Hello Jon,

Thanks for providing the link to this interesting idea.

I've just watched the video and the technique is stunningly simple, so-much-so I could almost see the AEs doing it.
However, the videoed practical demonstration uses rather light weights and a gradual slope.
It would be most interesting to see the experiment repeated using, say, a two ton block and a steeper gradient.

As for the djed being a winch or windlass, I need to defer to Ritva and others here who know something about AE vocabulary.
