Grand hammers breaking off when keyframe is pulled

[PIANOTECHNICIAN at aol.com]

I'm not talking about a hammer breaking off (when a grand action is  pulled 
out) because the hammer head is too high, thereby getting broken off by  the 
pin block. I always check for clearance, as we all do, before pulling a  grand 
action. I'm talking about the part of the plate that runs perpendicular to  the 
pin block, and too close for comfort to the hammers at the treble break. The  
bottom of the plate extends down, below string level.
Can you picture it now?
