Default Fingers too close to the whirly thing

You may have seen this. . . it is interesting.
Wonder how it tells fingers from wood? It looks like it takes 6-7 teeth before it stops which still could cause some serious damage.

Not a bad idea. It looks like to me they use an explosive device the release the brake.

Hi Steve, I believe the Saw Stop uses electronic technology to detect the difference.

A wet piece of timber will set it off.

Steve, I've seen it up close and personal.... a woodworking store in Detroit had a demo of it a couple of years ago. Amazing technology, and it DOES work, just like in the video clip. Expensive initial purchase, and expensive when it works... blade is toast, as is the mechanism that stops the blade. But, it's still cheaper than the alternative.....

Mike I think that anyone who wanted to use this should not be discouraged from doing that, Me I would never use anything like this, I doubt that it would save a finger anyway, at what point does it kick in? Does it kick in when your finger is say a CM away, every accident that I have ever seen happened very fast, there was no a slow build up where the hand was inched forward a bit more and then a bit more so that when it was just a cm away then the device could kick in, me I would never believe that this could 100% stop the saw blade from cutting off your finger when your finger is a cm away and moving in fast, this is a fake solution and there is no solution better than keeping your eyes open and your fingers away from any fast moving cutter and I personally would not want to ever think that, "Its OK Neville to get close to the saw as the saw stop will save me'. The proper solution is to operate the saw, or the router, or the angle grinder, or the lawn mower, or the chain saw, properly, how do you stop yourself from cutting your leg off with the chain saw? You do that by showing dangerous tools respect, and me I would never want anything between me and any tool, I plan to keep my eyes open and use good trade practice and I would say to anyone who thought that the saw was so dangerous that they needed this, to go out and buy a nice pocket knife and take up whittling. You know when cars were first invented then anyone who owned one had to pay a person to walk along in front of it ringing a bell and waving a flag, and that never did work in regard to stopping anyone from walking under it wheels, what worked was to educate people to keep there eyes open and every time that they do then they don't get run over.

Hi Steve, I have A SawStop and would not operate another saw. I had a small board kick back and the brake immediately stopped the blade. I thought the saw had malfunctioned. I unplugged the saw and was looking at the blade/brake (the blade immediately drops below the table top & the motor stops). Then I notice a small amount of blood (about 2 drops) on one of my fingers. It looked like I had scraped the skin with a fingernail. The blade and brake were shot. I contacted SawStop and they said if I sent them the brake they they could read the computer chip to see what happened & would send me a free brake. Best piece of equipment in my shop. I have never understood the argument for not getting a SawStop. If you are careful you want get hurt or that since you have a SawStop you will take more chances. I don't buy either argument. If I have seat belts in my truck I don't take any more chances with my driving than without seat belts. Even if I am the only vehicle on the road I wouldn't take a chance of driving without the seat belts. And if a person is concerned about the cost of the saw I tell them to contact the nearest emergency room and ask roughly what would be the cost if you came in with a couple fingers that were hacked off. Then compare that with the price of the saw. Malcolm / Kentucky USA

Neville, the brake is triggered by contact with your skin and it is so fast that you will not realize you made contact until you see that the blade is stopped below the table.

I have this visualization of a red zone around the blade of any saw. It is about 6-7 inches in diamater. I cannot bring myself to move my hands any closer than that, ever. I also use a Grriper for all cuts where I'm not using a sled. I understand the idea of the saw stop, but I often work with high moisture redwood for outdoor projects, and if you forget to turn off the Saw Stop cartridge, wham, there goes a blade and the cartridge. I do such projects all the time and I am certain I'd forget now and again. So I use great caution, eliminate all distractions, plan every aspect of a rip or cross cut before I even raise the blade above the table. I like the Saw Stop idea, but the model I can afford is not a cabinet saw while my Laguna Fusion is. I respect anyone's choice of gear, I just want to have the option to make a choice. If I had a commercial shop, I'd buy the more expensive SawStops just for the liability issue and the safety would be a bonus.

It is a nice feature however pretty expensive. If I had to get one of those I would not have a saw as it would be more than I would be able to put into a hobby. Hiring someone else to cut your wood is always a safety option but it would not be much fun. Being electronic it could malfunction as easy as a guy that puts his hand into a blade. The only way you would know it did not work is after your fingers are gone.

If you do not think electronic things will fail, why unplug your saw or router before changing a blade or bit? Just my opinion based on my situation and experience, yours may be different.
