Wanting to do a micro coil setup with my RDA BUT, only have 32 gauge kanthal.

[TheReign]

Just gonna give it a shot for Giggles so i'm going to try to muster up a quad micro coil out of this 32Ga

Anyone have anyone ideas for amounts of wraps???

Are you using batteries that can take low ohms without blowing up in your face? Do you know how to tell? If not let me know and I'll help ya with it

i highly recommend you know what you're doing with this. If you make a quad and each coil is two ohms you'll be pulling around 8 amps

I will save the speech about safety, you will get plenty of that from others. Using a 1/16th drill bit I did 8 or 9 wraps to get 1.8-2.0 ohms. The length of your legs will affect this a little. I would say start with 4 coils of 9 wraps each and see how it is when mounted and fired. Just a note if you don't have an ohm meter at the least don't even try it. With 4 coils you should hit around .5-.6 ohm .5 ohm will get you 8.4 amps with a fully charged battery (4.2 volt) .6 ohm takes it to 7 amps of course as the battery discharges the amps go down. You need to have a battery rated for at least 15 amps if not 20. Personally I bought 30 amp mnke just because they didn't cost a ton more than batteries rated at 10 amps. I would rather be safe than sore.

If you twist two strands of 32ga (by hand or with a drill) to around 16-20 twists per inch, you will effectively cut the resistance by half (1.1Ω per inch to roughly 0.50Ω per inch) - then you can build a "2X32ga" single or dual coil with equivalent resistance of using 28/29 gauge wire.

Twisting the wire will increase surface area (vs. an equivalent resistance single wire), make it stiffer, less prone to distortion and provide rapid heat times.

No problem at all.











<-- that is a 5/6 wrap 2.2 ohm 32ga micro coil.

Actually, twisting wire will give you more than one-half of the equivalent length of straight wire. Because the wire is twisted, each strand is longer than the finished twisted wire. And the tighter you twist the wires, the resistance will increase.

With a very tightly-twisted pair of wires, I wouldn't be surprised if the final resistance is two-thirds, possibly even three-quarters of the resistance of a single wire of the same length.
