[pianotech] Oversized tuning pins

[David Love]

It can also happen if the new oversized pin bottoms out where the original
pin stopped.  That area below the original pin is still the diameter
designed for the original pin so when the new oversized pin gets down there
it's too tight and worse, it's too tight at the bottom of the pin.

Scott,

Yes, that's one of the possible causes, but there are others.
Removing the old pins and creating to much heat (burning the hole). New 
tuning pins to large. And I'm sure there are hacks out there that can screw 
it up in other ways.
