HEAVE HO | Archaeologist Nicholas Blackwell, left, and his brother-in-law Brandon Synan demonstrate how to use a rope to operate a pendulum saw. They tested the rock-cutting device on a piece of limestone in the Virginia backyard of Blackwell's father, who was instrumental in designing and building the contraption. | N.

Cool! Thanks for posting.
Here’s a really GREAT article about how the huge stones for the pyramids were transported to the building sites. (And no, it wasn’t aliens)

Better have plenty of time on your hands.
The Egyptians said screw it. We’ll just use softer rock.
Good Ole Boys!
Could the Incas also designed such a thing to make their precise cuts in stone?
Very interesting!
Mycenaean civilization have always interested me. Both fascinating and mysterious.
Another thing is all those islands, hundreds of miles from anywhere which were settled before there were supposed to be ocean going vessels.
What type of metal blade. Bronze is too weak to do the job.
Limestone is nothing to cut or chisel away.
Whoa! How awesome is that?
:o]
From the look of the blade, they removed as much bronze as they did limestone.
A silica grit-encrusted cord would make a curved cut, too.
OK, suppose I buy into the swinging pendulum saw to cut hard stone. I have two questions.
1.We have examples worldwide of huge stones, some weighing up to 8000 tons (Yangshee Stele in China) and 800 tons in the Baalbek trio for simple building stones. How were they moved and installed?
2. Why would anyone think that cutting and moving building stones of this size was a good and efficient use?

Neat.
