DougIt reminds me of Howard Johnsons prototype I saw. The little tiny bits of hammer smashed magnets, carefully glued just so, in a gravel like array, along his tracks, where the car would go. It was like a scenic embankment, populated with chunky gravel stones, in a model rail road, large scale.He used early seventies five minute epoxy, rather than hot glue. It seemed to work just fine.Until I read up on it, I was unaware of how much consideration went into each and every one of those magnet crumbs, as to the position, and orientation.It makes you wonder, how did he read the magnets? A little hiker 's compass?In any event, he sure overcame the block wall, that any of us working with magnet motors, were challenged with. It was a blue bastard to overcome, but old Howard Johnson pulled it off, and made an, all magnet, self runner, back then. Too bad he messed with aluminium, and eddy currents, which he didn't know about.Cheers Warren

Hi Mick
Interesting description of Sweets magnets it reminds me of Bill Miller's description of his black sand cores; "random polarities" to the crystalline encased ferrite in the black sand he used
