Here's a handy carrying case for your movie reels. Made from 6" self-locking stovepipe, it stands 17 ½" high and accommodates 24 ordinary 200-foot reels.
After compressing the pipe until it just suited the 5 ¼" diameter of the reels, I cut it lengthwise into halves. Then I hinged the parts together, drilling the metal and using rivets to attach the hinges. On the other joint, I installed two suitcase catches, locating these to take care of the overlap.
Inside each end of one half, I screwed a 5 ¼" disk of 3/8" plywood. A chain pushed through a piece of hose is fastened to one end as a handle. -Norman Maire, Beaver, Pa.
