When I put up my 80-foot self supporting tower, I bolted the first
section to the stubs and built a framework to suspend that in mid-air
over the hole. I plumbed that before the concrete was poured and
double and triple checked it for plumb as the concrete was setting. A
week later I installed the rest of the tower and it was dead on.
