SawStop Revisited An Online Extra to Fine Homebuilding magazine By Tom O'Brien
SawStop inventor launches own line of safety-minded table saws
More than 2-1/2 years ago, we reported on an exciting new safety brake that could save the fingers of thousands of table-saw operators. Most of us are familiar with power-tool brakes that stop a spinning blade quickly to prevent injuries; this one stops the blade immediately to minimize an injury.
Briefly, the instant that the SawStop safety brake detects contact between a spinning blade and a finger, or other flesh-like object, the device explodes like an automobile air bag, bringing the blade to a dead stop within 5 milliseconds.
