Mastercam X4 machine Def file for converted lathe

Hi Guys,
I looking for a little help.
I have converted a small 11x29 lathe to CNC. It has a QCTP on the front.
I am using Mach 3 for the controller.
I am looking for a Machine definition file for Mastercam X4 that would match up to my lathe.
I also need to know which post-processor to select that matches up to Mach 3's capabilities.
Any help in pointing me in the right direction would be appreciated.
Thanks
Dirk
