Just before I recently retired, I talked my boss into looking into a
SawStop .. .. .. he liked it and bought one for our shop. After
receiving it, he and the plant manager wanted to see a demonstration ..
.. .. after all, we did buy 5 extra cartridges. I got the opportunity
to perform the demo on two occasions, and it went perfectly both times.
We were using a blade ground with an ATB configuration. I pre-cut a
"v" notch in a piece of 2"X6" and taped the hotdog in place. The saw
was started and the test board was pushed into the saw at a rate one
would never consider practical. In a moment, there was a loud "bang"
and the blade disappeared. Inspection of the hot dog's damage revealed
that only one tooth had cut the skin .. .. that was determined by the
fact that there was only a slight cut on one side of the dog .. .. if
two teeth ever touched it, there would have been two defined cuts about
1/8" apart. One day, I'll own my own SawStop. For now, I'll try to
just be extra careful and hope for the best.
As to the wet-wood concerns .. .. .. IF the SawStop detects marginal
conductivity, it coasts to a stop and flashes a code informing you that
it "sees" a problem and that it could trigger an event if you proceed.
At that point, you can continue, quit, or put the device in "by-pass".
A triggered event WILL destroy the cartridge ($59.00) and will most
llikely damage two or three teeth on the blade .. .. .. if it's a cheap
blade, toss it .. .. if it's a premium blade, have the teeth replaced
and have the blade sharpened right away. Eithr way, it's better than a
trip to the E.R. AND the trauma & heartach of knowing you COULD have
been spared the experience if you weren't so cheap and/or didn't happen
to care for the way the inventor markets his device.
In time, when the technology becomes more prevalent, I believe you will
initially see lowered insurance rates for shops that invest in this
technology. Eventually, you will probably see huge premium increases
for those shops who resist it.
Perfect-or-not .. .. it's in the cards for the future and there's no
getting around THAT.
