Have a picture. Question to follow.
This is the set I'm building. Relax... I have a week and a half before we open. Cast of 7, community theater, show runs for 10 performances plus 3 dress rehearsals
The ramp indicated by the red arrow folds up, and the two walls indicated by the blue arrows fold in. The whole thing is a cube that opens up to what you see here. The ramp wall is 12' wide and 11' long/tall. Up to 7 people walk on it, although I don't think they're ever on it at the same time.
My first thought was to use some aluminum I-beam extrusions I have. I have 4 that could span the 11', so I would put them at 0, 4, 8, and 12' as stringers/studs. Then in between I was planning on several 1-by spans between the aluminum, skin it with luan, and fill the cavities with 2 lb urethane foam. Unfortunately, that will cost about $600 in foam.
Enter idea #2. Have another picture:
I need to make this thing rigid enough to hold some people, but light enough that two people can fold it down/up. Is there some sort of adhesive I can use to laminate some polyiso insulation sheets together, then use that same adhesive to make a stress-skin platform by laminating luan onto it?
I know epoxy would work, but we'd be spending as much or more on epoxy as we would the expanding foam.
