbling barrel, and maybe 1" PVC for the axises. One of my first questions is, will a large desktop fan be (roughly) powerful enough to turn the 4" barrel at 50-100 rpm? Keep in mind these are plans for a dirt cheap rock tumbler, so I really don't want to spend much on these parts. Any other suggestions for motors?
And, does anyone have any plans that they have made, or even constructed tumblers?
Any tips, additions, etc. to my plans?
Thanks for reading my post :)
