A string's treatment/ Isaac

[Joseph Garrett]

Isaac,
You said: "BTW, Joe, we checked the scaling of a little grand Shimmel, with
55 mm
at c8 and 93% of breaking strain (at 442 pitch) this is  not really a
low tension scale, other octaves give us values between 75 and 85%
breaking strain. where do that appreciation comes from ? (other models
may be ?)"
First: What the heck is with the "442"? Second: I don't know what kind of
scale program you are using, in relation to formulae, but the numbers you
posted, IF they were correct, (which I believe they are NOT.), would be a
disaster waiting, (a short time), to happen. The common rule that I was
taught, (by Del), was not to exceed 55% - 60% of the breaking strength,
EVER!,unless it is impossible to avoid!!  Any scale that I have done on
Schimmels have always been in the low 170's, (plain wire), which is, by
todays scaling standards, a low tension scale. Most of these were 5'6" or
larger, however. So, if you are checking a Short PSO MADE by Schimmel, then
all bets are off. Most PSO, ie small, ie "infantile" grands are scaled off
the map, with the idea that they need to SCREAM, in order to be any good!
<G> Stupid thinking, as most "infantile" grands are used in small rooms that
don't need "power", IMO. However, even that is stupid, as higher tension
scales do not necessarily create "power". (Just bad sound and Harmonic
imbalance, IMO.)
On the original subject: having read you further postings, I have come to
the conclusion that someone is yanking your leg....OR is just plain full of
it. In order to do what you say is needed on these "new" strings, you would
have to, first, do a complete scale evaluation of the piano. Then you would
have to calculate for each note what the "elastic" point, that you are
aiming at, is. Then you would have to tune the piano with this information
as a criteria, which would sound like so much crap. AND you'd have to
convince the client that this is what the client has to endure to establish
a "great/stable" sound. Humph! All tripe, (or other organic substances),
IMO!!!!
