New Member Question: Subohming Kayfun Lite on Sigelei 20W

[Kevco]

Hi all, first post here after lurking a while. I have some experience building coils and recently acquired a Kayfun Lite clone by Tobeco. I vaped it for two weeks on my Sigelei 20W with the high resistance premade silica wicked coils it came with at about 2.3 ohms. Pretty good stuff but didn't wick fast enough for my tastes. I had some kanthal at home but only 26 gauge. I made a couple of micro coils but the highest resistance I could manage and still keep the coil small enough for the Kayfun was about .73 ohms at about 12 turns on an eyeglass screwdriver. I have some 28 gauge kanthal on order but until it comes does anybody see issue with me vaping this on my Sigelei? I'm hitting at about 17W, cotton wick, huge flavor, nice clouds. I plan on building to about 1.2 ohm as soon as my 28 gauge arrives in a couple of days. Will my insulators survive until then? The Kayfun gets a bit warm if I chain vape but nothing crazy. Any thoughts appreciated here. Thanks in advance!

I have run my Segelei 20W with a dual coil build at .8 ohms with no issue other than the battery drains pretty fast. My normal builds are 28 awg at 1.2 to 1.4 ohms for my Kayfuns. When I want to sub ohm I use either my Fogger V4 or AGA T7 on an SX 350 or DNA 30 with dual batteries.

I'm not sure how low you can go in a Kayfun before you melt the insulator. It's common knowledge to use the Kayfun between 1.0 - 2.0 ohms, which is its sweet spot.

I'm currently using a 1.3 - 1.5 ohm microcoil in my KFL+ using organic cotton. I'm currently using a little less cotton than is shown in the below pics.

My goto Kayfun build is 28 guage with 7 wraps around a 5/64 drill bit and runs at 1.2 ohms about every time.

Now I switched to cellucotton and enjoying the KFL more now.

I use .7 to .8 in Kayfuns regularly without melting the insulator. .6ohm is where it becomes a little too hot on a mech and I've had to replace the insulator after it melted. When I rebuild next I might try to hit more around .9 thought .8 seems to be my preference for going between mechs and vv mods.

I should meantion I use twisted 28 micro coil.

I've built some coils .7-.8 on my Kayfun and Russian 91% without any problems but like Baditude mentioned they seem to work better above 1.0. My builds now are mainly 1.2 or 1.3 and the difference to me is much better flavor and smoother vape.

Exact same build 7 wraps 5/64 bit 1.1-1.2ohms Everytime it is my sweet spot for Kayfun! I did run .8 ohm coil once for about a week and did not melt the insulator. It was to "hot" for me but again did not melt insulator.

Nice thanks all!
What's the lean on cellucotton? I haven't heard of that...

I switched from organic cotton to cellucotton (rayon) about a month ago and I haven't looked back. Cellucotton is the brand name of the rayon. I got mine from Sallys, a beauty store.
