Rayon wick, better flow, flavor, saturation and Nic Hit!

[Fisheeboy]

So my second attempt at using the rayon in my Russian is going great. I can pull up to 12 hits back to back without getting anything close to a dry hit. That's 12 hits in 12 breaths. and I did that three times just to make sure the results were consistent. I think that speaks highly of the rayon's wicking ability.

i only vape sub-ohm and have only had stellar performance with cc.
.22 up to .37 in drippers....
.47ohm in a fogger v4.3,
.55 dual coils in a kayfun, the other kayfun is .6ohms but only single coil with kayfun drilled out
.67 dual coils in a taifun gt
once i played around with it and learned the right amount to wick with, only stellar results.....no problems at all
all the problems ive seen are due to wicking error.
going sub-ohm is no problem at all. in fact i would say rayon is begging for you to nail it with all the power you can.
if your used to 9 watts...go to 10-11...
if you use mechs.....drop your ohms.....
ive found that rayon will handle anything you can throw at it..
you just have to play around and figure out the right amount to put in your coil.
the 1.5 rule is a very very good place to start.
i know that when everyone started using cotton there was a learning curve......
there will be a curve here ...but it will be quicker

This is a point I keep trying to get across -

I'm still having trouble finding the right amount. Getting too many random dry hits. I am also experimenting with different wicking methods. Right now, I am using a single coil .7 on a Stillare and spreading the CC tails across the deck so that I have a pad of wick.

Practice?

Yeah but I'm starting to wonder just how long that 500 feet is going to last....

You want to put that in writing? Oh, wait...

Cotton or hemp can not stand up to this, that's why I use rayon and that's why I started this thread.

Similar to cotton but different you have to have the correct density.

Just cause you at 75w doesn't mean your build is hotter. Depends on the gauge, many say low gauge super sine ohm is actually a cooler vape.

25 watts isn't anywhere near 75 watts in heat generation, the difference is when the coil is wet not dry. I have vaped a 32g 1.2 ohm parallel coil @ 6v (stacked 350's in my VAMO) and I have vaped a triple twisted 32g parallel coil @ 0.3 ohms on my mech...nowhere near the same in heat generation, the 0.3 ohm build is much much hotter.

Cotton takes the heat just fine, it just has to be juicier than rayon to do so.

I'm starting to think rayon is not suitable for small diameter coil on my 1.8mm coil it's going great but on my 1.4mm it is giving dry hits in the middle. I will play with the density later.

The coils on the RM2s in my three Reos are all 1.5mm, and it's working very well in those. In the Kayfun and the Fogger I have bigger coils - around 2mm - those seem to work better with rayon in that setup.

well yeah in my Rm2 it's working great but it's a squonker. I'm wondering if rayon cannot keep up with small coils in tank systems.

I mean to pull the wick length off the main coil. Pull off 3" that should be enough to play with.

Yeah man I'm working on how to get the density right. So far it's just experience. Trial and error.

Yes, that's what I think!

Use a bigger mandrel or larger Kanthal wire or both with less or the same number of wraps to get your 1.4 ohm coil.

It wicks faster that cotton. And releases juice to the coil faster. That's why the nic hit, voltage, and juice consumption goes up. If the tails have no juice available it won't wick.

It excels in tank systems, but of course you have to figure it out. A 1.4 will definately be tricky but I'm sure it's possible. It does flash the liquid very fast so it would need plenty of juice available near the coil

Remember back to when you/I said cotton didn't work.. This is a totally different wicking, you'll have play with it.

That's is pretty good "Fisheeboy" but you left out the 30 minute interval between the 12 hit intervals of 30 minutes while you were passed out.

Actually I notice a result on a vertical build I did with CC on an RSST that I have never seen before. I wound a coil slightly smaller than the wick hole in the RSST (~ 2.5 mm). I then mounted the coil on a fully filled RSST then put the wick down thru the coil like twisting in a screwing. I then trimmed the wick about an 1/8 of an inch above the coil. Now here is the interesting part, at least for me, the wick had already drawn up fluid 3/4 the way up the wick that was in the coil and by the time I picked up the top cap to but it on the entire wick was wet... Absolutely no priming necessary.

I have never used any wick material that I did not have to prime be it vertical, horizontal or whatever except for this CC rayon!!!

Ok, so I wasn't sure what I was doing wrong, so i scrapped the build and re-built a 1.5ohm micro. 12 wraps with 28g around a 1/16.

the best way i can describe wicking with cc is to look at your stretch of rayon,
eyeball the width of what you would have with cotton, then add half of that,
i only twist what you will use as a leader into the coil...
i may gently tap the length of wick but not compress it much.
if your having problems with the leader being to thick...youve got too much.
when installing it....best way i know how to describe it is lightly snuggly....
if that makes any freaking sense....
your coil might have a little movement...if it pulls your coil...toooo much

hope this helps someone......
if you have problems....add a little more then compare......or a little less....
rinse and repeat

heres how i did my dual coil build on one of the kf's

 

[brianc11111]

vassilbg........

ive always had good results draping the tails onto the wall and just touching the deck...
never covering juice channel.
id be willing to say you might be a little lite on the cc

Hopefully its just right but I'll keep an eye on it for a tank and see how it does. Otherwise I'll re-wick it later tonight. So far its been about an hour and a half and its trucking great... time will tell

so far so good........awesome!!

 

[stashbldr]

it is lightly snuggly....

"lightly snuggly" .. ha ha ha .. great way to describe it. I've tried describing the feeling it should have going thru the coil to several people but couldn't quite explain it ... your "lightly snuggly" describes it perfectly ;-)
