A set of left hand thread drill bits from maybe 5/32 = on down. Some diamond burrs for making a starting dimple. A fine center punch, = some lube, WD 40 or such. ez outs and other extractor types in various sizes, = agraffes and their tools. Drill motor. Dremmell tool. That's probably enough to = start. Just having the kit will give you an idea of how to proceed. It may well come = out when you drill it. Flatten the top first with a grinder on the dremmel, = then make a dimple dead center with a cone shaped, then center punch, lube, = then drill for your extractor. IMHO I would not worry about over torque. Turn = down till tight, then the relief in the shoulder should will crush as = you line up the new aggraffe. This will properly seat the new part.</FONT></DIV> <DIV><FONT face=Arial size=2>Fenton Murray, RPT</FONT></DIV> <DIV><FONT face=Arial size=2><A href="http://www.MurraysPianoTuning.com">www.MurraysPianoTuning.com</A>= </FONT></DIV></BODY></HTML>
