I have always use wedges to be sure the action is sitting properly on my bench as I did with this action. I am in the process of adding glides on the front of my regulating bench as in the Baldwin keybed. I will see if I can adjust them to try and duplicate the Steinway keybed. Still working on it.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Al Guecia</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"><B>From:</B> <A title=pianotech@a440piano.net href="mailto:pianotech@a440piano.net">William R.
