Hi, I'm back (said with a heavy Austrian accent).
So if you're letting the fulcrum log slide down the stone that's pretty much what I was saing yesterday, except that you also have some guys up on the tower to look after the levers. OK, under these conditions the tower takes no loading at all and you are merely using it as a personnel platform.
With regard to the pole method, I think it is entirely in keeping with our approach in that we raise the lintel stone (and the pole with it) using levers and crib, then we attach the rope and then lever the lintel back down to the ground again, all using your original idea.
