alexwhanks Posted October 30, 2019 Share Posted October 30, 2019 Hey all, I've been working on restoring an old Concertina I picked up at an antique shop, and one of the (many) problems I'm running into is what the button caps are made of, and how they were put together. I attached an image below, does anybody have any knowledge on this, or spares available I could pick up? Link to comment Share on other sites More sharing options...
alex_holden Posted October 31, 2019 Share Posted October 31, 2019 Maybe zinc, or galvanised steel? Is it magnetic? They were pressed from discs using a custom die set. I have an old blog post about how I make mine: https://www.holdenconcertinas.com/?p=1341 If you only need a small number it would be easier to turn something similar from solid bar. Aluminium would work but would look a bit different from the originals. Link to comment Share on other sites More sharing options...
