Steinway Sostenuto

[John R. Granholm]

List--

I have a sostenuto regulation problem with a 1953 Steinway D.   
Depressing the sostenuto pedal with no keys down lifts about half a  
dozen dampers in the tenor and treble sections.  The adjustable brass  
hangers which allow the sostenuto rod to be moved back and forth are  
set all the way back (away from the lifter tabs) in tenor and treble,  
and these few dampers still come up.  The bass end of the rod has  
some adjustment room left and works fine.

I know I could shift the action forward a bit, but I hesitate to do  
that and alter the striking point.  The lifter tabs in the back  
action look fine to me, nothing out of whack.  I've considered  
reaming out more space in the slots in the brass hangers to allow the  
lifter rod to move a bit further back, but I wonder if I'm missing  
something.

If it matters, the action on this piano was rebuilt with Renner parts  
about 6 years ago.

Any suggestions?

Thanks!
