as well as disks, Gary is also an expert in spinning lampshade design robots :P

Seriously though Ewan, listen to these people. Ive only built one spinner - Vortex, but it didnt seem to do too badly, so Ill assume I can speak with a little authority here.

You need to think about an axle at least 15mm in diameter. You need to support it at both ends really in bearings. Were just trying to stop you from seriously injuring yourself mate !
