Re: [CAD_CAM_EDM_DRO] Machine base question

NC Circuit board drills were at one time and possibly still are built this way. A few years back there were an abundance of these machines around for dirt cheap or free.

Has anyone used or considered air bearings running against a surface
plate as a support for a gantry?

I assume with small clearances they should be pretty stiff when two
opposed bearings (on opposite sides of the plate) work against each other.

Comments, thoughts, etc ate all welcomed.
