Two good wire joining wrap techniques I found on Tumblr. One's the red set, one's the blue set, sorry they're interleaved it was a gif. But they're definitely going into my how-to-wrap-wire brain toolkit.
Scenario
KazinatorThe blue one looks like a Western Union splice.

When you just twist ends of a wire together, that's called a rat-tail joint.
@Kazinator Oh, it has a name! Neat ^_^
Roger Crew✅❌☑🗸❎✖✓✔Hm. Not clear what the final step is for the red wires. If there's just a single bend in the left wire or the end is just getting snipped off, that looks like it would pull apart really easily under tension
HTTP 1.1/418 Teapot@wrog @moira Actually, I'm not sure - I learned to call basically any of the "take the ropes and tie knots around each other and pull taut" types as "fisherman's knots." Telegraphy makes sense as well, though, since you're going to have sustained (and expected) tension on the two lines as well. Speaking of knots, I dropped a bookmark for this into pinboard and it turns out the site's still good.

@wrog the end that sticks out gets bent over and back up, forming a very tall U and keeping the coil form sliding off.
In _my_ case what i actually intend to do is the red knot, then solder it because I'm like that, so it'll go nowhere ever. and the reason i'm caring about this is because i want my soldered-together connectors not to be lumpy. it bothers me. #picky
