Oh cool. I didn't have luck finding it before, but that "Machine de Metagenes" is exactly what I think would be the easiest method of moving a
large stone block over any distance. So at least now I know what it's called and that some documentation of its use in a pre-industrial era
Looking at that picture, I'd almost bet those circles around the rim aren't bolts but holes. Because those are needed to get that big stone up an
incline. Those holes would go over ramps with cog pins that would prevent slippage. On the topside levers would be placed in the same holes. Ropes
would be used to pull those levers, and since the roller is prevented from slipping by a mechanical interface, a torque action would be used to crank
that block uphill with good mechanical advantage. (Not to mention the ropes pulling the lever could be pulled by another lever anchored in a way to
provide even more mechanical advantage.) Rollback is prevented by placing some type of chocks behind the rollers as they go uphill. Of course that
part of ancient construction is likely the most difficult and dangerous aspect (obviously), but seems quite feasible if not the way to do it.
I'd almost be willing to bet that if there were any limiting factor to the slope in pyramid construction, it's due to the amount of effort getting
those blocks uphill with that method, or that a steeper slope would have broken the materials available at the time for use in cog pins or levers.
On a side topic, some ancient lapidary tools are hard to find or aren't that well documented... But I can't help thinking that those Bi and Cong
artifacts which are found in China when combined would make an excellent rotary buffer with the addition of a wooden shaft and use of a rope and/or
bow. They look like they have some heft to them and seem about the right size. Then it's a matter of having a rope fixed to two points or on a large
bow, wrap that around one end of the shaft, it passes through the cong block and is then attached to the bi. Put a fleece over the bi, use some kind
of cutting compound spread on the fleece, and pushing it (or the bow) back and forth should work to polish a large flat surface. Seems mundane,
considering how Bi and Gong artifacts are often carved up and presented as decorative objects. (But no reason why you can't make art out of stuff
when it is no longer needed for usage as a tool. People do that all the time.) Also it seems possible that something like that could have been used to
smooth and polish large stones elsewhere, even if few or no artifacts remain. Sandpaper as we know it may not have existed back then, but abrasive
materials, animal skins, and some elbow grease could do a nice job of taking out any tool marks.
