What if you could stop a saw blade and prevent a serious injury? That sounds like a really good idea.
Today, that idea is protecting woodworkers in tens of thousands of SawStop table saws in North America and around the globe. SawStop are proud to say that it was their idea, but they are most proud that woodworking is now safer.
SawStop saws, besides being the highest quality and best featured saws in their market segments, feature the ability to detect contact with skin and stop the blade in less than 5 milliseconds.
But how does it work? The blade carries a small electrical signal, which the safety system continually monitors. When skin contacts the blade, the signal changes because the human body is conductive. The change to the signal activates the safety system.
The saw stops in less than five milliseconds, and angular momentum retracts the blade into the table. The operator suffers a small nick instead of an amputation or other more serious injury. The design takes advantage of the difference in conductance and capacitance, between wood and flesh.
The SawStop Jobsaw's 10-inch blade turns at 4000 rotations per minute (RPM). This means the circumference moves at about 2094 inches per second. Therefore, the blade normally moves at about 2.093 inches per milliseconds.
The SawStop story is about a small company with a big idea. The technology was invented by Dr. Steve Gass in 1999, and the business was started by Dr. Gass and three other friends.
In 2004 the first SawStop Table Saw was sold. In the years between then and now, our saws have saved thousands of fingers. The combination of safety, unparalleled design and craftsmanship has made SawStop the #1 cabinet saw in North America.
