I am currently in the process of cleaning up a series 1 BP. I am leaning towards replacing the x and y feedscrews and nuts as they are badly worn in the centers, so even though I can adjust to .005 backlash on the ends there is close to .080 on the x and .025 backlash on the y in the centers. I have a DRO on it but the slop bothers me. My question is what nut to purchase? There is he 2 piece and I also see a one piece which is slotted twice in opposite directions at the center. it seems the double slot design will compress like an accordion allowing greater adjustment then the original single slot design. They are far more expensive than the 2 piece design so I was wondering if there was any advantage to the more expensive nut? my machine currently has 2 piece nuts.
Thanks
