Ehemals S. 7:
Vielen Dank, auch für die sehr interessante Quelle.
Ja, das ist ein Kurbelbohrer mit in Netzen angehängten Gewichten und unterem gegabeltem Ende zur Aufnahme von Bohrköpfen aus Stein - wie sie auch in der von Dir genannten Quelle und bei [Stocks, 2013] thematisiert werden. An einen solchen Kurbelbohrer ließen sich theoretisch und praktisch aber auch Kupferröhren arretieren, womit er zum Hohlbohrer werden würde.

Sofern ich mich gerade erinnerungsgemäß nicht irre geht Stocks von "Schwunggewichten" aus (vielleicht verwechsle ich den Zusammenhang gerade aber auch mit der von Stocks besprochenen Seilherstellung der alten Ägypter). Der Nutzen dieser Gewichte als fixer Aufdruckkraft ist jedoch unbestreitbar (wahrscheinlich ist von einer Kombi der Effekte auszugehen).

Interessant im Hinblick auf scheibenförmige bzw. trommelförmige Gewichte o.ä. wäre m.E. in Versuchen noch zu erörtern, ob oberhalb oder unterhalb eines Bohrerschafts positionierte Gewichte für bestimmte Einsatzzwecke effektiver sind.

Ich habe zu dieser Art von Bohrgeräten auch noch eine andere Theorie entwickelt (die nicht neu sein muss, dazu habe ich bisher jedoch in Quellen nichts gefunden):
Die Astgabelung solcher Bohrer diente nach meiner Theorie alternativ auch dazu, ein innen (ggf. nur ansatzweise) ausgehöhltes Gefäß aufzuklemmen, um es mit rotierender Bewegung außen in einem entsprechend präparierten Untergrund bzw. einer entsprechenden Aufnahme zu beschleifen (siehe meine Versuche, den auf einen Kurbelbohrerschaft aufgeklemmten Gefäßrohling in einem engen Gefäß in Quarzsand rotierend zu beschleifen).
Wenn ich mich nicht irre gibt es eine altägyptische Hieroglyphe die so aussieht, als würde ein Kurbelbohrer ins Erdreich reichen (horizontaler Strich in der Hieroglyphe im Bereich der Gabelung).
Technisch wäre das beschriebene Prozedere erfahrungsgemäß möglich und Vorversuche zum Thema hatte ich mir bereits seit längerem vorgenommen. Außerdem wäre es auch für Aushöhlarbeiten von steinernen Gefäßen zweckmäßig, anzunehmen dass die alten Ägypter die Gefäße hierfür im Erdreich einbuddelten und damit für die Beschleifung fixierten.
Es gibt auch direkte moderne ägyptische Vorbilder für in etwa affine Herangehensweisen (Nachweise zu dieser Aussage wären von mir noch rauszusuchen).

The documentation of the previous series of preliminary tests and my intention to sign aesthetically (and to meet my requirements) and date the small stone vase with a lid made of Baumberger sandlimestone, which was made in the last few weeks, in a way that is also interesting for me from an artistic and experimental archeological point of view due to the past heat wave, due to missing equipment that still has to be organized and due to handicraft skills that still have to be developed (chasing), took more time than originally planned.
Since I want and have to use the summer for "outdoor work", I am therefore postponing the signing and dating work as well as the surveying work on the little vase with a lid made of Baumberger sand-lime brick (probably) to the coming autumn and winter (but possibly also to an earlier possible date). ).

In the last few weeks I have started another series of preliminary tests at the same time. This series of preliminary tests is about my intention one day - if possible due to the overall conditions - to reconstruct the so-called Sabu disc.
Often referred to as an "Out Of Place Artifact" (OOP Artifact), the Sabu Disk is an ancient Egyptian work piece with very special characteristics. In particular, the thin-walled and filigree nature of the Sabu disc is a major challenge with regard to the processing options for soft stone (but of course nothing generally impossible for a suitably qualified or experienced craftsman, otherwise the Sabu disc would not exist).

For the reasons mentioned, I will therefore make this series of topics a little more dynamic and first devote myself to the preliminary test on the subject of the one day planned reconstruction of the Sabu disc and insert interim thrusts on the previous series of preliminary tests (small vase with a lid made of Baumberger sandlimestone) as soon as there is news on this.

In the series of preliminary tests that have started, I am initially not concerned with the planned production of a copy of the Sabu disc that is as true to the original as possible (scaled down) but with a general testing of the possibilities of "turning off" structures that are as filigree as possible in the style of the Sabu disc on a workpiece made of soft stone that is attached to a two-point bearing axle " to produce.

Preliminary test for the planned reconstruction of the Sabu disc: Production of an approximation model from Baumberger sand-lime brick

[Addendum from 07/23/2023:]
Since the effort of the preliminary test to prepare the reconstruction of the Sabu disc would be extremely high according to my expectations and requirements, I decided afterwards to only do the documentation of this interesting stone processing project in flashs. The following articles will be (and were) changed accordingly without me explicitly going into each individual point of the changes. Content was (and will be) removed by me in places to a large extent.
[addendum end]

. . .

There is no doubt that the ancient Egyptians had the possibilities and skills to turn various stone materials using two-point axis bearing (off) turning processing.
Special exhibits in the Egyptian Museum in Cairo give a small insight into the craftsmanship in this area [see source].

The purpose of this preliminary test is not to show that natural stone can be turned externally (which has long been known and has been practiced for thousands of years): this series of preliminary tests is particularly about narrowing down the most likely methods with which the ancient Egyptians turned stone and about the simplest possible apparatuses that can be derived from this (for which no direct models can be found to this day).

The documentation of the preliminary test, which has now progressed successfully, has been significantly delayed due to another heat wave and extreme weather.
Content will be created as soon as I can.
I will upload more photos as soon as possible.

Update on the current stone processing project:

Up until now, the documentation of the project has not been possible relatively simultaneously with the progress of the project. The project is currently in a critical stage, in a positive sense, in terms of handicraft aspects, which demands my full attention.
I will therefore not upload any further documentation on the project until 21.07.23 at the earliest.
From the outset, I avoided filming the crafting processes in this project and focused on photography, because otherwise the overall effort would have been too extreme.

The Sabu disc is neither a component nor a model of a drive unit nor a ship's propeller: it is a poorly crafted aesthetic vessel as a result of high craftsmanship.

[addendum end]

The project is now relatively close to the final work steps, which will still take a certain amount of time due to the filigree work involved. This is also because the workpiece is now becoming more and more sensitive to damage and is therefore in the most critical processing phases of the entire project.

At this point, highlights of the most important processing phases or processing steps of the original Baumberger sandlimestone blank, which have resulted from the preliminary test so far: I do not provide a detailed documentation of the work steps carried out in this stone processing project due to the enormous effort required for this.

The first turning of the inner thin-walled cylindrical element with tools made of flint and primarily copper can also be seen here on the workpiece.
At this point in the processing progress, the result is already a complete success. This even if the workpiece were to be seriously damaged or even destroyed during processing or transport: for a first approach to this special arts and crafts topic, all the important questions for me have already been answered. The end result of machining the workpiece is ultimately a question of experience and skill as well as patience as well as the material.

By marking the movable bamboo stick accordingly, a fixed measuring depth could be set with the dotting device, which was estimated at around 4 to 5 mm (I will measure it later).

Intermediate summary of the current stone processing project:
[/u]
The preliminary test I am currently carrying out for the one day planned reconstruction of the Sabu disc has been very successful so far. I was able to gain a lot of interesting and important experiences and insights in the various consecutive and distinctive processing steps of the preliminary test as well as the accompanying production and use of the specific tools.
Even if the processed blank made of Baumberger sandlimestone were to be unintentionally destroyed (e.g. due to processing errors or e.g. damage in transit), the results of the preliminary test would be a complete success.
The diverse insights into functioning procedures for the production of the processing result that is now available are an elementary basis for enabling the one day planned reconstruction of the Sabu disc.
The current preliminary test is now entering its most sensitive and therefore also a very meaningful phase, which requires my full concentration, patience, skill, material and tool knowledge:

In the final processing phases of the preliminary test, the following work steps must now be carried out in order to bring the project to a successful conclusion:

- Shaping the vessel as evenly as possible by scraping with coppertools and possibly flinttools to a wall thickness that is as uniform and as thin as possible (in addition, for this final processing step, a correspondingly suitable, as precise as possible measuring tool must be manufactured in the simplest possible way and with means and methods that were also available to the ancient Egyptians.).

- final turning of the drum-shaped middle part of the blank to the thinnest possible wall thickness. This processing step is also critical because the wooden axle inserted into the blank is the one to be finally turned due to the frequent watering of the axle in the past and the resulting swelling of the wood due to the wood pressure could finally destroy the drum-shaped middle part of the blank by the splitting effect.

- as thin as possible turning and scraping shaping of the "segmental arch elements" of the blank

(All three work steps are full of snags in terms of processing technology: the blank can possibly tear off the drum-shaped central part at any time, it can happen very quickly that the wall of the vessel is broken through unintentionally or due to measurement errors; the desired fragility of the surrounding segmental arch elements can, in the case of unfavorable conditions or carelessness or also due to material properties of the worked rock crack or flake off at any time and are thus destroyed.
- Finally, it will certainly be a big challenge to remove the wooden axle that is clamped in the blank without destroying the hopefully finished workpiece.

In total, it should be mentioned that the Baumberger sandlimestone processed in the preliminary test, despite its great softness, is much more difficult to work in the previously used way than it might give the impression: harder vein-like layers are embedded in places in the processed blank of Baumberger sandlimestonek: these lead to a very different reaction of the material to processing in places that are very narrow and can lead to corresponding problems in achieving the final processing goal.

IMG 55: Widening scratch-scraping of the circular crack made on the underside of the blank for decorative grooving with copper tools: since it would have been very difficult to work the fine, scratch-scraping, turned underside of the blank flat, I decided without further ado to turn the original crack into a to rework decorative groove. The area between the ring-shaped, wreath-like rim of the vase and the near-outside curved underside of the vessel to be produced was also slightly reworked by me after scraping: this was to create a slightly inwardly curved accent in this area, which is intended to emphasize the ring-shaped, wreath-like character of the planned vessel rim.

After a few final work steps, this really interesting and meaningful preliminary test, which was quite demanding, is now completed (the pictures of the final work steps will follow).
This preliminary test was extremely successful. As I could roughly measure today, the approximate average wall thickness of the Baumberger sandlimestone vessel seems to be around 5 mm.
But there are also very thin spots on the workpiece to be measured: The thinnest wall thickness measured so far was around 2 mm and was on a side wall of one of the lobes in the area of ​​the attachment to a bowl-shaped segment. I'll measure again to be sure.
With the successful completion of this preliminary test, after an eventful year in terms of preliminary tests, I am going into the early autumn break, apart from possible smaller projects that do not concern larger stone processing projects.

If the opportunity arises, the weight and volume are then determined, the surface is analyzed and the workpiece is measured. But I still have to wait for suitable equipment for this, which can take a few months.
The workpiece should then be signed.

In conclusion, I can state that a reconstruction of the Sabu disc - also with regard to the still unknown material to be processed and the even greater filigreeness to be achieved compared to the workpiece produced in the preliminary test - is a great challenge, but it's not impossible to succeed.

I will briefly summarize the knowledge gained in the preliminary test even i will find time.

IMG 112: The finished and cleaned workpiece made of Baumberger sandlimestone. The preliminary test is successfully completed with this step.

oooooooooo


Today I carried out a small preliminary test and documented it by video recording, in which the bronze chisel kindly made available by forum member LaraC  and cast by LaraC himself with a composition of 89% copper and 11% tin was tested by me on various stone materials.
More on that as soon as I have edited the video material created today, but this much in advance: the chisel was tested in a direct comparison on very soft sandlimestone, hard sandstone and on fine-grained and therefore very dense granite.

[Addendum:]
However, I can already tell you this much: as was to be expected (and has already been proven several times), it seems impossible, even in the preliminary test carried out, that hard stone such as granite can be processed with tools made of bronzes, provided that the processing is not grinding but cutting.

Here is a second version of a short video of the preliminary test carried out for the reconstruction of the Sabu disk, which is planned one day.

[Addendum, 19.08.2023:] The first version of the short video was deleted by me. The link to the second video version has been added here. [End of Addendum]

Here is the first of a small series of short videos (SHORTS) to test the bronze chisel kindly provided by forum member LaraC on stone materials of different hardness (please also note the video descriptions):

[Addendum dated 17.08.23:] Videolink has been edited, there is now a new version of the first video and a republication as a second video on the topic. [End of Addendum]

Since the audio of the video for the preliminary test for the reconstruction of the Sabu disc seems to have gone wrong when uploading it (if the farmer can't swim, it's his swimming trunks to blame), I re-edited the video.

[Addendum:]
The second link also contains the first part of a highly compressed photo documentation of the preliminary test on my YouTube channel in the form of a short video). [addendum end]


WICHTIGER HINWEIS:
Bis auf stellenweise Ausnahmen werden die in diesem Beitrag von mir bisher geposteten Bilddateien annähernd vollständig in Form von Bilderbögen bzw. Bildergalerien in Form von Kurzvideos (sog. Shorts) auf meinen Youtubekanal ausgelagert und in den jeweiligen Posts in diesem Thema als Quelle verlinkt. Ein Anschauen solcher Bilddateien ist dann ausschließlich über die Verlinkung zu meinem Youtubekanal möglich.
Mit dieser Vorgehensweise möchte ich einierseits Datenplatz im Forum sparen und andererseits dokumentarische Zusammenhänge meiner Arbeit besser bündeln.
Von den Bilderbögen auf meinem Youtube wird es jeweils eine Verlinkung zurück zu den entsprechenden Beiträgen im Archaeoforum geben. Unter anderem ist dies technisch notwendig und sinnvoll, weil für Beschreibungen von Zusammenhängen in Youtubevideos nicht ausreichend Platz zur Verfügung steht.
Die ausführlichen Textbeschreibungen zu den Bildergalerien bei Youtube sind dann also hier im Archaeoforum nebst ausführlichen Quellennachweisen abrufbar, während die Bilddateien bei Wunsch auf Youtube betrachtet werden können.
Dieser Umstellungsprozess wird eine gewisse Zeit in Anspruch nehmen.
Außerdem werde ich dieses Thema so wwit wie möglich - auch rückwirkend - auf die englische Sprqache als Dokumentationssprache umstellen.
- Beiträge auch in deutscher Sprache sind natürlich weiterhin willkommen -

Von Beiträgen hier im Thema als Antworten bitte ich jedoch bis auf weiteres abzusehen, da ich mir nicht sicher bin inwieweit dies meine Möglichkeiten, Beiträge rückwirkend zu bearbeiten, möglicherweise einschränken könnte.
Falls Rückfragen bestehen sollten, wendet Euch gerne per PN an mich.

IMPORTANT NOTE:
With a few exceptions, the image files I have posted so far in this post are almost completely outsourced to my YouTube channel in the form of image sheets or image galleries in the form of short videos (so-called SHORTS) and linked as sources in the respective posts in this topic. Viewing such image files is then only possible via the link to my YouTube channel.
With this approach, I want to save data space in the forum on the one hand and better bundle the documentary context of my work on the other.
There will be a link back to the corresponding posts in the Archaeoforum from the picture sheets on my YouTube channel. Among other things, this is technically necessary and useful because there is not enough space for descriptions of connections in YouTube videos.
The detailed text descriptions for the picture galleries on Youtube can then be called up here in the Archaeoforum together with detailed references to sources, while the picture files can be viewed on Youtube if desired.
This conversion process will take some time.
In addition, I will change this topic as far as possible - also retrospectively - to the English language as the documentation language.

However, I would ask you to refrain from posting posts here in the topic as answers for the time being, as I am not sure to what extent this could possibly limit my ability to edit posts retrospectively.
If you have any questions, please contact me via PM.

Here is a little insight (short video) into the possibilities of working hard stone with stone tools in the discussion of alternative theories (in English): the hard stone is worked with pounders of hardstone and flakes of hardstone and Heligoland Flint.

I would like to briefly inform those interested that for me all questions regarding the one day planned reconstruction of the Sabu disk have been answered: nothing stands in the way of the successful reconstruction of the Sabu disk based on ancient Egyptian means and methods that are as original as possible, with the exception of financing (and less luck in the working-process). However, editing and uploading all parts of the video documentation as well as filming the very last workingsteps to complete the sandlimestone test piece documented here still require time.

In the 26th video of the series, I move on to the fine machining of the workpiece and am thus on the verge of one of the most essential steps in the overall process: the severing of the connection between the middle part and the lobe tip on the workpiece.

WINTER BREAK
Although the current stone processing project is close to completion, I am formally taking a winter break and using the time to edit content that has already been posted.
It is generally not impossible that I will not complete the project in the coming weeks or months, but there are currently. no concrete planning.

This topic is currently being fundamentally revised by me. Currently are almost completely deleted in the numerous images posted by me as the author and topic creator (that is: me. Vinzenz Maria Hoppe). The images for topic articles are outsourced. For the illustrations that I plan to make available in other ways in the future, there will be corresponding links in my posts, which I still have to add. All of this restructuring work on my contributions to this topic will take some time. I ask for your understanding and patience. I will announce it here in the topic when the basic editing of my contributions in this topic has been completed.
