string settling

[Roger Jolly]

Hi Ed,
             On new pianos I pinch the becket, and level the coils so about 
half the becket hole is exposed, never fails,  it drops the pitch a 1/4 
semi tone.Also checking the tuning of the duplex and bring it in line with 
the old strings makes a big difference.

These two things seems to make a huge difference on the pin setting and 
stability,  leads me to believe there is more going on in that pin coil 
than we think.  Jim Bryant gave me the neatest coil setting tool for doing 
this job.  Worth it's weight in gold

Regards Roger
