This company came up with a technology to save woodworker's fingers
SawStop is the difference between a cut and an amputation
We admire the artistic creations made by woodworkers, but the risk of working around a lethal weapon is always daunting, even for the most cautious woodworkers. A careless mistake could result in a time-life pain and trauma. SawStop, an Oregon based table saw maker, came up with a safety system that had saved thousands of fingers.
From the outside, the product looks no different than other table saw on the market. But the spinning blade will miraculously stop the millisecond it comes to contact with the skin, leaving at most a small nick that could be fixed with a few stitches instead of one or more missing fingers.
The below are how the finger-saving technology works:
1. Monitor and Detect
1. The blade carries a small
2. When skin contacts the blade, the
signal changes because the human body is conductive.
3. The change to the signal
activates the safety system.
2. Brake Activation
1. An aluminum brake springs into
the spinning blade, stopping it in less than 5 milliseconds!
2. The blade’s angular momentum
drives it beneath the table, removing the risk of subsequent contact.
3. Power to the motor is shut off.
Resetting the saw yourself is easy. Simply replace the blade and affordable brake cartridge and your saw is operational. The entire reset process takes less than five minutes.
