Once the foam was glued down to the MDF, since it was contact adhesive, there was no hold up: we could immediately move on to routing out sections to bury the little strips for joining the face ply on. Now you begin to see the "negative detail". It's basically an visual break in the wall.
	Then it's a big clean up prior to gluing down the expensive (and very thin) face ply.
	We also painted the (pale) jointing strips of ply red, so there wouldn't be a white line between the sheets. Oh, I didn't mention we left this 3mm gap everywhere, (a little negative detail). This was to help disguise the doors and moving walls. Obviously doors need a little gap to work, so we used the same gap around every sheet. Since these fragile sheets were also contacted down, fitting them to such minute tolerances was a bit nerve-wracking. But it worked!
	The support / hinge system also took a lot of thought, especially since the brief included getting a wire into each door, to liven up a light in the display cabinet in the middle. Eventually we settled on individually made up pivots, more about them below, and a wheel at the outer extremity. The first wheels were a failure, we had to go back and rebuild them with stronger hinges, better quality bearings (that could handle a bit of side thrust), and very decent guides. The springs are simple valve springs (from a car). The hinge is just a very strong domestic door hinge. The guides are solid steel plate! You can adjust the pressure by winding up a nut, compressing the spring.
	The wheels needed to be sprung to cope with the local deviations in the floor (about three quarters of an inch). Since the door rides very close to the floor (varies from 5 to 25 mm, due to the waves in the concrete), the wheel housing is high. It also has to be quite solid. It's a bit of a trick to support it when the "structure" is so lightweight!
