Anybody have good ideas for what I could use for bearings, to make a spinner that spins nicely? I've checked hardware stores and all I've found is funny looks and confused expressions from the sales-robots. :) I liked the hard drive idea but I don't think I have any old hard drives, and our local "buy really old computer crap" store just went out of business. |

Trackball bearings work pretty awesome. Some high grade Rollerblade berings can as well... but, the shaft size will be incompatible with most things. All in all though... its easier to go with a prooven quality spinner such as the one at http://www.slikstik.com/. Youll probably save yourself a lot of headaches, mechanical failures, and a lot of wasted time. I speak from experience in this regaurd. |

I'm thinking about it. It's the cost of them mostly. I'm too poor to build this machine. :'( Maybe that'll change when I get out of college. |

There are a couple of examples of projects like that in the Controls section of this website. They spin really nice and I'm sure you can find a dead hard drive somewhere. If you go for it, make sure you get several hard drives as not all of them have motors suitable for this application. Some of them have part of the motor built into the HD case and you cannot remove it. Some others, don't have spinning parts that show up on both ends of the motor and are no good either. Good luck. |

I just finished my home made spinner. Used motor/bearing parts from a 6gig HD that crashed. Super glued some large washers on the bottom for weight. Threaded a #4 thread shaft, some #4 nuts and washers, and a rubber caster wheel for the knob. Really spins good........ I guess I really should take some pictures of the darn thing..... I'll try and do that tonight. <update> Took some pics.... not real great, but hopefully they will help. http://www.angelfire.com/comics/nighthawk2099/images/mame/spinner1.jpg http://www.angelfire.com/comics/nighthawk2099/images/mame/spinner2.jpg http://www.angelfire.com/comics/nighthawk2099/images/mame/spinner3.jpg |
