Another X Axis Mod

I have been looking at the X Axis mods on Thingiverse using the roller bearings and decided to take a different slant on the subject.
I decided to try some linear ball race bushes as used on CNC engravers and routers.
I managed to track down some 3/8 inch id bushes with an od of the exact size that fits the existing holes which are holding the plain bushes.
The X table now moves as if it is floating on air.
After seeing this result I intend getting another two to put on my Y axis.
