technicians tout the method of screwing in pins rather than driving them in,
for their upper range grands, supposedly again, at a slow rate so as to not
heat them up. I can’t remember the source of this, but it just
seemed germane to the topic and supports what you said.<o:p></o:p></span></p>

<p class=MsoNormal><span class=apple-tab-span> </span>My
own attitude in this situation is why change pins? I do most of my restringing
at the university using the same pins (removing old strings from them, and
attaching new strings to them, same techniques as replacing an individual
string, but mass produced). I only change to a new, larger sized pin when
torque has become an issue for tuning stability. Reusing existing pins requires
a different technique for restringing, but I find that, all things considered,
it is probably a bit faster than changing pins.<o:p></o:p></p>
<div>
<p class=MsoNormal><span class=apple-tab-span> </span>Just
another perspective. It does prolong the useful life of the pinblock as well.<o:p></o:p></p>
