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... les b _____ From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of Byeway222 at aol.com Sent: Sunday, January 13, 2008 7:12 AM To: pianotech at ptg.org Subject: Re: tight pins 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 . ric No virus found in this incoming message. Checked by AVG Free Edition.
