I hope that's sort of a joke.

The answer should be: none.

A friend hurt himself pretty bad a few years ago with one of those things -- could have died, lucky he didn't, and darn lucky he can even play piano again. It was bad.

P.S. Do you tech guys need to use one of those???

I've edited the post.

My apologies. No malice intended. I also know several folks who were injured with table saws.

This is why I posted the link.

This is also why I keep my eyes open for things like this.

Regular techs probably would have no use for a table saw. But, rebuilders could.

I haven't used this saw, but I've heard about it; it's been around for years. The hot dog demo is pretty convincing.

It may not work 100% of the time, but any time it does work, it's 100% better than any other table saw.

There's a whole story about how manufacturers declined to produce it, because it would make their other models seem unsafe.

Hi Cy,

I didn't know this was old news.

It's a pity they decided not to mass produce this. It seems that the technology could be applied to other power tools as well. We could all have a much safer shop environment.

I've seen this a while back and it would certainly be worthwhile for those people who are somewhat clumsy or forgetfull around machinery. I doubt it would help for the ones with long loose sleeves, neckties or hair though. There is a downside to ultrasafe machines also, it allows operators to develop lax or unsafe habits around them. Similar to hunters relying on the mechanical safety of their firearms..Murphy's Law usually pops up.

A revolutionary product. Jenn and I are ardent woodworkers. We have seen live demos on this at several woodworking conventions and exhibitions. It has been around at least five years, maybe longer.

I have one of these. They are amazing saws. If you must use a table saw, this is the safest on the market. However, I still use all my guards, push sticks, featherboards. I take no chances with my fingers. No other saw has this technology. The other manufacture refused to adopt it , so Sawstop started their own company.

We have some of these Sawstop table saws at the plant where I work. I don't think the feature has ever been needed. If it does trip you have to replace a $69 part which is nothing compared to a trip to the ER. But even if it does not detect jewelry, long hair, etc. (which should not be near power equipment anyway) if a body part is drawn into the blade it will detect that.

But generally my experience is that 90% of the accidents happen to 10% of the people. If someone is missing a part of their body due to a power tool accident, they probably have other parts missing, or at least a number of scars and stories.

I checked the Sawstop web-site. There's a dealer about 45 minutes away from me. I'm curious as to the price difference between a Sawstop and a regular table saw. I'm also curious to see if they are using this type of safety feature in bandsaws and other power tools.

I quickly looked over the Delta Machinery / Porter*Cable site. I didn't see any table saws with special safety features. But I just scanned the site. I dig in deeper later.

Thanks for all the info! smile

Exactly, and those are just the people that wouldn't buy a saw like this.

In the end, it's always best to be careful around powertools, so if you need a new saw I don't see a reason not to get the Sawstop. I don't think it's worth replacing an older saw for this if it still does it's job well, though.

All in all, nice find, I've seen it before but it might be helpful to people who didn't see it yet, and are in the market for a new saw.

It is not just the $69 part that needs replacing, but the blade as well, as I recall. However, it is a lot like an airbag in that respect.

Small price to pay for saving a finger, though!

I'd imagine the $69 part, the blade, and the blade shaft and bearings would need service.

Just yesterday my boy wanted to turn the table saw on for me. I lectured him severely and then gave him a demonstration of how dangerous a table saw can be by tossing a small scrap of wood onto the spinning blade. It flew across the basement and pieces went everywhere. He thought it was great. Sigh...

Have the Laguna TS and the riving knife really adds to overall safety.

"8.3 -- Nothing is foolproof to a sufficiently talented fool."

Although I didn't look into the details I presume the saw detects flesh contact with some sort of device that completes an electric circuit, provided the operator does exactly whatever is necessary to make it work.

When I worked in a fab shop, we would teach the newbies the dangers of some tools. We would take a white cotton glove, put ketchup packets and hotdogs into the fingers of the glove. While bending some metal stock to the danger point, we would put the hotdoged glove in the correct (wrong) position and continually the bending. The metal stock would slice the glove, hotdogs and ketchup packets and would give you a very graphic display of what would have happened if your hand was there. Been twenty years since and I can still see it.

When I worked in a machine shop years ago we had a poor chap that let his long hair get wrapped up on the spindle of a (large) double wheel pedestal grinder. The cast iron guard for the wheel was easily busted with the impact of his head.

The machine was dismantled and left on the floor as is where the employees walked in for their shift. A stark reminder to concentrate on safety and leave distracting emotional issues and foolish bravado at the door.

Emmery:

I am guessing that it is similar to the lamps that turn on when you touch them. It probably senses the electrical capacitance of your body. No need to complete what is thought to be an electrical circuit.

Monster:

That wouldn't work either. My boy likes ketchup and hot dogs. laugh

We had the same thing happen I was in Junior HS (and dinosaurs roamed the earth...). Except the poor kid caught his hair in a drill press. Yup... They left it there as a warning.
