Having made 3 stone circles, I found that a system that had planks, then round lengths as rollers, then more planks on top, with the stone placed on the planks and levered onto the rollers, worked a treat. Apparently they move houses thios way in the states...The bottom planks and rollers can be moved along as the stone moves. We moved several stones this way, with 2-3 people pushing 2-3 ton weights.
Something is not right. This message is just to keep things from messing up down the road
