The feed rate in the hot dog demo video looks pretty realistic to me.

Just one man's opinion.

I would like to see the effect of the hotdog being pushed
"several feet/sec" into the blade.
Do you think it would still only make a small nick in the dog?

Do the math. According to SawStop, the brake fires in less than 1
millisecond, and the blade comes to a complete stop in 5 milliseconds.

If you're feeding your hand into the blade at, say, 2 feet/sec -- which is a
damn fast feed rate -- in 5ms, it moves all of one eighth of an inch before
the blade comes to a complete stop. That's a lot more than a nick, obviously,
but it's nowhere near an amputation, either.

And that assumes that your hand is in continuous contact with the blade the
entire time -- which it won't be.

Watching the slow-motion video on their site showing Steve Gass's finger
touching the blade, it's obvious that the blade drops out of contact with the
finger long before it stops spinning. The blade begins to drop after
apparently only two or three teeth's worth of rotation. At 5000 rpm (as noted
in one video), with a 40-tooth blade, three teeth of rotation is less than
*one* millisecond. And in that length of time, moving your hand into the blade
at 2 fps, you move only 0.02". That *is* just a nick.

You can very easily move several feet in one second. If the proximity
sensor was set so as to keep you far enough away from the blade that you
couldn't get to it before it stops, you couldn't use the saw. Tablesaw
accidents are over, the damage is done, in milliseconds.

You know I think if you have to replace a $100 blade and a cartridge it may
serve better to prompt you to find out what you did wrong than if the blade
simply spins down.

Actually, it would make surprisingly little difference in the size of
the nick although there could be some. There is only so much work you
can do in 5ms. IOW, there is no residual 'wind-down' during which time
any further cutting can take place. When that blade is gone out of the
path, it is gone. The cutting path recedes backwards and downwards at
that speed, you'd have to catch the blade on the way down. SawStop's
effectiveness isn't so much in the stopping of the blade as it is in
the disappearing act.

You are only condisering the type accidents that you are warned about.
There are plenty of accidents that happen when the unexpected happens. Say
a bee comes in and lands on your hand closest to the blade..... Not likely
but I have had that happen. Stay with woodworking long enough and you will
come to realize that just being careful is not enough. If a knot explodes
and you jump. You never know.

As I mentioned here before, I worked part-time at Woodcraft for 3 years
and occasionally still do. We've sold a lot of SawStops. A student
inadvertently tested it in one of our classes - only needed a bandaid.
Several customers have also "tested" it.

A large local cabinet shop has over 20 of the saws. According to their
maintenance supervisor, he installs a new cartridge about every month.
Running a saw 8 hours a day gets boring, attention wanders, ...

So I'd contend it has been working quite well for a few years. I know we
sold some 3 years ago, but I'm not sure about 4. And the store hasn't
been open 5 years.

PS: And for those of you who remember my report about my bloody finger,
no I don't have a SawStop - not on a retirees budget. BTW, the finger is
almost healed but still tender.

Well, that's why I asked about that a few days ago. Imagine, if you

stopping the blade is the only way to keep someone safer. (If the blade

cut and then stuck, you could conceivably die. A regular saw might do

Obviously, both mechanisms are there for a reason, and perform different
vital functions in making the saw stop effective.

It uses a "proximity sensor". It's not 1 sec after you touch the

Yeah, think about what your are saying here. Unless your glove is made out
of a substance that will not cut a glove is not going to be pulled into a
spinning blade. Wood being harder to cut than a cloth material or leather
does not get pulled into the spinning blade, a glove will not either.

This was discussed several years ago and I decided to do the experiment and
sacrifice a leather/canvas glove. I pushed both the leather and cloth
sections of the glove into the spinning blade. The blade simply cut the
glove, actually left a kerf but did not in any way pull or change the
direction of the glove.

That said I still would not recommend using a glove around any shop
machinery. The glove could be pulled into a drill bit on a drill press or
pulled in to the work on a lathe to name a few. Around a TS the loose parts
could touch the blade and if you were not expecting that to happen you may
be startled and react with a movement towards the blade.

I had some sort of string in mind while typing the post, just added glove
as a source of the string. Chances are excellent that the glove or
string would be simply cut or snapped, but having both mechanisms ensures
safety if the unusual happens.

This was discussed several years ago and I decided to do the
experiment and sacrifice a leather/canvas glove. I pushed both the
leather and cloth sections of the glove into the spinning blade. The
blade simply cut the glove, actually left a kerf but did not in any

I remember that post. The glove pulled in to saw thing might be a
specific pair of gloves (like chain saw) under specific sawing
conditions. IOW, impossible to disprove.

That said I still would not recommend using a glove around any shop
machinery. The glove could be pulled into a drill bit on a drill
press or pulled in to the work on a lathe to name a few. Around a TS

I agree with that, definately. A glove usually reduces the "feel" of
something, so you don't get as early of warning that something's going
bad.

It'd be difficult data to collect, but I'm still wondering if the
disappearing blade would be effective enough to prevent most injuries.
Rather than damaging blade and having a one-time-use-only cartridge,
maybe a reloadable charge could be set and the cartridge reused.

Dunno how well that would work in practice. SawStop uses the energy contained
in the spinning blade (angular momentum) to provide the force that drops it
below the table. I have to think that any mechanism that simply drops the
blade, while allowing it to continue to spin, isn't going to react anywhere
nearly as quickly as SawStop's -- maybe not quickly enough to do any good.

Not saying it won't/can't work... just saying, mark me down as skeptical.

force that drops it below the table. I have to think that any
mechanism that simply drops the blade, while allowing it to continue
to spin, isn't going to react anywhere nearly as quickly as SawStop's
-- maybe not quickly enough to do any good.

Not saying it won't/can't work... just saying, mark me down as
skeptical.

This sounds like a job for an engineer! Just how fast does gun powder
react any way? The mechanism would detect the impact, the firing pin
would release (it arms when the saw is turned on), and pow the blade is
dropped in to the cartridge.

Naturally, the forces involved would be extreme. Probably about as much
as the saw stop generates now, but with the added requirement that the
cartridge must be reusable and blade safe.

Yeah, think about what your are saying here. Unless your glove is
made out of a substance that will not cut a glove is not going to be
pulled into a spinning blade. Wood being harder to cut than a cloth
material or leather does not get pulled into the spinning blade, a
glove will not either.

I had some sort of string in mind while typing the post, just added glove
as a source of the string. Chances are excellent that the glove or
string would be simply cut or snapped, but having both mechanisms ensures
safety if the unusual happens.


This was discussed several years ago and I decided to do the
experiment and sacrifice a leather/canvas glove. I pushed both the
leather and cloth sections of the glove into the spinning blade. The
blade simply cut the glove, actually left a kerf but did not in any
way pull or change the direction of the glove.

I remember that post. The glove pulled in to saw thing might be a
specific pair of gloves (like chain saw) under specific sawing
conditions. IOW, impossible to disprove.

LOL, well just so happens that I have been cut with a chainsaw also,,,,
through the same type pair of gloves. Still have the scar on the top of my
finger. About 30 years ago a freind and I were out in the woods cutting up
fire wood. Just finished cutting a log that I had been holding up for him
to cut, the saw was idling and I dropped the log and swung my hand up. My
finger grazed the end of the bar. I felt it and looked down at the glove
and saw a gash. Pulling the glove off indicated a cut in my finger about 1
inch long


That said I still would not recommend using a glove around any shop
machinery. The glove could be pulled into a drill bit on a drill
press or pulled in to the work on a lathe to name a few. Around a TS
the loose parts could touch the blade and if you were not expecting
that to happen you may be startled and react with a movement towards
the blade.

I agree with that, definately. A glove usually reduces the "feel" of
something, so you don't get as early of warning that something's going
bad.

Exactly!


It'd be difficult data to collect, but I'm still wondering if the
disappearing blade would be effective enough to prevent most injuries.
Rather than damaging blade and having a one-time-use-only cartridge,
maybe a reloadable charge could be set and the cartridge reused.

From experience I can tell you that replacing a premium quality blade and
cartridge is not a financial burden at all. Because there are few to no
false triggers except for a few isolated cases you can rest assured that if
the trigger is set off you have actually saved yourself thousands of dollars
and a lot if pain. Been there done that. When I first heard about this saw
about 10 years ago I was quick to inquire as to whether the saw would
trigger if the blade was still spinning after the saw was turned off. It
indeed does.
IMHO paying a couple hundred dollars to replace a cartridge and blade may
give you a bit more incentive to review what happened. If there is not some
kind of penalty you may become more careless on some one elses saw and pay
the bigger price.

Some care, some don't, and, like your meddlesome and impertinent
neighbor down the street, it pays to identify.

I don't know the poster, but allow me to point out that there are a
lot of Canadians who take an interest in US politics. For several
reasons. Least of which is that we have nothing on the political
horizon ourselves which would stir any kind of interest. If you take
away spineless, idiotic douchebags, there is nothing left for us to
dislike.
Add to that, the cable companies carry all the
ABCNBNCCNNESPNCNETPBSCSB stations and henceforth we're inundated
with information from south of the border. Include the news from the
Net...and many of us are probably more informed about what's going on
than your average American...at least those of us who have an
interest.
In my case, I have a lot of friends, family in the US and I'm 5
minutes away from the border so sometimes I go shopping there JUST so
I won't have to read the ****ing french labels on our consumer goods.

Rusty is further away from me than you are from Massachusetts.... on
many levels. G

Oh... and we got something you don't have:
