Building a backyard cine screen

Most of the backyard home-built movie screens I've seen are overbuilt wooden structures that take up a huge amount of room to store when not in use or are flimsy PVC tubing affairs. My answer is to use steel tubing. It is strong, relatively inexpensive, and easy to set up and store. Here is how to build a fast, cheap and solid movie backdrop using 10 foot sections of electrical "black pipe" conduit for the frame. They come in 10 foot sections ready made and are available at Lowes and Home Depot. The advantages of black pipe is it can be setup in 6 minutes. Disassembly is also 6 minutes. It takes almost no room to store. The key is to use half inch black pipe conduit, which is actually about 1 inch across with 1/2" internal size. Here are the parts. You need at least, 8 bungee cords, 12 feet of steel cable, two half inch black pipe elbows and two half inch black pipe connectors. Three 10 foot black pipes.
