What's a good way to keep solder from flowing or wetting copper or brass
parts being soldered- sort of like an anti-flux. I recall seeing something
posted here about it, but can't locate it.

Its knowledge, and craft. The knowledge bit is is straightforward

prepare the area to be soldered only
flux it up
use a HOT iron. No ****y electronics ones - at least 100watts, with a
big tip, conical shaped.
get in and out fast. Dont try to tart it up, you will stuff it.

The Craft is:-
Have a practice run first, unless your an idiot. , you will be OK. No
debate, no issues, no preffered brands, its not rocket science, just
an old craft skill.
