Is your method, using a soft faced hammer intended to tap the top = of the check itself or just the wire?</FONT></DIV> <DIV><FONT size=2>How do some of you others approach = this?</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>The other issue of check height relates to a = re-designed action, lowered hammer centre height etc etc, so the old check height = may not be the best position, though could be a close guide. Sorry I didn't mention = this before. (Pity, you could've stayed a bit longer in NZ to solve this one too)</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>My thinking is that for the most efficient checking, = the best situation is to have the most hammer tail surface area in = contact.</FONT></DIV> <DIV><FONT size=2>Therefore, if the ideal checking distance is say, 16 = mm from the string then the top of the check could be set so tat the hammer tail = is well down the check leather.</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>Does this make sense?</FONT></DIV> <DIV><FONT size=2>Any other thoughts on this, any rules of thumb (or = rule of thumbs) here?</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>Regards</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>Graeme Harvey</FONT></DIV> <DIV><FONT size=2>New Plymouth </FONT></DIV> <DIV><FONT size=2>New Zealand</FONT></DIV> <DIV><FONT size=2><BR><BR> </FONT></DIV></BODY></HTML>
