Wow..that is a long post. I would advise against the foot switch for the table saw, though!! I like both feet on the ground when running the table saw and like concentration on the cutting area at all times on that machine!! Trying to keep a foot on a  switch could interfere with the needed concentration. A drill press  or Fordom on a foot switch make  sense.
