[pianotech] Bridge separated from SB

[Daniel Carlton]

Hey all

I've seen two pianos lately with treble bridges separating from the  
soundboard; the separation was in the middle of the bridge on either  
side of the tenor/treble strut, not on the ends (make sense?). What  
are some possible causes and remedies?

Also, I need a definition again for bridge roll.

Best
