Hi, all. I'm working on a set design for a local community theatre. I want to try something new, but I'm not exactly sure how to build it. The main restrictions are that it needs to be simple to build and as inexpensive as possible.
See the drawing. The main part will be on wheels. The three wings would ideally rotate 300 degrees and even fold into the center structure when not in use.
Any suggestions on how to build and/or how to modify the design would be welcomed.

You could use a piano hinge to attach the rotating boards to the "main part." There are three big problems I see with this design:
1. Anywhere you have a hinge won't be paintable, so you could have scenery gaps. You might be able to hide the gaps if you're hanging something rather than painting the actual pivoting piece of wood.
2. If you hinge the moving pieces, they will be able to fold flush to one part of the "main part", but not the other (because the wood has a non-zero thickness to it). Despite that, it should be possible to build this contraption such that all three pivoting pieces can fold flush for storage or transportation, but they will only be able to fold one way. So, you won't get 300 degrees of rotation, but you might get 270 or so...
3. How do you create the "main part"? You either need to butt the edges together and put some 2x framing in the middle of the triangle as structure (which means there is no single point at the vertex of the triangle, which means there's no way a pivoting piece could come anywhere close to folding flush to two sides of the triangle), or you need to somehow miter at least one of the edges of each piece (which means hinges would be screwed into the thinnest, weakest part of the entire thing).
