Hi Charles, Here in the UK, some of our tool shops stock mouth blown
blow pipes and torches. I spent the first ten years of my working
life in this trade, using mouth blown pipes and natural gas for
soldering. I was trained to use a soldering system that used a bench
mounted Birmingham Sidelight for the gas supply and the flame was
controlled and directed by using a ten inch hooked brass blowpipe. I
have also used mouth blown, hand held gas torches and a gas torch
with the air powered by a small foot bellows. It was only in the
early 1970s that our workshop was modernised with the addition of
electric blowers and Oxy/gas torches.
This is the basic blowpipe for use on any suitable flame or with a
Birmingham Sidelight available from H.S.Walsh tools in the UK, here
is a weblink;
They also sell mouth blown hand held gas torches, here is a weblink;
The attachment shows an old photo of my old master, taken in 1967,
he is shown soldering, at the bench, using a flame from a Birmingham
sidelight and his brass blowpipe.
If you need any more details please feel free to ask me.
