You can miss fast & you can miss a lot, but only hits count.
Brass is poison to a weld......so i would braze again with cupro nickel filler rod.....very high strength,and fills a gap rather than requiring close fits.....The casting is very likely ductile(SG) iron....if melted ,the iron is made very brittle,and cannot be restored....Also use a scaling powder as flux,SG iron usually is a lot better with the agessive flux....Incidentally, silver color nickel coins are cupronickel,so you get an idea how hard and tough it is......same alloy,but I cant recommend using a coin as filler ,its illegal to deface a coin.
Well, I decided to have it TIG welded. I took it to the guy who had TIG welded my lathe bed. He warned me that it might have some small pits in it, due to the contamination of the metal. But he did a great job, and I'm very happy with how it turned out.
Here it is:
This is how I received it. He did the grinding and polishing, too.
Thanks to everyone here for their help.

Very nice...that turned out great....now for a few test fires...I love seeing finished work like this. You had the right guy do it for sure.

That looks great! Now get that old Stevens back in action. The birds are waiting....

I would say he did a great job!
Nicely done.
Wow he did a great job.
High nickel content always makes for the best surface to refinish, and it's plenty strong considering where the break is.
I do a lot of silver soldering, and it has limitations, with this fix I think you went the correct direction.
It looks really good!
