I just was not satified with my Z Axis so i redesigned it and I am now using skate bearings It is very smooth and easy to move compaired to the other one I had In posts #41.
This has two 6" bearing slides and I managed to design it in such a way as to use U bolts and another bearing on the backside to keep it snug against the 3/4" Drill rod.
I am very happy with it now, and it has no racking in it at all that i can tell by trying to twist it by hand.
The travel is 6 3/4"
