I've recently bought an ex-demo (read as: brand new apart from 2 small chips on paint) Warco WM16 mill/drill for a bargain price of £750. Having weighed up the price of power feed and DRO vs the cost of a CNC conversion, I decided to go CNC. This is my first ever build, however I've worked in engineering since starting my apprenticeship 19 years ago.

In the section of the book on enhancing the precision of the mill the author covers installing ball screws in the X-Y & Z axes but missed an easy and readily inexpensive enhancement, which is the installation of Fenner or Segmented belts to reduce bearing wear and produce better finishes. Many of the readers may be in a position to purchase a mill.
If you want to separate the quill from the ball screw, you must remove the 6 Allen screws that attach the ball screw to the top of the quill. Be very careful that you don't let the ball nut unscrew from the ball screw. Once all the screws are out you can separate the two halves.
engine lathe or to its current turret lathe configuration. I started by partially dismantling the Logan, removing the carriage, turret, quick-change gearbox, and all the gearbox drive gearing. As I wanted to be able to return the machine back to an engine lathe, I didn't want to make any permanent modifications to the structure of the machine.
A CNC conversion replacing the lead screws with ball screws should improve the quality quite a bit. Adapting a 3 phase motor or converting to a belt drive with a 3 phase motor should get the speed up quite a bit and give me the best of both worlds..

Proper ball screws have two nuts with a spring between them to take up almost all slop. My 1977 model Boston Digital CNC mill has about .0005-6" backlash due to large screws with spring loaded nuts. A friend spent a ridiculous effort and money to convert a good BP to ball screws and add CNC. He has .002" backlash.
