Isn't that what a Japanese turner did to control the speed of his lathe when
he demo'd at one of the AAW conferences. He used a foot switch and clicked
it on and off to give the needed momentum(?) and revs to his piece in the
chuck that was attached directly to the motor. A whole body experience? I
think he was turning some sort of toy - a balloonist?.

Arch,

A Scot would just turn the switch on and off real fast, keeping the
rpms from building up and saving electricity.
