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...
