340 utility help

I have no doubt that you are correct, and I have repaired some cast parts in that same manner. But an old time North Dakota farmer neighbor proved to me the validity of the brazing method. On my 300U I had broken the left hitch vertical link due to side sway not being adequately controlled. He claimed the brazing of the cast metal (cast steel??) would be as strong as original, and he did it for me. 25 years later and that repair is still good. But I did fabricate a lower sway control to hopefully avoid a future failure. With the cast metal, plenty of heat, lots of flux and controlled cooling after weld, it seems that the brass has flowed in between the crystalline structure and given support to the parent metal alongside of the break. Maybe the Ni rod will do something similar, but I haven't seen it yet. It would be interesting to lab test both methods, but it would take some serious test equipment.
