Cool!
Are there magnets on the ends of the "spokes" and on the "rim"?

Yes. You can strum the cables, and the magnets will vibrate in the air.

Thanks.

Hardest thing: polishing that stainless steel, especially after the HF ring roller put the teeth marks from the knurled rollers into it when rolling. The flat bar came in standard mill 2D finish. Starting with that, and adding teeth marks, it is an enormous pain to get it to reasonable finish...

Does anyone know where I can buy flat SS bars that are #4 finished?

http://www.kjmagnetics.com/ is a good source.

What kind of wire is that and how is it attached to the magnet - does the magnet have a hole in it? Neat project!

Hm. Interesting. Haven't seen it before, and yes, looks like his. I guess great minds think alike.

I took some stainless screws, and welded the cable to them (VERY carefully) then threaded the cable through the hole. The head of the screw fits nicely right over the hole.

Bruce Gray - well that's a bummer :) But then, it is a bit presumptuous to think this has not been done before.

Once again I have to make one. I teach a "teacher physics workshop" the next topic is magnatism. Any tips you can give or even part numbers.
Very cool looking. Thanks for posting.

I do alot of polished stainless work and have never seen #4 finish bar stock before, im pretty sure thats specific to sheet. What did you use to finish it? a nylon mesh grinder wheel and some 200 grit flap wheels would make quick work of that.

A medium scotch brite pad that mounts to a drill gives a nice and consistant satin finish - I've used it quite a bit on aluminum, but it should give similar results on stainless

So I had to use some 60-grit wheels to do that, then smooth it from there...

I found that if I wrap the bar in duct tape, 2-3 layers, it still is pulled through the bender, and the bender chews up the duct tape pretty badly, but no teeth marks. So I think I will do that next time.

so go from 60 to 120 to 200 then mesh wheel and polish, mirror finish everytime.
