As the firing pins for Toz35 seem to get rare... why not copy them? The shape is not difficult.

But what kind of material should be used? What would the caracteristiques have to be?
And is there a post treatment needed?

Any metalurgic specialists?

If I was going to make a Toz firing pin, I would use O1 grade tool steel .

After it was completely machined, I would flame harden it by heating till red then quenching in oil. Then polish the black scale off and temper it back (also with a flame). When tempering, I would work the flame around the top and tip of the firing pin to run a purple colour over most of it but leaving only the "sear" a dark straw colour.

The reason I would do it like that is to leave the "sear" harder then the rest of it. The body and tip don't really need to be that hard, but where the sear engages should be quite hard. Allowing the body of it to temper back more should reduce the chances of breakage.

But that's just how I would do it, I'm sure there's other suitable steels and methods.

When I first researched about this gun, I found many posts about the firing pin, and later I read that most of the time the firing pin is not the problem, but the spring that actions it.
You should rest your gun with the spring released, and others have explained how to do so without damaging the firing pin, and as a way to practice dry fire. I forget to do it all the time.

Larry Carter in Maine is making them. I have one he made it looks quite good. Greg
