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

[Jim Busby]

Hi Daniel,

 

We already have data on breaking strength, tensile strength, sheering
strength, etc. but could you give me a question I could pose for
malleability and fracture time with working? Sounds good, but I'm not
sure how to word it. Stainless (Pure Sound) is MUCH more malleable, but
how can we measure it or quantify it, and what would that mean for the
technician? Just searching for a good Q. Also, when using stainless you
need to handle it a bit differently. You can't "force" it around the
hitch to make your beckets line up. I guess that's what you're asking?

 

Thanks,

 

Jim Busby BYU

Good going and wishing well the project.

 

Compare breaking strength.

Compare malleability.

Compare fracture time with working.

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,

Jim Busby BYU
