  • Gong ? / Chime

    I luv HotFoot's gongs.
    I love the wire gongs (Chimes) in a mantle-clock even more.

    I wonder what I would get, if I took a 20 foot rod of 4140
    and wound it proportionally to the clock-gong shape and struck it with a neoprene mallet?

    You might make one by uncoiling a car coil spring for a large one, or get a roll of really thick music wire for a smaller one.



    Here's a video of a clock gong mechanism playing a tune:

    I want to make one of these Cajun triangles when we get the gas forge finished.

      Thanks , viewed a couple more, doesn't seem to be a magic number of turns.
      Maybe the more turns the more complex the sound, the fewer the cleaner??
      I wonder!

        Go for it, Vice...let's see how it sounds! I would think if you heat it to roll the shape, it will lose temper, and sound much duller than if you cold-rolled or stretched it. I'd start with four feet and work up...'depends on the diameter of the ring, I guess.

          Here's a short article about how to make a clock gong, from 1891:

            Hey, Pops! was that one of your textbooks back in school?? All kidding aside, that really makes for great reading!! That's a book that I'd like to have along on a plane ride (if I ever ride one again!)...That and a notebook...it really gets the creative juices flowing!

              Hotfoot, if you do an advanced search on google books and check only the "full view" books, you'll find all kinds of old books. Just search for "mechanics" or "shop practice" or "workshop practice" or "machining" or the like. For example, here is the Starrett book for machinist apprentices:

              http://books.google.com/books?id=GYxEAAAAIAAJ

              I'm willing to bet that some of the old books about oxy-acetylene welding are just as valid today as they were then.

                I was pondering that too??
                A spingyness or a stress-free state.
                What effect would there be on sound / resinance?

                  Fixed point in the inner end, fixed point in the outer end.
                  How many coils? Multiple coils?
                  What are you do'n trying to male my head explode?

                    The inner mounting point near the striker is fixed, but not the other end. Seems that about 4 coils are recommended.

                        92 outer? On the left is the gong, on the right and above is the striker, an independent part. Apparently an offset or stalk on the base mounting point is advisable for the sake of resonance. There is at least one old patent on an "isolating" type mechanism to anchor the chime to the resonating plate or base to prolong the sound. (Trust me, I'm a geek.)
