Thanks for the suggestion, I have already considered this as I have used them on a small hobby Milling machine. My problem is, I already have the Stepper motors, so until I can prove to her indoors who must be obeyed, they will not work, she would divorce me for spending that kind of money. If I can confirm they will do the job I will need to spend on Ball screws and Ball Nuts but that should please her.

Again, thanks for the suggestion.
