Bill, if you reread the original post, you will note that he does not
propose running the DC motor on DC. Brush motors will run on AC, and he
might be able to use a router control, provided he matches the voltages with
a transformer. This could be tricky, though, because it depends on how the
transformer reacts to the peculiar waveform output of the speed control.
Putting the transformer ahead of the speed control could pose other problems
with the triac--I just don't know. And then again, it might work just fine.
