I didn't realize people struggled that much making R+NR coils. The only tool I use is scissors, and I don't often have to trim off excess wire or wick. Here's how I do it:
Leaving the res and non-res wire on their spools, pinch the ends under your thumbnail leaving about 1/2 inch exposed.
Twist the wires about 5 - 7 half-turns, until the length of the twist is longer than the length of the untwisted ends.
Now fold the untwisted ends back on top of the twist.
Up until now you've been holding the R and NR wire under your thumb, both wires going backward. Now, bend the NR wire forward and wrap it around the twist and bent-back tips a few times to secure the joint.
At this point, it's finally time to cut the wires. For a Penelope / Euforia, cut your NR wire about 1 1/2 inches long. For an Ody / Term, about 2 inches. For your res wire, you probably know better than I what length you like. Be sure to leave an extra 1/2 inch on your res wire to repeat the above process to complete your coil.
I'm making this coil for a Penelope using 34 gauge res wire. To get about a 2 ohm coil, I need about 1/2 inch of res wire + 1/2 inch for the second R+NR joint. You'll notice that my non-res wire is about 1 1/2 inches, and my res wire is about an inch.
After repeating the process to complete the assembled wire, I end up with a nice little 3-turn-over-2 coil for my Penelope. This one will probably meter about 1.8 ohms. I usually go for about 2 ohms, but taking pictures while building was an unfamiliar obstacle.
My positive NR wire is about 1 1/2 inches, and the negative is about an inch. I'll probably either have to break off a quarter inch of the negative end after assembly, or just run the extra along the threads. There should be no extra for the positive, and it's not crucial whether the wick reaches the bottom o-ring or even the bottoms of the ceramic assembly channels. It doesn't take long before you can eyeball measure the appropriate lengths and get close enough on every attempt.
