Hello!
I have 5 of the H&R premier .22 rimfire hammers that all have the firing pins broken off. Has anyone had any experience with welding these back on, and do they hold up very good?
I wouldn't worry about trying to repair them except that original ones in good condition are getting scarce.
Thanks!

The weld is so small two things go wrong. 1 the area your welding overheats and the hardness of the hammer becomes drawn out. Once the new pin is welded in the hammer would have to be rehardened. 2 surface area isnt great so there is little to work with. penetration is key in a good hold but there is little to work with. best case is to cut a slot in the existing hammer and fit a cut firing pin from tooling steel in the slot and either silver solder in place or weld in the rear with a good heat sink,

Thank you for your inputs. I might try to drill and pin one of them and see how it works out.

Not sure about firing pin you describe but the last H&R firing pin I repaired was a flat one made part of the hammer. I just cut the broken firing pin off flat with the face of the hammer, drilled in and put in a round 1/8" diameter firing pin, the nose shaped to do its job. I soldered it in with 3% silver solder. Worked OK but looked different, nobody cared.

I took the five hammers to a machine shop yesterday. I had a 3/32" slot milled into each and a pin hole drilled. I will make firing pins to fit, then use JB weld plus pinning the firing pin in place. I think that will work.

If you properly fit the firing pins, there is no need for epoxy. It will crumble the first few times the gun is fired anyway.

Bill,
You are absolutely correct. I will forget the JB weld. I have to heat treat the firing pin after fitting, and the epoxy would just get in the way.
