<DIV><FONT face=Arial size=2>Good hypothesis that something may have been
binding under the pressure bar. When raising pitch, the section by the tuning
pin will be under greater tension than the speaking length. There will always be
some friction under the pressure bar.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also consider that different manufacturers' wires
will have somewhat different breaking tensions. I can't think of any reason not
to go up to a .040 leader in this case. (Larger diameter will be stronger.)

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The technique of splicing a wound string at the top
of the winding, in the speaking length, works remarkably well, and would give
you a few more chances.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>When the original core wire breaks in the splice,
there's probably no solution but replacing the string.</FONT></DIV>

<DIV><FONT face=Arial size=2>Should you charge? I'll leave that to better
business minds than mine.</FONT></DIV>

<DIV><FONT face=Arial size=2>I wonder if something in your splice technique

<DIV><BR></DIV>Ed,

<DIV>The first time, I used a larger diameter leader. The second time, I used
the same size as the original core.</DIV>
<DIV><BR></DIV>
<DIV>I don't think anything that I did would have made a ding in the wire --
at least not where it broke. The splice was in between the pressure bar and
the tuning pin.</DIV>
<DIV><BR></DIV>
<DIV>And regarding your subsequent e-mail, it was the leader wire that broke
each time. The original wire and splice loop were obviously fine, since
neither broke. :-) Usually, it's the other way around when I do it --
the original wire breaks, and the leader wire is fine.</DIV>
<DIV><BR></DIV>
<DIV>You could see small indentions in the V-bar, but it looked normal. So I
don't think the string was impeded by anything that might cause it to break
under tension. (I couldn't feel the back side of the pressure bar.)<BR
