[CAUT] Friday puzzler: Won't play on hard blow

[Edward Sambell]

Could the jack be getting trapped between the knuckle and the felt in the end of 
the repetition lever? Try reducing aftertouch with a shallower keydip. Also, if 
a nearby hammer moves under a heavy blow, the balance rail may need re-bedding. 
Test by placing one's free hand on the keys at the balance rail about an octave 
distant from the offending notes. There should be no feeling of movement when 
the notes are struck. However, if this is a problem, it is unlikely to result in 
the one being discussed.

Perhaps a somehat loose center pin in the whippen flange allowing it to flex 
enough that it catches on the neighboring knuckle/whippen?  
I think we are a product of all our experiences.
