Winchester 1894 firing pin length

[Airmad]

Hi guys. I have a Winchester 1894 (made 1896] in 38/55.
The tip has broken off of the firing pin.
I want to replace the tip. Does anyone have one that you can measure the overall length of the firing pin so I can match it? Thanks.

I read in a book I have that the 1 piece pin is 3 19/32" long.
They also talk about different types ????? Hope this helps?

You can also measure the length of your bolt (extractor removed and add ~.05"

Match your other dimensions, make the pin section long, and trim it back to correct length once you get to that stage.

One here measures 3.6175" by my digital calipers. Max extension of the pin past the inner bolt face is .069", probably intended at 70 thou max.

That’s great guys.
Thank you.

Repaired a Marlin 1894 firing pin with a broken tip. Not too dissimilar to a M94 Winchester's.
Set it up in the lathe, flattened the broken end, drilled a hole. Silver brazed in the shank of a drill bit of appropriate diameter. Cut it to length, radiused the tip. Worked fine.

Exactly what I’m doing. Great minds. Thanks.

Yeah, not a tough project to build entire, but if you don't gotta...

When you silver solder the new pin in place, plonk it direct in the water to harden from the same heat that melted the solder. Polish the pin clean and shiny.

Stick it in the oven at 375-400 for an hour or so to draw the temper a wee bit down from full hard. Should be a pale yellow color or pretty close. Maybe a wee bit higher than 400 degrees, but the normal temp swings of an oven will likely cover that.



From https://en.wikipedia.org/wiki/Tempering_(metallurgy)

Providing you are using a simple carbon steel for the pin. Other materials will take a little research as to what will work best to not end up with a pin that breaks like glass.
