Fixing a broken bandoneón wasn't on my bingo card for last Friday! (Mostly because I don't really do repairs at all! But if I do a repair, it's usually more trumpet shaped!)
Turns out I'd met the customer years ago when he played bassoon in a trumpet and organ recital I did. Now he's dabbling with this beast...
Problem was that one of the little springs connecting the buttons had broken. Managed to extract the broken fragments, measured up and looked in the spring master catalogue. Too many options and a bit much to read so a called them up. Bit of an argument with the lady on the phone where she was adamant I needed a compression spring and wouldn't listen to what I was telling her! It's an expansion spring but it doesn't have loops on the end. Me cutting the loops off was obviously sacrilegious 🤷
Realised I had some spring wire in the drawer so I just chucked it in the lathe and made one myself!! Pretty chuffed with this fiddly little spring, it's only 2.75mm OD, 0.35mm wire and only 6mm long! Made him a couple of spares while it was set up. Have to try and fit the soundboard back into it now 😳
