I Lesson From History in Bugging In

[Wildman]

i was thinking the other day about this. my thoughts were. a deep concrete foundation with scaffhold tubes (that have been painted with rubberised paint)
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.
