Hi All

What’s a nice way to finish (say) a free 12” run of just two cores of 22awg wire? For instance to the bulb of a flight instrument.

Try putting the search term “wire wrap braid” into eBay. The stuff comes in myriad colors and diameters at minimal cost.

I was going to suggest that too . . . I use
a drill motor to create lengths of twisted
pairs for later incorporation into a project.

You can capture on end of the pair in
a vise; the other end in your drill
chuck. Run the drill until you get about
1/2" per turn pitch on the twisted
assembly. Release the rotary tension
carefully . . . some wires will react
rather amazingly to become a snarled
tangle if allowed to freely 'relax'.

If your drill runs both directions,
you can drive it 'backwards' enough
to reduce the rotary tension before
you take it out of the chuck.

I've fabricated twisted pairs of 10 feet or
more with this method.

If you do this with all your wires, invest in multicolored wire. If you've got runs to three different devices, each with a ground, you can have white/black, green/black, and red/black. It isn't absolutely necessary for functionality, but when it comes time to troubleshooting/adding/removing/replacing devices, you'll love it.
Also, if you have four spools of wire, build a box with a rod through it and hang the spools side by side. Then you can spin them together as Bob suggests straight from the spools, and spin off exactly the length you need each time.

that works . . . someone also
reminded me that I've suggested
shielded wire for things like
compass lights, etc.

use shield for one side, center
conductor for the other.
