[CAUT] Steinway dampers: The aftermath

Friends,

Have just returned from my client's studio ... the 'B' with the  
oinking/buzzing dampers. Thanks to your sage advice, the buzzing of  
damper wires against strings (in the bichord section) was an easy  
fix.  Adjusted the 'pressure bends' to create some side-bearing  
against the guiderail bushings.  The challenge here, due to 'less-than- 
stellar' drilling of the guiderails (uneven spacing), was that some  
had to bear against one side of the bushings, some the other in order  
to have them rise vertically and as close as possible to the center  
point between adjacent strings.

Decisive damping was quite another issue and perhaps I might open up  
another thread for discussion here:  In spite of precise alignment  
(side-to-side, fore-and-aft, vertical), almost all the bichords and  
the lowest 4 tenor trichords still ring on for the 'split-second-too- 
long' that draws your attention.  I have fussed with the alignment,  
string spacing (on the trichords), string level, damper wedge profile  
(squeezing to create a sharper wedge) to the point of diminishing  
returns.  I have listened to other similar pianos, some of which  
display the same imprecise damping in this area ... some less so.   
Have I missed something?

This piano is a mid-70s 'B' (teflon) which has recently been  
retrofitted with OEM Steinway parts, including damper action.  The  
latter is clearly not identical to the original (although the spacing  
and alignment worked out very well) and I didn't think to compare the  
'downweight' of the new levers to the originals.  On some of the  
offending dampers, a little more weight (applied gently by finger)  
reduced the 'oink' ... but not all.

Similar to ongoing discussion of the many choices available in  
aftermarket hammers, would you mind sharing your preferences for  
currently available damper felt?

Regards,

Stan Kroeker, RPT
