Update: the local welding shop has an aluminum soldering kit and
aluminum brazing flux, but was out of aluminum brazing rod. They had
some zinc-alloy rod that may or may not have worked with the aluminum
brazing flux, in a size way bigger than my job.

So I got the soldering kit.

I'm going to see how well the soldering process works -- if it seems
almost but not quite strong enough then I'll try brazing, if it works a
charm I won't change.

As you have an OA torch it seems to me that if you use a reducing
flame the aluminum will have less of an opportunity to form an oxide
coating and may solder easier. Expert opinion anyone?
