The setscrew holding the pulley on the motor shaft came loose and the hole in the pulley is now too big. The hole is enlarged and the entire pulley wobbles when you turn on the drill press. I called the number on the central machinery owner's manual and I was told that the replacement part is not available. They told me the part is standard and I should be able to pick one up at a local hardware store. Well, I've tried and nobody I called has anything like it. Does anyone know where I can get the motor pulley for the drill press?
