[TowerTalk] Tower base

[David Gilbert]

Since it's a guyed tower you probably won't have any problem, but the 
reality is that your legs are only anchored by a few inches of bolt 
through a brittle piece of stone ... one that's likely to be subject to 
vibration and force from your tower.   It's not likely to sink and it's 
not likely to shift sideways, but I'd recommend you never be tempted to 
mount a free standing tower of any size to those legs ... I don't think 
you could count on it not pulling up.

I had 12 holes drilled in the slab and attached 6 angular irons, two screws per iron to the slab. I then place three "Sonar" tubes over the irons, two irons per tube and filled the tubes with cement. The tower legs were attached to the irons, squeezed in between the irons. (I put a few sections of the tower up, leveled them very carefully and then drilled holes for the bolts through the irons and the legs.
