I'd vee the tab and TIG braze with silicon bronze or other non-fuming
bronze rod. It's easy to do, requires no pre/post heat, and will put
very little heat into the head.

Or drill a hole in the middle of the tab and plug braze it (can you do
that?).

There's certainly lots of surface area there if you could get something
that'd bond across the whole face where the tab and head mate.


Indeed. The hole in the center is an option, as is high temp silver
solder.


The hole in the center would only attach it to that thin area in the
stud path; much less to hold on to.


But putting a slight grove on the sides and running a tig bead down each
side does sound easy to do.


Couldn't hurt.


Silicon or phosphor bronze?


Yes. (Means: I have no idea.)

Hmm, maybe not. (Their web guy didn't. He linked to the aluminum
repair video, and their brazing rod is ONLY $75 a pound.)
