Per the video you just supplied, the cost of the wrecked
blade and the SawStop module is $60. And it looks like
a device that could be sold for around that amount. So, I would
not buy a crawling helmet. But your cheap shots at
SawStop and me appear unwarranted. Or are you so
cheap and dumb that you think $60 for such a safety device
isn't worth it?

No reason it can't be adapted to those things. It's basicly
a touch sensor that reacts to increased capacitance
from a person coming in contact with it. That triggers
a spring loaded ram that jambs into whatever is spinning.

And you've hit on the beauty of the system. UInlike many of
the safety features on products today, this one is not
intrusive. I just bought a Poulan electric chainsaw. And while
I'm happy with and think it's a great buy for the money, it
does have two safety features that are a pain. One is the
button that you have to push before you can pull the trigger.
With gloves on, it's hard to do it. The other is it has a hair
trigger that you have to not only keep fully depressed but
a LOT of pressure on to keep the saw going. If you just
let off the pressure a bit, the saw begins to stop.

The problem with SawStop has been that each false alarm requires
replacing various mechanical components, which takes time and money. It
doesn't make too many false alarms to make guards more economical.

My recollection is that the sensor measures resistance (not capacitance)
between saw blade and ground, so it won't work with wet wood or metal
stock. The patents should tell the tale.

Do you have any figures that indicate that "false alarms" are an
issue?

I agree that "each false alarm requires replacing various mechanical
components" but if there aren't any false alarms, then it's a moot
point.

My only point being that using the words "each false alarm" might make
the reader think that they happen often enough to negate the value of
the device. That is not something I have read or heard about the Saw
Stop device, but the info might be out there somewhere.

False trips have never been proven to be of any fault of the saw. I
have read about the SawStop having an issue with an older electonic
digital watch but Sawstop isolated the problem and took care of the expense.

That said if you are having false trips it may very well be likely that
you are doing something wrong and probably the perfect candidate for a
SawStop, you are probably going to benefit from it. I know of no one
and have read of no one that has actually purchased a Sawstop having
this problem with out a reasonable solution. Users are not complaining.


The only people complaining about the perceived SawStop problems are
those that are uneducated on the product.

AFAIK there's no data available from SawStop on the number of false
positives (and, of course there's no data on how many users turn the
bypass control on to be sure to avoid any chance of same when working
with wet wood such as PT).

The best one can tell from the patent is

"In many of the exemplary embodiments and implementations described above
and in the references incorporated herein, detection subsystem 22 relies
on the inherent electrical capacitance and/or resistance of the user's
body to modify the effective capacitance and/or resistance of the
cutting tool or operative structure."

The patent is (as are all well-constructed ones) written to cover not
only the actual "embodiment" but every possible variation of it that the
applicant can manage to stretch the colorful language to cover. In
early interviews it was pretty clear that it is capacitive coupling that
was used at least in the initial product and I presume it is likely
still the same fundamental technology used in the current saws w/ some
improvements owing to the experience factor. It's the same idea as the
"touch switches" on table lamps, etc. -- the body has much higher
capacitance owing to the water content than does dry lumber and if the
blade monitor sees a drop it presumes that's not good and fires.

It's a clever technology and worthwhile--my complaint w/ Gass is his
attempt to now force it on the market to make a bundle by
legislative/mandatory means rather than by winning the competitive
battle in the marketplace.

SawStop and me appear unwarranted. Or are you so
cheap and dumb that you think $60 for such a safety device
isn't worth it?
================================================== =====

Still more economic fabrication??

The replacement "crumple" thingy *alone* is $69, according to Amazon.
The *whole system* takes a $499 Crapsman table saw, and zooms it up to pert
near $2,000.

Plus, if you notice, those tests were conducted at a *very slow* entry
speed.
If Moi were feeding wood into a table saw at that speed with my finger in
the blade path, I'll bet dollars to donuts I'd jerk dat finger back way
before the blade even came near the bone, proly not much more than a bandaid
could handle.
But poss. a nasty cut too, but nowhere near losing a digit. Of course, much
diff. story in a RAS.

Otoh, in the original video in this idiot/table saw thread, had HIS hand
actually collided with the blade at that hand speed, I wonder how effective
this device would be. SOME damage control, proly, but how much? Mebbe not
enough.
Well, let them demo this sawstop ditty while *whipping* a hot dog into the
blade, see how the hot dog fares. Any such vids?? Not from the mfr, I'll
bet.

If I'm wrong, I bet wrong then. We'll see.

And ahm all for safety, I just detect the looming of the inevitable economic
sodomy.
And, once again the "ante of complexity" just skyrockets in the name of
"safety", again toward economic sodomy.
2012 cars are 50% heavier than cars in 1975 (a 2000# beetle then now weighs
3000#), and pretty soon you'll need a certified dealer to fix a flat for
you.

But then, economic sodomy dudn't seem to faze you, given your support of
Romney the Job Eviscerator.
http://www.villagevoice.com/2012-04-...ican-parasite/

OK, time for an Honesty Session:
Any of you Safety Assholes purchased a crawling helmet for a toddler??
If not, WOULD you???

That said if you are having false trips it may very well be likely that
you are doing something wrong and probably the perfect candidate for a
SawStop, you are probably going to benefit from it. I know of no one and
have read of no one that has actually purchased a Sawstop having this
problem with out a reasonable solution. Users are not complaining.

Well, http://en.wikipedia.org/wiki/SawStop mentions the problem. Google
sawstop false trips for quite a few hits. Overall, it seems pretty good,
but not perfect. And crunching a good blade could cost *much* more than the
sawstop replacement crumple thingy.

The problem with SawStop has been that each false alarm requires

My recollection is that the sensor measures resistance (not capacitance)
between saw blade and ground, so it won't work with wet wood or metal
stock. The patents should tell the tale.

AFAIK there's no data available from SawStop on the number of false
positives (and, of course there's no data on how many users turn the
bypass control on to be sure to avoid any chance of same when working with
wet wood such as PT).

The best one can tell from the patent is

"In many of the exemplary embodiments and implementations described above
and in the references incorporated herein, detection subsystem 22 relies
on the inherent electrical capacitance and/or resistance of the user's
body to modify the effective capacitance and/or resistance of the
cutting tool or operative structure."

The patent is (as are all well-constructed ones) written to cover not only
the actual "embodiment" but every possible variation of it that the
applicant can manage to stretch the colorful language to cover. In early
interviews it was pretty clear that it is capacitive coupling that was
used at least in the initial product and I presume it is likely still the
same fundamental technology used in the current saws w/ some improvements
owing to the experience factor. It's the same idea as the "touch
switches" on table lamps, etc. -- the body has much higher capacitance
owing to the water content than does dry lumber and if the blade monitor
sees a drop it presumes that's not good and fires.

It's a clever technology and worthwhile--my complaint w/ Gass is his
attempt to now force it on the market to make a bundle by
legislative/mandatory means rather than by winning the competitive battle
in the marketplace.

Well stated.
I myself prefer "economic sodomy", but nothing wrong with pretty-ing it up a

Per the video you just supplied, the cost of the wrecked
blade and the SawStop module is $60. And it looks like
a device that could be sold for around that amount. So, I would
not buy a crawling helmet. But your cheap shots at
SawStop and me appear unwarranted. Or are you so
cheap and dumb that you think $60 for such a safety device
isn't worth it?
================================================== =====

Still more economic fabrication??

The replacement "crumple" thingy *alone* is $69, according to Amazon.
The *whole system* takes a $499 Crapsman table saw, and zooms it up to
pert near $2,000.

Plus, if you notice, those tests were conducted at a *very slow* entry
speed.
If Moi were feeding wood into a table saw at that speed with my finger in
the blade path, I'll bet dollars to donuts I'd jerk dat finger back way
before the blade even came near the bone, proly not much more than a
bandaid could handle.
But poss. a nasty cut too, but nowhere near losing a digit. Of course,
much diff. story in a RAS.

Otoh, in the original video in this idiot/table saw thread, had HIS hand
actually collided with the blade at that hand speed, I wonder how
effective this device would be. SOME damage control, proly, but how much?
Mebbe not enough.
Well, let them demo this sawstop ditty while *whipping* a hot dog into the
blade, see how the hot dog fares. Any such vids?? Not from the mfr, I'll
bet.

If I'm wrong, I bet wrong then. We'll see.

And ahm all for safety, I just detect the looming of the inevitable
economic sodomy.
And, once again the "ante of complexity" just skyrockets in the name of
"safety", again toward economic sodomy.
2012 cars are 50% heavier than cars in 1975 (a 2000# beetle then now
weighs 3000#), and pretty soon you'll need a certified dealer to fix a
flat for you.

I may have mis-spoke.
I just read somewhere that the sawstop adds "only" $100-200 to the cost of
a saw.
BUT, saws sold by sawstop push $2,000.... intrinsically much better saws??
I doubt it, but it's poss.

I would like to see a $500 Crapsman table saw with and without the sawstop,
see what the difference is.
In the meantime, I posted this non-destructive solution in another reply:

isn't any such thing as the Sawstop cartridge mechanism must be designed

That's what I thought and that's why I asked.

However, something you said needs some clarification, at least to me.

You said: "That said if you are having false trips it may very well
be likely that you are doing something wrong and probably the perfect
candidate for a SawStop, you are probably going to benefit from it."

What could a user be doing that would cause "false trips"? If there
are no documented false trip issues, then wouldn't any trips caused by
someone doing something wrong actually be *real*?

Theoretically, one could get close enough to the blade to trigger it w/o
actually touching it. That scenario is mentioned in the patent
background since the detection circuit is capacitively coupled there
doesn't have to be actual contact if the disturbance of the capacitance
field is sufficient the actuator logic will think "something's bad" and
trigger.

At least initially there was a manual override switch that one could use
to disable the detection circuitry and I presume there still is altho I
haven't searched the current sales lit thoroughly. It was (is) there
for the express purpose of preventing a false positive trip if the saw
were being used for, say, wet PT lumber or some other product that had a
high-enough capacitance to cause actuation. If the operator thinks it
isn't needed for a given cut or forgets to flip the switch, that's a
second category (albeit one could claim that one is operator error only,
not a false positive, still, the effect is the same).

Similar to that is the possibility of an embedded metallic object (a
nail, iow) that happens to also be in contact w/ the table at the time
it's hit by the blade--that will almost certainly trigger it even though
SS says just a nail if not grounded likely won't be large enough to.

There is always then the chance failure--stuff happens; no technology is
perfect. Undoubtedly small, but still has to be finite and positive.

I notice now that SS has a submittal form for "saves" that says if you
ship them the cartridge/blade and they can determine it actually was
flesh that caused the trip they'll provide a replacement cartridge.
That doesn't cover the cost of either repairing an expensive blade or
replacing one, but it is something. Of course, in that case the avoided
cost of the medical bills likely otherwise probably overshadow the
repair costs significantly.

There is no information at all on the SS site on actual statistics of
any value to do any estimation at all of either type of
actuation--needed or false. There _is_ a (to me) blatant use of the
scare stories and a big countdown clock of "time to next saw accident"
that's just tacky, but then that's me...

Gullet should be at the surface cut or just tad proud for
crosscutting/ripping, granted.

As for "never", well, every rule has its exception. If I'm cutting for
a notch, I may well set the blade at its maximum height to have the
least angle possible and thereby the shortest possible undercut on the
back side of the piece...

But, in general, the point is good one...excessive blade exposure is to
be avoided.

doesn't make too many false alarms to make guards more economical.

My recollection is that the sensor measures resistance (not capacitance)
between saw blade and ground, so it won't work with wet wood or metal
stock. The patents should tell the tale.

Do you have any figures that indicate that "false alarms" are an
issue?

I agree that "each false alarm requires replacing various mechanical
components" but if there aren't any false alarms, then it's a moot
point.

My only point being that using the words "each false alarm" might make
the reader think that they happen often enough to negate the value of
the device. That is not something I have read or heard about the Saw
Stop device, but the info might be out there somewhere.

False trips have never been proven to be of any fault of the saw. I
have read about the SawStop having an issue with an older electonic
digital watch but Sawstop isolated the problem and took care of the
expense.

That said if you are having false trips it may very well be likely that
you are doing something wrong and probably the perfect candidate for a

The problem with SawStop has been that each false alarm requires
replacing various mechanical components, which takes time and money. It
doesn't make too many false alarms to make guards more economical.

My recollection is that the sensor measures resistance (not capacitance)
between saw blade and ground, so it won't work with wet wood or metal
stock. The patents should tell the tale.

Do you have any figures that indicate that "false alarms" are an
issue?

I agree that "each false alarm requires replacing various mechanical
components" but if there aren't any false alarms, then it's a moot
point.

My only point being that using the words "each false alarm" might make
the reader think that they happen often enough to negate the value of
the device. That is not something I have read or heard about the Saw
Stop device, but the info might be out there somewhere.

False trips have never been proven to be of any fault of the saw. I have
read about the SawStop having an issue with an older electonic digital
watch but Sawstop isolated the problem and took care of the expense.

That said if you are having false trips it may very well be likely that
you are doing something wrong and probably the perfect candidate for a
SawStop, you are probably going to benefit from it. I know of no one and
have read of no one that has actually purchased a Sawstop having this
problem with out a reasonable solution. Users are not complaining.


The only people complaining about the perceived SawStop problems are those
that are uneducated on the product.


Well, http://en.wikipedia.org/wiki/SawStop mentions the problem. Google
sawstop false trips for quite a few hits. Overall, it seems pretty good,
but not perfect. And crunching a good blade could cost *much* more than the
sawstop replacement crumple thingy.

http://www.thewoodwhisperer.com/arti...awstop-killer/ has a nice
alternative, non-destructive.


I'll take the saw stop over that add on shield.
First that shield won't work when using my tenoning jig.
Second I can't clearly see what I am doing and consider it an
obstruction, I don't use a guard for that reason.

However, something you said needs some clarification, at least to me.

You said: "That said if you are having false trips it may very well
be likely that you are doing something wrong and probably the perfect
candidate for a SawStop, you are probably going to benefit from it."

What could a user be doing that would cause "false trips"? If there
are no documented false trip issues, then wouldn't any trips caused by
someone doing something wrong actually be *real*?


Cutting wet wood and not over riding the system. Just for starters.
No fault of the saw. I see a false trip as something that should not
have happened and is the fault of the saw.

If the saw was running, it will stop if there is a loss of power. Yes

Per the video you just supplied, the cost of the wrecked
blade and the SawStop module is $60. And it looks like
a device that could be sold for around that amount. So, I would
not buy a crawling helmet. But your cheap shots at
SawStop and me appear unwarranted. Or are you so
cheap and dumb that you think $60 for such a safety device
isn't worth it?
================================================== =====

Still more economic fabrication??

The replacement "crumple" thingy *alone* is $69, according to Amazon.
The *whole system* takes a $499 Crapsman table saw, and zooms it up to
pert near $2,000.

Plus, if you notice, those tests were conducted at a *very slow* entry
speed.
If Moi were feeding wood into a table saw at that speed with my finger in
the blade path, I'll bet dollars to donuts I'd jerk dat finger back way
before the blade even came near the bone, proly not much more than a
bandaid could handle.
But poss. a nasty cut too, but nowhere near losing a digit. Of course,
much diff. story in a RAS.

Otoh, in the original video in this idiot/table saw thread, had HIS hand
actually collided with the blade at that hand speed, I wonder how
effective this device would be. SOME damage control, proly, but how much?
Mebbe not enough.
Well, let them demo this sawstop ditty while *whipping* a hot dog into the
blade, see how the hot dog fares. Any such vids?? Not from the mfr, I'll
bet.

If I'm wrong, I bet wrong then. We'll see.

And ahm all for safety, I just detect the looming of the inevitable
economic sodomy.
And, once again the "ante of complexity" just skyrockets in the name of
"safety", again toward economic sodomy.
2012 cars are 50% heavier than cars in 1975 (a 2000# beetle then now
weighs 3000#), and pretty soon you'll need a certified dealer to fix a
flat for you.

I may have mis-spoke.
I just read somewhere that the sawstop adds "only" $100-200 to the cost of
a saw.

That is the number that has and or was quoted 10 years ago in 10 years
ago dollars. But on the other hand you need to understand the
difference in the cost of adding the feature to a saw and what the
retail price will be. You are no going to buy a new saw for cost.



BUT, saws sold by sawstop push $2,000.... intrinsically much better saws??
I doubt it, but it's poss.

You are really adding nothing of value, you are obviously not familiar
with this product which BTY is not new by any stretch of the imagination.




I would like to see a $500 Crapsman table saw with and without the sawstop,
see what the difference is.
In the meantime, I posted this non-destructive solution in another reply:
http://www.thewoodwhisperer.com/arti...awstop-killer/
We'll see who wins.

So, who's buyin crawling helmets out there?? LOL


So have you heard of the the iPad, it is much newer than the SawStop.

Actually, I have seen a demo of Gass w/ a hotdot on a stick and swinging
it pretty quickly. It didn't get more than a nick that at most a stitch
or two would take care of.

As for the VW, sure--it was nothing but a tin can on wheels then...otoh,
a
1975 Buick weighed probably 25% more than the largest one you could
manage
to equip today and that's pretty much true on the overall US fleet
average. Has had to happen because of the EPA fleet-average mileage
rules...

The cost differential on the SawStop is owing imo to brand
identification
and uniqueness in the field as well as to the actual production cost
differential between that saw and the same one w/o the actuator
mechanism--that really is a meaningless comparison as there isn't any
such
thing as the Sawstop cartridge mechanism must be designed into the saw
from the git-go--it can't be retrofitted into a conventionally
designed/built saw.

Actually, that was my initial understanding, until I read the thing about
SS
adding only $100-200 to a saw, giving the impression it could be
retrofitted
somehow.

What on earth about it costing $100 to $200 to add
it to a saw gave you the impression in can be retrofitted?
When they said that air bags or anti-lock brakes would
add $300 to a car, did you think that meant you could
retrofit it to your 1965 Chevy?
Did you look at the same video we all did? It also relies on sensor
technology that detects
the change in capacitance/resistance when you touch
it. For that to work, clearly the blade has to be perfectly
insulated from the table and the rest of the apparatus.
Think that's possible with your current saw? Actually, I bet the
resistance is near zero.
Steel blade, shaft, bearings, etc.



So there really IS economic sodomy here....
Trader4 ought to be ecstatic.....

Depending on the way it's set up, it might be possible to leave the
detection system active even in the case of a power failure. As long as
there was enough energy to actuate the cartridge release, the system
could still function.

I doubt it, but it's poss.

You are really adding nothing of value, you are obviously not familiar
with this product which BTY is not new by any stretch of the imagination.




I would like to see a $500 Crapsman table saw with and without the
sawstop,
see what the difference is.
In the meantime, I posted this non-destructive solution in another reply:

We'll see who wins.

So, who's buyin crawling helmets out there?? LOL


So have you heard of the the iPad, it is much newer than the SawStop.

Whatever you do, don't quit your day job -- heh, which proly doesn't pay
much, otherwise you proly wouldn't be such a snippy li'l prick.

No reason it can't be adapted to those things. It's basicly
a touch sensor that reacts to increased capacitance

Capacitance, eh? Then like an iPad, it won't work if you wear gloves?


No, problem...just slice thru the glove first...

23. What if I am wearing gloves when cutting? Will the safety system
still work?
Yes. The blade must first cut through the glove and contact skin
before the safety system will activate.
