Question about Setting the Pins and Unison Stability

[KeyKat88 at aol.com]

Greetings, 

        Yes. I always pull about 2-3 beats sharper before settleing the pin 
back down, striking the key as I go to keep equalizing. Some tuners 'lift' the 
pin then they turn it, to raise the note. I dont know much about that. 

Good question.

One of the problems I have been trying to solve is how to improve my unisons 
so that they stay in tune longer and don't go out shortly after I have tuned 
the piano. I apply firm test blows to equalize the tension along the string, 
but find that the some of the unisons in the treble still go out of tune within 
a few days or weeks afterwards. I think the problem is due to not setting the 
pin properly. The question I have is, during unison tuning, and when you are 
tuning each outer string to the center string, do you turn the tuning lever to 
raise the pitch to the high side of the center string, to the point that you 
hear a "tinny sound" when the two frequencies are different, and then turn the 
tuning lever to bring the pitch back down so that it sounds pure? I read 
somewhere that the amount the strings should be raised before bringing it down is 
to the point that you can hear a beat of a few Hz, but raising the pitch to the 
point where you hear a tinny sound is more than a few Hz. Thank you for your 
advice.
