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

[JeremyR]

Question about wick "break in". After a new Rayon wick, often times the vapor is very thin, maybe a little harsh. It seems the rayon isn't touching the coil enough or something. Its like vaping water almost. After a few minutes of use, vapor gets thicker and flavor comes on stronger. Is the wick loosening up and making more contact as you vape it? Maybe residual water from the chimney threads diluted the juice in the wick? I'm curious.

2 things it could be.

The coil is too saturated and juice needs to burn off because the wattage is on the low side. An oversaturated wick with have low vapor and a harshness to it. No matter what wick you use.

If there is any off taste, rayon has a slightly nutty type taste, you wick may be too tight. A wick thats too tight can break into to a usable wick as it purges air and reduces in size. The amount of reduction is about opposite the amount that cotton expands.

Well if there is water on top of the mix it will fast track to the coil also.

Most likely it is the first scenario. Too wet too little power for the amount of juice. Try to just prefire the coil a few times after you know its fully saturated. Rayon holds a ton of juice and takes a minute to fully saturate

Just ordered some off of Ebay (had some leftover paypal Xmas cash) and looking forward to trying it out... Got a bit of catch up reading to do

Nice to hear. I have a reel of 28 gauge tempered ni 200 on my way myself

Didn't knew if I should pick the tempered one but heck, I had to try it.

Keep us posted about that tempered Ni200 because I only used annealed Ni200 wire so far.

But on the second thought: Once I dry burn tempered nickel until it glows - it will become annealed anyway. Will it not?

AMD,

You are probably right on the tempered becoming annealed after you dry burn but I would also like to know what tchavei thinks of the tempered. I personally don't dry burn the nickel not out of any Nickel concerns I have just gotten so lazy about the Nickel coil building that any step I can leave out the better. I found myself spending more time trying to get the Ni200 coils just right than actually using them - Ugh!

AMD,... I thought so... but wanted to confirm it... and while I have only found a single source at the moment... it looks like you/we need to better understand the temperature that it's reaching.

Material	Open annealing *C	Closed annealing *C	Stress relieving *C
Nickel 200	815 to 925	705 to 760	480 to 705
Nickel 201	760 to 870	705 to 760	480 to 705

Any chance you can set your temp limit to around 1300 *F (705*C) and give it a shot?

EDIT: Cleaned up the table

Nice to see you here I think you'll like Rayon. I'm getting lot of mileage from my coils with Rayon. I haven't used them with NETs though.

How are you guys getting so much mileage from your coils? I have to rewick and dry burn my kayfun every day or it tastes like crap. The coil still gets hard, black stuff that accumulates and it destroys flavor big time. The wick rinses off pure white, but that doesn't help the coil at all.

I'm not the expert here but I do have one liquid that gunks up the coils pretty fast. If I avoid that one, with mostly Hangsen tobaccos, I can almost go a week with about vaping 4-5 mL a day. What are you vaping? Maybe others with kayfun experience can chime in...

 

[awsum140]

I think it's a combination of things that give "high mileage". Finding the right coil, resistance/diameter/wire gauge is the first key. Next is getting the right amount of rayon in the coil. The last trick is trimming the tails just right to allow the best wicking action. Problem is they all vary from atomizer to atomizer and if one thing changes, everything else can go to heck in a handbasket. As a side note, a spaced coil seems to last longer than a tight, or micro, coil.

For example I was running a Fogger at 27 watts with no problems. I dry burned and re-wicked and can't go over 22 watts or it gets to harsh. My experience so far has been the larger the diameter the coil, the better the results. Of course, a lot depends on the liquid in use as well. NETs seem to foul coils very quickly even with rayon, check with Dusty on that.

Welcome! Your vaping life is about yo get some much better with less work.

Thread search is your friend!

Search - how to , videos, trouble shooting , troubleshooting , repost , ect.

After a day would indicate your loosing contact from being too loose.

Or - Too much rayon either in the coil, usually acompanied by the nutty taste of rayon for a while..

Most likely the issue is poor wicking because it's being treated like cotton. Fat tails take away from the wicking ability.

One way or the other or another your losing wicking ability.could even be related to the device not feeding the way you have it wicked.

Pictures can speak a thousand words if its clear.

Thread search - roots , living, or heart.

Awesome was on point though - to get 100ml is a set of differeent variables.

The thing I left outis that it doesn't take all that much experimentation and once the right combination is found, all the effort is well worth it.

Indeed it didnt take long for me to find my wicking needs, now i can go for weeks with out changing. Even though most times im rebuilding every week, trying different coils spaced/contact/ect, ect.
Also the atty becomes a factor in how you need to treat the rayon. I've got the right setup figured out for my igoWs, and my TOBH(well i did, i drilled 3 new holes so it needs tweaked.) got my big dripper figured out. But Still working on my kfl(latest setup is looking good).

AIRFLOW is also a high factor in gunk build up. If your running a kayfun light at high wattages without opening up the airhole you will get gunky significantly sooner
IMO

 

[JeremyR]

Yep if you go about methodically it won't take long.

Another important factor in wicking speed of your juice is temperature. I'm Fighting my 100 VG today in this cold. Keep having to dry pull to keep it wicking from the tank.

I have no idea. I was told the annealed was better for silica wick builds and the tempered one was better for cotton builds. Dont know why but I guess I'll know in a week or so.

Just wish my FT mini clone hadn't disappear in transit or I could slap a dna 40 in it right away

I'll rewick later tonight and post pics.

Update on my Protank II head rebuilds, I took the advice and wicked with much less leaving a small gap at the slots and trimmed the wicks shorter then the flange leaving space between the recess in the base and the side of the heads and so far so good. It goes against my nature to leave a gap at the slots, just seems like that gap would cause flooding into the heads but I'm on my third tank and not a sign of any flooding, I guess it's just hard for an ole dog to change habits.

Thanks guys, I'll let you know how the longevity goes. If this Protank grows on me I may have order a few more and finally make a move from my T3S clearo's.

 

[awsum140]

I was worried about leaks and gurgling, too, the first time I did one, Willy, but no problems at all. Surface tension and the slight vacuum in the tank are your friends in this case and I think the little gap allows air in at just the right rate to improve the feed/wicking.
