Oh come on. Stonehenge was named for it's hanging stones, i.e the lintels. Yes, any other henge is misnamed, but as 'henge' had come to describe the monument as opposed to the hanging stones (and it was a while ago). I think we can excuse the terminology. Anyway, in that case Stonehenge is the only henge that CAN call itself a henge.
Having had it pointed out to you that you have used completely the wrong word to describe your contraption cannot be dismissed with the words 'small point'.
Someone mentioned to me the 'ratchet-theory' i.e. any small point made to enhance a theory is jumped upon and used to advance ones ideas but, like a ratchet spanner, this is one way traffic and one chooses to dismiss any points that serve to show it to be unfeasible.
May I echo the comments of my fellow contributors and thank you again for your polite replies and gracious behavior, but may I also suggest you read through all these posts, put the kettle on, sit back and have yourself a serious re-think.

Respectfully,

Mark
