[TowerTalk] GROUND RODS/JACKHAMMERS - FINAL CHAPTER

[Barry Kutner]

Today, rented the 65 lb. Bosch electric jackhammer with the ground 
rod driving bit (they didn't have the bit for the smaller hammer).

As I expected, it was a bear to carry this thing up a 6 ft. ladder. 
To make things easier, I used a sledge to insert the first 2 ft of 
the rods.

The jackhammer drove the rods into the soil like butter. But, when I 
hit a rock, that was it. Only once could I break thru with repeated 
pounding. Three of the rods only went in about 4 feet (must have been 
a big rock!) all exactly sticking up the same amount when sighting 
from a distance.  I cut them off at ground level, and put the 
remaining 4 ft in between the two other rods.

Lessons learned:
1. If using a jackhammer, you do need the bit made for driving ground 
rods.  If using a jackhammer, it would be easier on the back to use a 
30 lb. hammer.
2. Ain't nothing gonna penetrate the rocks!

Next step, Cadwelding them, over the weekend...
