Hi,
My mill, lathe etc all came with a small piece of rod for the gib locks cut at 55 (or whatever degrees they choose to use) to match the gib angle as described earlier in this thread.
I took these out cut the 90 degree end off a bit, then drilled the end to leave and indent for a metal ball to sit in. I also drilled the gib lock bolt the same to match the ball.
When finished with a few drops of oil it works with just the lightest nip up of the gib lock, much better than it used to be with all the friction of metal to metal.
You will always get some movement on your DRO when tightening the locks, but it shouldn't be much. If there is you may need to check you gibs for tightness, they should have a light drag when set right. One way is to slightly tighten the gib lock when your getting close so it has drag, you will then find it doesn't move much at all.
