I've been wondering about how we actually place the lintel on top of the uprights. I can think of three methods:
1. Crib it up parallel to it's final position, but far enough away from the uprights to not impede the levering (20 feet), then lever it over bridging logs to its final resting place.
2. Crib it up at right angles to its final position (plenty of room for levers), lever it across the top of the uprights, rotating it into position as we go.
3. Crib it up in line with it's final position at the side of the trilithon (plenty of room for levers). Row it straight across the top of both uprights into it's final position.
The last method seems like it works the best for our stone-rowing methodology.
