[CAUT] Scientific study - Stainless wire (Help!)

[Bdshull at aol.com]

Jim,
 
I'm interested in a study which goes as far as possible to understand the  
wire from the 1850s to the 1880s, which is the main target intended for  
replacement by Pure Sound wire.  
 
Ed Swenson's studies are a good start (I've referred to his extraordinary  
website for a long time), and we need much, much more.  
 
I can only say that the pianos I saw and played at Chris Maene's store in  
Belgium last May which were restrung with Pure Sound (especially an 1890s Erard  
and an 1870s Steinway) were astounding.

Hi  Jurgen, 
You’re right. I can’t  see why Americans don’t use it, except that they haven
’t used it. I “went out  on a limb” and experimented with it on one piano. 
Now after about 3 years I’ll  use it EVERY time I can! 
I think the tuning  stability has to do with the malleability that Daniel 
mentioned. It’s  absolutely amazing to me that it takes only two or three tunings 
on a newly  strung piano and it’s stable, ready to play without any “prepping
” (bending,  etc.) Besides the stainless factor I think this is the biggest 
reason why I  use it. Instant stability. Good question. Thanks.

Hello Jim, 
 
this sounds like a very worthwhile, interesting, and  for me, exciting 
prospect. 
 
As a believer in stainless wire for many different  situations and 
applications, I am surprised it is so slow to get recognition  in North America.  
 
Among the things you mention, I wonder if there is any  way to study how and 
why stainless wire attains such a high degree of tuning  stability.

List,  
 

 
We (BYU) finally are ready to do  some scientific studies of stainless wire. 
This will be conducted by Physics  professors/students here at BYU. Could any 
of you help me pose some  “questions”, “queries” or whatever you want to 
call it, for these  studies? 
 

 
One of our student piano  technicians is doing his senior project and his 
professors (who we’ve bugged  for years) are just now getting excited about this. 
 
 

 
Here are some things I’ve  thought of; 
 

 
1 What are the actual differences in sound between  stainless and Mapes or 
Roslau? (Spectrum, etc.)  
 
2 What are the differences in inharmonicity between  the two? 
 
3 (how?) Do bass strings with stainless core sound  different than other 
core? 
 
4 etc…. 
 

 
Jim Ellis, others, I’d really  like some input on this. We have our ducks in 
a row so now is the  time. 
 

 
Thanks,
