About a month ago there was a post that included mention of a deadman switch on a table saw. Back then I promised that I would post some pictures of some of the modifications we've made to the stationary tools on my ship.

Sorry for the delay, but it's been a little busy out here with the weather this winter.
The switches are simply momentary contact switches from Grainger, I think they were $20 or so. They basically parallel the stop contact on the magnetic starters for the motors. You could use a sustained contact 'stop' switch if your equipment doesn't have a magnetic switch, just remember to turn the main power switch off before you reset it. The pictures are pretty self explanitory.
