Jerry speaks the truth. A rented trencher, like a Ditchwitch, would
make short work of your trenching project. I dug trenches for my grounding
wires and for my conduit system in one day with a rental.
Jerry is also correct in suggesting that the molten shot is running out
of the holes in the (I assume) One-shot Cadweld molds. I had the same
problem with the first one I tried. After I cut off the half-welded top of
the ground rod and fixed a second ceramic mold on top of it, I sealed the
holes for the side wires and around the rod itself, underneath the mold,
with electrician's putty (available at Home Despot, Lowe's, etc.) I did
twelve welds successfully thereafter.
Good luck with the project.
