No need to throw the belt, just switch the power off to the pony and let
it freewheel.


I remove the belt, Gary, because it reduces the noise output
of the converter setup by about a factor of three. The
belt and pony motor spinning makes a fair racket.


My converter uses a 15 hp idler, and the pony is a 3/4 hp
single phase motor. Frankly, I can't tell the difference with
the belt on or off. Most of the windage is in the big idler.

Because the running speeds of the two motors aren't exactly
the same, there's a bit of a squeal when the big idler first gets
power and the pony is switched off (I have the switches
interlocked). But that's all.
