[pianotech] Consensus of technique

[Paul T Williams]

Last summer in Oberlin, Kent Webb talked a bit about 1098's.  He suggests 
getting the string to pitch and stop.  I tried it here at UNL and it does 
work.  I'm not sure why just 1098's.

It also depends on the age of the piano and the condition of the pin 
block. 
If the torque is very low, the pin is not "twisting" as you tune and in 
addition, if the string is rendering easily, just bringing the string to 
pitch will be the best you can do. If a piano has the conditions I have 
noted, when you go past and try to bring the string into tune, it will go 
flat, past the point you want it to be in tune.

As has been noted, with piano that are "in good shape", and depending on 
how 
high the torque is on the pins, I always go slightly sharp when "settling" 

the pin in and then "tweak" the hammer back and forth to see if the pin is 

"solid" and the pitch will stay where I put it.
