I did this. I placed two, 20' structural steel tubes in side the bottom 
two sections. once the tower reached 40' in height the two tubes were 
butt welded together.  I should have put a 1 or 2' sleeve inside the 
joint though and welded it in as the butt weld eventually broke. As it 
was inside another tube any way I just bolted the whole works together 
with the splice between bolts, but it would have been nicer had it held.
