tight pins

[Leslie Bartlett]

Another point.......  The guy who went back to the sledge hammer from the
nailer also said that he experience that kind of movement caused the
wood/glue in the block to sieze the pin, and has had them break off.  Worth,
then, turning slowly maybe to prevent heat buildup...

Hello List,
 
I recently had real problems with a piano which had recently been re-strung
and the pins were  ridiculously tight.  It was the type of rigid tightness
which makes tuning stability  impossible because of the amount of twisting
in the pin.   I initially had RicB's idea of winding the pins out and in
again with the becket out of the hole.  
What I found to be totally effective was winding each pin out ONE full turn
and back again, 5 times. This does not loosen the coils enough to cause the
becket to come out.  OK, you have to tidy up the coils and make sure the
beckets are nipped in, but you don't have the fiddle of putting beckets back
in the holes.  The heat which builds up in the pin appears to be just enough
to expand the pin in the plank in order to give it slightly looser fit.  The
result has been fine, and I can now acheive a totally stable tuning .
