protank coil build question

[honeycombdome]

I'm starting off with building coils on my protank 2 mini to get a feel for it. I've watched RiP Trippers video on youtube and he suggests doing 12 wraps with 28ga. kanthal for a microcoil, can anyone tell me how this would translate for 32 ga. wire and if I can expect the same amount of resistance? I'm primarily using my zmax v5 at around 4 volts or 7-8 watts so I'm thinking around 1.8-2.0 ohms should work okay,is this correct?

thanks

5 wraps of 32 on a toothpick puts me right at 2 ohms.

Type in your desired resistance and the gauge wire you are using.

Happy vaping

For 32gauge, 8 - 9 wraps should give you 1.8 - 2.0 ohms you are looking for.
32gauge = ~ 0.21 or 0.22 ohms per wrap on 1/16" drill bit. 2.0 Ohms / 0.22 ohms per wrap = 9 wraps
Using same formula, 8 wraps would give you ~1.8 ohms

thanks guys

will these figures vary much depending on wick material?

Yup. That's pretty much what I get as well.

8-9 wraps of .30 gauge perhaps? 7 wraps of .32 puts me in the 2.5 range for a protank coil. Haven't even tried 8-9 wraps.

Depending on the size of the drill bit you wrap on. At the end, it is the length of the coil that counts. 1/16" drill bit is smaller than a toothpick. So, number of wraps would be less. Anyway, these are just estimates and posted them just to give some idea/reference point.

Lot of times, new builders don't think of final resistance output being something they can actually calculate. Trying to infuse a bit of basic math.

Not that I have seen. Depending on the juice type you use, you might see a slight bump after coil gets "burned-in".

I insert the end of a paperclip into 2mm hollow Ekowool wick, and do 6 wraps of .32 Kanthal. I get 2.4 to 2.5 every time. Coils perform better, and outlast stock.
