I used to cut Granite in Milford, NH, USA. Barretto's Granite. Kittledge Grey. I cut 10-20 ton blocks into strips on a 4 wire saw, that were over a half mile long each. Loved that process. I can you walk thru every step.Well, now everything is clear! The ancient Egyptians had Chinese machines, Chinese cranes, and in general, the ancient Egyptians were Chinese.The stone weighs about 45 tons at most, and if it weighed 70 tons, the wheels would explode and the semi-trailer would fold in half. Don't fool people, to transport 70 tons of stone you need at least a five-axle trailer of special strength!
