I've been tapped by my Home-School Association to build the runway for a spring fashion show. They want a 6' x 28' platform, 40" high, freestanding. It will be appended to the stage in the gym/cafeteria/activity center, but it will have to stand on its own. Since it's a church-run school and a fundraiser, the materials budget is nearly nonexistent (translation: I'll end up buying most of the materials out of my own pocket). This is intended to be a modular, reusable product, with individual parts that are small enough for two people to set up, take down & move, but sturdy enough to walk on. My initial thinking is to use 7 sheets of 3/4 plywood trimmed to 4' x 6' size for deck. I'm considering making the legs from 16" x 40" boards cut from 1/2" plywood - two at each corner, fastened together, should be sturdy enough to prevent wobble.
Things I haven't quite figured yet:
- how to hold all this together- Ideally, each section is self-contained and requires no tools for assembly. Hinges with removable pins are an option, but I'd need 84 pair, (the way I'm thinnking of doing it.)
- how to brace the decking - 3/4 plywood is strong, but it _will_ flex under an adult's weight when spanning 40 inches (the distance between legs)
Any suggestions?
