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

[Jim Busby]

Wim,

 

What a great idea! I wasn't even thinking about that, but indeed that is
THE major difference, after all. Hey, I'm sure you'll need some
stainless in your new job... 

 

Thanks.

 

Regards,

Jim

	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,

	Jim Busby BYU

We all know what rust can do to strings. But how does that effect the
tone of the string? What I would to see is some micro photos of strings
with rust, the oxidation process, and the difference in tone between a
rusted string and non-rusted string.
