Did you mill the recess into the inside of the lower tang for the mainspring yet?

What does "forged out the upper and lower tangs" mean? If they broke off I would make sure that action is steel and not malleable iron like a Hopkins and Allen I have and keep dreaming of making a steel receiver for.

All Hepburns are forged steel, not cast iron. Forged steel doesn't mean you can't break it. It simply means it's tougher to break. I've seen numerous rifles with 2 piece stocks that had broken tangs from the owner falling and landing across the receiver, which broke the stock and tang(s).

I have some iron bar from the same era as this receiver. so I forged some of it into the same siz/shape as the tangs. Then tig welded them onto the receiver and trigger bow and filed to the proper shape.

Sounds like a proper fix. The top tang is notably weak due to the large screw-hole for the stock mounting screw, which is also a good place for rust to form. Breaking the lower tang is tougher to do. One of my Hepburns had a very nice receiver, but the trigger guard was almost rusted away. Must have been some sort of galvanic corrosion going on over the years which resulted in same.

thanks SSS, Not really sure what I doing on this since it is something I just decided to do. But I do have a lot of experience and knowledge of metals, welding and heat treating as well as shooting. so just using what I have and doing the best I can and relying on the good knowledgeable folks here to help me out.
