Strongly agree <G> Always thought of necking 
as somthing done in the back seat of a car or other quiet spot.

Joe:

"Thin spots" are 
  "necking" of the string and lead quickly to breakage since necking happens 
  only when one reaches to or beyond the elastic limit (Young's modulus) of the 
  string. It's why I don't use wire rollers, too! Generally, one has to think in 
  the range of 300 cents overpull to reach breakage (a minor 3rd). In my 
  opinion, there is never any good reason to overpull strings by any more than 
  20-40 cents; even 100 cents is excessive.

Hey Paul,

  
Only credit me with the Elastic 
line.

  
Me thinks it should have been stated ALMOST TO as 
  stretched to the point that the wire thins out in spots.

  
Like in the use of the wire roller. Thin spots on 
  a string will IMHO?result in?false beats on that wire.

Joe (and Wim):

BZZZZT!. "Beyond it's elasticity" means 
    that the string will now break. Overpitching a string will not cause false 
    (real) beats in and of itself unless there is some bridge involvement. And 
    chipping a piano even a half-step high seems to be way more than necessary. 
    I have typically chipped the piano about 25 cents sharp, watched it fall, 
    then chipped it again 10 cents sharp before actually tuning it, with very 
    stable results.

Hi Wim,

    
I suspect there will be a slurry of false 
    beating sounds in the upper range of this instrument, caused by over 
    stretching of the wire beyond it's elasticity.

Who ever restrung this piano really took a 
      chance tuning the piano a whole step sharp.?I chip a piano a half a 
      step high, but even my first tuning is only 25 cents high. I don't think 
      this dealer?understands what is happening to this piano. Is he 
      telling you to keep it a whole step high because he doesn't want to pay 
      you to do more than just a tuning, or does he think customers?won't 
      notice. In my opinion, he is not being honest with him self, much less his 
      customers.

i began to do a 
      floor tuning at a warehouse last week and A4 was tuned as B4. i tuned it 
      to A440. A3 was B3, so i tuned it to A220. about 3 notes later i felt 
      really weird, so i informed the boss what was going on and was told to 
      tune it where it was at. it had just received new strings. 

well 
      that made it easier to tune, but i mean, ive never heard of tuning a piano 
      a whole tone sharp.
