If you're referring to turnouts where the point and frog rails are all soldered together, and pivot about a point between the two, you'd probably have an easier time of it by handlaying the whole shebang. I built one many years ago for an inaccessible spot on a past layout. It was powered by a Fulgurex switch motor, a beautiful, but expensive piece of machinery. I had never handlaid track before, but I followed a magazine article: I believe it was in RMC, and perhaps by Allen McClelland. I can try looking it up if this is what you're talking about. You can purchase ready-made frog/point sets, too.
