Maybe you could convert a car washer? Might be washers of different style, but my friendly gas station scrapped their portal style washer some months ago. It traveled on floor rails and was big enough to cope with large vans.

Hi all ! Now this is just a concept to provoke some thought. What about an "open-frame" machine? Say we make a wide "railway line" of chain on a large concrete floor - bolted down to the floor like (maybe raised 100mm or so on steel stand-offs). Then we construct a "trolley" style gantry the width of the fuselage, or wing-chord, which claws it's way along the track with LARGE sprockets, running on the floor with rubber wheels. A strip of angle or some such down the center of the "tracks" to provide steerage for the trolley-gantry Accuracy dependent on the floor being level, but for this project 5mm should be easily accommodated.
