I am TDing a show where I am also building most of the set. Last week I made giant, lightweight screens (.75" x 2" wood frame) that are 9' tall by 3' wide. There are three that were intended to slide on three sets of stretched aircraft cabling. Easy-peasy, no touble so far. It turns out that the same three screens will now be used like doors. The three screens are lined up side-by-side, two open in together, like double doors; the third opens in by itself. Here is my problem - I have structure on either end to simply hinge the "door" screens or to put cabnetry pivots in top and bottom. The problem, I don't have any structure for the middle door. The screens are side-by-side, so it negates putting a 2x4 piece in from the bottom. The back wall is 20 feet away through masking curtains 10 feet away; The ceiling is 4 feet or so above the top of the screen. Oh theater geniuses, any thoughts? The wood of the screen is REALLY thin (since it was built to be suspended, rather than torqued). We are already over budget so re-building is not an option, neither is buying 12foot 2x4s. My original inclination was to sink metal pivot locks and have the top and bottom corner pivot on metal pegs/bolts. Qua?
