For the record, I learned how to build coils on Vivi Nova's first, then on a Phoenix A7 Clone.
Building a coil for the Protanks, EVOD's, Kanger T3's, Vivi Nova's, etc. is actually very easy.
I used this video....

So, the only thing you really need to know is, what Resistance (OHM) you are wanting.
this will determine what kind of vape you get.
Using the first video with a 4/40 screw I aim for 2.5Ohm using 32ga Kanthal with a 6/5 or 7/6 wrap
That is 6 lines on top, 5 on the bottom of wrapping
I generally vape at 3.7v on my Provari.
You will have to experiment to find what you like.
The cheapest place for Kanthal is TemCO
Kanthal Wire 32 Gauge RW0097 - 100 FT 0.25oz Series A-1 Resistance AWG
You will need to search around for good Silica, not all places sell good Silica.
as in, it might be frayed, or just trash with some salvageable.
Same with Kanthal, which is why I only buy from TemCo anymore.
Too many vendors wrap wire around cards, or cardboard, and it sucks.
You want spooled wire only.
You can generally use 30ga or 32ga some use as low as 28ga (i don't recommend that), I generally stick with 32ga
You will need to get an ohm meter,,,
Cartomizer and Atomizer Ohm Meter - Meters - Accessories
or
Rechargeable OHM Meter
I have the first one.
You may need to get an adapter for the Kanger to 510 connection.
510 to eGo Adapter - Adapters - Accessories
Hope this helps a bit more.
PS. The first video he uses a Beading threader, I made one out of a long piece of Kanthal doubled over, with a loop at one end, and twisted together, doesn't take long to build, and if you lose it, no big deal, make another.
