Nice....thanks for the link. My machine uses a completely electronic controlled orient and I am still trying to figure out how to make it work here. At some point if I cannot get it I may have to engineer some sort of mechanical setup but REALLY want to make it work as it came from the factory. Right now I am just making parts on it and getting parts here to do my turning center... Congrats on a job well done. Peace
