Check this out. Amazing!

YouTube - Time Warp SawStop Table Saw on Discovery Channel

I've seen this demo'd at a couple tool shows...it REALLY works! :thumbsup: :thumbsup:
Two "thumbs" up. ;)
Years ago, my father-in-law lost two fingers to a saw. And a guy I work with recently cut off his thumb at the 1st joint during a home improvement project.
This safety device should be standard equipment on all table saws IMO.

We have one of these in our district... amazing, one problem is that if you react to fast to touch the saw after it stops to say... align the curf for measurement it will trigger the saw stop.... So we were told to count to 10 after it stops before we touch it.

We just got one at work. No one has tested it yet. :D

I have heard wet wood sets it off though.

Why did he dip his hand in the cooler before touching the blade? Does it have to be wet to work. Also he put his finger in there very slowly, what happens if you touch it quickly like you might in real use? Looks like a great idea, I hope it really is as good as it looks.

Bill,

While the design is effective for stopping injuries, it is not cost effective for small contractors. I would rather spend two days training someone how to be smarter than the saw than I would want to add another $300 to the price of an already expensive piece of equipment to make it idiot proof. If you are on a job and that thing goes haywire and stops because you have wet wood, it could shut down your production until you pay the $250 or whatever it takes to make it operate again.

I have been using a table saw everyday for 20yrs and haven't been bit severely (yet).

And I hope that continues!!
In my line of work (machinist) over the years I've found that in most cases, it isn't the young, inexperienced employee that usually gets injured. It's the old timer...been doing the same thing for years and becomes complacent and inattentive. As a supervisor, safety always has been my number one concern. I want each of my guys to go home at the end of every day to their families and not by way of a hospital.

Granted, if this blade safety system is too sensitive to wet wood, that should be addressed. But, the basic idea is a good one.
Cost?? In my industry, we'd spend a billion dollars if we could prevent one person from being injured. We get no second chances.

According to the video, anyway, the cost of a new collapsable stop and blade is $60. If I had business, big or small, that required use of a table saw, I'd have a dozen of the stops and baldes in reserve, so that even if it was a false trip, I could be up and running lickity split.

From a strickly bottomline basis, the extra parts would more than pay for themselves by avoiding one accident. Medical insurance, worker's comp claim, lost time, etc. Especially for a small business, imo, where every employee is critical to completing jobs! No back-up employees ready to jump in.

Not that the cost of the blade is bigger than the cost of an employee losing a finger, but I can tell you this, I spend over $100 per blade for my table saw. That cheap blade they are claiming isn't even close to being good enough for fine woodworking.

I am on the fence with this one. I do agree it is an excellent safety tool, but on the other hand it is extremely sensitive to wet wood as tht is what triggers the stop. It could get incredibly expensive for a contractor to keep replacing the stop and blades everytime a piece of lumber went through that wasn't thoroughly kiln dried.

Do you normally use wet wood for fine woodworking?

We use the saw at work to make shipping crates. Many times it's an OT situation where anyone in the shop who accepted the OT will be using the saws. There is no way to predict the level of saw skills of the person using it.

The new CEO came in and toured the shop and that saw was his prime concern. We had a perfectly good Craftsman saw. Maybe one year old. The CEO said get rid of it and buy the Saw Stop. Maybe he owns stock?? ;)

Yeah, I have seen many old timers get bit. While I do get a little on the "don't do this at home" side with my saw at times out of necessity, I usually do my best to follow basic common sense when it comes to operating a power tool. You always have to have respect for the tools. They cut you and it won't bother them in the least.

All of the accidents that I have seen over the years were out of complete stupidity. I watched one guy cut the same thumb off twice with the SAME saw, with about 10 yrs in between incidences. I just shook my head and took the idiot to the hospital for the second time.

Thanks Dean.. I thought I was having Deja Vu. hahaha, I was wondering where I had talked about this saw before. :D

Like they say "You can't fix stupid".

There are just some out there who should be using these:

It has happened to me on more than a few occasions where I have went to my local sawmill and picked up a load of rough lumber and ended up with numerous board feet that didn't sit in the kiln long enough. Remember they don't moisture test every board in a kiln, they test random boards. It is quite common to get lumber that hasn't dried down enough yet.

So to answer your question, no I don't use wet lumber, but in the process of planing, jointing and squaring, I have run plenty of wet lumber through my saw only to discover it can't be used on that project and has top wait to dry.
