I can assure you it does. That may not have been it's intention, but
it just worked out that way. Last fall I tried 3 different motors
(including a Speakeasy motor) and never could get the rotor to spin
fast enough without having the belt tension fairly tight (5-7 second
ramp up time, which I realize it the proper tension anyway) and the
coast to stop time was about 15 to 17 seconds. I assumed the cause was
the motor being mounted upside down, so the shaft was dealing with
more friction. In February I serviced the Leslie I use at church and
tore out the rotor cloth. At the time I saw no need for it. After
doing that, the same problem I was facing with my own Leslie, showed
it's head here too. I knew it couldn't be a coincidence so I was going
on the theory that the cloth had something to do with this. Last month
I put the new cloth on my own Leslie and let the Leslie spin at
tremolo speed. Same belt tension as before, same motor, same rotor.
With the cloth on, the rotor came up to proper tremolo speed. I like
the slow acceleration (about 25 seconds) so up until now, I was unable
to achieve this. The coast to stop time literally doubled. It went
from 15-17 seconds to about 40 seconds (give or take a couple of
seconds).

I tried everything last fall, from using different motors (if you
recall I switched the upper motor with the lower motor) to taking out
the entire lower rotor assembly and checking to make sure nothing was
hindering the rotating parts.

I once saw a picture of a Leslie where someone had put a rubber band
around the lower rotor.
