my No-fun-Kayfun 3.1es evening

[Wagonator]

so .. yeah

need some advice guys and Gals
The info: kayfun 3.1 ES from Angelcig.com
.32 Kanthal 1.6-1.8 ohm build ( still new to coil building)
Nemesis clone with sony vtc4 batteries


the issues the bottom of the screws are rounded causing the Kanthal to slip out when tightening down doing a standard type coil with the legs wrapped around the posts.

positive post is a little twisted but the unit isn't shorted .. don't really see an issue there other than cosmetic i guess


so i figured i would run it with the legs trapped no shorts and 1.6ish ohms but as soon as i went to testhe 1st time i got some smoke from the air feeds on the nemesis. stopped immediately and rechecked for a short, even pulled the coil and tore it apart checking continuity and for shorts and found nothing.


ive used the nemesis clone before and had no issues. the kayfun was completely disassembled and well scrubbed.

another little issue is when i try trapping the wire the end of the screws are sharp and cut the leg of the coil clear off


are these common issues with the clones or should i start the rma process or just bite the bullet and get another kayfun

I would return it if you can. Even if it doesn't have some kind of an internal short, the juice channels are way too shallow. The whole thing is probably a dud, hopefully all of angel cigs products aren't this poor quality.

+1 for cloudZ thoughts. It really sucks to have to deal with this kind of thing when it happens. Just take a deep breath and resign yourself to it. It has to be done, return it It happens to me at least once a month, this stuff coming out of china is a real crapshoot. With a capital CRAP. Looks like you have most people beat as far as your experience with these types of devices is concerned I think. You definitely know what your doing. That's one nice looking coil! My latest adventure on the bay turned real ugly with a Kayfun purchase. My best advise is to return it and get the Hcigar Kayfun 3.1. I now have several different clones and the Hcigar is made VERY well. Some good deals on the bay right now because of the intense competition.

many thanks .. that was my absolutely 100% first coil i've ever wound. sadly i had to rip it out before i could even fire it

i think i may just keep it for spares and buy one from a local B&M so i can inspect it

First coil you built? And it turned out like that? Whoa, my friend you easily have a knack for this stuff. WOW, I can't wait to see some of your builds coming up here in the near future. Just remember! I discovered you, I want a percentage of all the royalties you are going to start generating once your name is in lights!

Enjoy!

Just my opinion, of course, but I don't see anything wrong with it. The 3.1 base can be completely disassembled for inspection and cleaning if you suspect a short.

Test the resistance of it with no coil installed. If it reads non (---), it's not shorted.

The round screw heads are a pain. I have a 3.1 like that. (I'm vaping on it as I type) The wires can be trapped with little problem if you wrap your leads around the screws once clockwise.

Stop... get your self an ohm meter before you even think about putting it on a mod.....

Read the kayfun threads watch a couple of video's. Looking at your pictures nothing wrong with your clone. The positive block just needs to be adjusted. If your coil was touching the base it would be a short (ohm meter would have shown you that)

Round heads... install your coil so the wire wraps in the direction the screws go... problem solved

yes i saw that when i disassembled it for initial cleaning and i tested it bare and had no shorts but i am thinking there is a spot of poor contact possibly heating up when power is supplied hence the smoke from the air feeds

thank you for this. i had read somewhere to not wrap clockwise due to it pulling on the coil as you tighten. didn't really make too much sense but i hadn't gotten around to dispelling that myth yet. you've done that for me

thank you .. i use my rather expensive multimeter i use daily at work i should have mentioned that in my 1st post sorry

i have no intentions of venting my batteries in my face


good to have confirmation and i'll tear it down again and reinspect the insulator and adjust the positive post

just keep in the drill bit as you tighten the screw heads and it wont bend as you tighten so clockwise is fine. juice channels look fine so im thinking its not a dud.

If you decide not to try to return it, you can get a Kayfun rebuild kit from Fat Daddy Vapes. It will include all the screws and orings, but the positive and negative post decks are sold separately.

 

[<KDM>]

Hard to tell from the picture but where the coil wire comes off the negative side looks very close to the positive block. Test continuity at the 510 connection, that will show if there is a short on any part of your Atty. Get a good set of needle nose tweezers, use them to hold the wire after doing a half wrap on the screws.

.32 Kanthal 1.6-1.8 ohm build ( still new to coil building)
Nemesis clone with sony vtc4 batteries

All the above looks good, decent choices. I prefer 28 awg, 32 is to thin and springy to work with and would give me way to much resistance for my builds.

so .. yeah the issues

the bottom of the screws are rounded causing the Kanthal to slip out when tightening down doing a standard type coil with the legs wrapped around the posts.

I like using the mounting holes also, but opt to put both coil legs through the same side holes, then bend the coil up and over the air intake. Leave the screw just snug, so if you didn't judge the length correctly you can fix it easily, once at the proper height, tighten well, but screw can cut through the wire if over tightened.

Um, your air stem locking collar is loose. Unscrew the 510 center pin, collar will likely unscrew with it if loose, unscrew the base cover cap, you should see a thread collar that threads onto the air stem which screws into one of the mounting blocks. I use needle nose pliers to hold the mounting block in position, the use a larege flat head screw driver to tighten collar. Make sure the block is aligned properly once tight. Then screw cover cap back on, then the center pin, good to build now. No shorts.

no shorts and 1.6ish ohms but as soon as i went to testhe 1st time i got some smoke from the air feeds on the nemesis. stopped immediately and rechecked for a short, even pulled the coil and tore it apart checking continuity and for shorts and found nothing.

ive used the nemesis clone before and had no issues. the kayfun was completely disassembled and well scrubbed.

Using thicker wire will not cut as easily, you can also remove the screws and file the points off. Quality Control is always an issue with clone, but looks like your issues are easily fixable. Also you may want to check out the Micro Coil thread, great method for building and becoming competent. Also swing by the Vcore Build thread, where some have built this puppy with vertical mounted coils.

You appear to be well situated to excel in the rba way, just need time and practice. Understanding everything takes some doing, learning and relearning. Process never ends, but the vape always improves. Good luck, you are on the right path, but Authentic gear is always the best value and the best vape, in the long run. Just saying!!


Vape long and prosper.!!!


Will try a check this thread again to see how you are coming along. If needed, you can pm me, and will get back to you when able.

Rounded screws - most china KF have these. Learning to wrap wire in direction or turn, almost a full circle, and NOT over tightening - will resolve this issue. Also ordering Alan Head - M1.6 x 3mm screws off ebay would work.

Positive post - loosen center shaft, set and hold Positive block while tightening. They all can swivel out of place.

Smoke out the Nemesis Air intake holes - Definitely not an internal issue with the KF. Likely dirty 510 threading or center pin not properly secured. Power in on center pin, ground out on 510 threading and(if set Flush) base of KF.
Possibly water vapor from cleaning

OK UPDATES!!!!!!!!!!!!!!


yeah so i found my intermittent short ( hence the smoke) it was the center pin on the kayfun. the head of the screw is slightly off center and the insulator isnt a full sleeve so it got close enough that when i mounted it on the mod it would just shift enough to short.
a little sandpaper cured that.

6 wraps of 28 gauge k1 1/4" 1.5 Ω contact coil and i think .. not enough wick

didnt take a pic before i semi-filled the tank but i'm sure i'll have it apart before bed tonight lol

 

[dice57]

Hey Wag, sounds you are progressing nicely, and on your way. 1/4" dia coil? Sounds a bit large, but if works fine, I prefer a micro.

Wicking density is the old play with and vape and vape technique, to get down. lol. I twist up a strand of cotton tight, so it pulls easily through coil with little to no resistance, then untwist to fluff up wick inside of coil.

Once everything is in place, fold the tails up an secure the containment ring. Once ring is tight, tuck the tails into the juice decks, This will keep stands of wick getting caught in the threads, which can clog the juice channels.
