intentions are good, and appreciated, but w/o knowing the
type of ground someone has your advice may or may not be of
much help. I will share a story about my quest to drive in
about a dozen 10' long ground rods each 5/8" dia steel,
heavy copper coated into very nasty hard ground.
I tried resulted in total failure & frustration. This
back when I was healthy and thought nothing of swinging a 10
pound sledge hammer all day. My ground here in NE Indiana is
some form of horrible nasty good for nothing clay/shale mix.
You can get a rod pounded in about 2' with great effort and
then all you will do is mushroom the top of the rod and end
up with a sore back with an 8' rod sticking out of the
ground that cannot be removed. My 2 acre pond holds water
trick I had ever heard of w/o success. Tried beating the
crap out of it with every hammer I owned, no luck. Tried the
heavy steel pipe with massive metal cap and handles, same
results. Tried a 3/4" conduit pipe sharpened at the tip and
a garden hose attached at the top with a hose clamp (and
water turned on full flow) and repeated thrusts up &
down hoping to make a water drill, zero luck and a huge
mess. Tried to fill the started holes with water and let
them sit for several days to loosen up the crap
below.....the water level NEVER went down.
What I did
end up using that worked like a gift from heaven was renting
an electric jack-hammer that weighed about 80 pounds and
stood 3-4 feet tall. You remove the huge 10 pound steel bit
that normally goes into the hammer and you are left with a
nice 1.5" dia hole maybe 8" deep that fits very nicely over
the top of the ground rod. I sat up a step ladder next to
the rod, lifted the jack-hammer up over the ground rod and
let it rip. The ground rod drops in length like magic just
from the weight of the hammer slamming away. Total time per
rod is about 5 minutes. If you have normal soil those other
techniques may work but if you have this crap we have here
called ground then the jack-hammer is the only way to go.

Dribble a hose where you want the ground
rod to go in overnight with a very slow dribble so the ground
absorbs it well. Then push the silly thing in with your hand
unless you have very rocky soil. In that case the ground rod
is never going to go in nicely.
The approved tool is a 2' section of galvanized pipe with a
cap on it. That will drive it in straight with modest effort.
At least that's what I am told. I used the dribble technique
and the rod went in like a warm knife into warm butter. It
didn't quite sink on its own. I live in a former flood plain
for very serious storms. (As in 1969 shortly after I moved
into Ca we had Cosby weather. "Let it rain for 40 days and 40
nights until the sewers back up." We desperately need that
sort or weather again.)

At this juncture I should point out that I did not ground my
installation by conscious choice. I actually have an 8-ft
ground rod and was prepared to get everything properly
grounded, but I just never got around to picking up the hammer
drill to drive the thing into the ground. It's a good thing
too, because I'm about to move all of my equipment to my other
QTH we're grounding should be much easier to accomplish.
My plan is to properly ground and bond the station.
