Stone shifting 5

Levers won't hold themselves upright, each lever needs a man. Why not make the tower also the brace, that way men can stand on top of the tower and control the levers.

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.
