I posted this in another forum as well and thought I would share it here as well for anyone who wants to reduce their compound backlash. I installed new nuts on my cross slide and compound slide today. With a very slight adjustment to my cross slide nut, as per Cal's method, my backlash is less than .001. Very happy with that. However, after installing the new compound nut I still had .01 backlash and there is no provision for adjustment. Rather than purchase a new compound slide screw, I decided to cant the nut with a shim. The brass shim is .015. I needed to take a little off of the top of the brass nut with a file in order to maintain clearance to the slide. I now have a backlash of .0015 on my compound slide. Easy low cost fix. I couldn't figure out how to post a pic here from my ipad.
