For those of you that enjoy woodworking and still have enough fingers left to get to this blog, you may be interested in this new table saw that knows when it’s cutting something it shouldn’t be cutting.
The Sawstop system induces an electrical signal onto the blade and then monitors that signal for changes. The human body has a relatively large inherent electrical capacitance and conductivity- if the system detects this, the blade drops out in 5 miliseconds! Check out the video when the saw comes in contact with a hotdog..
Watching the video is worth the seeing-to-believing crowd! Pretty impressive!
