Kayfun/Russian wick setup that works great for me.

[LReyes66]

Rewicked it cause I had free time even though the wick was just a couple of days old n going good still. I just love madrina suicide bunny juice I wanted a fresh wick for it LOL. I think one side of the wick was thicker though with cotton then the other so I don't think it was as good of a wick job as last. Think ima wait til Truman posts the pic up to redo it again

I got my R91 clone a few days ago. i had a successful 1st build using the OPs method, i changed a couple things.
I wrapped 28g 5-7 times around an rda screwdriver to get 1.1ohm MC. cotton ball wick, balled up to add chimney, and pressed down below by the channels.
(the modification)
i added a small pinch of rolled cotton above the well (above the wicks), almost level with the coil. this is to keep the feeding wick wet and helps with chain vaping.

it adds similar benefit to the truman wick method mentioned in this thread, but doesnt cover the top of the coil restricting any airflow, and greatly benefits wicking. havent had an issue yet.

i recommend tryin it, its really simple

Thanks I'll give it a try. Gonna have to make a new coil since mine is currently diagonal on the base... So u haven't had it broken in yet?

Glad you got a setup running well. Some of my first builds I was doing were similar to your method. I did try a couple small tufts of cotton near the coil to aid feeding. It seemed to work well.

I did just wrap a fresh coil in my 91%.
The one in my pics had been in it for quite a while at the time the pictures were taken. So at this point, I wanna say that coil was in use for almost a month.

I just did 11 wraps of 28ga around a 1.7mm post, it comes out to around 1.35ohms.
I was aiming to go a little higher than usual because I've been testing a diy bakery juice that is pretty heavy on cinnamon danish.
The last time I vaped that juice was on a .7ohm coil. A little hot for the cin danish flavor, and it blew out my taste buds. After about a week of revision testing I couldn't taste anything. Had serious vapers tongue.

I keep wanting to try new coils and wick methods, such as trumans wick. But the setup I'm using is so bullet proof and simple, I can't bring myself to change anything. Creature of habit I guess.

I may take one of my kfl clones and modify the juice channels to work sort of like the Squape atty does.
If you're not familiar with it, the wick lays in the juice channels, completely.
It would be pretty easy to do, and if I destroy it, I'd be out like 20 bux.
Worth it in the name of science!

I followed this method (more or less) and got really good results, thanks!

A couple questions; three days after my first build, I decided to try another with a diff wire gauge. The coil, and the cotton around the coil, were gunked up and almost black (though no problems with taste with the final tank before rebuilding). I know this must be juice dependent to some extent -- I was using a dark e-liquid called Vader Pudding from MLV in Toronto -- but is it normal to see this kind of build get so gunked up? I haven't used cotton before.

For my rebuild, I was in a big hurry, and used more cotton than I should have (i.e. with more time, I would have redone the cotton, and used less). When I vaped this new build, the taste and TH were excellent, but vapor production seemed light. Could this lesser vapor be connected to excessive cotton?

Thanks!

I am using CVS sterile cotton, which has a tendency to pull apart if you use too much.
I have found the perfect amount is when it starts to bunch up a hair on one side of the coil, but not break. It creates a small shoulder on one side of the coil, as you can see in the pic.



I trim the cotton so it is about the width of the base of the atty, as seen above. The picture makes it look bigger than that, but it is about 22mm wide.

Just wanted to say thanks to the OP and everyone who's contributed. I've been having a hard time with my build but I'll be following this guide as soon as I get a chance.

I'm thinking that it was juice dependent. Possibly too much cotton may not have helped since it possibly wasn't wicking fast enough. But most likely the juice.
Also, vapor production can suffer from using too much wick. Since the juice can't get through the coil fast enough, there is less of it to atomize. Hence less vapor.
Glad you had decent results. Try using a little less cotton. Flavor and vapor will increase quite a bit.
Also, pay attention to how high your coil is above the airhole. Between 1-1.5mm seems to work well for me. You can see in the pics the space between the coil and deck.
Edit: I haven't actually measured the coil/airhole spacing. Could be as much as 2mm. In my pic I'm guessing it is about 1.5mm.

Thanks for the reply. I'm going to redo the cotton when I get home tonite.

I've been using this method for about a week Reyes, be patient with it, it takes a minute to break in and come up to full flavor and vapor production, this is typically the case with any cotton build.

Thanks I'll give it a try. Gonna have to make a new coil since mine is currently diagonal on the base... So u haven't had it broken in yet?

I'll try it again when I can twist my 30g since I ran out of pretwisted wire. Til then I just did a nano coil with 28g on12-13 wraps with your previous wicking method since I was still having flawless performance before I decided to do a different coil. Had to lower the coil then how high I had it on my last coil to compensate for a smaller diameter coil lol

Looking good Reyes…nice work.

 

[Glenn_K]

Nice looking build, but any reason in particular why you leave the cotton so long, and fold it back onto the coil? Have you found that doing it this way improves the performance?

This method improves performance in all areas Glenn, more wick on coil produces more vapor and flavor, and the extra length of the wick holds more liquid, so no dry hits if built properly.

Nice! With the dark e-liquid I've been vaping, i'll be changing cotton soon, and will have to give this a try.

 

[LReyes66]

yup. Even when my tank is empty i can take an extra 5-6 hits before it starts getting dry

I got Truman's top wrap wick set up perfected I think. I wanted to give it a few days to see if it remained solid and consistent. I'm going to say that right now it is the best set up I have gotten out of my Russian, and that is not a comment to be taken lightly... it is the best performance of everything I have tried. I can't really find anything wrong at all. Nice clouds (which I honestly don't care about), a beautiful flavor with no dry hits (which is everything to me), long lasting, no flooding (although I did play with my airflow a bit).

Originally I was getting dry hits. I tried using less cotton and still got them. I actually found that I was using too little cotton though the coil. Also, instead of stuffing my ends down into the opposite well (loosely of course), I stuffed it between the coil and screw posts and terminated it there.

I have gone from lower wattage set ups to 9.1 watts. So even pushing it (from my perspective) I have no ill effects.

Thanks for sharing, Truman. I am completely impressed.

FWIW I have tried chimneys and various other wick and coil configs, but each coil and wick setup suffered from one or many issues including; lack of vapor, too much throat hit, too little flavor, dry wicks, flooding or gurgling.

 

[LReyes66]

Which one did u do? His previous method or newer one?

[LReyes66]

Did it with the new method. It took my longer then expected because I was trying to adjust the strand that lays over the coil n was paranoid it was gonna move out of place if moved around after filling

Wow, folding an extra long cotton wick back on top of the coil really makes a diff, awesome suggestion. This has given me my best KF (clone) vape to date. Thanks for the thread!

(Now if only I can find someone who can explain how to get good results with my genny )
