<p align="left">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/><br/><br/></p>
<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><!-- end of AOLMsgPart_1_069b3726-77ac-4687-ba4b-5b16131e5750 -->
