There was an error working with the wiki: Code
Variations on the OS:Screw-Magnet Motor design, first reported by xpenzif on Oct. 15, 2007.
The objective is to have the main project focus on replicating and characterizing the first working device. This page is for spin-off design consideration and launching.
Status : This project was posted on Oct. 15, 2007. As of Jan. 15, 2010, we know of no successful replications nor validation of the original device. On Jan. 13, 2010, we were given OS:Screw-Magnet Motor that suggests fraud. -- SilverThunder 14:49, 15 January 2010 (PST)
Hans von Lieven suggests that horseshoe nails might work, as they are the right shape and composition. http://www.overunity.com/index.php/topic,3482.msg55076.html#msg55076
Troyd1 suggests that maybe cement nails. "They are tapered and should be able to be bent to conform to the cylinder." http://www.overunity.com/index.php/topic,3482.60.html
Freezer suggests "cutting triangular pieces of a metal sheet" http://www.overunity.com/index.php/topic,3482.60.html

Screws aren't really necessary, you can build one by cutting washers in half and grinding one side down. Here's a picture of part of a tiny spindle for a desktop toy using the washer design.
This design makes it easy to adjust the angles the washers relative to each other less change in angle=more torque, more change in angle=more speed, less torque(this can also be accomplished to a degree by changing the magnet arm angle).
This design uses a lot more magnets. I recommend a shaft made from a non-ferromagnetic bolt.The following diagram was proposed by Jason Owen.
