I agree with Jim, K9YC on this. Grounding is for lightning
protection. To be effective, it should be outside of the
structure/house and be very low resistance. And all driven grounds
must be bonded back to the AC Mains ground. This is per NEC. Your

Cad-weld seems a easier than the other approach described. It is more robust
against corrosion, plus it is fun.
