They got the Veritasium guy in the documentary.

i dont like the fact that they call core 7 impossible because after 5 minutes of drilling with tools they weren't getting anywhere. that's because the Egyptians didn't get bored after five minutes,.

I have a sold Alabaster Crystal Chimney Topper, that absolutely passes all the tests for having been done in Ancient times.... Six flute drills, vibrational softening techniques..., a drill bit 5 inches in diameter was used in my chimney of crystal to drill 2 mm per rotation through .14inches of crystal without a chip.I was given the chimney for doing some work, and funding a project. Thank you Mam. The grooves in your core look identical to my chimney, only at 5" diameter and at a 14" depth.. WOW

For years I have used copper pipe to holesaw glass with the aid of diamond lapping compound. The diamond embeds itself into the softer material, the copper, and it then grinds it's way through the harder material. It's like using a pitch lap to grind lenses or mirrors for telescopes.

First wrong turn is using the term ‘Egyptians’ in reference to any of that construction. Acknowledge that, and it brings you one step closer

Coating of diamond attached / glued to the copper would cut a Core 7. Water power from canals could power uni-directional drill.

I have no imagination and I get bored quickly. IT CAN'T BE DONE!

The most astonishing thing to me is how little the writers of this show think about ancient humans.

Wow..... They figured out a hole saw and a grit slurry to cut granite. We have nothing like that today! Im impressed

If it was a mechanical drill making core 7, the spirals would be more regular. Just looking at the spirals shows that multiple people worked on the core. You had 3 guys get nearly half an inch into the granite. So if you had 10 groups of 3 guys switching out every 5 minutes or so, you could easily get a granite core in a day.

I see someone's been watching UnchartedX videos in their spare time! It's great to see this topic move into the mainstream.

Let's also remember they didn't think of time like we do❤

As for the core drill. The reason for the smaller size at the beginning of the core and becoming larger at the bottom was the bit they used was walking around until it got deep enough to stabilize itself. Ive core drilled thousands of holes in concrete and granite. If the machine isnt secure it allows the bit to walk a little bit and the cores look exactly like this. However even with a diamond bit it takes FOREVER to core a 3" hole 4" deep. You have to have a cocretter block to chase the bit after about every 1/4". I can only imagine how long that 1 hole took back then. Hopefully it was done BEFORE the header was placed.

The Egyptians used a copper tube on a pole with a weighted stone on top and a hand crank spindle. There are wall paintings of this tool as well. When spun by hand they added water and sand. There is a video of scientist making this type of rotating hand drill and could drill a 4" in about 6 hours. As the copper drill was use it got sharper. The grooves were caused by sand imbedded in the sharpened copper. Additionally, with these hand tools also created the core taper from the wobble. There is another video of artists making stone bowls with primitive stone tools. Seek them out, it is no real mystery. K.I.S.S.

Add a simple wooden frame around the bit and either a hand crank or a treadle, and you get muscle-powered, one-directional grinding that would leave the irregular distances between the lines. Maybe even a flywheel if you don't want it to stop when changing the laborer powering it. A bit of wobble, with the surface as the pivot point, and the slightly conic shape is produced. Really, the single biggest thing that the ancients had that we've lost is patience. "With a modern tool, it takes 5-6 minutes to cut a 6-inch core" - said as if 5-6 minutes was a ridiculously long time.

The fact that ppl believe dudes were just walking around with a hammer and chisel. Just banging out straight lines lol

Could the core samples have been done in the 1800 s? With steam powered core drills ?

It was done probably ten minutes before the show.

Add a watewheel or pedalwhell to core 7 drill platform ,and using dust or some other grit substance and water or oil as lubrication.
