Near impossible to replicate

[raburgeson]

The Johnson motor is a project for a doctor of physics. The materials are extreamely expensive. The alignment of the magnetic field in each magnet must be perfect. The tolerances of arraingment are critical. This is a good subject to avoid trying to replicate. I hope noone has gone broke playing with it. Since 1980 I have viewed only one working (well mostly working) model. The man was from the Buffalo area, can't tell you his name. I supposed at the time he was invited to show his device by the classic and antique car club here. He had it mounted in a customized bicycle frame. He had major problems! It was not a self starter (he had to push it to start it). Variable speed control didn't work ( there were 2 adjusted spots in would run in and there was only about 10 rpms difference in the 2 positions it would work in). And, lastly he was only producing about half the horsepower it was supposed to according to Johnson. It however did work. He'd ride it around a little and stop to chew the fat. The cars weren't present and it wasn't enough to hold my attention to long. It is an excellent example of what's possible though, it's not practical for most of us in here to attempt this project. Can I get any flack from you guys about any of these new things I see you've posted. I think we should have a drawback and pitfall area. You talk about what your doing, you don't talk about difficulties or why you think it failed.
