I have a customer's .410 bore with a hacked up ejector , some idiot
ground the lip off and attempted a repair . The spring is also
missing , but that's a minor issue that can be solved at the local
hardware store . I need to build this up and reshape it , and
planned on using a nickel-based brazing rod - unless someone can
suggest a better alternative . If I were a better TIG weldor ... but
this is a very small piece and my skills are not up to fine work
just yet . O/A is going to be my method of choice this time . Since
the shank portion of this piece is case hardened I'll be wrapping it
in wet paper towels or something and covering that with foil . Snag

How did this repair go? Did you consider machining it from scratch
and then case hardening it as an option?


I ended up building it up with 4 strands of ER70S2 .025 MIG wire twisted
together using my TIG at 35 amps . Worked out very well . I was a bit leery
because I haven't had such great success with low-amp welding in the past .
I did consider making it from scratch , but this is an "heirloom" gun and I
felt using the original part if possible was better in this case .
