I have a Van Norman #12 milling machine that I use as a hobby for making
scale live steam engines. I would like to add CNC to this machine.
Has anyone done this? Were the original type screws/nuts used or were
zero-backlash ones installed?

Ron,
Was this not a horizontal / vertical mill? It has no quill if I remember
right. This would mean the knee has to be raised and lowered for the Z axis.
I would say on at least Z, you must replace the existing acme with a
ballscrew if not all axis because of the friction. Esp if you are running
steppers. Sure is easier to set up the software and the cut will have a
superior finish.
