[TowerTalk] CDwelding a tower leg

[Frank]

Nope, never been hit by lightning in over 30 years of hamming.  
Evidently you have had that misfortune.

Ever wonder if there might be something you don't understand about 
static build-up?

My tower is grounded by virtue of the tower leg bottoms stuck in sand 
and dirt below the concrete.  I don't need any additional grounding.

The tower acts like a big lightning rod.  Contrary to popular belief, 
lightning rods don't attract lightning, they dissipate static charge.  
At least mine seems to work that way.  Your milage may differ.
