In his book "Shop Savvy" Roy Moungovan of Popular Science describes a flame cutting guide which has a "clockwork governor" which travels a constant speed regardless of irregularities in your pulling action. It is a magnetically mounted device. It's pictured but not named on p. 58 of the edition I have. What a great thing, but unfindable. Said to be a commercial product, I can find no mention of it on the Web or anywhere in the Land of Google.
- Anyone know what this device actually is, or where to get one?
- How could such a speed governor work?
