I've been playing with this for a while and decided to post a little tutorial for others. I originally did this just as an experiment to see if it was possible, but then found it to be the best flavour build I've tried yet on a tank. This may work in some other tanks, but the way leads are trapped in the Subtank does make it pretty easy on this deck.

First you start by building your coils. I actually prefer to make the stovetops with ribbon wire, but you can do this with round wire as well. Unlike making a stovetop for an RDA you want the leads coming off pretty close to parallel with the coil, not perpendicular.

This is a 5 wrap coil around a 1/16th screwdriver using 0.5x.01 nichrome80 ribbon wire.

Once you have made 2 of these coils you want to loosely trap them under the posts with the coil positioned so the top lead is closer.

Next take your tweezers and gently lift the coil up and in.

Tighten your connections at the posts the rest of the way and clip your leads.

Using your tweezers again bend the inner lead towards the middle of the deck. This stops issues with shorts.

Pulse the build a few times at low voltage and tweeze the coils to get the wraps as lined up with each other as possible.

Put the barrel on the deck and you see how little room these coils take up in the end. Lots of room for wicking on each side and nothing in the way of airflow except those two inner leads.

Speaking of wicking I only use about a dime sized piece of really fluffed out cotton on each side. poke it in the deck and fluff it out like so.

After juicing up the wicks pull them in a little bit at the top so you can see a little light from the feed holes on each side. If you don't do this it can cause the wick to not keep up and you burn the cotton.

Finish assembly and enjoy. I usually break these coils in at a pretty low voltage (2.5-2.7 volts) for 10-15 pulls before ramping up to 3.7-3.9 volts. Enjoy!
