Stone shifting 4

Right Steve we have two methods to move the stone upright. as yet some details to work out with both. Both retain the principal of basically useing levers and logs.

Just a quick thought on how to stablise the tower once the stone has been launched. Perhaps we can tie the diagonal strutts to the bottom of the stone, as the top moves say 6 inches or so the bottom will only move a fraction, by bottom I mean ground level. This will just have the result of tightening the anchor rope. we can then slacken it a bit before the next movement. I'll keep thinking.

If I can think of a way to anchor the tie rope to the bottom of the stone we can tension it with a Spanish Windlass, if we do need to reduce the tension as the stone moves then it will be easy.
