Best way is to plug (not dowel) and redrill - or better yet, plug, tap and install a machine screw. I highly recommend plugging with hard maple or a harder wood. The less than perfect way (although it might work just fine) would be to spread some thick CA glue on a few hardwood shims and jam them down in the hole and then spray some accelerator on the screw and sink the screw in.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Terry Farrell</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=jackhouweling@dccnet.com href="mailto:jackhouweling@dccnet.com">Jack Houweling</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A title=pianotech@ptg.org href="mailto:pianotech@ptg.org">Pianotech List</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Saturday, April 21, 2007 7:38 PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Plate bolts/screws</DIV> <DIV><BR></DIV> <DIV><FONT face=Arial size=2>The other day I serviced a Kawai 1996 KU30 and before tuning I checked the plate screws.
