hi /diy/, i get an old handheld blowtorch used for brazin a/c pipes, but is quite old and dysfunctional. principally cos the gas mixer was too oxidized etc...
the thing is, im planning to make a new mixer with a piece of cupronickel. but there are several of differents flameshapes i guess for difents uses like cooking, brazing, or just heating. and i dont know whats the best for melting things a large one or someone like the pic.
anyway why no blowtorch tread?

that's the mixer. the center hole its outsized and the others dwarfed cos oxide
You could check out lp/air torch heads like the classic turbotorch for inspiration. They are plentiful on Ebay but torches are interesting to play with. I rebuild torches to use and as a hobby.

There is a wonderful book about gas welding which also has lots of theory applicable to your interest.
You want a 1930s edition like this example from when OA was king:

I understand you have an LP torch at the moment, but this stuff is well worth knowing for DIY.
You can find lots of useful books on https://archive.org/index.php for free download.
Spend some time there.
