Hi Paul.
From my point of view as a cnc wanabee, that is the crucial problem.
Since started down the cnc path, I've collected quite a few bits and pieces, including linear bearings from ebay.
I've found that with my lack of machine tools and engineering experience, the "skate board" bearing approach allows me to build each trial rig with adjustments built in to overcome these shortcomings.
Needless to say each failed rig has taught me quite a lot

It's like doing jigsaw puzzles in the dark.
Enjoy today's problems, for tomorrow's may be worse.
