Sorry Lee , Robin and Irvin
You started this thread and the mill that I am making is not CNC at least at the moment. I have no access to machining capabilty except an old lathe which drastically needs new bearings. As I have allready said I considered the Westberry vertical mill design but here were several reports of chattering on the sliding column. Here is a better pic of my design inspired by the Stepperhead, Gingery, Multimachine designes.
