I have already done the glass boring and posted the results of the experiment which is somewhere on the DIF with a full array of pictures, however! idealy it would be good to have what the Egyptians had locally available like the desert glass I mentioned earlier, or the harder type granites.
I do know from the bare copper trials using chirt and olive oil that it works well, but I never tried it on granite because I never had any, it was slow, about 20 minutes to bore through a section of 5.00mm glass plate perfectly, using a small hand bow and pivot, and a one inch hole in a flat wooden board as a guide, once the drill had made a dull scratch or circle it followed it nicely, my wife even helped me by ading new oil every few seconds or so to keep the cutting action going.
The rocking motion of the masons chisel is called boning in as the video showed, where the chisel is moved backwards in order of blending the edge of the chisel to keep it flat, there is somewhere in my saved films a guy who successfully carves a block of limestone using a flint chisel, it takes him only 20 minuttes to complte the task and it is as good as the metal chisel, I will try to find it; this of course is dealing with limestone or the main body of the pyramid and not granite, so this model is already proved many times.
I have also made a simple wood swinging bar system that can polish granite or other hard stone to get the curved surface like that seen on an object of pink granite at the Gizha Complex, the same idea is also used today by lutherers to get the nech board of a guitar curved along the entire length, this was shown to me by a local Guitar maker.
Softer sandstone is also workable using deer antler afte it has been hardened in the sun, quite easily, and even easier with a flint tool with the right angle, and hat is good about flint it can be reshaped very quickly if needed.
Flint type tools are much better, infact, obsidian is used today to make the very finest scalples for eye surgery, they are up to 500 times sharper that steel blades.

I have put all of this to Robert Schoch and he has totally ignored my findings, all he did was invited me to book for one of his holidays, LOL.
I know very well how many people react when they see any of my creations up close, they give you that blank stare of, how, when, why, and do not believe anyone could make such intricate but simple items using very little tooling, a lot of the tooling I made myself, this is because society has had their mojo removed, their hand to eye coordination, which really is the paramount to survival.
Some will say we don't need these things, that is because we are not living in a sentient thinking system any more, our problem solving skills and intuition have died along with the minds of the now skilless, it was done purpously and incidiously without the people realizing it, what seems really simple to myself is seen as impossible by many people below the age of thirty today, I have seen it all take place in a very short time indeed.
Enough rambling, supper time soon.
But granite has to be the benchmark because if the tech can't cope with the hardest examples of what they were doing then the theory falls and granite is a tough prospect!
Limestone is very soft and folk even chip away at that with axes so its a whole other board game tackling granite. If you core your way through granite using low tech then folk will sit up and listen!
