I have built a 12ft x 16ft backyard workshop. I have plans for a 30ft x 40ft garage. Both are required to have 1/2 inch x 10ft solid copper electrical grounding rods driven in the ground. 3 inches has to be left above ground for connecting to the rod. Our soil has rocks in it, but they are mostly small, between quarter and fist size. I've only driven one in the ground before. I used a post driver made from heavy tubing with rebar handles on both sides. It took two days, moving the rod to several different spots, and bending it several times, before I got it in the ground. I don't want to do that again. I'm not even sure I am physically capable.
So here I am, inquiring about building a cheap ground rod driver. Anyone have any ideas as to how to go about building something to help drive these things into the ground?
