[CAUT] Thumping Baldwin SF

[David Love]

You can try cutting the back edge of the back rail cloth free from the key
frame if it's glued down. Sometimes that helps the key donk.

I've had them "donk" no matter what I did, usually on release. 
In these cases, it wasn't bedding. The keys (or something) 
would ring like xylophone bars. Did it in the piano, and on 
the bench.
