It's here, SawStop for the Band Saw

googled it...

serve it up... looks to be scrumptious...

Yeah, I did too...good on pizza, or in penne pasta with sauce and Italian bread or just a big bowl full fried in iron skillet just to toss back as a snack.

  • Wonder how that works?  Cutting meat, cutting finger, how does it know?

    I used Pico Pica Hot Sauce...is that what does it?  

  • Maybe there is a radio active concoction comes with the saw to drink before operating it.

Do you need a band saw to cut it?

Well, it's for sure you couldn't cut it with a SAW STOP.

electrical potential. 

The operator is wearing a cuff or something that puts an electrically conductive pad against his skin. This pad communicates to a circuit board on the Saw, When there is a connection made between the operator and the saw the Brake Triggers.   The Rubber Gloves won't allow the metal of the band saw to communicate with the operator so he can handle meat get the saw wet etc. Once his gloves become porous or cut by the blade,  the saw comes to a sudden stop because the electrical potential between the operator and the saw connect triggers the braking mechanism.  

 

Notice the blade is not destroyed by the process?

Gosh

  • Upon detecting contact with the operator wearing a sensor band under protective clothing, the moving blade stops in a fraction of a second.
  • Second sensing system detects operator gloves moving too quickly (as in a stumble or flicking motion) in front of the moving blade.

Makes a lot of sense now.  It is amazing how quick blood starts to flow when using a band saw.  Been there, done that, hated it.

Don't think I'm familiar with this...does it taste like chicken?:rolleyes:

More like Crow,

Nothing was said about damage to the saw stopping system and production line down time. Did I Miss it?

pico farads and capacitance. 

There is a circuit in the system very much like the circuit in one of those touch pad lamps that are becoming popular.  Touch a metal pas  and the lamp turns on or off.

There is a relay controlling the high power and a little low volt circuit  to power the relay

The  voltage across the  blade is in pico farads as it's part of the circuit to power the relay

Maybe it's 50 or 60 pico farads.

You body had a hundred or two hundred more pico farads in the skin. 

When you  touch the  metal of the blade  the pico farafds of the circuit jump up dramatically and that is what energizes the circuit

Just exactly like whan you turn a lamp on with a  capacitance touch switch

I'm with you Dan.  I thought the principle behind the SawStop was reading moisture.  If it read a higher moisture content the safety would kick up. 

I'm equally confused but SawStop saws work based off of electrical capacitance in the skin.
