[CAUT] Wire Stretch/ Stainless

[Vincent Earl Mrykalo]

Prepping shouldn't be done at all on puresound except to seat it carefully at the hitch pins.  It literally straightens itself out around the bends, which I think is one of the big reasons it becomes stable much more quickly than regular stronger wire does.

List,

I'm no expert on wire but since I've used Pure Sound Wire I think I
should at least mention that this stainless wire is almost immediately
stable w/o any "prepping". I know it must be hard to believe... You
string a piano, chip it up to pitch, fine tune it, then place it in a
practice room and it acts like you did the stringing a year ago! Plus it
never rusts and has less inharmonicity. Only a slightly different sound.

I'm not sure what ramifications this has concerning "wire stretching"
etc. but I'll let you more scientifically minded techs tell me if it
does. Seems to be a BIG thing to me, but what do I know...

Regards,
Jim Busby BYU

Hi Ron,

Back in the bad old days when I was doing what Roger Jolly recommended
(i.e. seating strings with a small hammer and using a hammer shank as a
"drift") I never came across a string that went up in pitch. Some
strings
would not change pitch, and even in a single unison there were
differences
of zero to 35 cents among the three strings. I took a lot of
measurements
because I was hoping to create a "guesstimate" of how much to go beyond
A440, seat the strings, and end up near A440.

I think coils may squirm for many years. Certainly when I tighten them
stability is improved. Too bad we don't live longer--so we could see the
results of our (performed in good faith) actions 20 years later. Again
with
coils some strings seemingly don't change pitch even when they clearly
have
moved to tighter coils--and others may drop up to 150 cents.
