Stop the blade in the material?

Is this standard practice? I'd never heard of stopping a power tool with the blade in the material before, and I'd always avoided doing it. ------------------------------------------------- It's what I was taught. Lew That was suggested in a recent issue of FWW, as it would yield a better cut (because the moving blade won't then contact the edge of the work on its way back out/up). So far, I have to remind myself to wait! : ) Bill It is easier to wait if the saw has electric brake when the trigger is released. Don't they all now? Even my HF SMCS has a blade brake (thought it was a requirement). I'm really surprised that table saws don't have them. |

It works on almost any motor. Try it! Be ready to burn out the switch
without a ballast resistor though. -- KKK "EXT" wrote in message eb.com... Chop/trim saws have universal motors (with brushes) and to have them stop fast or brake you short circuit the motor when the power is disconnected. I can recall decades ago modifying slot cars by installing a switch to short circuit the little motors. When a universal motor is spinning without power, it becomes a generator. When the universal motor/generator is short circuited it will cause the motor to almost immediately stop rotating. Table saws use different motors and cannot easily be made to brake. |

Probably. It was free, and I don't need a better one badly enough to dig out my wallet. -------------------------------------------- Until you have an accident. Lew |

One simply waits for the blade to stop. A lot of cuts have been made with saws that did not have a blade brake, with no cut off fingers. Sometimes after a feature gets implemented, the voices cry out that you'll die if you don't have that feature - even though history proves differently. That's being a bit alarmist. -- -Mike- |

My tablesaw doesn't have a blade break... does yours? Neither does my circ saw... it's convenient having it, but not necessary... Just remember you'll shoot your eye out. ;-) But I do want a saw stop... -- Jeff |
