Re: Spinning Cylinders

While we have a machine shop I think our method could be done with just a drill press.

We make a free spinning roller (Al tube with bearings pressed in the ends) attached to the frame using hex head cap bolts with the heads cut off.

Mount a gear or pulley to one end with 4 screw.

The gear method requires a motor mounted closely to direct drive the gear on the roller. The pulley allows for a remote motor mount.

Having the drive right on the end of the roller only takes up room that the balls wouldn't go into anyway.

Hope that helps.
