Me and a friend of mine built a speed control to the schematic sent in from Cane Pole. Many thanks my friend for the help. My friend is an aeronautics engineer so most of the work was done by him. Actually most of the work was done by Cane Pole. Any who the thing works. I now have variable speed at 5 diffrent settings. You were right Cane Pole this was not for beginners. We have about $35.00 invested, if I had bought a maximizer could have been $300.00 or more.
