Yes, I agree this might be the case, but IMHO it is at least as likely, if not more so, that the tuning pin hole has simply enlarged from pinblock shrinking and swelling and perhaps pin friction over the many years. In that case, the bigger pin should work fine and not affect neighboring pins. > Besides, the CA glue does wonders.

Now the hole has simply enlarged? And what pray-tell is fundamentally wrong with a larger screw as a remedy for a stripped screw hole (as long as the larger screw is large enough to bite into un-chewed-up wood)?
