One detail I've never seen described is the attachment of the copper
(flashing) strap to a ground rod. Is it adequate to simply tie it in
place with wire or perhaps wrap it around about 270 degrees and clinch
it with a couple of bars and some sort of anti-oxident?

I've tried clamps, with less than great success.

The "official" way to do it is to use an exothermic weld -- a small
thermite burn contained within molded clay around the ground rod and
strap to melt the two into each other. This has the advantage of no
welding material to break, and it's actually cheap.
