Here in the UK there a lot of plumbers torches, and you have to be
careful about getting the right one for brazing. MAPP gas is OK
apparently, but costs an arm and a leg, so I want to stick to propane.

It appears that propane torches running at about 4 bar get hot enough
without an air supply. Does any one know if this is correct please?
What are the respectable makes? Rothenberger seems to be around a lot.
What about Silverline or Bullfinch??

Any ideas welcome.

If you happen to have or can get ahold of a "buzz box" stick welder, you
could get a carbon arc torch. I've had one for several years for those
"once in a while" brazing jobs larger than I can do with a propane swirl
torch and a few firebricks to keep the heat contained. I never got
around to springing for a full oxy-acetylene rig. You gotta wear a
welder's helmet when using it, but it "do work".

Mine was made by Lincoln (scroll down this page):

I've heard some guys say they made their own cheaply by following plans
like these:
