Advanced Machining in Ancient Egypt
Page 3

By Christopher P. Dunn
Petrie also studied the sawing methods of the pyramid builders. He concluded that their saws must have been at least 9 feet long. Again, there are indications of modern methods of sawing on the artifacts Petrie was studying. The sarcophagus in the King’s Chamber inside the Great Pyramid has saw marks on the north end that are identical to saw marks I have seen on granite surface plates.

Today, these saw marks would reflect either the differences in the aggregate dimensions of a wire band-saw with the abrasive the wire entraps to do the cutting, or the side-to-side movement of the wire or the wheels that drive the wire. The result of either of these conditions is a series of slight grooves. The distance between the grooves is determined by the feed-rate and either the distance between the variation in diameter of the saw, or the diameter of the wheels. The distance between the grooves on the coffer inside the King’s Chamber is approximately .050 inch.



Egyptian artifacts representing tubular drilling are the most clearly astounding and conclusive evidence yet presented to identify the knowledge and technology existing in pre-history. The ancient pyramid builders used a technique for drilling holes that is commonly known as "trepanning." This technique leaves a central core and is an efficient means of hole making. For holes that didn’t go all the way through the material, they reached a desired depth and then broke the core out of the hole. It was not only evident in the holes that Petrie was studying, but on the cores cast aside by the masons who had done the trepanning. Regarding tool marks which left a spiral groove on a core taken out of a hole drilled into a piece of granite, he wrote:

"The spiral of the cut sinks .100 inch in the circumference of 6 inches, or 1 in 60, a rate of ploughing out of the quartz and feldspar which is astonishing."

After reading this, I had to agree with Petrie. This was an incredible feed-rate for drilling into any material, let alone granite. I was completely confounded as to how a drill could achieve this feedrate. Petrie was so astounded by these artifacts that he attempted to explain them at three different points in one chapter. To an engineer in the 1880’s, what Petrie was looking at was an anomaly. The characteristics of the holes, the cores that came out of them, and the tool marks indicated an impossibility. Three distinct characteristics of the hole and core make the artifacts extremely remarkable. They are...


1. A taper on both the hole and the core.

2. A symmetrical helical groove following these tapers which showed that the drill advanced into the granite at a feed rate of .100 inch per revolution of the drill.

3. The confounding fact that the spiral groove cut deeper through the quartz than through the softer feldspar. In conventional machining the reverse would be the case.

Mr. Donald Rahn of Rahn Granite Surface Plate Co., Dayton, Ohio, told me, in 1983, that in drilling granite, diamond drills, rotating at 900 revolutions per minute, penetrate at the rate of 1 inch in 5 minutes. This works out to be .0002 inch per revolution, meaning that the ancient Egyptians were able to cut their granite with a feed rate that was 500 times greater.

Dates
Egyptologists, archaeologists, and scholars from the 19th century have proposed different dates for the era of Menes, or the date of the first dynasty:[14]

John Gardner Wilkinson (1835) – 2320 BC
Jean-François Champollion (1840)[contradictory] – 5867 BC
August Böckh (1845) – 5702 BC
Christian Charles Josias Bunsen (1848) – 3623 BC
Reginald Stuart Poole (1851) – 2717 BC
Karl Richard Lepsius (1856) – 3892 BC
Heinrich Karl Brugsch (1859) – 4455 BC
Franz Joseph Lauth (1869) – 4157 BC
Auguste Mariette (1871) – 5004 BC
James Strong (1878) – 2515 BC
Flinders Petrie (1887) – 4777 BC
Modern consensus dates the era of Menes or the start of the first dynasty between c. 3200–3030 BC; some academic literature uses c. 3000 BC.[15]

Have you got any specs on that dril Roc, speed, top pressure etc, material and so on.

There is still lost more to this subject,

What I think we are dealing with here, is two distinct periods of history and the artefacts that are available to examine today, it is clear that the quality of these items wheather they be metals or stones are not all of the same quality, or time period, this is blatantly obvious when you closely examine them.

Many leading authors mention high tech machinery or engineering in Egypt and other places where this advanced technology was used but not when, and herein is the human problem, one cannot compartmetalized different periods of history into one genre.

I also think that there was advanced engineering that was taken around the world and used to create many of the artefacts, but not left behind afterwards, this is why we see a distinctive pattern the world over, IE, the people living in and around these monoliths simply went back to how they were afterwards, IE, the complexes fell into ruin and they never kept up their maintainance, this indicates a removal of the tech itself when those who used it took it with them when they left.

My part in this debate is to try and recreate the same quality of work with what the experts say they ancient Egyptians had vailable to them, IE, copper/bronze alloys and other aggregates and that is what I will attempt to do to the best of my ability as an engineer.

I already knew they can drill holes faster before reading the article we need to keep in perspective, keep the alien rhetoric out of the running.

Forester is being sellective with the reality of the subject, he never comes out and explain things properly as that would spoil his method of making money out of the mystery.

There are so many others on the same band wagon, giving only half of the information and leaving the rest to imagination, I don't work like that.

What my experiments will endeavor to show is, there are other ways to swing an Egyptian Cat, using the old school tech, which he never does, the experiments he has been a part of are a complete joke to any other than the trained eye.

Lets see what I can achieve and gain from using my own brain instead of following his and his stories of old.
