> So, we are talking about the erection of one of the inner horseshoe of trilithons at Stonehenge, utilising the stones used by the BBC in their experiment.

That's the idea, if we can get permission to use them.

> both uprights would have to go into the same hole

Yes, you're probably right. From the pictures I've seen of the BBC trilithon there's not much space between the stones.

24 feet, I believe.

The more forsight we have, the better. Please let us know what problems you anticipate.

> Do we know the dimensions of the BBC stones?

Not exactly. Gordon has some pictures, which I have seen, but not accurate dimensions. The stones are about 32 feet long and the top "half" (I use that term very loosely) has a distinct taper.

I suspect the strength of the tower will be a major safety point. Hopefully Gordon's chippy experience can help there...

Presumably you can amend the model to cater for the change in centre of gravity that this would bring about? I've noticed when playing with the model that it doesn't need much of a change (a few cms) to switch from success to failure, even with the 'ideal' block currently in the model.

>Please let us know what problems you anticipate.

Well, here`s just a couple to start with:

Rowing.

Assuming one tonne of lift per oar, twenty oars spread out over thirty two feet doesn`t leave much room between the oars, especially as they`d have to be closer together near the base of the upright.

Towers.

We wont be able to get away with a flimsy structure under present-day regulations. Serious thought must go into their construction.

Where will the oarsmen stand? They`ll need to be above ground level.
