after a bit of trial and error bending, the motor took off. What really made it work were the 3/4" x 1/8" NdFeB Rare Earth magnets that I bought off Ebay. the supplier is http://www.forcefieldmagnets.com, ebay seller = "pie"

Here is a link to a YouTube video showing the motor in action:

Easy motor - not so easy?

Okay, this is my third try and I've been at it for over an hour. The spiral/balance thing is hard!! Every once in a while I get a little hint of self-generated motion but ... any hints on winding up a good spiral? I've tried using a just a bit thicker cylinder but the fine adjustments always end up askew.
