More Giant Air Horns
Over the years FARM SHOW has reported several times on how I turn giant, 2-ft. long cast aluminum air horns into an attraction at antique engine shows (Vol. 39, No. 5). I recently put together 2 different sets of 3 giant air horns made from public address speakers. They’re hooked up together and mounted on a pipe stand.  All 6 air horns are made out of 3-in. dia. pvc pipe for the body and have 8-in. diaphragms made from plexiglass. However, the pipes are of different lengths in order to produce different sounds. The horns sound like ocean liners.
  I also made a much bigger, single air horn using the cast aluminum housing from an old public address speaker. It measures 1 ft. tall by 2 ft. wide and sounds like a foghorn.
  I hook the horns up to a large air compressor tank in the back of my pickup. (Dave Dam, 111 N. Buena Vista Rd., Eau Claire, Wis. 54703 ph 715 450-2943; ddamwhistler48@gmail.com)
