I'm sure an appropriate lawyer could spit something simple out in just a few minutes.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Gotta ask..... why does the owner want a mea-hinge on a pretty piano (except, of course, for the high gloss polyester finish!)?

Music shelf damaged already?</FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black"> </DIV> <DIV><FONT face=Arial size=2>Hello list,</FONT></DIV> <DIV><FONT face=Arial size=2>Have a client that wants the 9"x1" hinge installed on the music rack - it originally never had one " </FONT></DIV> <DIV><FONT face=Arial size=2>The piano has a high gloss polyester finish along with some very fancy veneer on the music shelf.</FONT></DIV> <DIV><FONT face=Arial size=2>Drilling into poly makes me a bit nervous - never did it before, expecially in such a visible area of the piano - </FONT></DIV> <DIV><FONT face=Arial size=2>Is there a technique that someone uses to dimple the spot to drill so that the poly will not split, or to prevent the dirll bit from wandering?
