The relationship between the bit size and pin size will vary = depending on the type of block and the drilling methods. Do a search in the archives = and you will find all sorts of suggestions for where to start. Start = conservative (use a bit that might be on the small side) and drill. Try the 3/0 pins first. = Start at A0, drill the hole and pound the pin. Test the feel before you go any = further (and maybe, just in case you are way off in fit, try turning the pin = after you pound it in half way - if it is too tight at that point, just turn the = darn thing out and drill out the hole with a bigger bit). Adjust as = necessary. You can patch up the first few with the 0.288 if need be, and you will = likely have a good combination for fit within the first few pins. Remember to use good = support underneath and mic the pins first.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>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=tomtuner@comcast.net = href="mailto:tomtuner@comcast.net">Tom Driscoll</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A = title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech@ptg.org</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Tuesday, January 20, 2004 = 1:01 AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> tapered tuning = pins</DIV> <DIV><BR></DIV> <DIV class=Section1> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">List,</SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: = Arial">           = I’m replacing bass strings on an older   5’10” Henry F = Miller grand.
