Stone shifting 5

Hmm.. I was trying to avoid having to build the tower up to 24 feet when it only needs to be about 14 feet to get the stone to 70 degrees.

I wonder whether somehow we could lever the props from ground level.

Another 10ft with the stone out of the way is no problem. We can use the weight of the lintel to stabilise the tower. I can see no practical way of operating the levers without men on the tower to control them, even at an angle of 45 degrees to ground level the levers will have a mind of their own otherwise.
