[CAUT] existing pinblock prep

[David Ilvedson]

I agree completely and do the same...I'm also wondering if the torque is fine and you are restringing why do we necessarily have to go up a pin size?

 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. 

 Just another perspective. It does prolong the useful life of the pinblock as well.
