I have to disagree on the SawStop. If it triggers, you have to replace a cartridge, about $70, and the blade. The blade gets embedded in an alumium chunk and stops within a tooth rotation and retracts beneath the table. Super cool to see, but priceless if it saves a finger or worse. Or that of, say, a son. It's the first tool I'll purchase for the shop once I get to that point. All the reviews are outstanding, not only have the safety, but also a top notch cabinet saw. Yep, it will set up back an extra few bills, but next time you're talking to your buddy and notice the digit missing on his finger, ask yourself how much is it worth. Are must "accidents" due to carelessness or stupidity? Yep. Are all? Nope. And when it comes down to it, does it matter? Yeah, I agree, it does. But then again, it's a whole 'lot cheaper than a trip to the ER, as stated above.
My understanding is if you cut in wet wood, you may trigger it. So you can override the safety mechanism with a key switch if you desire. It works by sensing the capacitance of the material being cut. Wet, like me and you, and we change the frequency of a signal applied to the blade. When it changes enough, it triggers the mechanism.
It'd be one thing it if was a crappy saw with a safety...but they made a top notch cabinet saw that rivals all the others. Have a high end commercial version, a nice serious hobbyiest cabinet saw, and I think they annouced a cheaper contractor style.
For my 10 fingers, and especially when I think about my wife and son, not sure I could purchase a better insurance plan. Just imagine if such a thing was mounted to our chainsaws. That accidently swipe through the leg, foot, arm, head, whatever....wouldn't be a problem. Yep, that's what boots and chaps are for, I agree. But for those of you with stitches...wouldn't it have been nice to buy a new chain and $80 for a new module instead of paying for 30 stitches? Sh!t happens...might as well prevent it if you can.
Off the soap box now.
