I find that using no 1 pins in = new blocks is not a problem unless fit too tight but what pin isn't. I = don't have any trouble with no. ones otherwise. I'll read the article, = really! I can't deny that no 2 are stiffer but ones render nicely when = fit well which is why I like them. >>>>>>>>>>Dale Erwin Dale,=20 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.=20 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.=20 Best regards,=20 Paul=20 ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
