I use a simple foot switch on my drill press.  it is just an 
electrical box with a wire on one side and a recpticle on the other.  
I think they call it a deep switch box.

anyway, a momentary pushbutton on it as the only contorl.

The cord pugs in to the wall, and the drill plugs into the 
recpticle.  the momentary makes contact as long as my foot is on the 
button.

When taping holes, I need a hand on the part and a hand on the 
spindle feed.  the foot switch allows me to control the motor.


I was thinking of using relays and a reversable motor, but then I got 
a taping head and that is all moot.
