Nice video! Text plus multiple scenes. You must have a video editor
of some kind.
I'm surprised the thing held together that well, considering the
imbalance from the U bolts. It certainly does demonstrate the motor
works in that configuration
I like your motto!
Best regards,

GENTLEMEN! I give you... this THING!
Yeah, it's a terrible, and probably quite boring video. And the hands holding
the contraption belong to yours truly.

Yes!

Also of possible related interest is that I tried a regular steel
ball bearing and a stainless ball bearing on the same aluminum shaft
and it appeared the torque was abut half that for two steel bearings.

U bolts on outer races ... OK

No.
Things are just... things are hard. Life.
As for your "stat
Stephen, note that although some stainless steels are not magnetic,
others are. The 300 series aren't, the 400 series are.
Also it seems to me that the ball on track system, which we agreed
should be equivalent, might be more convenient than an actual BB for
the magnetic vs not magnetic tests you'

This works like a charm.
I may start a few experiments along these lines myself, if I can find the time.

Here is another possible experiment which could indicate definitively
whether the inductance of the outer bearing race is playing a role.
Unfortunately it also seems likely to be harder than it appears at first.
Run the experiment with stainless (non-magnetic) bearings, and

However, I believe I have found some reasoning which implies something
like that explanation must be correct, and I've also found a "fix" to it
to allow the explanation to go forward, and I think there may even b
My explanation turned out to have a gaping hole in it.
First, background:
-- A wire carrying current has a "self inductance", which is fixed
per unit length.
-- The self inductance of a wire is larger for a ferromagnetic wire
than a nonmagnetic wire, so the effects described here are l
