I can remember moving large stones when constructing garden rockeries using exactly Gordon's method using a scaffold pole and a brick for the fulcrum. Never occured to me to scale the whole thing up! Doh!
I wonder how many people will say "me too" when they hear about it. We've all been there, done that with levers, even the concept of shuffling something into place with sideways movements, but Gordon's application of the idea to large scale transportation is pure inspiration. Why has nobody (except the builders of Stonehenge, of course) thought of it before?
