"Spun in".....explain please.

[dewman]

I've heard the expression "spun in" when refering to scale pins and blade hinge pins. Can someone explain exactly what this means and how it's done?

Thanks,

spun in is basically a tool that goes in a press and spins, when it is brought down on to the flat head of the pin it "spins" a head on the end of the pin. They used to peen them by hand in the old days. I peen them by hand, never could get a head spinner to work well.
