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?

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.
