When I was a boy my father brought home from work a telegraph sounder replica kit. He was the director of the library for a local college and the sounder kit was one of several museum quality reproductions of 19th Century technology the library had acquired. The lovely brass sounder must have made a large impression, because I have wanted one for my own ever since.
Well, here at the The Workshop if you want something, you make it. I started my quest by cruising Google image search for pictures and diagrams of telegraph sounders that matched my recollections of the one my Dad brought home. As it turns out all telegraph sounders are pretty much the same so it was an easy task to collect a bunch of photos and drawing from which I could extract design details and dimensions.
