A new method by Franz Löhner
For the construction of Khufu's pyramid granite was used for the first time on a grand scale, mainly for the burial chamber, the passages and for the sarcophagus. This page is about how the hard granite could be split and cut. Franz Löhner shows, that granite can't be processed without iron tools!
Cutting granite with bronze or iron tools?
A new method by Franz Löhner
For the construction of Khufu's pyramid granite was used for the first time on a grand scale, mainly for the burial chamber, the passages and for the sarcophagus. This page is about how the hard granite could be split and cut. Franz Löhner shows, that granite can't be processed without iron tools!
Question:
Do you have any practical knowledge of the techniques of stone quarrying and stone processing you describe above?
F. Löhner's answer:
As a young men I worked in a granite quarry in Germany for several years, so I have an intimate knowledge of stones and tools. First I just laughed, when I read about copper tools being used in splitting and cutting granite and copper saws to saw through them. I then thought - that theory will soon be refuted, they just have to try it out with some granite and they will know straight away. This theory has persevered though and so I decided to build the copper tools described by Goyon [1] (these tools are still suggested today by Egyptologists) and determine to what degree the stone would be worn down and to what degree the tools deform.
1. Sawing granite with copper saws:
First I experimented with copper saws made from copper sheets of different thickness. I used soft, half soft and hardened copper sheets and made saw blades with different teeth (wavy, small teeth, large teeth). Then I tried to saw granite, it didn't work, the copper deformed. As an abrading medium I added quartz sand, then Corundum (a gem with a hardness on Mohs scale of 9) and even steel sand (made from steel grit and used to cut through concrete). But even after hours of work barley a scratch was visible on the surface of the granite block. In the same time and with the same effort I surely would have managed to split two or three blocks of granite if using the appropriate tools, ergo iron tools!
2. Drilling with a bow drill and copper bits:
Of course I also experimented with drilling. I built a simple Egyptian bow drill, as shown on several illustrations. After some experimenting I managed to find the right material for the sinew and determined the right tension to use. I used different wooden rods and even copper rods and also used different types of sand and mud. I added water, water and oil, milk and whey to emulsify the sands and prevent the drill bits from heating up too much. But as much as I tried, I didn't accomplish more than a slightly colored spot on the surface of the granite. Only when I changed to a chisel made from steel I managed to drill a couple holes into the granite.
3. Splitting granite with wedges:
I decided to try out an other technique attributed to the Egyptians - using wooden wedges soaked with water to cause the wood to swell and split the rock. I drilled holes and then put in dry wooden wedges and poured water on them so they would swell. But the wooden wedges didn't expand enough and didn't generate enough force to split the stone apart.
HOW DID THE INCAS CREATE SUCH BEAUTIFUL STONE MASONRY?

[The following is the text only, without the diagrams, of an article that appeared in Rocks and Minerals magazine, Vol. 65, Nov/Dec 1990. My thanks to correspondent Wayne Van Kirk for bringing it to my attention and forwarding a copy. See also here for an excellent photographic example of Inca masonry.]
At its height the Inca Empire stretched from Quito, Equador, to Santiago, Chile, along the Andes Mountains of South America. In 1532 Pizarro and the Conquistadores captured the last Inca, Atahualpa, putting an end to this great empire. The Spaniards then proceeded to loot the empire of its vast riches of gold and silver; they melted the precious metal objects and cast them into ingots, which they shipped back to Spain. The "great golden dish two men across" found in the temple of the sun was cut into pieces for gambling chips before being melted (Garcilaso de la Vega, 1961). The Conquistadores did nor ask for what purposes the gold was used; they knew only that the metals were of great value in ingot form. Surely those savages could not have used the gold for anything but ornaments and barbarous religious trinkets; surely they couldn't have used it in their magnificent stonemasonry projects that remain at Machu Picchu and other Inca ruins (figure 1).
Several hypotheses have been advanced to explain how the Inca, stonemasons could cut stones to fit together so tightly that not even a piece of paper can be slid between them. In fact, some of the stones fit so tightly that I could not even blow air between them. Protzen (1986), following Bingham (1913), concluded that the stonework had been done by pounding with quartzite hammers. Jessup (1934) and Goetz (1942) championed grinding and polishing with sand and water. Bingham (1913) and Frank (1980) thought that the stones had been cut and shaped by wedging, using wood, metal, freezing water, or the expansion of heated vermiculite. Arnold (1983) proposed the use of organic acids.
Hypotheses
Hammering. If one tries to shape a stone with a hammer (Bingham, 1913; Protzen, 1986), the smallest inside corner that can be produced must have a radius larger than the smallest radius of the hammer. The mason must be able to strike the material that is to be removed. Therefore, an observer must not see inside comers with radii smaller than than the size of the hammers used to produce those corners. Figure 2 shows one of many inside comers that have very small radii. To fashion these, the stone hammers would have to have been extremely small chisels. Furthermore, when a rock is hammered it tends to break selectively along planes of weakness, such as mineralized fractures. Even if it does not break completely, the rock will chip out at the intersection of the cut surface and the fracture, producing a groove at the intersection. Thus, fractures as shown in figure 3 would not exist. It is concluded that the blocks could not have been cut and shaped by hammering.
Grinding and polishing. This process, suggested by Goetz (1942), could produce inside comers of varying radii as well as cut surfaces intersecting low-angle fractures. However, if a rock containing quartz is abraded with river sand, which is mostly quartz, the softer minerals in the rock will be sanded out, while the quartz grains will hardly be scratched. Indeed, sanding granite with quartz should result in quartz grains standing in relief above the rest of the sanded surface. While I have no illustration to show that this relationship does not exist, I did observe that there were no quartz grains standing above the rest of the minerals on the surface. Thus, I conclude that those beautiful Inca stone surfaces could not have been produced by sanding.
Wedging. If wedging (Bingham, 1913; Frank, 1980) had been used,
Why is it that people are so willing to think that humans aren't capable of amazing things. Especially considering these amazing things were done with hundreds of thousands of slaves, if not millions.~Tenth

I just gave you an experiment that makes sense when mastered, they even tell you how to avoid V cuts..
Just because it doesn't make sense to you, doesn't mean i should use my Sunday convincing you with more experiments.
"We're going to put sand inside the groove and we're going to put the saw on top of the sand," Stocks says. "Then we're going to let the sand do the cutting."
It does. The weight of the copper saw rubs the sand crystals, which are as hard as granite, against the stone. A groove soon appears in the granite. It's clear that this technique works well and could have been used by the ancient Egyptians.

This is a pretty interesting video I just started watching.. I'm going to be on Egypt all day now haha.
It's Engineers, Geologists, architects..
Now I don't know if they make any conclusions, and before I confuse any more people I'm just putting the video here because so far they are EXPLORING... I hope that's what the whole video is. I don't want an answer.
So here if anyone wants:

Copper adding sand doesn't work according to this man below who has experimented with the copper saw sand combination. Its a fallacy unless a person can link a video which shows it happening and is effective enough to produce the cuts observed.

So link the entire video a still picture means nothing as proof to me, sorry.
And please don't use the fantasy crap on me unless you can do that. Im happy to be convinced, if you can provide an unobscured video which has enough details added to see who was there, what time/date the test took place, type of saw used etc etc, I notice in your berating people in Ufo threads you demand no less and so im demanding no less than the standard you set for others.
It was 16 years ago, if you care nothing for the truth and wish to remain ignorant do so. I linked you the NOVA website. Copper and sand will work, proven 16 years ago. Feel free to buy Denys Stocks book if you want. Or stay ignorant, your choice.

Your rude and your replies show ignorance and hypocrisy but that's you mate, ive seen enough of your replies on ATS to expect a reply like the above.

I sourced it. It's a reputable source. You can't debunk it and know you are down for the count. Sand and copper work, it's been done experimentally and it worked.
