and the old steel tube,not the ali tube. the whole construction would be made from scaffholding and all the tightened fittings would be welded over. i havent thought more past this but i'll post more if anything else comes up.

of course, the tubes would be going 10ft deep into the concrete.

Yes good idea and also the use of earthen banks to make the structure denser around the base and hide it's size and purpose. Underground cellars for storage, root cellars and a back door way out. 360 observation from the top of the structure and a well for water.
