Sounds like a very good setup. I also have a gear reduction motor from All Electronics. I work within driving distance of All Electronics and so they are my first choice for surplus. There is another a little further away called Apex surplus that I also frequent and I have Harbor Freight locally. Guess I got it pretty good in that arena. I was going to put the o-ring beneath the shrink tubing but if it is not necessary I will skip. Thanks for the good info. - Steve N

So far no need for the O-ring around the center, they spin well as-is. My bars are about 3/4" to 1&1/2" long overall. You could slip them into PTFE (teflon) tubing as well, or use two of the cylinders oriented N-S - N-S in a tube, and/or put a small ring of polyethylene or whatever over the tubing (over the magnets) . . . . I'm not sure I trust Viton or Buna N (O-ring materials) in my CS, but I'm cautious. Beneath this my stirrer motor is an el-cheapo gear reduction (like an electric clock) motor from AllElectronics, turns about 40 RPM, stuck a piece of 1/4" thick by ~1" dia. poly plastic, and counter sunk two little disc magnets into that. Works for me . . . HTH, Malcolm On Sat, 2009-05-02 at 10:51 -0500, Norton, Steve wrote: > Since I brought the stirrer here is what I was planning to make.
