Will,
When is the last time you saw a Baldwin with crown in the treble? Just 
out of curiosity?


Someone at Baldwin was at one time convinced that bridges needed to be 
crowned. Combining crowning and capping in one "efficient" operation, 
they made bridges in two layers of about equal thickness. The root had 
the grain along the bridge, and the cap was cross grain. They dried the 
wood down, glued up the panels, and cut out the bridges, which then 
crowned as they rehydrated. I'm with Terry. If it's not causing a 
problem, leave it the heck alone. A "fix" of sorts by drilling holes 
through the cap, injecting glue, and putting in screws is good for 
looks, but I don't know that it would be particularly beneficial to the 
piano unless it's currently making noise.
