Propane + air silver soldering small parts?

I have a few propane units .. some are large hardware store units that
I use for heating saxophone parts. But I need a small cheap propane
and AIR or that uses AIR not Oxygen (way too expensive $10 for 15
minutes is tooo much) to do silversoldering on small parts. I mean
real silver soldering that is high temperature and results in high
strength attachment as in saxophone parts like keys that I want to
make. There is a type of solder with silver in it but I mean 1200F
melting temp solder that is almost brazing temp.

I'm not sure you can get the heat you
need in a little flame using propane/air.

You probably already know it, but the
nicest way to go would be a Meco torch
set up for propane/oxygen. After the
initial investment, the oxygen costs on
such a little torch would be insignificant.
A small bottle, costing maybe $25 to refill
should last you years.

Oh yes you can. I've been doing it for 35 years!
