<html> <body> Del, I've made myself a note to check that.  My impression is that the strings are at least 6mm probably more above the plate. Sincerely, Andrew At 10:48 AM 8/22/2005, you wrote: <blockquote type=cite class=cite cite=""> How high do the strings ride on the hitches?   One problem with this system is ease with which downbearing can be set following plate setting. Workers tend to get careless knowing downbearing can all be taken care of later on after stringing. If this -- the plate setting -- is not done properly, and the strings ride much more than 5 or 6 mm above the plate surface, there can be quite a lot of torsional stress on the plate. Hence, more plate flexing during a pitch raise.   Ultimately, the system will stabilize but it might take an extra tuning to get there.   Del <dl><hr> <dd>From: pianotech-bounces@ptg.org [<a href="mailto:pianotech-bounces@ptg.org" eudora="autourl"> mailto:pianotech-bounces@ptg.org</a>] On Behalf Of Andrew and Rebeca Anderson <dd>Sent: August 19, 2005 2:31 PM <dd>To: Pianotech <dd>Subject: Re: Accu-just hitch pins and tuning stability <dd>Ron, <dd>How long since the last tuning that it was 60 cents flat? <tt>The owner didn't know. </tt> <dd>More likely, it was strings rendering through the bridge over time after you had done the pitch raise and left the building. <dd><tt>Yeah, but I work on other pianos that don't behave the same way.  Vladan may have something on the pin-block fitting issue.  <dd>It did tune up solid while I was there and going over a second time everything was still within 1/2 cent with a 5cent correction in one pass.  I'll look closely.  I've just noticed the same thing on a number of Baldwin grands and am looking for common denominators. <dd>Andrew </dl></blockquote></body> </html>
