Steinway B Scale Conversion

[Erwinspiano at aol.com]

  How do we rectify in our thinking & scaling  the 9 wrapped tenor notes on 
the long bridge of an Baldwin SF  10. This is a piano similar in length to the 
S&S B. To my ear it  only needs 5 unisons wrapped. I just came away from a 
nice one built in 1987  & it's a good sounding scale /piano. What am I missing?

On the contrary I have every reason,  and there is nothing arrogant 
about my comments.  Let others  calculate the tension of that scale 
and see who they think has the more  reason.  The lengths for the 20 
notes on the bass bridge are printed  below.  When I see a bass scale 
that requires the wire for the  greater part of the scale to operate 
at over 80% of the actual breaking  strain, as high as 86% for one 
note, I know I'm looking at a recipe for  disaster.  I am at present 
being asked to replace, one by one as they  break, the original 
singles on a 7' Bšsendorfer that is played for 6 - 8  hours per day by 
a young concert pianist and has strings under less strain  than yours 
but much too tight.  The tuner is sure he is going to  break more and 
so am I with over 20 years of string-making experience and  plenty of 
mistakes well behind me.

mm : 151.2, 149.5, 147.8, 146.0,  144.3, 142.0, 139.6, 137.3, 134.9, 
132.2, 129.5, 126.7, 124.0, 121.2,  118.3, 115.5, 112.6, 109.7, 106.8, 
103.9
