Homemade Spinner

Chris:

I built the TwistyGrip spinner  If you use the Belkin mouse as it suggests, the construction is very straight forward.

However, the weak point of the design is the superglued piece that holds the end of the shaft up.  Many many times my daughter or niece would push too hard on the spinner while spinning in Wheel of Fortune, breaking off the little superglued tab.  Eventually, it became unrepairable, and I finally removed it from my cabinet.

Well I built a doug hansen spinner, and the only thing I'd have to say about it is that if you're going to use any type of material to mount it on that's less than 1/2 thick, put a screw on top, and hold up the coat hanger pcb thingy via a nut on that screw, that's my plans on my unfinished spinner.

I have fiddled around with this design too...

The hard drive bearing I used (out of a Western Digital hard drive) had a #4-40 thread on the top.  What I did for a shaft is the following:

Take a 3/4" (or so) #4-40 bolt, and use a boltcutter or hacksaw to cut the head off.  Then, screw the bolt threads into the HD bearing top.  Finally, screw one of these into it for a shaft:

Use the 0.250 OD round threaded spacer...works perfectly as a shaft, and comes in lengths up to 2".  These can be purchased from probably any electronics supply house, including Digikey (http://www.digikey.com)

Hope this helps!
Terry.

Has anyone else found that a 4 - 40 bolt is too big?  The hard drive I used was from an old Power Mac and it's pretty much exactly like the one Doug used.  You can't really find anything smaller than a 4-40 anywhere.  Radio shack doesn't carry ANY....and they even gave me kind of a dirty look for even asking about bolts in an electronic store.
