Hallo Mela,
wie gesagt, mein englisch reicht nicht, um die technischen Dinge zu übersetzen, und der "babbelfish" übersetzt nur wirres Zeug
Auszug:
Much of the rough shaping of the stone vessels by the ancient Egyptians could be accomplished with simple hand-powered percussion and lapidary tools. The ancient Egyptian's choice of tools would depend on the type of rock used in the vessel, the amount of waste rock that needed to be removed from the initial block of stone, and the vessel's form.
Percussion tools may consist of metal chisels (hardened copper (cold-worked and arsenic alloy) or bronze, e.g. UC7240, Fig. 9) for use on most softrocks, such as porous limestone (Stocks 1999), and stone mauls (e.g. UC30858, UC30184, UC16328), hammerstones (e.g. UC44234), pecking hammers, pounders (e.g. UC27323, UC35981, UC379, UC21411), chisels, and punches for both softrocks and hardrocks. (Engelbach 1923, Zuber 1956, Stocks 1986a; 1999). The process of working porous limestone and similar rocks is easily done with these tools, however, carving igneous rocks like granite is a slow process (Stocks 1999). Examples of unfinished stone vessel exhibiting marks from percussion tools are also known (Fig. 10, e.g. UC36879, UC6934, UC33304, UC33306, UC33307, UC33308, UC33310, UC33311). Zuber (1956) conducted an experiment in the use of flint percussion tools to carve a small Egyptian style bust in granite, it took approximately 36 hours to complete the carving of the statue's form, but involved no polishing of the surface. Stocks (2001) conducted hieroglyphic carving experiments in granite using hammer-driven flint chisels and obtained a rate of 5 cm3 per hour of rock removal. Engelbach (1923) conducted granite quarrying experiments using diabase (dolerite) pounders at Aswan and obtained rates of 450 cm3 per hour of rock removal.
Core Drilling of the Vessel's Interior
As of yet no tubular barrels made of copper or the wooden drill-shaft used for coring of rock have been found in the archeological record from ancient Egypt, Crete, or Mesopotamia where rock coring and stone vessel making was employed (Warren 1969, Stocks 1993). For the copper barrel, this may be due to the wearing down of the copper tube to lengths that were no longer usable, at which point the remaining copper tube was recycled (Stocks 1993). The use of bow- and hand-powered coring drills (Fig. 13) as a method of cutting rock is inferred from marks observed on ancient Egyptian stoneworks, and includes pieces of waste rock, as well as finished and unfinished stone objects (Copper coring drills). Traces of verdigris, either copper or bronze, as well as abrasive have been found in core holes in both Egypt (Reisner 1931) and Crete (Warren 1969).

Mit einem Hollunderstock lässt sich sowas wohl nicht herstellen:

Vieleicht kann das mal jemand sinngemäß übersetzen ?
