Stone shifting 5

I was flinching at the cost of replicating large quantities of Neolithic rope for use in the project. A small piece for testing should be OK.

If we haul the stone up from 70 degrees, the initial strain on the rope(s) would be about 7 tons, provided that the angle is not too steep (i.e. a long rope).

That's it exactly 7 tons compared to 200lb.

Sorry Nigel, as far as I know we are still talking about doing it two ways, talking being the operetive word, nothing is decided, but I still think we are over-engineering the erection bit.
