<div> David:<br> <font face="Arial, Helvetica, sans-serif"><br> I've always been charmed by the phrase "key travel" since it so wholly consumes the movement of the action, with the two major components of jack travel to and through escapement, then the necessary residuum of aftertouch. Key "dip" has been, I think, a major stumbling block in understanding the importance of the total key travel at the front end. Aftertouch, as a component and resultant of regulation, becomes so apparent!<br> <br> Paul<br> </font></div> <div> <br> </div> <div> <br> </div> -----Original Message-----<br> From: David Andersen <david@davidandersenpianos.com><br> To: pianotuner@embarqmail.com; Pianotech List <pianotech@ptg.org><br> Sent: Wed, 30 Jan 2008 4:54 pm<br> Subject: Re: Korean Dip<br> <br> <div id="AOLMsgPart_2_b1550c24-108e-4b08-9ea8-03539bad584c"> Mr. Barnard--- <div>Just take it to the bank---really---that most if not all modern acoustic grand pianos operate on a minimum key travel of 10mm.
