I have a tool now, but that was just a screwdriver wrap. Just wrap it like a contact coil and pull and stretch it a little at a time. The spacing will almost won't be perfect the first time and then squeeze it all back together and stretch it again. Just repeat and it doesn't take long for one more stretch to come along and it ends up just like this.
Umm.. Yeah... A screwdriver might work, but the other stuff you (& others) mention just has NEVER worked out for me to get nicely spaced coils. No matter what they end up being god-awful misshapen coils from hell.
Although thicker gauge could be a different story, I've only gotten into thicker gauges recently (24 & 22) - and still have a nuclear-holocaust stockpile of various other thinner gauges that I twist. One thing to be said for thicker gauges, is they practically last forever - until I get bored, that is.
It's so bad for me, that if a mod-atty combo doesn't want to work in TC with contact coils, then it will simply end up being a power-mode coil (even if ni-200 or Ti) - end-of-story.
However newer mods seem to be far better with TC (even the Espion Solo). I've gotten a slew of 9 new mods (3 DNA), and so far every single one has been flawless in TC, or almost flawless (temp a bit off compared to others, but still stable). Even with my most temperamental super-springy SS304 wire. Although maybe, just maybe, that could be because I stacked the deck this time -- and ONLY searched out mods known for superb temp control.
IOW - NO SMOK DEVICES anymore!
..... Also of note is that Arctic Fox on my older Joyetech-based devices revitalized them for better TC operation.
Though aside from thicker 22/24 gauge, all of my wires are twisteds. No complex wire yet, but I do currently have several spools of SS316L-only Clapton-esque wire on the slow boat from China.
