Cheap welding

Dear Leon,

Gasoline 'burners' have been around since the late 1800. I think they
need pure oxygen to generate a flame that is SMALL ENOUGH for a task
as intricate as welding thin-wall, small diameter steel tubing.
Unfortunately, the gas generator has a habit of exploding as the
volume of gasoline falls and the amount of the tar-like residues
increases. I don't know why this is so, I'm going on information
heard when I was a kid. That is: gasoline 'burners' are bad whereas
oxy/acetylene are good.

Personally, if I were stuck in a Third World Country and had only a
gasoline burner to weld with, I'd probably try it... but there are a
lot of other methods I'd try first.

Well, I have even less than no experience, but it looks like oxigen could
easily be introduced along with the fuel--especially as the fuel supply
nears exhaustion--and that is a VERY bad thing.

I have not even viewed the links, however I would
suspect that -

The absolute last thing in aviation that anyone should
consider doing in a way that deviates from established
practise is welding an airframe.

While welding might appear simple and obvious I have
the idea that this appearance is not the whole and
complete truth. There is a *lot* of chemistry and
metalurgy in the act of welding. The cost of a few
cylinders of welding gas is an insignificant element in
the cost of producing a metal aeroplane. If you can't
afford it use wood.
