The reflector is made from a 2-foot by 4-foot (61 cm. x 122 cm.) rectangle of reflective material, with three scissors cuts as shown in the template. Overlapping the cuts as shown produces the proper shape, and the material is then secured with two brass paper fasteners (brads) inserted through holes punched with an ordinary paper punch.The windscreen (barely visible in the cooker photo) is made from a 2-foot (30 cm.) diameter circle of .020-inch (0.5 mm) UV-resistant polycarbonate film. For increased rigidity, a radius cut is overlapped two inches to form a flat cone like an oriental hat. The overlap is secured by an "R-clip" (a cotter pin that looks like the letter "R"), which is inserted into holes (punched in the windscreen with a paper punch) and then attached to the reflector material. The windscreen makes the cooker quite rigid in windy conditions, and creates an "oven-like" atmosphere around the cooking pot. Cooking sleeve. Instead of a cooking bag, the black cooking pot is enclosed in a "sleeve" of .020-inch (0.5 mm) UV-resistant polycarbonate film. A 6" x 36" rectangle of polycarbonate film is rolled into a cylinder slightly bigger than the cooking pot, and secured with ordinary paper clips. The top rim of the cooking pot rests on the top edge of the cooking sleeve, which insulates the cooking pot and elevates it off the surface of the reflector, allowing the sun to be reflected onto the bottom of the pot.
