Old but amazing casting for car alloy wheels

 We all thought that beautiful mag wheels are only built by modern machinery and casting technology .  But here we can see that sand casting produce alloy wheels cheaply and also beautifully.  Lot of grinding and polishing to do of course.   But it can be done

The inputs are scrap aluminum from engine blocks and other scrap aluminum parts/junk

Beatufiful.  Amazing

Emergency Front axle repair

 One of the most annoying thing for truckers is to have breakdown and you need to repair the truck immediately, lest you do not get paid.  If you have perishable goods, the goods for delivery might rot and decompose.  

The alternative to this is to buy brand new trucks (which the people here can not afford)  build your own repair facilties: with parts inventory, technicians, machine shop.

Here we can see that numerous technicians and machine shop make emergency repairs possible...

Let us see how quickly and how cheaply were they able to complete the repair

Here we have to tow the truck and buy the parts.  Perhaps, they cant afford to do that.  They have to make do with the resource they have:   resourceful technicians and craftsman and machine shops (they build their own lathe machines).    How useful they are to their economy  and society at large.
