Ok so people told me i need to be safe cause i wanted to go from a 50watt mod and subohm to a rda hero cloud chasing hero, so i bought this
  • 2 x Sony 18650 VTC4 2100 mAh 30A Battery *AUTHENTIC*
  • 1 x Efest Luc V4 Battery Charger
  • 3 x Japanese Organic Cotton (8 Pads)
  • 1 x sigelei 150w Box Mod
    (Color: Black)
  • 1 x Ohm Meter
  • 2 x Spooled Kanthal (Multiple Gauges) 24g and 28g
    (Gauge: 0.30mm,10m/roll,28 AGW)
  • 1x Mutation X V3 by Indulgence
  • 1x 1.4mm,3mm,2.4mm,2mm, phillpsheads
What i need to know is can someone tell me which of those phillps heads to use, and which wire and how many wraps so i can sub ohm about 0.3 on dual coils and cloud the world.

Most of us use the Steam Engine | free vaping calculators coil building calculator.

Since your question is about which diameter to build at, select your wire gauge, type of build (single coil, dual coil, etc), and target resistance. You can then start entering different coil diameter values until you get to the number of wraps that you prefer.

You don't need to build that low with a Sigelei. But if you do, use 24g with 6-7 wraps per coil using your 3mm screwdriver, or 7-8 wraps per coil around your 2.4mm screwdriver.

With 28g you'll need half the wraps of 24g to get about the same .3ohms.
also what wattage should i start at if i do 2 coils at the 7 wraps at 24g

I suggest learning to build a single coil that's not sub ohm first. Why waste time building two bad coils at a time. Positioning, airflow etc all make a big difference so experiment with that first. When you begin sub ohm, especially bellow .5 in my experience, it becomes a different technique. The high powered cloud chasing concept takes much more skill, willingness to learn and patience than most people realize. To answer your question more specifically I prefer twisted 28g, parallel coils with 9 wraps each around a 3/32 gives me .5 so I estimate 7 wraps would give you about the desired .3 Also I advocate not using any calculator apps, do stuff the hard way, learn it and it becomes intuitive.

Just on a side note...all that for $170? Good job.

On the steam engine site go to ohms law tab and put in your resistance then for voltage I usually say to put in 3.7v , then see what watts comes out.
For say 0.5Ω that would be around 27 watts. So start from there. The watts will be different depending on the resistance you put in.
Probably need to start going up from there on that atty but its a good place to start.
