Here we have a back brace that was loose and sounding off (vibrating at the wrong time, like there is a right time) I injected a bit of hide glue under the brace and put a Brace Jack on it to push it down on the back. The wet spot you see is from wiping the excess glue with a wet rag. Once it's dried I'll remove the Brace Jack and string her up..
I got lucky on this one. Not so lucky on the next one.
