I\'m sure they could teach a consultant more than the consultant could teach them. I would want to use a pushsstick though on that guillotine.
The wire isn\'t copper colour. I can\'t imagine them paying unnecessarily for plating. It\'s not iron wire is it?

I like the special high reluctance transformer and kindling used as

No Earth.
Joining wires by twisting alone is asking for a fire.

They did solder the connection to the rectifier diode. I thought it
was quite impressive. A lot of thought had gone into the design
and it certainly made good use of recycled materials.

Besides the craft paper substitution, what made you think that
the materials were recycled? Repurposed, maybe.

That is what I was mainly thinking of. The core looked as if it might
have been intended for some other purpose. I suppose the rust and
grime on the laminations are good for reducing eddy currents. It did
seem surprising that the guillotine operator appeared to have all his
fingers. The diode heatsink casting might well have been recycled

I\'m most struck by their work practices. Working on cracked concrete
floor, no tables or chairs. I realize some cultural ethic may be a
factor, but ergonomics & safety are \"universal\". Also, strange that
they have some hand tools, like pliers, but no wire cutters (scissors
is a painful way to cut wire!) or rubber mallet. And they have some
power tools like the drill press and circular saw, but no electric or
pneumatic screw/nut drivers, riveters, etc. And a sheet metal shear.
I wonder if electricity there is a premium? Karachi is the capital city,
but I would think, make electricity as available as possible for
business-sector development. They might do well to host a
manufacturing engineering consultant for a few days.

It looked like cloth covered wire for the transformer. I can\'t imagine
that\'s cheaper than varnish, but maybe there\'s another shop where they
twist it on by hand.
It is the result of poverty.
