Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

I’m hoping for some firing pin repair advice, please.

I recently came by a Gew 98 in very good condition, with the exception that the firing pin had been broken off. Visual inspection makes it obvious that it was no in-service failure, rather the pin tip had clearly been grabbed by a pair of pliers and deliberately flexed to the point of fatigue failure. This was done on an otherwise all matching firearm. Of course I have my own self-serving theory as to why this might have been done, but I will leave all that for later.

As problems go, this is not much of a biggie to me, as I have a metal lathe in my garage. Given that, I can think of two alternative approaches to a repair: I can simply drill out a firing pin tip sized hole in the striker body, reverse the drill bit and silver solder it into the hole, thereafter profiling and shortening the drill bit to correct dimensions and conformation.

Alternatively, I happen to have a 3 inch section of unhardened 5/32 inch drill rod blank lying around, I could drill a much bigger hole into the striker, solder that in, and re-profile it to suit. Obviously, the unhardened rod would be much easier to work with as far as shaping is concerned, so I’m confident that I could make the repair look much more seamless that way.

My problem is that I have no idea at all as to what the arsenal requirements for pin hardness might have been, so I do not know which approach might be the most advisable in a mechanical sense. Does anyone have an opinion? Of course, I am absolutely open to hearing any other suggestions. Thank you.

Get with Don, he does firing pin repairs, you can email him a photo and see if he can fix it for you. He'll solder a new piece onto it and shape it to lenght.

Thanks, I thought about looking around for someone to do it for me, but decided that for good or for ill I'd like to try to learn something by doing it myself. But in order to get things kicked off, I wanted to know if it is beneficial or detrimental to use very hard metals in the repair.

Beyond my knowledge base that is for sure, good luck and hope someone gives you the information your seeking.
