<html><div style='background-color:'><DIV> <P>Dale,</P></DIV> <DIV></DIV> <DIV></DIV> <P>Thanks for your feedback on the let-off topic! I usually use my aforementioned specs for older verts. However, depending on existing keydip, the condition of the back checks, springs, etc, I will let the piano tell me how much closer i can set let-off. In new verts and those that are in good shape, the let off is set closer to your specs; but I still use standard, rather metric measurements.<BR><BR>Terry Peterson </P> <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV> <P> <DIV></DIV> <DIV></DIV> <DIV></DIV> <P></P>----Original Message Follows---- <BR>From: Erwinspiano@aol.com <BR>Reply-To: Pianotech <PIANOTECH@PTG.ORG><BR>To: pianotech@ptg.org <BR>Subject: Re: vertical letoff <BR>Date: Wed, 10 Sep 2003 10:58:09 EDT <BR><BR>In a message dated 9/9/2003 7:48:31 PM Pacific Daylight Time, <BR>pianolover88@hotmail.com writes: <BR><BR>> Terry <BR><BR>I consider that let-off spec too wide.
