Assuming this data  and the ratio you gave is correct, you have like two different pianos :)... the bass is set up with low SW's an a low ratio, and the rest of the piano set up with high SW's and a low ratio.  I would think that would be pretty noticible in both play and sound really. Again, I would definatly even out this situation before getting into any needling. </blockquote> <div dir=ltr><font face="Arial"><font size=-1>I will even out the situation.  But still, evenness was not the problem.  I wonder if evening out the SW will cure my real musical problem of dynamic linearity between P and mF.  Don't think so.</font></font></div> </blockquote> <p>No... it probably wont cure that particular problem. I guess I just like to start off with an even playing field before breaking out the needles. <blockquote TYPE=CITE> <div dir=ltr>  <br><font face="Arial"><font size=-1></font></font> </div> <blockquote dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px">I think it would be best for you to get a reliable measuring device like the Stanwood kit, or make something youself, as it's very important to get dependable data. And it would be fun to get a better sense of how this instrument is set up.</blockquote> <div dir="ltr">That is sure.  I will.  But still, do you think those very numbers tell the whole story ?</div> </blockquote> <div dir="ltr"></div> <div dir="ltr">No.. by all means. The amount of mass, and the balance is of course only one part of the story. And as all other things relative to our work we strive for eveness and consistancy, and it is my opinion that its especially important to provide exactly this evenenss and consistancy in hammer mass and key balancing. A regulation, which we all know must provide as close to "perfect" touch as we can make it will change with the first useage, and change more with the climate and passage of time. We have to time and time again go back and refine our work. But an even basis of weight and balance to begin with provides a more even starting point for touch and voice, and once its installed it stays very stable.</div> <div dir="ltr"></div> <p dir="ltr">I have to scratch my head at some of the very fine technicians I know who are so very very concerned (and rightly so) about the most precise of voicing and regulation proceedures... but simply brush off the value of such eveness in weight and balance.....especially when its so easy to provide, so stable, and (if desired) so very adjustable at the flick of a switch so to speak. <blockquote TYPE=CITE> <blockquote dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px">Cheers <br>RicB</blockquote> <div dir="ltr">Best regards,</div> <p dir="ltr">Stéphane Collin. <br> </blockquote> <p><br>Good luck with your project then !  And let us know how it all comes out. <br>  <p>-- <br>Richard Brekne <br>RPT, N.P.T.F. <br>UiB, Bergen, Norway <br><A HREF="mailto:rbrekne@broadpark.no">mailto:rbrekne@broadpark.no</A> <br><A HREF="http://home.broadpark.no/~rbrekne/ricmain.html">http://home.broadpark.no/~rbrekne/ricmain.html</A> <br> </html>
