Our shop uses a Hollywood Oat style of construction. The 15;'a" studs are perfect for tius use. In fact, the slightly narrower edge is great for storage. Figure 1 shows a fabric covered door Oat. We found that covers can be hard or soft, and that the lauan and plywood covers need not be glued. Styrofoam attaches best \"ith adhesive, especially when carving it after. Adifferent technique instead of the traditional stapling or glUing to the Oat face works best when applying fabric covers and helps avoid tearing. Instead, the fabric is pulled around to the back of the urut and attached with pan-head screws. One advantage to this technique is that no glue residue remains on a recycled frame once the muslin or other fabric is removed. When hanging practical doors or windows, we run into the san1e challenges as with standard Oats-aJ1d the solutions are the same. Traditional bracing (we build L-jacks from steel as well) will nlininuze shaking when doors are slan1med and proper cripple studs under the sill will bear the weight of an actor.
