Now on a quest for a Negative "fat wire" bypass/aft buss.
For ha-ha's we crushed some 1/2" copper plumbing pipe as a mental primer to begin search for a aft bypass/buss, (think blue (for pressure) not red (for heat)). It is copper alloy 122, it cracked a little on the edges. We did not anneal it. It of course is the wrong size.
