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
equipment, your house, and your life may depend on it being done correctly.
Yes, the Cad-Weld fireworks are indeed impressive. And when finished
one has a connection that will survive reliably underground for years
and years. Where as a mechanical connection is only good for a few
years and less if buried. Something about dissimilar metal chemical
reaction.

This is probably overkill for QRP but I wanted to do it right like we
used to do in broadcast.
The primary purpose of grounding bonding has NOTHING to do with radio
-- it's for LIGHTNNG PROTECTION!

Yes, it certainly is fun! I summoned my XYL and the neighbor's kid to
watch. :)
