puzzler: vertical damper problem

[reggaepass at aol.com]

I brought my upright piano tilter along just in case this was it....but 
it wasn't.

  For those who didn't see the post yesterday announcing the answer to 
this puzzler, here it is.

  ....and the winner is: Alan Bernard. The action rail split at the 
treble-most damper rod hanger bracket (the one that bears the brunt of 
the push from the dowel). Taking out lost motion by turning the nut 
down only provided more leverage to split the rail further, so that 
highest bracket moved up and down with the kindling it is attached to 
(rather than staying put like its supposed to so that the damper rod 
rotates).

  Thanks to everyone who responded to this. It has been yet another 
learning experience!

 Alan E.

 Aha (?) ... split action rail that holds the damper rod hardware?

  Screws stripping out on the bottom board on the piano, creating lost 
motion as the bottom gradually lowers?
