High tension? Low? Board stiffness? was Hammer Types

[Alan McCoy]

Thanks for supplying these numbers David. I'm putting them into Pscale so I
can see the graphs and do some experimenting. Would the B be better off with
another bridge or just wrapped strings in the low tenor? If changing wire
size alone doesn't do the trick, it sure makes for a more expensive rebuild!
 
In assessing a scale, do you look at loudness/sustain or hammer contact time
at all?

One of the problems with assessing tension in scales is illustrated by the
data below.  The plain wire sections of the original scales on two pianos
are listed:  Steinway B and Knabe 6'4".  You can see that the range within
each piano is fairly broad.  Ever wonder why you had such a voicing problem
getting the low end of the tenor section to blend well with the bass on a
Steinway B?  On the Knabe you can see that the tensions range from a low of
138 to a high of 209 lbs.  Both of these pianos received a bit of scale
alteration.
