What size pipe can a standard blowtorch do?
What do you mean by a standard blow torch. (Meaningless term)

What size can a mini torch do?
Another meaningless term

What do you do with joints that fail to seal first time?
Add more flux and solder and reheat.

How would you flare a pipe end with minimal budget?
Not relevant to household plumbing.
Used more on car braking systems.

There is a (sort of) flaring tool sold by BES which is hammered into the
end of a length of 15 mm copper pipe, swageing it out so that it can be
soldered to another length without a coupling.

For fridge pipework, I had a set of swaging(?) tools for increasing the siz
of a pipe's ID to v. slightly more than its OD. Used to put about 1 dia. or
a bit more in, then join it using what I knew as Cuproflow. So long as the
pipe was clean and had been rubbed with a bit of steel wool, it didn,t need
flux.
Used an oxy-propane torch but possibly MAPP would do it.

Flaring is, well, flaring and is used in refrigeration instead of olive - if
you think that forgetting a cable clamp or whatever until after doing the
wiring is bad, try forgetting the back-nut on 1" pipe that's just long
enough! (The T-shirt didn't fit, either).

Copper is used when it is needed.

It isnt ever needed in the third world except in industrial
situations

precisely, it is used.

where the cost of the flux and steel wool to
clean it isnt going to be a consideration.

ha ha

You still haven't said which backward country this sorry saga relates to.

I guess so. ZnCl looks the most likely candidate.

Ah. Bakers fluid. Considerably more expensive than normal plumbers flux.

Why am I not surprised?

It used to be in brake and clutch linings but but like the
epidemic of 'mad cow deaths', only seems to have affected
a few people, who probably have a poor set of genes that
render them more susceptible to aggressive toxins and
contaminents.

When I was about 10 I spent more time on the farm behind
where I lived, than I did at home.

They put up quite a few sheds over a few years and I well
remember standing underneath a corrugated asbestos roof
being installed, where two of the four overlapping sheet
corners were sawn off aloft. The dust rained down like
snow and it was great 'fun' to stand underneath.

I'll be collecting me old age pension in a few months.

Another flux possibility is concentrated phosphoric acid (which also
works very well for soldering stainless steel). This should be readily
available from the nearest soft drink bottling plant.
