Out looking for pins to finish up a resto job. I got some 16 gauge brass wire since it was 0.062992" and a 1/16" pin is 0.0625" so they should be about the same.

I got home and clearly neither is going to fit properly...there's a bit of gap between the pin and the hole in the blade and scales. So here's the question: Does the pin expand internally while it is being peined or is this a freak that does not take a standard 1/16" or 16g pin?
