Kayfun LITE

[turbocad6]

donnah I've had different builds that winded up on both ends of the curve, from too dry all the way towards too wet and flooding, I think it's more a matter of finding the balance in between, I think too dry is usually caused by too much wick material in the side channels, that kind of seals off the bleed channels and doesn't allow it to "see" as much suction causing less feed. I'd say try to build something with very little tail into the side channels to see if that changes anything for you, I doubt a difference in channel width that you can't even see is going to cause what you are talking about

also as far as a vertical spiting I don't know if it will, a genny does because it is being feed right through the tube but here it would only be feed from outside the coil... I'm going to try one tonight if I get a chance

has anyone played with vertical coils in the kayfun? I think I want to try that next, the inlet hole right below the chimney seems like it would work very good with cotton around the outside of a vertical coil and air passing up through the center

Just with ceramic....I have ground down the legs of the wick and added a loop of cotton over each leg since taking the picture. It's working very nicely now. Sorry it's not a Kayfun....but after tinkering a little bit I think the KFL might should have kept the adjustable air, I have found it nice to dial in juice flow.

yeah, I'm a little leary about not having the airflow adjustment on a device that uses the airflow to create the feed, I use the airflow adjustment all the time to finetune a build, without it the only thing you can vary is the pull of your draw, with it you can adjust it to work the way you want to draw. I ordered a lite but then changed it to the 3.1 instead because I'm just not eager to give up the fine tuning of the needle valve air inlet I guess

Here is a couple of pics of a similar wick in my home brew delrin KFL clone with clear chimney

I learned a lot about the kayfun style design when building and playing with this, the clear chimney helped a lot in seeing the dynamics.

does it spit at all?

I agree 100% and while I would love a kayfun....I'm definitely not complaining about the $95 I spent on The Russian.

Only if your able to fill the coil hole. I haven't had any spitting on my delrin or Russian atty. I have only had spitting in some horizontal genesis wicks and some other vertical trials. The Kayfun style feed regulates the juice so it hasn't been a problem.

that's what I thought. going to try a vertical with cotton on my next build, it just seems like it would be ideal for the way this thing flows straight through

I'll be waiting to hear the results, cotton would be much easier to deal with than the ceramic. Other than the ceramic never really needs replacing, just cleaning after a while.

 

[turbocad6]

perfect would probably be a thin tube of ceramic as the burn surface, and then cotton as the wick from the feed tubes to the ceramic burn surface, sounds just about like what you've done. with a ceramic burn surface the cotton should last a really long time since it could never really get scorched... I need to pick up some ceramic too, I figured it wouldn't be workable and would break and crumble if you tried to work it but I see now that you were able to actually machine it? is it more like a ceramic foam I guess? I just pictured it as more like a porous glass that would crack and shatter

yes and I even have posted pics of them about 10 pages ago. but like I said before today all my previous pics are missing within this thread and I cannot upload any. what I have done is made a single coil(ive done both 28g&26g) after a single coil is made you bend it into two sections. I then mounted vertical in the kay-lite. it is now my regular coil that I use. I believe it performs better. after the coil is mounted I insert one cotton wick per side. the wick is threaded into the coil and both ends are in one side of the juice well. so basically I have 2 ends of wick per side in the k-lite.

I recently stated that I never have leaking issues with the KFL. Well, there is one scenario where I get a fair amount of seepage: dramatic temperature differential. Not terribly unexpected, but lately it's been close to 100 degrees f. out, and when I transition back and forth from air conditioned spaces, to outdoors - probably a 40 degree difference - it leaks a bit out of the breather hole. This is similar to the altitude discussion from earlier, of course. Anyway, it's not a lot of leakage. Enough to be a little messy, but not enough where I feel I'm losing a significant amount of juice.

get the same when I leave the fun in my truck during the day, but after a few vapes its good to go.

It could be that you have exceeded your quota for pic storage, for non-supporting members its not that much. Even as a supporting member I use photobucket. With photobucket you can post more than 5 pics per post and can post much larger and easier to see pics.

I only had about 10 pics stored, but I think your right, probably an issue with storage. will look into the bucket. thanks.

I can see them but I just got up from another nap (I nap a lot LOL) I don't upload to ecf.. I upload my pics to photobucket and then copy and paste the img link

I am really wondering if some of these units have deeper and shallower grooves than others, that might account for some of us who can't seem to get consistent wicking while others can't get it to stop over wicking. I rewicked yesterday and did somethings that I don't normally do... absolutely perfect wicking on this build. No dryness at all. every vape is saturated and awesome. It's nice that I haven't had to do dry draws to get juice into the chamber. But then again I HAVE had a few wicks that wicked perfectly throughout their lifespan.

I don't know.. maybe it's personal LOL

it is very possible about the machining. I often wonder why my builds are perfect while others who appear to do the very same thing have issues. so what did you do slightly different?

that sounds interesting, so it's drawing air across the lengths of the 2 coils I guess?... I guess I could see that giving a bit more surface swept area in the airstream than a horizontal layout but I'm more thinking along the lines of no center wick, the center is for airflow and the coil is lined up with the air inlet and it's feed from the outer side of the coil, the coil itself acting almost as a straw for the airflow, feeding vapor directly into the airstream inside the coil. only thing is with what I'm thinking I may need to use some NR wire to connect the top end of the coil. I have a few different ideas in mind, I'll see what works out for me I guess, the KF mini is pretty tight space wise...

I just got my kf lite delivered today, and after slapping on a quick micro/ cotton I have to admit that I'm pleased with this atomizer. I really look forward to dialing in my wicks and having a similar quality vape that I get with my dripping atty that is more travel friendly. Reading this entire thread during my 2 week wait for this thing has really helped me understand this thing.

although this coil has no wick in it yet I have only done this double vertical, no single.vert2_zps60580e6e.jpg I guess this didn't work, I just set up the photobucket and copied and pasted but I think I missed something, will try again. with the double coil the wicks are a little out of the way of the airstream. the air hits both coils right in the center . will try agiain to post a few pics

Yeah, I welded some NR wire for the long connection.
