But since it was loose from cracks down below in the first place, the bigger pin will spread the cracks and the neighboring notes will be toast. Besides, the CA glue does wonders. And it's not that the pin is suddenly too small -- it's that the hole got too big. Exactly like stripped screw holes, with the same kind of drawbacks when putting in bigger pieces of metal instead of repairing the hole.
