    Somewhere, I suspect, the magnet to a Kundo clock I'm working on attached itself to some steel......I can't find it! It's the round bar magnet to a Kundo battery operated clock. Length is approximately 39.50 mm. long (brass spacer is already inside, that's where I measured from to the outside of the bar), and less than 5.30 mm in dia (measured diameter of the hole it slides into. If you have a spare, I would be interested. Please contact me via a PM message on this board. Thanks so much!.................................doc

    Thanks John for the reply. But I won't need one now! I sat at my bench this morning, just wondering where it could have gone and what could it have attached itself to, when I looked up and spotted my two cans of acetone and denatured alcohol. Checked the acetone, no go, pulled down the alcohol, voila! Stuck to the side at the bottom of the can. Whew! I was really beginning to wonder about my sanity on this. Anyway, thanks again for the reply, I'll keep the reference you gave for other magnets........................doc

    Lucky lucky Doc. If my memory is right, the magnet has a red dot on one end. What I don't remember is the orientation of the magnet slug.

    At least one user/experimenter reported adding a tiny but powerful neodium (sp?) supermagnet on the end of the cobalt-iron magnet and noted an increase in pendulum motion. The effect on dry cell life was not reported.

    The red dot goes on the inside of the bar, so that is the end closest to the coil. I was working on one of mine last night and made note of that while disassembling the pendulum.
