Unbelievable Table Saw.

That guy has conviction in his product, he also still has the fingers.

Sorry lads, but it's BS.

 

When you think about it, how could you have a sensor in every tooth of a blade?

 

Clever film though.

 

Reminds me of the stuff they had on 'Tomorrows World'.

 

Showing my age a bit there....

 

I think it would be the whole disk not just individual teeth. If I understand it correctly your finger being conductive just completes the circuit and trips the safety device.

Come on!

[How many revs per second times how many teeth per rev] well that's the ..th of a second before the next tooth comes down and in which that signal has to get to a cpu and the stop mechanism spring in.

And where are these sensors and why don't they interfere with the cutting and why don't they get worn away by the cutting.

And just what is this 'circuit' that gets 'completed'.

Nice try:001_tt2:

Happy to be wrong:001_smile:

 

ETA Not even the next tooth - the first tooth doesn't go through does it? We're talking instantaneous action: not possible.

What does this have to do with the original post ( other than its a table saw ) ? I know which one I would want !

 

Seems like an ad bot.

Saw one working a while back but only works with small blades. SawStop | America's #1 table saw | SawStop.com | SawStop

Something simple like an ignition unit on a chainsaw creates a spark approximately 14,000 times per minute, air bags inflate before your face hits a steering wheel, why is this so unlikely?

 

Have a look at their website, the videos will explain it all for you.

It is plausible, and after all the stop IS instant, at the cost of the blade and aluminium stopper.

But, bear in mind a "cut" , even a deep or bad cut is WAY preferable to chopping a finger off.

The sausage test was pretty clear, it did get "nicked" before the blade stopped.

However the real finger test was not realistic, in that he very very very slowly edged his finger up to the spinning blade, therefore it did NOT even get nicked.

But yes, only suitable for dry joinery timber, an for God's sake DONT sneeze!

Thats exactly how I saw it ( pardon the pun ) If you rammed your finger in at speed it would get cut/nicked but most of it would still be attached . After all the finger needs to make contact with the blade to establish the conductive circuit .

Big cojones! anything is better than the trauma caused by a circular saw when fingers and hands go in......seen it a few times over the years including my own thumb.

 

But like someone said, how would it react on a larger blade - even if it is slower?
