[CAUT] reaming prior to oversize pins?

[Dr. Henry Nicolaides]

Hi List,

Once again I request the wisdom of cumulative minds and experience.  Thank you for your comments about my prior questions.  I appreciate your feedback, which to date has saved me time, expense, and most of all help me solve some problems.

My prior experience rebuilding pianos generally was to replace (or shift the pin block as referenced in the new book authored by Carl-Johan Forss) the pin block since most were 50+ years old with evidence of deterioration in some form.  Some "newer" instruments I cleaned the holes as best I could with a wire rifle brush and re-pinned with #3 or #4 pins depending on torque. 

I would speculate the reaming may give a better consistency one pin to another and may also elimanate any scoring caused by older pins.  I have several pianos that the pins "jump" with some that are so tight I have to extend the tuning lever all the way out and others almost move by looking at them.  Keep the block and repin or replace the block?  Budget and time are obviously a concern.  I would prefer to put the time and $'s into one more project...and when discussing these things with our director it certainly has helped to have your opinions.

Thanks and Best Regards,
