Cutoff is at 0.8 I believe- mine will fire at 0.8 anyway- I've read where people have for them to fire down at 0.7 but haven't had the chance to try mine that low. I try and stay between 0.9 and 1.1 dual coil
my condolences bronze.There has been every conceivable kayfun build attempted and reported on this thread. I tried something a little different and want to chronicle it in this thread as a contribution to the vast knowledge gained and shared with my fellow Kayfunners past, current, and future.. I wanted to see how long I could make a coil last. To refresh, my coil is a 30ga, 10 wrap, 2.0mm (5/64ths) ID coil. I've used primarily silica wick but have also run cotton as well. I built this coil on December 1, 2013 and it is with great sadness that I announce I had to euthanize it tonight. There were two reasons. The primary reason was that it was no longer glowing from inside out as it had been to this point. The glow started on one side and worked its way to the other end. Efforts to re-crimp and repair went without reward. The second reason is I'm getting resistance creep. The coil started as a 2.0ohm coil and it is now worked its way up to 2.4ohms. I'm sure I could get continued use out of this coil, but decided to retire it to the stud farm because building a new coil is essentially effortless, inexpensive, and why settle for anything less than perfect?
Anyhow, thought you'd be interested. Very few people use a coil till the end of its useful life so I wanted to get it chronicled.
Coil
December 1, 2013 - May 23, 2014
Rest in Peace.
Triple twisted 32g 9/10 wrap coil, measured in at 1.6 ohms... Running at 4.5v.
I did an angled coil this time around and went with a S shaped cotton wick.
Massive flavour and vapour, although it almost seems to be begging for more power. A LOT MORE!
I believe that silica is easier to build and to get right. one really just has to wrap some kanthal around the silica and it works, if using silica it is not as crucial to get the proper tension around it compared to cotton. cotton is soft and is a bit more tricky to get the proper tension of the kanthal. if one has the kanthal too tight it just doesn't work that well, if its too loose, same thing. cotton expands, which also adds to the equation of proper amounts. either way though, both wicking materials really produce the same results so whatever works for you is the material one should use.I tried cottons and it just didn't work for me. Silica is what works great for me. I keep trying 1,2,3 and 3.5mm silica and they all work. I'm currently using doubled 2mm silica and loving it. With 30g kanthal 5/6 wraps at 1.8Ω with 100% PG.
I do this to some extent, bearing in mind that I don't have a torch, I have a lighter; however, I'm a little bit leery of applying too much flame, because once I apparently applied so much that the wire just broke. Of course, that was 32ga, and I use 30ga with the KFL+, so maybe not as much of an issue. That 32ga is so fine, it gets brittle very quickly.
But since I do use 30ga with the kayfun, I may try a little more flame using the needle-nose to hold it *gently* while I flame it, and maybe not need to work so hard at compressing it after it's mounted.
I also informed my husband last night that what I *really* need are some ceramic-tipped tweezers, so I can hold it *while* I press the fire button; they're kinda pricey at $14-ish, but I'm thinking entirely worth it. Especially when I start working more with the 28ga I just got, because that wire is thick enough to be really stubborn, so pressure while firing would be really useful.
Thx!

I've used both; I only switched because I was having problems learnin to wrap coils and someone at a b&m was cool enough to show me on one of
My kfls he wicked it with cotton and after I saw how easy it Was to thread compared to
Silica I was hooked- albeit if not wicked right and the cotton burns it tasted like used toilet paper.
Sorry but Sterile Cotton is Sterile Cotton to my taste buds. I'll just stick with CVS or WalGreens. No waiting, and If it can be used when I cut myself (again), then it's good enough for me.
Now if I can only get my darn arm to stop bleeding.![]()
that's why I use cotton myself, I just find it a lot easier. im always messing with builds, I probably have close to a hundred coils in a container that can snap onto my kayfun in a second. so I just snap on a coil and thread it with cotton. you simply cannot do that with silica as easily. to me it just seems like a micro coil & cotton has a lot more options.
Huh? I didn't know anyone wraps wire around cotton. Most people (myself included) make a coil, install it in the atomizer, and then wick it with cotton. When it gets a little funky, pull the old cotton out, dry-burn the empty coil, and put new cotton in it.cotton is soft and is a bit more tricky to get the proper tension of the kanthal. if one has the kanthal too tight it just doesn't work that well, if its too loose, same thing.
Thought I was the only one- got bored the other night and decided to start wrapping

The tricky part is getting the amount of cotton in the coil just right. This is where a consistent pad like a Koh Gen Do makes life easier than generic cotton balls do; I find it much easier cut strips that are always the same size and produce consistent wicks from such a pad than from any other form of cotton that I've tried.
I simply don't understand the obsession with 28 guage. I wrap everything in 30 guage and depending on ID and size. Heck I can go from 0.3 up to over 2 ohms. Torch and wrap. But then I cheat and use a coil winder. (wish I had a pic of it). I got it off Ebay. Not to much cash. Oh heck I'll go find the darn thing. BRB.
here it is.

Just get the complete set. Comes with 1 mm, 1.5mm 3mm, and something huge. I used a wire coat hanger to get my 2mm, wraps. Easy as pie.
(Even for a one eyed blind man).
agreed for sure. the slight differences I see are mainly how different coil designs handle higher wattages. watt for watt I have found one coil design to be not that much different to another.I haven't built as many different versions as you Diver, but I've built maybe ten different ones...gauge, wraps, ID's, silica, cotton, etc.. Truthfully, if there is a difference in performance I wasn't able to detect it.

To me, the biggest difference in coil design/performance are those used for subohming in a mech Vs using a 1.5 - 2.0 ohm in a regulated mod.
