I am seeking mechanical specifications for a gantry based robotic system.
The intended use is shape digitization (vehicles, furniture, architectural
bits) and reproduction (molds, actual bits).

Specifically, has anyone out there actually done the machine work required
to build an accurate gantry system.  Hopefully there is a way around using
old milling machine ways.  We are hoping to cast the main pieces out of
a stable urethane/metalic matrix which is bonded to stainless, and then
in a feat of "and then a miracle occurs" be able to machine the stainless
to an accurate flat shape.

Some say that a great degree of accuracy isn't really necessary, just a
big table of all positions and where they actually are (kind of a big
servo correction table).

What we hope to end up with is a room sized (8 m. x 4 m. x 4 m.) gantry
to which we can attach either digitizing arms, or cutting and removing
arms (water jet, milling head, saw, knife, carbide blaster, fiberglass
chopper gun).
