Some interesting posts here. I have been interested in setting up for
some brazing with propane but don't want the bother of oxygen tanks
either. Anyone tried compressed air and propane? Is this feasible? It
sounds like a standard oxy/acet torch will do brazing with propane and
oxygen. Is that also true of propane and compressed air?


You can braze small parts with porpane/air and a "swirl-torch" - it has a
gizmo in the torch after the venturi that creates a vortex and makes more
heat.

Noisy, and the propane bottle a) gets cold b) doesn't last very long, but it
works, and the torch is cheap, and you can carry it around in a backpack
with all the orher tools you might need to fix something 8 miles out in the
woods.
I have two of these hooked to bbq tanks with extension hose. They work
great when I need a good quantity of heat. One set cost me about $30
when they first became available, the other cost $2 on a saturday
saleing expedition a couple years ago.
