Looking good, let me get this straight, you've got a rope going from the top of the stone to the top of an "A" frame, with a 3 ton weight hanging in the middle. So the pull on the "A" frame is equal to the pull on the sarsen. It will take some anchoring.

I'm still thinking about levering from the tower, if we do the initial levering with the levers starting at an angle of 45 degrees (instead of vertical or 70 degrees to be more accurate) then the levers will be at 90 degrees to the diagonal bracing logs creating downward pressure on the tower. That way we'll need less anchorage on the tower.
