no 2 are

<P>Part of the problem, even when you read the article, is that it's =
in two
installments, and the February issue isn't out yet. The answer =
to your
question will probably lead to more questions, all of which are =
addressed
fully in the article. The simplest answer, however, is that in a =
Steinway the string height above the pin block - not the plate - is =
roughly
three times greater than it is in an open face design like a =
Bechstein.
Since the string tension is roughly the same, the leverage exerted by =
the
string on the pin is three times as great. If the pin sizes are =
the same
in both cases, pin flex will produce roughly three times as much =
string
movement in the Steinway as in the Bechstein - i.e. it is less =
stable.
Going to a larger, stiffer pin size will partly compensate for that.
<P>Chances are that at this point we get into "but what about...," in =
which
case I get to rewrite the whole article on line. I would just as =
soon
wait for the February Journal. There will probably still be =
plenty to
debate, but at least not the stuff I've already covered in the =
article.
<P>Best regards,
<P>Paul </P></BLOCKQUOTE></BODY></HTML>
