I have been slowly retrofitting an old Westerfield thotgun, and in the
process I put to much strain on the trigger pivot pin and broke into 3
pieces. It looks like brass to me. The raw surfaces are very shiny like
brass, and have no hint of the pastiness I sometimes see in bronze. It
measures at about .090 as near as I can measure a twisted broken pin part
about an 1/8 inch long. I can't find any bronze that small, and the
nearest
brass piece I can find from McMaster is 3/32 (0.09375). It looks like the
only answer I am going to have is to polish down a piece of 3/32 brass
rod.
The trigger is a pretty integral part of this mechanism with a simple hook
that holds back the firing pin when you close the bolt, so I am trying to
decide which alloy is going to give the best life for this application.
The
gun is over 60 years old, so whatever the original pin was it did a pretty
good job.


How bout using a piece of brazing rod? And yes..it may have been
brass. Its a very low stress part. Id personally use bronze or even
Stainless steel and then pass the arm down to my great great grand
children.

I looked on the shelf and I had both 0.090 carbon spring wire and stainless
spring wire. The stainless said, 0.093 on the tube, but when I measured it
I got 0.090-0.091. A short piece of stainless works just perfect. Well
longer than the original piece so its easier to work with. I may go out and
shoot it tomorrow. This is not the first thing I've had to fix on this gun.
It seems like every time I fixed something, something else broke. I've got
a complete spare bolt assembly on the way now just in case. LOL.
