Rope lines. Swung from a radius on the ground. Your gonna have to watch the rest of it.I only saw part of it. (I'll look online later today) My question is how did they establish the height of the courses as they went? I didn't follow that.
I saw the the coursing was a reversed arch. How did they maintain the proper elevation throughout the job?
