Just to clarify, I never have to hunt for the footswitch to turn it off, 'cause unless it's a long cut, I just keep the heel on the floor, and the toes resting lightly on the switch, much as a pianist keeps the right foot on the damper pedal at all times. Maybe so many years of playing piano is where I developed that habit. The foot is in position, I just don't have to actually hold it down the whole time.
Also, I learned early on that it's a pain to have to chase the switch around, so it's screwed into the wooden floor of my shop. When I do demos at wood shows, some 2 sided tape will also do the trick.
I wouldn't use my kind on the band saw, table saw, router, jointer or planer, but the scroll saw is about the safest tool I own.
I'm not knocking those who use the deadman, just thought it was strange that Steve would clearly state that "you don't want the other kind", when many of us use and prefer them.
