[TowerTalk] Tower base holes

[Red]

I assisted the back hoe operator by digging the first 10" or so by hand, 
precisely to the dedired dimension or slightly under, in sod.  The back 
hoe did not disturb that.

The bottom wasn't perfect.  I filled it with sufficient limestone 
screenings and tamped the screenings to produce a solid and level base, 
on which I placed concrete 'pills' to support the rebar cage and the 
tower base legs, each 3" from the bottom of the concrete base, to 
eliminate paths for leaching out the natural alkalinity of the concrete, 
which protects steel from corrosion.  These screenings tamp much easier 
than many soils.
