These are the men who built Pyramids of Egypt. Still using the same tools.I love these guys. ))) They welded everything, milled it. Washed it... Then they stuffed it all back into the sand and with the sand. I'm not even talking about the time spent. But after a week of this thing working, the guys will have work again and everything will start all over again.Hats off to all of the men involved, if ever there was a film to show people about not giving up, no matter how much effort you need to put in to complete a task, this is it.
