Z is very easy, you can easily fit a servo or stepper motor anywhere convenient at either end of the bed. You probably want to replace the entire apron. The ideal retrofit candidate would be a lathe with a smashed or missing apron. I confess I am not sure I would have the heart to retrofit a good, working, lathe. X is more tricky, there tends to be limited space for the nut, and mounting the motor is not that easy either. A readily-available backlash-free right-angled drive would be a huge help. I have spent some time considering ways to twist a toothed belt drive. The solution I came up with for my nasty lathe is here starting at post 15 http://www.cnczone.com/forums/mini_lathe/63621-mini_lathe_cross_slide_ballscrew_solutions-2.html > Are ball screws easy to find? Say, I have a 14x48" lathe. Yes, you can buy them by the foot.
