Wrapping help

[chrismmaas]

I'm fairly new to rebuilding, and I have some questions about coil heat up lag time. This is my build and set up:

sigelei 20 watt
Fogger v4.1
1.3 ohm (28 ga, 12 wraps per coil, 3mm dia)
vape at 15-17 watts

My coils take up to 5-6 secs to heat up to where you can hear the crackle. Why is that? Too much surface area to heat, not enough power? I'm not much for crazy power to make a choking vape, or chase clouds, but I do like heavy vapor and flovor. Any suggestions?

Yup, you have a lot of coil there,. Try a smaller diameter. 5/64 drill bit, 28g kanthol and 7 wraps = 1.2 ohms

Single coil, less wraps, 2mm, or dual coils with 30AWG and less wraps.
Basically the longer and/or wider the wire, the more time it takes to heat, unless you're pushing some serious wattage through it.

Yeah, you've got a lot of coil there to heat up. Try a single coil... 28g wire, 2mm rod, 8 wraps = ~1.3 ohm

Or if you want the dual coil effect try a sleeper coil build... same thing 28g wire, 2mm rod BUT you wrap two separate coils on the same wire, 4 wraps each with a space between the two coils.

Like this....

I like that, looks awsome.

It works great! Heats up instantly. The extra wire between the coils actually makes that a 1.4 ohm coil.

Here are a few links for you regarding building coils and getting the resistance just where you want it:
1. Steam Engine
2. Coil Toy Calculator

I tried dual 28 gauge coils in my VTR, and even down to 0.7 ohms and 15 watts, 28 gauge just had a lot of lag. 30 gauge performed much better, even a 1.2 ohm dual was OK at 15 watts with 30 gauge.

It's a pain if you have to order some, but I would recommend 30 gauge. It should help.

Thank guys. Using the 'steam engine' coil wrapping calculator and the info you gave me, I see what you mean. I'll get 30AWG and wrap with 5/64 drill bit which is just about 2mm. I'll try 9 wraps per coil which will get me 1ohm and take it from there. Thanks!

Thanks. May be now I could appreciate my Fogger.

Good stuff guys. Picked up some 30awg and now I have instant heat, plumes of vapor and great flavor. Much thanks.

Yeah, I ordered some 30 awg Monday, mainly to rebuild my Kanger coils.
