Those posts are so old that what you're seeing can probably be accounted for by the half-life of a post!

What is half life of a post?

About 1/4 that of Uranium235

This stuff is now so out of date that the original site listed has been taken over by Spammer Cyber Napping Scum, and the rest of the information is pretty much completely wrong.... except for the cheep spinner...

Anyway, back on topic of building a good, inexpensive, spinner.

I made an encoder wheel for my first spinner using a 3" hole saw and sheet metal. To do this I cut a 3" circle (which has a 1/4" center hole) out of sheet metal, attached the encoder wheel template which was printed on sticker paper, and cut the notches with a dremmel.

But this encoder made of sheet metal was flimsey, a thicker sheet metal would have been difficult to cut, and either way an expensive hole saw and arbor must be used. While that is fine for me, because I have that, it would not be cost effective for someone who doesn't have that.

So I started thinking of where a person could get a 3" circle with a 1/4" center hole - it had to be rigid yet easy to cut - viola! A mini CD with a washer in the middle! A mini CD is 3" in diameter (8cm), but it has a 15mm center hole. I found a flat washer that measures 14.5mm O.D. (0.56") and 1/4" I.D. at the hardware store. "USS Flat Washer #10 by Midwest".*

I was curious if a CD could be cut with a dremmel's cutting disk so I cut notches into one. It worked fine and did not crack. I had to sand it after but the whole thing took a leisurely 10 mins to make.

The washer would have to be glued in the middle - I will tape the washer in place from top, flip the disk over, and apply superglue around the outside of the washer.

Once finished i will spray paint the CD flat black

When the spinner is done it will only have cost about $10 :)

What do you think?

Cheers,
Craig

*note, Midwest makes 2 different #10 flat washers, one of them does not have the correct O.D. (outer diameter)

Cool !!! That's what this forum is all about.... a bit of inovation and do-it-yourself stuff. It's kind of gone out of the window here in the last few years, with people just assembling stuff from off the shelf parts more often than not. I'd guess you could get a lot more teeth onto that wheel by using a slitting saw in the dremel instead.
