<font color='navy' size='2' face='Georgia, Times New Roman, Times, Serif'><font size="2"><font face="Georgia, Times New Roman, Times, Serif"> Hi Joe<br>  </font></font>May<font color="navy" face="Georgia, Times New Roman, Times, Serif" size="2">be your using the  word bearing accidentally to mean crown? If the plate was really floating that much then maybe an increase in tone would occur in the regions which the subsequent plate movement would increase bearing in a 1 to one relationship.  ie mostly at the bass low tenor  or up in high trebles where the bolts are closer to the hitch rail. Even if the  nose bolts/hitch rail  were adjusted  a subsequent amount to match the plate ,...Even then sometimes no change is noticed, except the tuning has now been whacked out.<br>  The beauty of the WN& G perimeter bolts is that it is possible to play with/adjust palte height  after the piano is strung.<br>  More likely what you are hearing is from the benefits of mechanical coupling where energy is now not being lost into gnome land. Either that or....I dunno.<br>  You heard something...good enough!<br> <br> <br> <div style="clear:both"><font size="1"><b><font color="indigo" face="Georgia, Times New Roman, Times, Serif">Dale S.

There is nothing one could do to the rim—or any other part of the skeleton—of an assembled piano that could conceivably cause a resultant increase in soundboard crown. Tightening plate screws and/or bolts simply will not do it—no matter how loose they might have been or how tight they have now become.</span></div> <div class="MsoNormal"><span style="font-size:11.0pt;font-family:"Comic Sans MS";color:navy"> </span></div> <div class="MsoNormal"><span style="font-size:11.0pt;font-family:"Comic Sans MS";color:navy">ddf</span></div> <div class="MsoNormal"><span style="font-size:11.0pt;font-family:"Comic Sans MS";color:navy"> </span></div> <div> <div class="MsoNormal"><span style="font-size:10.0pt;font-family:"Comic Sans MS";color:#632423">Delwin D Fandrich</span><span style="font-size:10.0pt;font-family:"Calibri","sans-serif";color:#632423"></span></div> <div class="MsoNormal"><span style="font-size:10.0pt;font-family:"Comic Sans MS";color:#632423">Piano Design & Fabrication</span><span style="font-size:10.0pt;font-family:"Calibri","sans-serif";color:#632423"></span></div> <div class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri","sans-serif";color:#632423">6939 Foothill Court SW, </span><span style="font-size:10.0pt;font-family:"Comic Sans MS";color:#632423">Olympia, Washington 98512 USA</span></div> <div class="MsoNormal"><span style="font-size:10.0pt;font-family:"Comic Sans MS";color:#632423">Phone  360.515.0119 — Cell  360.388.6525</span><span style="font-size:10.0pt;font-family:"Calibri","sans-serif";color:#632423"></span></div> <div class="MsoNormal"><span style="font-size:10.0pt;font-family:"Comic Sans MS";color:#632423"><a href="mailto:del@fandrichpiano.com"><span style="color:blue">del@fandrichpiano.com </span></a></span><span style="font-size:10.0pt;font-family:"Comic Sans MS";color:#632423">— </span><span style="font-size:10.0pt;font-family:"Comic Sans MS";color:#632423"><a href="mailto:ddfandrich@gmail.com"><span style="color:blue">ddfandrich@gmail.com</span></a></span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:navy"></span></div> </div> <div class="MsoNormal"><span style="font-size:11.0pt;font-family:"Comic Sans MS";color:navy"> </span></div> <div> <div style="border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm"> <div class="MsoNormal" style="margin-left:36.0pt"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif""> <a href="mailto:pianotech-bounces@ptg.org">pianotech-bounces@ptg.org</a> [<a href="mailto:pianotech-bounces@ptg.org?">mailto:pianotech-bounces@ptg.org</a>] <b>On Behalf Of </b>Al Guecia/Allied PianoCraft<br> <b>Sent:</b> Sunday, July 03, 2011 7:27 AM<br> <b>To:</b> <a href="mailto:pianotech@ptg.org">pianotech@ptg.org</a><br> <b>Subject:</b> Re: [pianotech] SnS rim screws</span></div> </div> </div> <div class="MsoNormal" style="margin-left:36.0pt"> </div> <div class="MsoNormal" style="margin-left:36.0pt"><span class="apple-style-span"><u><span style="font-size:9.0pt">Joe Gross wrote: </span></u></span></div> <div> <div class="MsoNormal" style="margin-left:36.0pt"> </div> </div> <div> <div class="MsoNormal" style="margin-left:36.0pt"><span class="apple-style-span"><u><span style="font-size:9.0pt">Cut to the chase: We tightened the bolts  with a socket.
