"I always thought that dragging these huge stones was physically impossible because of the friction on the surface. The key thing is the technology was always there around them," he said.
It is the movement of the 60 famous Bluestones which causes historians such problems. Each stone weighs up to 4 tons and they originally came from the Preseli Mountains in Wales – some 200 miles away.
Mr Lavin has come up with a cylinder ‘basket’ to roll the massive and irregularly-shaped stones.
The basket is created by weaving willow and alder saplings to form a lightweight structure that can be easily moved by 4 or 5 men. To complete the rig and to ensure the best rolling and floatation conditions, the gaps between the basketwork cylinder and the irregular stone are packed with thin branches.
This spreads the load as the basket flexes in transit, much like a modern tyre, and creates buoyancy when transported down rivers and across the sea.
One of Mr Lavin’s key discoveries during his earlier experiments was that the wicker cages that contained the stones were able to float. This would have enabled Neolithic man were able to get the huge stones across rivers on their journey, as well as making it easier to transport them over long distances without having to carry them the entire way.
