Keith, I got rid of the two DB200 motors I had. Too noisy for me. Replaced them with DC scooter moters instead. Much more quiet and variable speed and reversing as well. --

For the lower speed power is fed via a diode, so giving the motor half the voltage, although that doesn't mean it runs at half the speed. Often the diode blows and low speed no longer works. It's not

That is true. The only alternative, then, is to make your own blocks. At that point you can size them any way you like, and make them long enough to fit the full length of your vise jaws, for ideal
