I am wanting to build a ballmill. I have a few ideas kicking around in my head but would like some ideas.



I found your thread on another forum Gus and was excited to see pictures and read up on it but your posts were gone.

My idea is to use a 20 gallon air tank and mount on each end garage door torsion tube bearings. I have the bearings , bearing plates , and the torsion tube to use as an axle.
I am thinking bicycle chain and sprockets as the drive train as they are easy and cheap to obtain.

A garage door opener would be great as it is geared and is set up with sprocket(not same chain as bicycle though) but will not work! The motor is not made for constant use.

Any ideas are welcome.

Thanks
Joe
