Fidget Spinner *LINK*
Ed Davidson
Just finished my first ever Fidget Spinner...made from African Pink Ivory and Blackwood, using a low grade ABEC-5 skateboard bearing. I'll use a higher quality bearing on the next attempt. Click on the link below to view a short video.

That's very interesting, Ed. I've never seen one of those. I can, however, imagine my fidgeting with one during a conference call. I'm sure it could become addicting (and might even tend to increase the attention I pay to the conversation, rather than allowing my free fingers to check email, cruise the internet, and such).

There are lots of people making these little ball bearing finger-spinners out of CNC machined aluminum and 3D printed plastics, but I've never seen one made from wood. Yes, playing with them is addicting. Just bought some better quality ABEC-11 bearings off eBay...tic-tic-tic, waiting for the postman.
Were the cheap bearing noisy?

I would think a self lubricating bronze sleeve bearing and polished shaft would spin just as smoothly with no noise.

Dick, the only skateboard bearings ("608's" - 7/8" diameter) I have experience with are the ABEC-5's that costs around $0.70 to $0.80 each on eBay...and they are completely noise-less. The ABEC-11's I just ordered were a little more expensive (about $1.10 each), but are suppose to be made to much tighter tolerances.
From what I've read and seen 1st hand so far, all of these large bearings come packed with heavy grease from the factory, and must be cleaned and re-oiled to spin quietly and freely.
