Re: Repairing saw blades

I wanted to add one more thing. In the case of my saw, if the main motor for the blade should happen to shut down the drive motor for the vise continues to run. Causing the rock to drive into and up onto the blade, not good. There should have been a secondary contact within the main drive motor that would kill all power to the saw in the case of a main motor overload. A very simple thing to do, but this system is not in use within my brand of saw. I am unsure if any other manufacturers use this type of setup. I believe it would certainly reduce the amount of damage to the blades. They do make motors with secondary contacts within them. Yes they are a bit more expensive but think about the savings on replacing blades. It would also involve running a 5 wire electrical cord instead of a 3 wire cord from the motor at the rear of the saw to the front control box. Just sharing my thoughts, Ward.
