Tim, take a look at McMaster Carr part numbers 6250K32, and 6250K34 on their website mcmastercarr.com. These two items are within your $500 budget. The rail can be mounted to something solid, and shimed to be true to your specifications. There are many other sizes and options to choose from. One of the larger rails may even work unsupported throughout except at each end.

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:
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,
