Yes, putting a little stress on the keyframe. Actually it would be under a tensioning stress. I heard it first from R.Jolly & David Andersen. Whatever it works.<br>   Dale<br> <br> <br> <br> <div id=AOLMsgPart_2_4f350bee-d690-42df-bdda-a8879bd80f4b> <div align=left>Stressing the keyframe?   <br> <br> David Ilvedson, RPT<br> Pacifica, CA 94044<br> <br> </div> <div style="PADDING-RIGHT: 5px; PADDING-LEFT: 5px; PADDING-BOTTOM: 5px; BORDER-LEFT: #000000 3px solid; PADDING-TOP: 5px">Jon<br>   Nice idea. Easy visual.  My kind of tehnique. Jon You probably of experienced this alreay. Stressing the keyframe a bit more also improves the sound. I've heard it dramtically on many pianos. It has to do with coulping the keyframe more intensely to the bed. <br>  <br>   Dale<br> <br> <br> <div style="FONT-SIZE: 12px; MARGIN: 0px; COLOR: #000; FONT-FAMILY: Tahoma, Verdana, Arial, Sans-Serif; BACKGROUND-COLOR: #fff">Let's try something different, a piano related topic: <br>  <br> An easy way to set the glide bolts is with a caliper. <br>  <br> With the glide bolts off the keybed, measure a key <br> height in front of the bolt. Reset the caliper to .015" <br> to .020" higher and turn the bolt until the key touches <br> the caliper. Plus .010" at the ends is sufficient. <br>  <br> Apply slight upwards lift at the stack to see if the <br> glide bolt still knocks and tweak as needed. <br> This is an easy way to apply even pressure across. <br>  <br> Longer keys would necessitate a wider gap <br> measured with the caliper. <br> --  <br> Regards, <br>  <br> Jon Page <br> </div> <div class=aol_ad_footer id=u8CAAE5446222D90-17F8-6D9B><FONT style="FONT: 10pt ARIAL, SAN-SERIF; COLOR: black"> <HR style="MARGIN-TOP: 10px"> The Famous, the infamous, the lame - in your browser. <A title=http://toolbar.aol.com/tmz/download.html?NCID=aolcmp00050000000014 href="http://toolbar.aol.com/tmz/download.html?NCID=aolcmp00050000000014" target=_blank>Get the TMZ Toolbar Now</A>!</FONT> </div> </div> </div> <div id='u8CAAE7800412E24-820-32A0' class='aol_ad_footer'><FONT style="color: black; font: normal 10pt ARIAL, SAN-SERIF;"><HR style="MARGIN-TOP: 10px">The Famous, the infamous, the lame - in your browser. <A title="http://toolbar.aol.com/tmz/download.html?NCID=aolcmp00050000000014" href="http://toolbar.aol.com/tmz/download.html?NCID=aolcmp00050000000014" target="_blank">Get the TMZ Toolbar Now</A>!</FONT> </div>
