lucayala Posted April 19, 2022 Share Posted April 19, 2022 hello! this is my first participation in this forum, but I've being read it in the shadows for a long time. I'm from Argentina and I'm trying to design a bandoneon in 3D print technology. I hope no one thinks this is out of place. the bandoneon is a concertina too. a german one... I had read in this forum about some types of steel to make tongues (or reeds? what's the correct word in english? some people say "tongues", some people "reeds". sorry, I'm not a native english speaker), like 1095 high carbon steel. that type of steel is possible to buy here in a very thick format, and I'm probably won't be able to do the procedures to convert it to the correct thickness for a bandoneon/concertina tongue. I can get very cheap thin brass sheets, like some 0,7 or 0,8mm thick sheets. but here my concerns: is this ok? can I just cut some 0,7mm brass sheet and make a tongue out of it or do I need any procedures first? I've read in this forum people who cold hammer the brass to harden it, but a 0,7mm sheet hammered would end up being too thin, right? can anyone point me in a good direction on this matter? here the world of the bandoneon is very miserable. nobody wants to share anything about the instrument. anything. I had to disassemble my instrument and measure piece by piece in order to design it. no one helps me at all. and nobody wants to say anything about the tongues. can I cut the brass sheets and make tongues out of them or do I need to buy thicker sheets and cold hammer them first? or can I buy another kind of steel and make tongues with laser cutting? is this possible? I'm completely in the dark here thanks a lot Quote Link to comment Share on other sites More sharing options...
