Re: STG and Parallel Port

Hi Erie
I wish I had an inverter that put out a signal.

I am using a Porter Cable 7518 3.25 hp router motor!
Actually it might have a tach in it somewhere
for use with the phase type speed control/
soft start. But I doubt it... it probably uses
ir comp. In any event it is easier to just put
a little coil near the collet nut. The whole thing
will cost about $5 for parts... and $1000 for labor! :^)
