<DIV>OK, so I am learning something here, maybe. I always =
thought I
needed to<BR>support the pinblock because the stress of pounding in =
the
strings might break<BR>something. Consequently, I didn't think =
it was
necessary to position the<BR>support directly under where I was =
pounding;
nearby was good enough. Is<BR>delamination the real threat =
here?
So far I haven't had any problems, but I<BR>want to be sure to *keep* =
it that
way.<BR><BR>Regards, Clyde<BR><BR>John Ross wrote:<BR><BR>> Hi

<DIV>It's a safety measure. You probably wouldn't crack the =
plate or
pinblock, or de-laminate the pinblock, except maybe on an old, =
brittle,
or very dry piano. Delaminating is a possibility if you're =

a real fat pin into a tight hole and it's longer than the original -- =
nothing

the pins
of a string I've just replaced even with the others. But I =

to. (Better safe than sorry). Nearby (within a few inches) =
is
probably good enough, unless they're going in real tight and you're =
pounding
hard. --Dave Nereson, RPT<BR></DIV></BLOCKQUOTE></BODY></HTML>
