That is why I was thinking "Air Bag".... Some of the Radical Automobile
lowering kits now have DUAL air line feeds up to 1.5" NPT. That moves
air pretty well ! They have electric valves just as capable because
these guys like to "jump" these cars.

But, I think they only run up to 6" diameter bags. Search for a place
called AIM Industries, or pick up a new "TRUCKIN'" magazine and look at
the ads. I was thinking 8" diameter would be better.

The Subject looks to be a pretty neat little cnc project. Wouldn't mind
trying it myself someday.
