I am so impressed by the video offering at the moment. That is the serious remark.
Now, why does it work, is it sensing sausage, weiner or just any floppy bits having no resistance? Can it be overridden without using the disable function and is there some reliance upon the item being offered having electrical conductivity? Or more plausibly, might it afford protection to the original purchaser only, rather like a non-transferable guarantee, which would be at the cutting edge of marketing ploys!
Thank goodness this device has yet to reach bandsaw blades otherwise our frozen food would never get eaten, or there would be a lot of waste.

The specifics on how it works and such are discussed in detail at the SawStop web site. By the way, there is a specific exemption for bangers and mash--the sensing technology is not guaranteed to work in that application.

Thank you for that bit of common sense, I should have looked there in the first place. I am surprised we have so much in common with the humble sausage, perhaps we came from an original ancestor.
Now I have to find out if a dead mouse has the same effect as a live mouse. I could ask my wife to help with the experiment but have got used to her and do not want the trouble of breaking a replacement in to my adorable little ways. Also I would not know if alcohol concentrations interfere with the action.
After the contractor saw is released (2009), the next tool to be marketed is a bandsaw.
Infamy, they have got it in for me!
Mufti,
Bet all the sawblade manufacturers are lickin their chops! Next will be handplanes, spokeshaves, chisels and .........
How 'bout a mallet that stops B4 you hit yourself!?

No Bob, they use chops for hand saws, not the roundy ones. And what you lick in the privacy of your workshop beggers belief.
We have a democratic right to bash ourselves (and cut bits off) so this is an infringement of our lobotomies
Moof,
Bob may raise one corner of his top lip when I tell you this, but I am in the process of inventing a Special plane blade metal that uses nano-technology to sense when a user picks it up. It then reconfigures itself, depending on the grip the user employs.
For example, when it is upside down the blade edge goes dull, so the user cannot nick himself. When it is down and senses the presence of wood, it reconfigures itself to have that 1 micron edge that we all strive for with our diamond, oilstone and such.
The next stage is to make a whole plane from this Magic Metal, so that the user merely has to think what he would like planed and the new-fangled thang leaps from it's cupboard, puts the wood into a vise and planes it to perfection. I am thinking of calling it "robot metal".
I would ask Pedro for some help but he would probably steal my brilliant ideas just to make enough money to buy the old-fashioned, crude handtools that you have to operate yourself! At least one part of his brain has got neanderthal syndrome - that infection of the synapses that causes grown men and even a woman to mess about with multi-planes, axes, froes and the like. (My case is under control, of course it is).

Sir Froe,
I'm with you up to The next stage.
If you carry this ambitious and clever idea to The next stage then how in the world are you to make those fine pieces of yourn? Perhaps your intent is to render the Chinese ambitions moot?
Might I suggest that you begin marketing your idea to American furniture manufacturers who are sadly missing the boat? They seem to think that they must compete with the cardboard syndicate and lower the quality of their products in order to survive.
I truly believe that your fortunes (not necessarily of a monetary nature) are best assured by making pieces that reflect your talents as opposed to sucumbing to the throw away societal mentallity we are experiencing (spit).

Latake.. FUNNY!
I for one love your post!
You mean I don't have to buckle up my safety belt when using my #7 Clifton? (I removed the riving knife from it, but don't tell anybody.)
If Lataxe is determined to automate hand planin then methinks he needs to add some sort of dust collection and perhaps a catchy name, yes? I doubt if he can convince Adam C. to build a supply of plastic totes and knobs to go with it.
Mebbe he could call it the Froetool!

Bob,
You enquire: "If you carry this ambitious and clever idea to The next stage then how in the world are you to make those fine pieces of yourn"?
Well, I will just have to think of the piece and my Magic Metal tools will leap into action, so that when the chips and dust clear, there will be a gleaming toad on four legs or even one o' them queer Queen Annie jobs. I am saving the technique for my 90s, when I will be too weak to do anything except think. Also, the nanobots will be $5 for a thousand by then. Just imagine the pieces one might create just by thinking! I will try to keep my thoughts pure and clean (no I won't).
As to collecting plane shavings via an automatic attachment - I have been trying to commission that Philip for some time now to make one. All those bluddy shavings stick turnnnaciously to the boot-bottom, until one walks into the house whereupon they distribute themselves into all the places where they catch the ladywife's critical eye and I must get the hoover out again.
Lataxe, fangle-lover (especially shiny ones with whirring gears and switches).
someone may have posted this, but it works by sending an electrical signal through the blade, and when it is disrupted by either high moisture (ie a finger, weener or wet wood) or other metal, it trips the mechanism. It can be over ridden via a key, whish you should only use when cutting metal or really wet wood, or if you prefer to prepare your meat products on a tablesaw ;)

electrical conductivity I would assume.. I have no idea because I never looked up the patents..
What I post here IS NOT KNOCKING the SAW!..
I am sure the designers did their HOMEWORK AND THEN SOME.. AND THEN SOME MORE WORK!
Electronics and Mechanics working together! I have worked all my life with both.. Hell, I even started out with vacuum tubes as far as electronics!
They both fail! Why I earned a living most of my life making SERVICE CALLS!
Again... I AM NOT KNOCKING the product!
I just wonder if it makes the saw user feel so safe they cannot cut a finger or more off?
Just my thoughts...
Fair comments, I am of the opinion that non fatal road accidents would be drastically reduced if a spike protuded from the centre of the steering wheel. This would greatly reduce the costs of health care in the community and have spin offs in less ambulance and police involvement thus opening the way for tax breaks. Politicians and service engineers would be exempt!
No government ought in such cases to miss the chance of imposing a "get out tax" upon the estate of the deceased to make up for the taxes he otherwise would have paid had he not died. Note the "he", ladies in the circumstances would insist the man drove.
I hear you....
Just a comment I made.. As this old man thinks 'if you feel safe You are probably not safe as you seem!'
No, I agree entirely with your sentiments. Sometimes my humour, or attemps at humour, are not perhaps in tune with your side of the puddle. The trouble is I am rarely serious!
What about the poor saw!
3500-0 in nothing flat can't be good.
That is true, but I suppose the triggering of the safety shut down is a very rare event and thus acceptable.
Obviously saving a finger is more important, but I hate to think
of my saw ruined.
H,
When I was a racing cyclist we had a saying: "If you're about to fall off, make sure you thrust your nice soft body between the expensive bicycle and the nasty hard gravel or concrete. Bodies heal for nowt but Campagnolo and Columbus costs loads".
Sadly, this is not really applicable to finger loss vs a sawblade with one or two teeth mangled. Gravel-rash is character forming whereas finger loss prevents all sorts of desirable digital dexterity, at the time of loss and forever more.
Lataxe scar-arse; but digitally whole.
This poses an interesting question-
What if you had a Campy table saw ?
Isn't that a Felder:)Troy
"They both fail!"
That's true. That's why the computer inside the SawStop performs a diagnostic self-check every time it's powered up. Safety systems aren't designed and built the same way as "ordinary" electronic and mechanical equipment. There are multiple levels of redundancy, there are known chain-of-events paths for all of the "what if" scenarios, etc.
-Steve
To add to this, in aviation (where I have earned a living for the last 3+ decades) electronics are critical. And they are designed with various failure scenarios. Fail safe and fail operational are two of them.I suspect that if the electronics fail on the saw, it will shut it down and, to resume operations, one would have to manually bypass the mechanism. But I could be wrong..I don't own one. Yet.Cheers,Peter
Better life through Zoodles and poutine...
All the while trying to avoid that sometimes elusive single point of failure. Electro mechanical devices are subject to failure usually without any announcement ahead of time. :>)
By the way man, have you folks dried out yet!?
Regards,Bob @ Kidderville Acres

That's the whole concept of "failsafe"--designing something so that if anything fails, it does so in a way that won't compromise the overall safety. The great majority of safety systems are now pretty good in that regard--they require at least two (and frequently three or more) completely independent failures for safety to be lost.
We're 200 ft above the river, so the 4" of rain that we got just went down the hill and flooded the valley. I think the Hocking River is still above flood stage, but overall it doesn't seem as bad as we had two years ago.

Steve,
Are you close to or over 100 years old?
Every post I read that you've posted is one from which I learn something. You seem to have a broad knowledge base about a lot of different things. This, I think, must come from extensive experience - and that experience, naturally, must come from age...
Or maybe you're just bloviating and I'm too thick to know the difference.
Anyway, until you actually do get too old to post, well...keep posting..

Not that close to 100, but closer to 100 than to 0 (though not yet by very much).
