Any chance of doing a morse 'sounder'? This is one I found in a country museum in out back South Australia. Apologies for fuzzy picture. It was through the glass case.

The problem is that a sounder requires large amounts of metal and wire. The coils need to have a metal core, and the sounder arm needs the mass provided by the metal to be audible. There would be very little to print aside from a basic frame to mount everything else on.

Yes the sounder is a fair bit of electromechanics. I came across a really nice morse code key for $35 Australian and would love to find a sounder to match it (especially around that price), but they are a much rarer find. So I am not holding out much hope. I have added a photo just after I had finished cleaning it up. below. I was very pleased with it. I have also found another photo of another sounder which has more of the mechanics that maybe could be printed, with the rest being in plastic (it models brass in as much as that it is non magnetic!! :-) ) It does not have the wooden hood to direct the sound I guess, but who ever took the photo got a good look at the mechanics. What do you think??
