The coils look really large, So big they are blocking airflow. Also they look to be just about sitting on the deck, also blocking airflow. I would suggest some smaller diameter coils that you can raise up enough so your air intake is located so that its pointing right at the bottom quarter of the coil, leaving room all around the coil for air to get around it.

Have a look at the coil build thread for allot of tips and tricks, :?)
Coil Builds

Have fun, my very first coil promptly got ripped out for another, then another. Its a constant journey. :?)

3 wraps isn't enough surface area to evaporate liquid well. You end up with a hot coil in a tightly focused section of your cotton (or whatever).

Try increasing the wire gauge so you end up with more wraps, at least 5 or more. Keep in mind though, thicker wire will take longer to heat up, it's a trade off.

I generally build in the .6 - .8 range and on a fresh battery (mechanical mod) it ends up in the 18-20 watt range. That works for ME, your mileage may vary...


Just to clarify your post, increasing the number or "gauge" decreases the wire size, I.e. 32 gauge is smaller then 28 gauge.
The higher the gauge, the more resistance. The larger the diameter of the wrap, the more wire used..... Means higher resistance.
A good rule of thumb for you is practice on single coils first. Once you get it down and can consistently get the ohms you want, switch up to duals (if you desire). Building duals half's your ohms.... Two 1 ohm coils becomes .5 ohms etc..
