Neat safety device for a table saw

pretty big pucker factor tho...

this is old, but still great.

at 4:18 you can see blood spray out

Isn't there some big consipiricy theory about this thing? I've heard about this for years and the guy that invented it is like the guy who invented air-bags or something - and the major saw manufacturers didn't want the govt hearing about it because it made so much sense, and added so much to their prices? I don't really care one way or the other but I appreciate the technology.

It's a great idea, but I see two problems.


First off, your hands have to be wet apparently to make them more conductive. Notice how he had to dunk his hand in a cooler to wet it first.

Sawdust creates an extremely dry environment which would make your hand quite possibly less conductive.

Sure, your hand would be salty and wet anyway after it goes through the first few layers of skin, but who wants that?



Second, if it's conductivity that sets it off, how about just a bead of sweat? Every time you happen to have a stray bead of sweat land on the blade, it costs you $60.


It's a neat idea but it makes the tools more expensive and less useful.

I don't think we need more safety so much as we need less stupidity. Just my opinion anyway.

That sums up what I'm thinking too.

The wet hand only assists in proving his point. Once the blade rips into the finger and comes into contact with blood, it would shut off... A big cut is an improvement over a lost finger.

Also, the bead of sweat thing wouldn't work. It works on your body, because the current enters your body and dissipates as it tries to ground itself. The bead of sweat doesn't ground anything, unless it lands in the perfect spot at the base of the blade or something like that.

I could see this technology having a very good use, in places like high school wood shops. That being said, the fact it is so damaging to itself means only the most safety-conscious workplaces would ever install these.

that's cool, but i'm just gonna pay attention and not cut anything off

 

[xkotyx]

i saw this a couple years ago. we were actually talking about it at work just the other week

 

[adsm08]

I think this is a great idea. And yes, I'd probably pay the extra for it. As someone with a wife who loves to do wood work and who both want kids, yeah, I'd pay for that.

I think it badass, I belive do belive that schools should have'em there were plonty of horror stories going around from when I was in shop class in school.
I myself maybe not for the fact when I buy tools I try to stay with the name brands but I also go with who has the cheaper version and 60 bucks less for the other guys I would go to them. Not Only that I would get the one that was defective. That always happens for me there could be ten of the same item on a store shelve I can sort though them looking for the best undamaged package ect, ect. I'd get it home to find out it was broke, never fails.

amen!

The bead of sweat doesn't ground anything, unless it lands in the perfect spot at the base of the blade or something like that. Lets say you're sawing something, resting your hands on the wood you're cutting and your shoes are keeping you from grounding out, and you're not touching anything else. Seems a little hard to differentiate your finger from a bead of sweat in this scenario, since neither is grounded. So either the sweat would trigger the device, or your finger would not. Do you wanna find out the hard way which one it is?

That being said, the fact it is so damaging to itself means only the most safety-conscious workplaces would ever install these. Yea', the kids would start putting their fingers into the blades being jackasses like teenagers like to do, and cost the school lots of money to replace the damaged components and god forbid the device fails to operate for whatever reason and the kid loses a finger

My overall point is I'm tired of people basically saying "You don't need common sense if you just buy my product..."


I don't currently own a table saw, unfortunately all I have so far is a band saw. My favorite safety feature is that the switch has to be pulled instead of pushed, so nothing can accidentally bump the saw and turn it on. Other than that, if the saw is running I should be giving it my undivided attention until I have completed my cut and turned the machine off. If you cannot respect a tool that can rip you limb from limb if you get careless, you should NOT be around it.
