I'm figuring that with nothing
else working it's pretty much futile to try with stick .

No experience... but you might yet try Forney Nomacast rods and
your stick welder. I've got some but never got around to trying to fix
the neighbors broke cast iron piece. They are an odd-ball cast iron
rod and not all that expensive. Wouldn't cost you much to give them a
whirl...

And one last thought, it wouldn't be pretty any more but you could try
scabbing some regular steel to the cast with nickle rods. Maybe shape
the scabs as a U or channel shape and then place over the broken area.
It wouldn't hold up to the heat like cast but might be good enough
(shrug).

The problem is that I can't get anything to stick to this stuff . Won't
puddle under the TIG torch , just sizzles away . Brazing rod won't stick ,
MIG won't stick . Invar 42 (42% nickel) won't wet it . Cast iron strips cut
from an old casting won't stick .
The other project I did for him was a new CI fire pot that arrived broken
.. Used the Invar and got a right purty weld bead . I didn't figure this one
would be that easy , but I sure didn't expect it to be impossible .
