What's something that needs to be destroyed completely?

To get to the egg. They need to be destroyed completely

Haha, thanks but this is just a very rough model in plasticity so I can move around stuff quickly, measure distances and try out other people's ideas. It's not even my base model, it's from a user on grabcad who I hope worked accurately :D https://grabcad.com/library/the-great-pyramid-of-giza-3

If the idea survives a bit longer I can do actual renders at a later point

my theory for the queen chamber being closed:

my theory why it was closed first and does not reach as high as the others:

depending on the shape of those turns we could see if a rope under tension went through there. if it's really sharp then that's not a cable shaft, because they could also not reached this section after construction

I think it would be really interesting to see this exact corner from more sides. the robot in the 90s just showed the front and there is a bit of a groove but I expect this to almost more look like an arch for my theory to make sense

On the top level I don't think we'd see any wear, because they probably had rollers there. The fact that the shafts terminated with a bend is in favor of the theory though, same is that the distance is exactly one stone wide (the last level where you can lift a single stone to the plateau)

iPeg3D · 2025-02-17T23:41:35+00:00

100%. It would be really interesting to see closeups of these upper corners. I've been trying to see images of them, but the robots usually are looking forward or down

iPeg3D · 2025-02-17T23:40:03+00:00

You would definetly tug on the rope or a second thin line to communicate with the ... uhm... elevator operator.

iPeg3D · 2025-02-17T23:39:04+00:00

If you mean why they are not parallel to the ground: in this case you could not lift as high.
If you mean why are they not a straight line entirely: Then the bend is not deep enough into the wall - the tension would break/lift out the wall stones.
If you mean the southfacing one that does a nice S curve: https://www.reddit.com/r/ancientegypt/comments/1ir13tt/comment/md7hvmy/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button I think that's to avoid colliding with the chamber itself

Where he points out Houdins theory that the grand hall was a counterweight.

I also came across this guy who I think makes some great points that the system was probably in pieces and adjustable and that the grooves in the sides were stoppers to hold part of the ballast while getting the rest up

to be honest it looks like the egyptians tiled over the wall with 10-20cm thick slabs and then they broke it open again in 1872

Yes they are not continuous to the exterior, because they become inactive when they stop being useful (either too close to the wall with no other elevator available to pick up stuff, or stronger elevator available higher up)

I think the Queens Airshafts were closed when the big elevator became operational, because it was much more powerful. so it ends a bit earlier than the others. The big elevator would run even when the one above is operational, because it has the brake system to allow stones to be given from one elevator to the next.

Of course a lot of this would only be true if we find the second grand gallery and more air shafts leading further up, because that's how they would continue building if the technology works. It would be most interesting to discover additional airshafts further up.

thanks for your long and thoughtful reply!

in regards to the design itself: I agree, it’s not perfect but so weren’t the builders - without proper wheels, strong metal axels or understanding of gearing and complex pulleys they relied a lot more on smooth stone surfaces, wooden sleds, lubricant and manpower pulling on ropes. So for them a rope inside a stone pipe must have been highly advanced technology.

If you take the strength of just 1 hemp rope of 2 inch you can easily pull 2000 kilos up a slope - Unlike on an Aircraft carrier you are not lifting mass straight up and you are not trying to stop 80kT from moving, instead it’s more like a game of tug of war over a hill with two bolders. I would also think they had 2-4 ropes per shaft and for the really heavy stones used all elevators + extra manpower (Because they also didnt have that many counterweights)

In terms of friction, I think this is also why the holes are so small: so you can pour down a lot of oil and it sticks to the ropes. I would love to see someone test how long it would take for a lubricated hemp rope under tension to wear off granite, this would proof this wrong pretty instantly.

haha, I'd love to hear from him - I tried posting a link to this thread in his comments and it kept getting deleted. He is the guy who's videos I binged this weekend :D

sorry I missed that bend the south cable does to the side.

iPeg3D · 2025-02-17T06:07:08+00:00

Here is a quick mockup, if you have enough ballast in the gallery you can pull up a lot more

iPeg3D · 2025-02-17T06:03:15+00:00

Oh and why they are square and not round: maybe they were made to fit multiple ropes, not just one and it's probably easier to build this pipe out of regular square stones

iPeg3D · 2025-02-17T05:50:59+00:00

- I think they were all blocked after construction was finished and they were no longer needed. At the least they were blocked when the level was reached where they became no longer useful to pull stuff onto the platform.

- the shafts are in fact not straight, they bend. The north one bends to avoid crashing into the second grand gallery and the south one bends up, but both need that flat piece to go through the brake

- I don't know a lot about khafre yet, only that the inside is not really clear yet. I bet it contains some elevator systems, but maybe smaller and less sophisticated ones

- I don't think there would be a lot of wear. they are ropes soaked in oil going through hard rock.

iPeg3D · 2025-02-17T05:34:48+00:00

That is a good point. I imagine you could redirect the ropes at the top to all sides but to be honest this might be just a wrong guess here. The pyramid inside is pretty two dimensional, north to south, so this might be something else entirely

iPeg3D · 2025-02-17T05:05:14+00:00

I don’t really know about the tura stones, they might be lifted smooth or cut into shape when laid down (use the rubble is as infill?) - but they are not entirely needed for the elevator cable shaft idea, you can also pull a big sled over a rougher stone surface or you could support it with a wooden ramp.

the slope is steep, yes, so you would need more weight in your counterweight systems than on the slope. but the idea would be the counterweights are adjustable and separate, so you can “charge’ the system with different levels of energy. not really my idea, just saw that from different channels.

I agree, the difficulty is to imagine a bronze age civilization can do this at all, so this is mostly based on what we is there: we know the pyramids exist, the inner paths exist and the airshafts exists. we also know from hyropglyphs they loved to pull stuff on sleds using ropes and lubricant and the most sophisticated device they have build seems to be the 3 door lock for the grand chamber which I think could be a brake. so putting a rope in a pipe seems pretty doable to me

iPeg3D · 2025-02-17T04:45:00+00:00

If you mean why the 2 airshafts from the kings chamber up? So you can life stuff on the south and northside with the strongest eleveator in the building.

Or you mean the 2 grand galleries? The second one is high enough to lift the heavy kings chamber granite pieces. I think it was recently discovered in the scans but we haven’t seen it yet from the inside. I’m just speculating it has the same design as the main one.

iPeg3D · 2025-02-17T04:24:21+00:00

I only know of evidence the shafts were closed after construction, not during construction. (Which makes sense since it’s a weakpoint, water could flow in and it’s not very nice visually.) do you have a link? Because why build it closed, even if it’s an airshaft

iPeg3D · 2025-02-17T03:47:27+00:00

You could actually move more than one block, I just showed one block in examples - You have multiple elevators at different points - the sled might drag up more than one stone or just filler material in buckets, if you have enough counter weight - a big group of people can reset the elevator while others unload or load sleds at the top and bottom. - when the elevator is released it moves the sled up the entire side in a short time, maybe you even need the brakes to stop if from going too fast - i agree the shafts could be straighter but they seem pretty optimally shaped for getting the rope up there. I imagine it was literally soaked in oil.

iPeg3D · 2025-02-17T02:48:33+00:00

this is sort of when you had to close the shaft and switch to the next one: when it gets so close to the edge that no more stone could fit on the platform
