<HTML>Terry I just remembered I serviced a BB at a church in St. Louis. The piano was used a lot for recitals, and the word on the street was that this was a very difficult piano to tune. I was asked by the new choir director for advice on what to do. First of all, it sounded dead. As a result, piano players were beating the day light out of it to get some volume. This, of course, caused many string to break, and the tuning wouldn't hold. On the advice of Paul Manichino, I replaced the hammers with Renners. Paul admitted that the green monsters were horrible and should never have been put on these pianos. The second recommendation he made for tuning stability was to check the pin block to flange fit. Sure enough, there was a gap big enough to slide a business card very easily all the way from the bass to the treble. I solved that problem by lowering the tension, and inserting maple shims between the block and the flanges. After several tunings the piano was stable, and with the new hammers, it sang. Wim</HTML>
