Tearing into my B-port and trying figure a few things out. While I enjoy the work, I have a ton of other projects to do and would like to have it operational sooner than later. I've looked at parts, and for under $250 I can replace both feed nuts and the cross feed screw. Most of the end play is in the Y axis. In the parts break down they show both one and two piece nuts. I checked past threads and found some info, but would like to know from those who have been there which is best, and why. There was also mention of a two piece nut with a spring used on a lathe, which remembering after I removed the nuts from the casting, led me over to my collection of misc. springs. Low and behold, there was one just the right diameter and length that in my tiny mind seemed just right for the job. My thinking is, get the two piece nut for the X axis and install them with the spring in-between to maintain Zero backlash everywhere on the length of the screw regardless of regional wear. I realize one of the nuts would have to be lapped to allow a slip fit, and both would have to be shortened some. Does this sound at all workable? Would it cause premature wear, or affect machining operations in any way? Just throwing it out there to see what those more experienced than I might think. Thanks, Mike
