Very cool - thanks for the updates
I "get" how the original gang went about making square-ish beams with hand tools 6 - 8 centuries ago.
Then I watch the video of the tower crane used in the lift - and nope. Don't get that at all. Did they hoist the truss/rafter components and assemble up on top? Doesn't seem like they could hoist a finished rafter into place. But then - Stonehenge.
Fascinating. I'm good without knowing how stuff was done eons ago.
