Thanks guys. I have completed the X axis cnc conversion. Using both brass and aluminium. I am using brass for the coupling and rod support for the stepper and aluminium for the plate screwed onto the X axis X2 table end plate.

Tested with mach3 and its working fine. Now onto Y axis. I will put up photos when I am able to. At the moment in my machine shop trying to configure mach3 to run properly with the stock lead screw.
