I'm working on a ex-player "O" which received has some updates, more like down-dates. I'm unsure what to use to support the cloth on that slope on the plate. Anybody has any suggestions? </FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>By the way....The soundboard crack repair system of Bill Spurlock was a first time for me and with proper set-up of jigs and guides it was a pleasure to use. Very close to the bridge for cracks going under the bridge itself. I still used the hand carved method for in-between bridge and bass apron where the set up would not fit. Real professional looking. </FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>David Chadwick</FONT></DIV> <DIV><FONT face=Arial size=2>Las Vegas, Nevada</FONT></DIV></FONT></BLOCKQUOTE></BODY></HTML>
