Tobias Posted January 24 Posted January 24 (edited) Help! A weird problem has occurred with my almost brand new (2016) Dipper concertina. The c# on the right is "singing along" when I play the d afterwards. Same issue with the a on the inner row and d on the middle row LEFT hand side! The problem came, after I tried to fix a reed that was sitting a bit too loose in the reedpan (the same d-note actually). So I put in a small piece of paper, and the reed isn't hoarse anymore. While the box was open anyways, I pushed the reeds, I could see were a bit loose, a tiny bit firmer. And when the concertina was put back together - this other issue happened. Har anyone experienced this before? And have en idea of what the problem /solutions could be? I would really appreciate it. I recorded a video to show the problem, but the file is too big. Here is a link til the video:https://photos.app.goo.gl/67ueLKpT8w4JJ2af7 Edited January 24 by Tobias
Tiposx Posted January 24 Posted January 24 Did you tighten the end screws to the "right" torque? Or perhaps the chamois gasket is leaking air between the chambers.

Or perhaps the chamois gasket is leaking air between the chambers. we tried to test that yesterday. The chamois appears to be tight - but we could detect a tiny tiny difference in the tightness in one part of the instrument (same part as the isssue is). I tried as well to adjust the screws, a bit looser on the other side, and a bit tighter where the issue is. Maybe I should try a little more:) because it sounds like, this is the only thing that can be wrong, if the chamoise is tight, as I presume it is.
RAc Posted January 24 Posted January 24 there are little wooden triangles that support the plates in the casing. If one of those should have come loose, you can tighten the screws as much as you want without it making a difference.
Matthew Heumann Posted January 24 Posted January 24 Dipper instruments tend to have tight tolerance (thinks precisely snuggled together), so it is possible that this is not an "air" problem, but rather one pad catching on the side of another. I'd take the end grill off and check the spacing between pads. Likewise if a pad has rotated a bit on the end of the lever, it may not seal down right away. Similar problems may arise if a lever is catching on an adjacent spring. I've had all happen and its frustrating trying to find the offending culprit. Good Luck!
