Hi John,

I bought C2 ground ballscrews, to replace leadscrew and cross slide, on ebay , then made a backing plate, that replaces the rack, to hold the ballscrew brackets.

I have since sold the lathe but the new owner did not want the CNC kit so if you are interested i have the ballscrews for both X & Z axis as well as the brackets to fit. the only thing still to do is to make the Ballnut carrier for the saddle.
