Wind Powered Rock Tumbler

in #rocks • 7 years ago

I spent about $40 making this wind powered rock tumbler. I should have videoed the progress of the rocks but maybe next time.

Used some PVC pipe and threaded plugs for the ends.

Here's the first time in the wind to see if it will tumble.

Here it is finished and tumbling.

It took several weeks to polish the rocks but no electricity or annoying noises in the garage or basement.
