Which reminds me, I need to call SS and inquire into the details of
cutting wet wood. I have cut wet wood and the saw simply shut down
after cutting a few inches. It continued to do this until I used the
over ride switch. But I wonder what is going to happen if I cut into my
aluminum miter fence...
That is not a certainty but I would certainly return the blade to the
manufacturer with details and an estimate to restore. I understand that
some have been repaired.
I am not sure that realistically it will matter one way or another.
Considering the fact that you save a trip to the ER the cost of a new
blade and brake does not even factor in if you screw up.
For certain the Bosch will be less expensive for every owner to perform
the weenie test. ;~)
There are those that look at it that way but if you test the limits of
your anti lock brakes by driving more recklessly there is a big
possibility that you are going to do something else that is stupid which
will kill you. I don't buy it myself. I'm not one to look down the
barrel of a gun and pull the trigger because I know the safety is on....
LOL... I bet there are those that would not want that feature to save
their lives to keep from totaling the airplane..
For me absolutely the SawStop was worth the price. 3 table saws ago I
cut half my thumb off on my TS. No one could believe that happened to
ME. I was pretty strict safety.
Unfortunately I am not up on the 1,342,657,345,343,001 possible ways to
harm your self with a TS. I don't believe anyone else is either. Then
add to that no one is perfect and some times we work a little too
long... There are countless reasons. Anyway I can afford it so I
bought it. I really don't want to go to the ER again. FWIW I had
turned my saw off before cutting my thumb. Yes it was a dumb mistake
and one I repeated one year later. It all happened so fast I had no
idea what happened. Fortunately when I repeated the mistake 1 year
later I did not have as much thumb in harms way and only felt the breeze
of the blade as it was coasting down to a stop.
I would say for the vast majority no. For those that throw caution to
the wind, if this does not get them something else will.
And FWIW putting a blade brake on a saw does not guarantee not being harmed.
What happens to the blade?
is it pinched and warped or something more violent
Can't put a price on having all your original appendages
i didn't know how the SS worked other than I saw the gizmo at
the heart of it, the electronic part not the mechanical
well they gather mountains of data because that's what insurance
companies do and these were not daredevils just normal drivers
that thought hey I have ABS so i can expect more from this car
it's a subtle thing that showed up after a lot of data
we will never get that data with tablesaws
i think the most important thing is to understand what's really
going on with any tool
people need to stop and think what forces are involved
what might happen if something goes wrong
which direction will it go, etc.
it comes easier to some than to others
no joke there're definitely pilots that see it as an impediment to
honing and keeping real pilot skills
but it sells more planes, funny thing is those planes without a
chute are really nice and much safer than the previous designs
but it comes down to good maintanence with planes
sory to hear that
It's potential to harm is great but it's overblown and I think that
is even a problem for a lot of folks, they fear the table saw and
operating it in fear is not good combo
plus as I've seen you mention it's a well made saw
I'm glad you said that because the mindset in the shop or around
power tools is very important
gotta know when to do something with potential for harm
I do most cutting early when I'm fresh but may be a luxury for some
if I'm distracted with something try to deal with it then get back
to the saw
A spring loaded aluminum brake pad with relief holes drilled in it is
pushed up into the spinning blade. It normally rests less than 1/8" from
the blade and is about 2" long. The holes allow the blade to penetrate
deeply into the aluminum. Also the blade drops below the surface of the
saw releasing tension on belts so that the brake does not have to stop
the momentum of the motor too. Because most quality carbide blades can
very easily cut through aluminum I don't believe the damage is severe
but I certainly would want the manufacturer to do and sign off on the
repair. I suspect a few teeth would have to be replaced and the blade
maybe be re flattened. something I have Forrest check for every time I
send my blades in for resharpening.
Exactly and then expect the unexpected.
LOL yeah that same through process is mentioned with TS safety by some.
And that is a good thing but having a safer saw is part of practicing
Absolutely. You certainly should not feat operating a TS as this is the
first sign that you may not know all of the possible situations you can
encounter if you are not thinking about what you are doing. OTOH you
should feat what can happen if you are careless.
After I cut my thumb I was more fearful of the saw, up until I almost
cut my thumb again and finally realized exactly took place. Originally
I thought I was cutting a piece of wood and had a kick back. I was
cutting a dado. In actuality I had finished the cut, laid the wood
down, turned the saw off, and was reaching over the spinning blade to
grab the far end of the fence to remove it.
New rule.... don't go near the blade after a cut until you see it stop
spinning. Seems pretty damn reasonable to do this anyway but some of us
learn the hard way. But having said that there are numerous similar
ways to be hurt while not cutting wood.
The industrial version certainly is, there is a lot of cast iron under
the table. A comparison I make is that the SS industrial, being a
cabinet saw too, is that it has about 200 lbs more iron in the trunnion
assembly. It weighs in at about 700lbs with the hydraulic mobile base,
52" capacity fence and out feed rollers.
The SS Professional saw I am sure is every bit as well built as most any
cabinet saw in the same price range. I had a Jet cabinet saw and wanted
to step up to heavier and to a larger/deeper table top in addition to
having the safer features of a riving knife and the blade brake. That
was the only reason I chose the industrial over the professional version.
Yes, if you are on a deadline you have to often work past your prime
attention time. I try to never use the TS when some one comes up to
visit me in my garage unless they are actually there to help.

"If you don't hear the sound of a power tool, please don't pound on the doo

Ok, to be completely honest as to how this works the aluminum block is
not fired. It is under spring tension and held in place by a fusable
link. When the machine detects skin contact an electrical charge is
sent to melt the fusable link and the spring pushes the aluminum part of
the brake into the blade. The rotation of the blade does the rest, it
naturally cuts and jams into the block like it would into a piece of wood.
I have yet to see a blade destroy itself after this event, and I have
seen it happen many times in demonstrations. Certainly the blade is
damaged to some extent and may certainly not be worth repairing but is a
far cry from being non survivable or destroyed.
There are several pictures here of a blade that was used in the test. I
don't see anything wrong with the blade but I certainly would want it to
be checked out before returning it to normal use.
If you google sawstop blade brake and click on images there will be
numerous images of blades imedded in the brake and and after the brake
was removed. None that I can see is even missing a carbide tooth. But
again I would certainly want to have the blade checked out before reusing.
Now having said all of this the force of the motor is gone when the
blade drops and the brake trips so I am certain that this minimizes
damage to both the blade and brake.
And from the expert advice at the SawStop FAQ web site,
Can the blade be reused if the safety system brake is activated?
When the safety system activates, it will often damage one to two teeth
on the blade. It is usually cost-effective to have high-quality blades
repaired by a qualified blade sharpening service. However, less
expensive blades should be discarded.
wonder if this idea came from industry to if it's a novel idea/approach
damage is what
bent/warped blade or fractures or
Who would check it out to your satisfaction and what would they charge
I would just try the blade and see if it works
BTW in the bosch video I thought I saw the blade out of balance or
off center when it was restarted
maybe it was just the logo on the blade
