Dear Sir:
When I built my 3 axis table I too worked toward an economical approach. I used cold drawn flats for the ways and used standard bearings with eccentrics on the carriages. Cold drawn flats are dimensionally quite good and the cost is right. If you would email me, I will sent back photos of my ways etc. My drive is rack and pinion.
Regards,
