How can I fix the broken bellow?

[zqd9853572002]

My accordion's bellow is broken at the corner, not sure how it happened but the bellow must be aged definitely. I am not sure how much to replace a new bellow here but guess it cannot be cheap. So, are there any ways I can fix it in some simple method, such as using tapes or paper to seal it? I am not sure...

Here are some pics

Here's an earlier thread on the subject:

Replacing all of the metal bellow corners.

Is it feasible doing this on old bellows? I removed the bellows and shined light from the inside and the gussets look fine and aren't to worn. I was thinking about removing the old bellows tape and corners and replacing. I realize that the metal corners on modern accordions are put on a press...

Nasty looking and impossible to fix? As the pictures shows, even major holes in the bellows can be fixed.

The cardboard seems broken at this corner, as well as the fabric... What you could do is glue a piece of thin goatskin inside the corner. (That's the same material as used for the inner side of the corners, clearly visible in the picture.) You have to be careful that the goatskin is glued all the way around so as to have no air leaks, while also ensuring you get no glue around the seam in the corner because when the glue dries it hardens and would crack when you try to open and close the bellows. When the corner "works" again, put the metal corner piece back on: pry it open a bit, put it on, then clamp it firmly with something like bolt cutters (to press on the sharp edge while not pressing on the round part of the corner). Putting on new bellows tape is the last step.
