Not Telling
If you're looking for a cheap motor, I would head to eBay. I got a nice little 1/25 HP motor for $4.99 (American). This link Small Motors takes you to the Less than 1 HP Motors page where you can find many small motors, whether AC or DC. Try the 1-10 HP list as well since many people list in both places.

Excellent stuff, sasman. Thanks for the data. I may just go out and buy that book before I invest too much time and resources into this venture.

Hello Everyone:
This being my first post to this forum, I beg your patience. I have read every post in this thread and have ordered materials to build my first ball mill. I have not decided on the size of my jar or the size/composition of the media. I am leaning toward 1/2" brass rod, as I can acquire that locally (Salt Lake City) and don't need to pay shipping. And BTW, if anyone would like some brass rod, I am picking up 24 feet of it this week.
Is there any data that suggests spheres are more efficient than cylinders?
Thank you Burlhorse for your excellent use of mathematics in relation to the size and RPM of the jars. Did the AFN article offer and clue as to how the OPTIMAL speed is calculated? I am torn between 6" pipe for the jar and a 3-5 gallon plastic bucket. I certainly do not need the whole 5 gallons, but given the option why not use a larger container?
Thanks for your thoughts.
