High Tech production

I love watching these videos where they make stuff in places not as flash as our average garage..

Look at a few particularly ones where they make sand moulds and cast iron gear cogs and the like...but here is an example to start off.

Wow that is incredible Alex, :eyepop: I bet no one OZ would do that, I bet the fella doing this is a bit hard of hearing.:P
No Health and Safety in that place.:lol:

Takahashi Mounts are made using Sand Molds

[xelasnave]

I made my connecting unit between my pier and my mount using a sand mould ( called green sand) and casting it in alluminium.. rather proud of myself but it took two goes...making the male mould took some effort cause you really need to be precise.. I fashioned it in wood.

I had a forge which I connected to a leaf blower and used bbq charcoal from Bunnings..I was going to use cow manure which burns very hot but with my legs being crook even back then was slack and spent money:eyepop::eyepop::eyepop:

Here are some photos I hope

Making tennis balls is a good one, hockey sticks, wheelbarrows, ...and rewinding a motor is unreal.

Also making lead acid batteries..just like this shop floor and the battery looks brand new from auto barn...

I was going to make some batteries but have yet to do so...but by building them I worked out I could save $10 k on a big set for the house...you use lead flashing and epsom salts...but again I was slack and bought some, for my ex and daughter because mainly they did not think my batteries would be any good..AND I just bought some for the observatory about $2,500 I think.. plus solar panels ...again just throwing it around just because I can say I am too crook.;)..

I've spent time amongst the Pathan and Mujahideen in the tribal regions of the
North West Frontier of Pakistan, close to Afghanistan, watching
them make weapons in the world's largest arm's bazaar. They could
make facsimiles of anything - AK 47's, M16's, Glocks, .303's, anti-aircraft
guns and the ammunition to go with them.

Two-thirds of the world's supply of heroin passed through the same
bazaar.

It was fascinating to watch artisans make these weapons in such rustic
settings. Weapons were then tested by firing them outside the workshop
in the streets.

Suffice to say it was a dangerous place.

Tribal law prevailed and these same parts of the country are where the madrassas would form that were the origins of the Taliban.

Hi Alex,

Coincidentally I watched a very interesting battery making/rejuvenation video a while back.....
https://www.youtube.com/watch?v=l665eovBlEk

I love it at around 2:45 when he starts adding molten lead tabs to the electrode plates and then trims them off by chopping them off with a spoon in one swift motion. Skill and experience personified :thumbsup:

Best

Brilliant.
Thanks I really enjoyed watching.

Very good indeed, but look at the pollution, :eyepop: and the lead poisoning possibilities, imaging doing that in a back street of Melbourne.

Leon:thumbsup:

[xelasnave]

Leon you could set up a nice little business fixing up batteries ;) just wear gloves and dump the waste late at night:lol::lol::lol: ...what gets me is it seems they have yet to invent the work bench and a stool...I can not recall seeing a work bench or chair in any of these videos...
Matey may send Lappy tomorrow..at least he has made me such a promise...and I hope so as he is sending me my small knife collection ...which I miss..ornamental but I like them..which is not a crime...yet;).

Thanks Alex, talk to you soon.

More importantly .. where is the QA ... no measurements ... no tolerances :D

Fascinating to watch though ... we know who will survive the post apocalypse.

Regarding workbenches and stools; they require something that is quite scarce in many countries in that part of the world, trees large enough to
make them. Back in the distant past, what trees and bushes there were
were probably used as fuel for their fires. If you researched the subject, you
might find that the peoples from the forested areas of said countries do have
workbenches and stools. Just surmising, no actual knowledge of the subject.

I thought you were somewhat of an expert until you qualified your statements with "just surmising"... But I suspect trees are scarce as I have heard that in some places cow dung is used to fuel cooking fires...I often say to my daughter, because we have 10,000 trees on this place and probably more on the other place, that if we lived in India they would bow to us as we walked down the street..yet trees here are more of a curse because of the cost of clearing to make cow pasture.
If only I could sell each tree for $100 I would be rich... AND looking at videos from China where they gather anything and everything from twigs to huge logs you realise how different things are here... heck when I cleared the land for the observatory there were enough logs for two log cabins but all was just pushed into a heap where it sits until one day when it will just be burnt off.
Nevertheless it would seem there is an opportunity for exciting research into finding explanations for the absence of work benches and stools. And what can we take from the fact that for Australians there is just so much seating and tables...one rarely stops to think in depth about these matters.

Focusers, mounts, clamshells and rings, finder brackets, the older dewshield caps, mounting plates, tripod parts and so on are all sand-cast molded alloy.

It's an aluminium-magnesium alloy they use - a remnant of WW2 aircraft and military paraphernalia production techniques!

Hi Raymo,

Most of the videos posted thus far are from Pakistan. I have travelled
extensively through there and it is true that it is a mostly treeless part of
the world.

There are large deserts in the south-east. Treeless, inhospitable expanses
in the south-west. And the northern mountainous areas of the Karakorums,
which are the western extension of the Himalayas, are also treeless.

Most of these geographical characteristics pre-date civilisation there.

Deforestation, in particular in the foothills, would have removed most of the rest.

And advanced civilisation there goes a long way back.
I have visited the excavated well preserved remains of the Indus
civilisation city of Mohenjo-daro which dates back to 2500 BCE.
They were sophisticated. Waste water was taken from houses by
covered drains. There were public baths. One thing that amazed me
was garbage disposal. Whereas here you have to go to all the trouble
of wheeling out wheely bins, there they had garbage chutes in the
kitchen that went outside to drop the waste into probably a wicker
basket that sat in the recess of the outside wall where the garbage
man then came and picked it up. How good would that be :)

In the on-site museum there is a collection of amazing artefacts.
I remember marvelling over these incredible clay playing die.
Four and a half thousand years old and instantly recognisable, with
just small differences like the layout of the "3" and which numbers were
on opposing sides to each other :-

What I suspect is that since this particular part of the world likely
always had such few trees, sitting on one's haunches has evolved
there into the natural resting position. Though it is common throughout
many parts of the world, I refer to it as the Pakistani squat.

You see it everywhere you go. There will be dudes squatting beside
the road, in front of shops, beside a tractor in a field - everywhere.
Those baggy trousers (shalwar) also make it easier to squat.

Whereas most of us in the west when we go to stand up after squatting
for an extended period have protesting knees, it is such a common
resting stance in Pakistan that I suspect most don't suffer it.

The average income is very low so possessions like tables and
chairs are out of reach of many. If you are invited to eat in some
households you sit cross-legged on mats in front of a shared dish
eating with only your right hand as is the custom.

In public eating places though, tables and chairs are the norm.

Watching artisans fashioning things like gun stocks it was not uncommon
to see them hold the work piece at times between their bare feet.

I suspect that for many there, since tables and chairs have not been
a major part of the culture for thousands of years, they have grown
comfortable either squatting or sitting on the ground.

Traces of the British Raj are everywhere. To go from the extreme of
chairless, I found myself in a solid beautifully carved chair in the First
Class Waiting Room for Gentleman at Lahore railway station. The chair
had a place where British officers could park their swagger sticks.

I like this one...I expect in "the West" these would not get a second life.
