Solid Plunger Firing Pins

[Austin W Hogan]

I soaked the firing pins in Ballistol for about an hour, wiped them clean and made a micro photo at .001 inch resolution in back satter, and .0005 inch resolution in forward scatter.

The dark field photo shows the smooth radius at the butt end of the pin. There is a radiused recess in the anvil .032 deep. It is also possible to see a short straight section intersecting the taper of the pin.

Also note the nickle plate on the undamaged anvil.

I am not sure that the web compression will retain this resolution.

This is a technique I am working to examine the appearance of a trout fly from beneath, lookin toward the sun, as a fish might see it.

Best, Austin
