I have a Pratt & Whitney Model B (circa 1975 I think).
It has round linear ball ways.
Repeatability is good but for the size of the machine and weight, can only take mousey cuts.
Because the spindle has only a cam-lock on an NT30 holder, it is a pain to make adapt new holders.
Good base for a CNC machine and adapted for servo Z on the quill including encoder. 30-6000 RPM fully variable. 3HP
Steppers and ball screws in X Y. 1 Ton. Add drivers and Mach3 to make a machine. about 500mm x 300mm Y
I used it manually for years, but never added the PC
Any offers? Not the right forum, but was on topic before I drifted.
