Hello everybody. New member, first post. I recently purchased a Model 500 for a great price. It runs smooth, has cutter, oiler and reamer. Threading die is missing, so I will be using hand dies with it. Since I will be using hand dies, I would like to add a foot switch for safety. Is there a foot switch available that the machine plugs into or will I have to rewire the power cord? Is there a manual available for this machine? I am sure it needs some grease or oil from time to time. Last question: What model threading dies fit this machine (just in case I come across a good used one).
