KFL+, 1 mm, 32ga coil didn't work well

Worked great at first, but after a few vapes it burnt quickly when inhaling.

Not room for much cotton in a so tiny coil. Maybe not optimal for the KFL+?

Recommend you step up to 2mm and reduce the number of wraps.

I agree with the bigger diameter coil. That's pretty small.

.8 to1.4 ohms at 2-2.5 mm's.....Much bigger and it gets hot.


with cotton "more is better."

Thanks. Rip Trippers is using even smaller ones for his double barrel build. 1/32. Less wraps as I can remember. I hope it will work fine.

As you found out ... You just can't put much cotton in a very narrow coil.

For my kayfun, I use either Silica or cotton yarn for the wick. Since I pull a double piece of this through the coil, I make the coil on a 7/64" (2.8mm) drill bit.

Also, I find 28 AWG Kanthal easy to work with .... I think 30 or 32 gauge is just too thin.

One other thing ... silica wick can be dry burned, whereas cotton cannot, and I don't like replacing cotton wicks every couple of days.

Obviously the wick shown above needs to be cut shorter now that it has been pulled through the coil.

I've found that my kayfuns get dry hits frequently with smaller wire, smaller diameter, and with resistance lower than about 1.2. I've been really happy with 2mm, 1.2 ohm with 28g kanthal with Japanese cotton.

Dual coil on a KFL. 28 gauge, 10 wraps per. 0.9 ohms. works awesome. Used some small hex driver, no idea what the size it. Around 3mm I estimate...

Thanks. Will order silica the next time then.

What diameter silica you using there? Where to you get cotton yarn? So thats coming out around 2 ohms. What are you running it on?
