You don't need two parelled pieces of wire for a swage - it's just a method for connecting two lengths of wire using a metal sleeve. They can be in a loop, which is what I think you are describing, or in line with one another, like this.

The axle on a TCU doesn't rotate - the cam lobes rotate around the axle. The axle is brazed to the u-wire at the terminating point, as you said.

Ah, I stand corrected. Just pulled out a TCU and it was blaringly obvious that the cable is brazed into the axle termination, but the actual TCU looks a bit different than the mental image of a TCU in my head.

yeah, I don't have any at home so I definitely had to stare at google images until it clicked.

No. These are swaged: https://media.wildernessx.com/media/catalog/product/cache/1/small_image/298x/9df78eab33525d08d6e5fb8d27136e95/x/l/xl_copperheads_1.jpg

Nope.
Tech Friends  definitely have swage.  Aliens, Totems, TCUs have BRAZES.  

You might be right, but I have an ~1990 tech friend with a brazed cable (no swage). You can also see a bit of brazing material on the cams here (and a bunch more broken tech friends),

My quick google foo tells me that FLEXIBLE FRIENDS had brazing until 1989 when they moved over to swaging.  All Tech Friends (with the plastic sleeve) have been swaged.
