On his website (now only available via Internet Archive), he claims to have used the same Herodotus machine to raise and place the lintel as he did for raising the initial supports:


I imagine once he'd gotten the supports placed, he could just raise the lintel between them with the machine, perpendicular to its final resting position, then rotate it into place.

To get an initial fulcrum under a stone, it looks like he built a wrench-shaped wood frame, essentially attaching a long lever handle to the stone. One can be seen in the second picture on this page:


Things like the very artistic cave paintings and rock sculptures are fascinating. Or monuments. People haven't really evolved that much during the last ten thousand years. It's just some hundreds of generations. We might have more accumulated knowledge and tools now, but people were just the same back then too.

I wish the website any clear information at all about how he moved the blocks (or the barn?!). Is he just lifting and then sliding them? Would appreciate more information if someone knows where to find it.

He explains how he does lateral movement at 1:21 in the video. He's lifting the block enough to get an off-center pivot under it. Once the block is on a pivot, he rotates it 180 degrees, then tilts it onto a new pivot and repeats. Because the pivots are off-center, each rotation moves the center of the block a little bit in the desired direction.

At 2:08, they show the counterweights and one of the pivots he used for moving the barn. (It's a "pole barn", so it has no concrete foundation. His webpage says they had to add about 50% of its weight again in reinforcement so that it would hold its shape when moved this way.)
