Changing Coil Vs. Changing Cotton

ok ... so there was a thread that showed insect droppings in some cotton someone got with a RBA ... but I can't seem to find it.

So I thought I'd have a look at the cotton sample in my Kanger Subtank Mini & .. sure enough ... bug bits & little black "dots" (bug poop I assume). Okay ... fine ... I've not used it & will not use it. I have enough cotton (bacon) to keep me going for years, and I'm happily puffing away on the .50ohm OCC premade coil supplied by ........

........and then it dawned on me that it was supplied by the same folks that put a wad of bug-gunk-ridden cotton in the box with my ST mini ... Kanger.

So ... the question is if anyone has taken apart the OCC coils & found little black specks in the cotton, or other foreign "pieces" ?? I'm wondering if the cotton Kanger uses for the OCC coils is the same cotton they give you in the box to wick the RBA deck with.  

Ok the title was weird to draw attention

Have u guys ever open your rta and see the cotton changed it's shape??? Its not it was caught on the bell threads while I tighten it cause the way it was disformed (if there is such a word) don't show it was that the case....just was fluffier and a part of it was pulled close to the air holes under the coil....I noticed something was off when I was puffing and opened and saw that....I just fixed the shape of cotton with a screwdriver and keep vaping it but was curious if anyone have seen their cotton change shape....like a cotton candy  

To keep this short I tend to change flavors in my delta 2 quite often and have a large assortment of flavors. That being said I never have enough replacement coils to keep switching them out fresh for flavor changing. I do wash my tank every time I change flavors but I don't wash the base and coil over fear of messing something up since I don't tend to let them dry before I decide to start vaping it again. I usually don't think about the transition flavor however I made the mistake today of switching from a caramel macchiato to a vanilla banana wafer pudding so as you can probably imagine the flavor is complete trash.. With all that cotton in the delta 2 coil, how long should I expect to have to vape like this? Ten toots in and I can still taste the macchiato like the cotton is reserving it just to teach me a lesson.  

I have been using an evod for two years now. Yeah, I know, minor leagues, but it gets the job done just fine for me.

For the first 18 months I was constantly buying new coils. I work from home so I can basically vape all I want and I vape A LOT. I use Swagger as my ADV and it will destroy a coil in just a couple days. It was becoming difficult to even find coils to buy and it was getting expensive, so I did some research on rebuilding my own coils. At first I tried to build them with silica wick, but I could never get them to work right. Using 1mm silica wick wrapping around a stick pin the wraps would always be too big and there was lots of leak/gurgling. So I went the cotton route and would wrap around a 1/32 drill bit and then slide the cotton through the coil. Works great, perfect ohms, great flavor. I've been doing this for the past six months. In the first 18 months of vaping I never got sick once. Since I've been using the cotton wicks I've been SEVERELY sick twice (probably a respiratory infection but never went to the Doc), and now I feel like I'm getting sick AGAIN.

I've noticed that I can see little flecks of what looks like cotton building up on the mouthpiece, and I'm assuming, going into my lungs. I think this is what is making me sick--the buildup over time. Anyone else had issues with this? I think I may have reached the end of my rope with vaping and now maybe I'll do what my original intention was (quitting altogether after vaping for a short period of time).

Anyone have any tips on rebuilding coils with silica? I've watched a million Youtube videos and replicate the process perfectly, but the wraps end up being twice the size they should be and I've been unable to slide silica wicks into the coil like I do with cotton because even at 1mm it's too big to fit through the hole. Thanks for any help.  

I just re wicked my coils and now the flavor seems muted. I used more cotton this time but not sure if it's that or the cotton itself. I usually dry burn and re wick about 2 to 3 times before replacing the coils and this would be the first time I've re wicked these coils. I use Japanese cotton I ordered from fasttech. Has anyone had issues with their cotton? Any suggestions would be appreciated. Thanks.  

I just got some japanese cotton pads and I have been building my rba section in subtank for a little while with organic cotton balls and have noticed that after I take a puff off of it I get this sizzling after I let go of the button I've read it could be to much cotton but I tried a very little amount of cotton and still get sizzling.. I'm using twisted 30 awg. Reading at .4 any idea?  

So I decided to try a 1,6 ohm coil on kayfun v4 clone Tobecco and I am using 28gauge Kanthal with a cotton
wick on a Rdna 30 and its vaping well at 15 watts I have a kanger subtank mini coming in the mail and here goes my question
So the kanger subtank states that with a .5 ohm coil i could vape up to 30 watts but the voltage comes in at like 3.8 volts
I was under the impression that the rdna 30 needs at least 4 volts to work which kinda brings me to my second question
What is the point of of sub ohms? cant i just build a 2.0 ohm coil or something like that to achieve the results as if i was subohming
I am very confused on this
thanks for the replys in advance
Oh yea is a 1.6 ohm coil at 15 watts a normal build or any recommendations for the kayfun v4 for watts and ohms thanks again  

It's about that time that I have started to re-wick the OCC coils in the subtank. Looking for some performance tips. I'm currently using Muji japanese cotton which is working well and this is what I have noticed...

too little cotton, the atom will leak and burn easily
too much cotton; no issues burning at all but the flavor is muted.

I've re-wicked 5-6 times this week to experiment. With the Muji sheets, I cut about 5-6mm strip, remove 1/2 the thickness, then after threading through the coil, I will cut about 4mm from the end and stuff it back in the OCC head.

What are your tips and preferred materials?  

Is this normal?

This tank is new for me and the coil has cotton coming out of the holes. Def did not notice this when I first put it together and filled. Is this supposed to be happening? My old aspire coils never looked like that.

I can only get about a 1-2 day life span out of coils that are organic cotton based. After 1-2 days, they start seeping a dark colored liquid into my tank and ruining the juice. This has happened in my Atlantis tank running Melo coils vaping at 32 watts and my Herakles tank running 55 watts. Keep in mind I vape about 7-10ml a day. Juices are 70VG/30PG or 80VG/20PG all at 3mg nic.

On the flip side, if I vape old school Atlantis coils at 32 watts on the same juices, I get a full week before this happens.

Any ideas on how to make cotton coils last longer?! For this reason, I can't wait to get my Lemo 2 in. I'll be able to rewick daily and not worry about cost.

The way things are going, I am losing so much money on coils it's nuts. See picture to see whats happening.

Oh yeah, this is happening on all kinds of juices I vape. Mt Baker Vapor, Vista Vapors, 4 Pillars, The Milk Man. Some are budget juices - others are premium. No matter what juice I use, it happens.

The BIGGEST killer is Zeus Juice with 80%PG, 20%VG. This juice kills a coil in one tank full. I'm guessing the sweeteners in that juice do it.

It's frustrating because I LOVE my Herakles tank running at 55W but if I have to replace the coil every 1-2 days, that's SO expensive.
