Ok take a look at this crack. This one was hard to find and I really did not want to find one. It is on the lower tenon joint, the one that holds the bell. The crack extends about .5 in below the tenon cut down into the bore. It is only a through crack in the tenon itself. It is a very small crack and seems to be stable and if the crack got bigger it would not run into a tone hole. The bell compresses this crack so I don't know if it will grow or not. I think it would take a while before it caused a problem even if left alone. The question is what should be done to it if anything? I would think this would be a good one for super glue since the crack is so thin that epoxy would not penetrate. I think the crack is so thin that wood powder would not penetrate into the crack. I did some reading on super glue (cyanoacrylate) and it looks like it will work but it does weaken over time with water exposure. Looks like the crack started at the tip of the tenon where the chip is. The first photo points to the crack and the chip. Here is a link about super glue type adhesives.
