Where’s the Steinway B?  Oh, it’s out by the back Porsche….,
 




 


Hey Jim
  Did the attached pictures help answer any questions. By the way both Bshave the New Weickert felt hammers.  David brought up a good point aboutvoicing.
 IMO This pianos can be voiced a variety of ways. But the two pianosmentioned although they are both Bs but built differently...I truly wonder ifthey could be voiced to be identical or even similar.  Any way Davidssoundboard resonance reduction  thought is apparent in both pianos. Yes still much to learn, explore and have fun on the journey.
  The big thrill is to hear music coming out of a new re-whatevered box.Do I hear a cheer?

 





  It's dark, powerful and voluminous 

are you by chance a wine taster by trade <G>  no
  my tonal envelope is power with out noise. Or as Starr Taylorsays" Without the strident clang that permeates the piano tonal landscapeof today"  Predominant fundamental balanced by upper partial claritybut no clang and little percussion on hammer impact sound.  I seem to beallergic to it
can I take this to mean prominent fundamental and lower partials with a reducedprominence of the uppers?




The design spec: is a grain angle that follows the long bridge(approx 30 degrees off the long side)


hmm.  Yes for me I've always measured it off the spine. Easier. Stwymodels S,M,L,O are 45 degrees,(some )s in the 30's) and A's thru Ds are 40degrees with some anomalies

,serious curved cut-off bar,

where does the cutoff end inrelation to the tenor ribs? See pictures
