Table Saw Invention

Wow, thanks for sharing the video... absolutely incredible... 8)

Please post a video when it comes in.

I'm also confused by this post, Stu.


As for the invention, I think it's pretty cool. Not sure if it would work with a dry finger and I don't think many people would cut with damp wood anyway so that shouldn't be much of a problem. I still think it's implemented pretty well, it retracts and stops damn fast

[boyntonstu]

One doesn't routinely place one's fingers very close to a running chainsaw blade, lawnmower blade, or snowblower blade.

Unless one is exceedingly stupid.

Add my saw to that list.

However many a leg has been cut with a chain saw.

My machinist friend stupidly cut 4 fingers off his hand clearing snow out of his blower.

"Each year hundreds of people suffer maiming or amputations
of their fingers or hands from the improper handling of a snowblower.

It is the purpose of the Hand and Upper Extremity Center and the
American Society for Surgery of the Hand to provide you with patient
information to help you avoid these injuries during the winter season.

Injury Profile
Average age — 44 years
Sex — Male
Dominant hand — 90% of injuries
Amputations of tips of fingers
Middle finger most commonly injured"

"Nearly 210,000 people—about 16,200 of them children younger than 19—were treated in doctors’ offices, clinics and emergency rooms for lawnmower-related injuries in 2007, according to U.S. Consumer Product Safety Commission reports."

Incredible invention - Are you throwing out your table saw and replacing it with SawStop?

[MrCrowley]

No, I don't even have a table saw.

I said it was a cool invention, not that it was any use to me or that it would make me change my current table saw if I had one.

Why are you so hostile, not only about your inventions, but about other people's? Chill out, it's a damn cool invention and it works well even if it may have little practical use (not that I'm saying it doesn't).

Just because more people like this invention than your invention doesn't mean you have to troll the thread.


edit: BTW Stu, this is the last time I let you off with a double post. Next time your second post will be deleted without warning. We've had this discussion long before. If you don't like the rules, leave.

lol i linked it in stus upside down saw thingy thread.

[boyntonstu]

So, is damp wood an issue or not?

[Crna Legija]

iv seen on the loging show on tv, the men using chansaws were nylon pants that if cut clog up the clutch/gear part of a chainsaw with 0 dmg to the persons leg. and if you put your finger withing 10cm of a moveing lawn mowers blade you deserve a missing finger.

Would you expect to find the average person trimming trees in his backyard wearing nylon pants?

" if you put your finger withing 10cm of a moveing lawn mowers blade you deserve a missing finger".

Then why the need for SawStop?

In my invention, I never get my fingers within 25cm of the blade.


The other issue, which SawStop completely ignores, is kickback and throw- back.

There is also the element of unintended consequences.

You have a SAFE saw, so why not get close to it?

Do electronic sensor circuits ever fail? Oh oh, lost fingers.

Notice how people duck when they are under the rotors of a helicopter when they are more than 3 feet over them?

They see the danger and they want to be as far away as possible.

Is there an issue Saw Stop when wet/damp wood is delivered by an open truck to a work site?

The way the SawStop is designed causes me to think the blade arbor could bend as a result of the sudden stop by an asymmetric brake....but still a very clever device.

[irisher]

It would not surprise me if the resistance that the sawstop was activated by was limited so that only something with resistance equal to or very close to flesh would trigger it. This type of limitation can be seen on many touchscreens or trackpads where a finger will be recognized but metal will not. This would prevent the saw being destroyed every time a single drop of water happened to land on the blade.

I don't think the SawStop would make people much more confident about being near the blade. Yes, on paper and in demonstrations it works a treat, but that would not give me enough trust in the device to go haphazardly placing my fingers near the blade. I'd treat it the same as any other saw.

This is probably exactly how it works, the man was just wetting his hands for added safety. I guess thats the safest way to stick your finger in a saw blade

@boyntonstu,
You can criticize it here all you want, but what are we supposed to do? You might want to find the original source of this ingenious device , but really, this thing is a technological marvel made by a very smart inventor and there's no denying it

Exactly. The same reason you won't see me flailing a loaded rifle in the direction of other people even though the safety's on. Intelligent operation of any device can preclude a large number of accidents.

i dont think it is to make people more confident near the blade its just for those people that are stupid/unlucky enough to get into that situation, it happens people loose fingers and hands on those things, it just stops that from happening

If you read my post i say ''moveing lawn mowers blade'' no mention of circular saw of any kind.
I sure can see anyone using a chansaw puting on some nylon pant if it can save a leg, ffs id where plate armor if i had to.
