Good questions.

Deviation vertically is the critical direction. 

For expensive, I'll put a $500 budget on it.

Thanks for the suggestion of the supported rail.

Defection in which direction?



Define ‘expensive’, especially in the context of no deviation.



Supported rail is pretty cheap these days: https://www.aliexpress.com/item/one-set-SBR16-800mm-with-2-blocks-sbr16uu-Linear-Motion-guide-supported-rail-SBR-linear-shaft/32726991216.html



Bolting a couple of those to something reasonably stiff might work.

Subject: [CAD_CAM_EDM_DRO] 22" travel single axis suggestions




Considering creating a special application machine that would require a single axis with 22" of travel. It will not have to carry more than 10 lbs, but needs to have less than .0005" or better .00025" deviation under the spindle through out the entire travel.



Not worried about how to drive it mechanically or electronically. Just looking for ideas on the least expensive way to build physical parts of the stage.



Ideas?



Thanks,
