Larry, can you connect some tinned copper lugs to the lower set of three  
(or six) leg bolts using the existing bolts? For added security, you could 
add  six locking nuts. The ground wires would then connect to the lugs of  
course.

I am in  the process of putting in two new towers on my property (yes, I  am
blessed).

I'm a little nervous about Cadwelding to the  legs.  I suppose you'll all
tell me it has been done dozens of times,  but I have visions of blowing a
hole through one of the legs near the  bottom of my tower.

The alternative, I suppose, is to get a set of  quality ground clamps, clamp
it maybe three times (I assume this would help  the impedance a bit) and the
inspect it over time.

I also plan to  have an extensive "ground ring" around the tower.  On my
current  crankup, I cadwelded to all three "legs" except it was easy to
Cadweld to a  nice thick base and not to the tower, proper.  Effectively
required,  in fact.  So, I Cadwelded to stuff that wasn't a big  deal,
structurally.  Here it would be.

1.  Do I Cadweld  anyway?  How to be sure the tower leg isn't weakened?

2.  Do  I do it to a single leg or all three?  I could "feed" my ground  
ring
from a single leg, I suppose.

This is all in excess of what  Rohn shows, which is a single, clamped line
from the tower, but I've always  taken it for granted the smart thing to do
is have a more extensive  network.  I plan on three rods, connected as a
ring, and then copper  "lines" out from each of them to another rod, a total
of six in all.   That's all easy and been done (by me) before.  Question is,
what's the  best way to connect to the tower itself?  I have the "buried
tower  section" type of base.  We will be pouring concrete late next  week.
So, I have about a month to plan and execute my ground  system.
