or is anyone going to?</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=335170608-31102008> Its always
interesting to know the cause of a crack?</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=335170608-31102008>Perhaps the origin of the
crack will be apparent when it is opened prior to welding.</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=335170608-31102008>Spotting origin is not
necessarily going to show the cause.</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=335170608-31102008>All castings have small
flaws and any crack will start at a point of stress.</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=335170608-31102008>the cause could be the
flaw, or the metallurgy, or excess loading.</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=335170608-31102008>excess loading is
difficult. A warn and well bedded clapper may be o/k but move it slightly, say
for example to correct an odd struck bell, can result in the impact point moving
to the edge of the kiss mark, locally raising stress considerably until it beds
back in.</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=335170608-31102008>I believe, for example
the failure of the old tenor at Watton at Stone occurred because the leather
wore away, allowing the clapper to strike to far out on the sound bow, impacting
the outer edge of deep and badly warn kiss mark.</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=335170608-31102008>I repaired the leather
twice on that bell and left warnings about keeping an eye on it the crown
staple loop was badly warn on the inside and the leather needed extra packing to
hold it up in the correct position.</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=335170608-31102008>the large flat on the
inside of the loop wore the leather badly so it needed regular
attention.</SPAN><SPAN class=335170608-31102008></SPAN></DIV>
