<div>That's hard to believe? Unless they were actually turning in one turn at time and coming back later for another turn, the heat has got to be significantly more than driving. Driving in a little and coming back to drive more would be much more efficient, imho...but what do I know. Is this an urban legend?</div>

I can’t remember the source of this, but it just seemed germane to the topic and supports what you said.</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.</p>

<p class="MsoNormal"><span class="apple-tab-span"> </span>Just another perspective. It does prolong the useful life of the pinblock as well.</p>
