Arch,

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

I'm married to a McAmis. I have witnessed frugality in action.

As shown in Del Stubb's video, increasing the lever's range, adding foot
pedal control and a dowel to keep the belt from being thrown away from
the back of the pulley thus tightening the front might all improve my
Scotsman's VS/clutch, but I need it so seldom why bother?
