[CAUT] Wire Stretch/ Stainless

[Jim Busby]

Not yet David. This summer we hope to do it along with a spectrum study.
We have 5 Ms, a B, a 1098, and a Baldwin L. We hope to do several
recordings to compare.

 

Regards,

Jim

Is there a sound recording of the wire in a modern piano?

No. It has a tendency to break (2%) more during restringing and requires
a gentler handling. You can't muscle it around the hitch pin to make the
beckets point the same direction. This is also why Juan Mas Cabre
meticulously buffs friction points. After stringing it seems the same as
far as breakage goes. I only have 3 years experience with it, but it
seems great so far.

Is this wire less breaky?  -blt

	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...

	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.
	Regards,
