Gordon will have to invent log rowing, or pole vaulting....

But do you know approx what it would weigh? We know we have the method (a) to move it into position and (b) to lever one end up.

Thanks jimit. I just got in from work and had a quick catch up. I think you are making things far to complicated, let's try the simplest method first, that is just use the logs and levers we use to move the stone.

I've been thinking about it all day at work and I don't see anything difficult about what I suggested this morning. Levers from the top of the tower should have it upright in no time.

Much heavier than the stone? Hardly, but it would certainly be quite a problem to handle it.

In answer to Nigel's query about the height it would be 39 feet off the ground. Hmmm.. not too easy to load up. If we can get the monolith to 80 degrees the problem is much less. The pulling force is halved, so we can use a 50 foot pole with the same weight and the height is halved because of reduced angle and halved again because of the shorter pole. So we heave a height of only 10 feet, which is much more reasonable.
