The Total DIY Guy in me says "kewl". But where do you get this stuff? Is
it still available, or is this something that came from some
well-stocked electrical parts store of yore?

Carbon rods are available at any welding supply store. Theater supply
stores used to stock electrodes for carbon arc lamps. And there are
specialty firms that stock the high current copper-carbon brushes used
in starters and generators HTH

Sounds good if I have to, but how could I attach the braided copper
wire that these brushes have?
Or otherwise connect the brushes to whatever they're connected to?

File a groove around the back end of the carbon, wrap end of
braid in the groove and "tin" the braid. It gets real
snug when it cools.
Or drill a small hole and pin the braid in it.
You can actually plate copper to the end stuck in copper
sulfate with a piece of copper and power supply, but that's
too much trouble...
