I'd say you could do an effective reliable repair using Devcon type putty.
If you love it, lube it.

Why not just braze it? It takes skill though to weld cast iron and not get cracks but it can be done for sure.

Devcon would certainly do the job Jim as it is not a load bearing or pressure area. You can quite easily weld the cast iron with a high Nickel content rod, but it will be much easier to control the application and get a good finish with the Devcon.

brazing will probably last lot longer than epoxy when done right.
