New cotton wick...burnt taste everytime

[briandress]

Hey guys,

my setup is a 14500 bagua clone...using a .8-.9 ohm single coil rda from my local B&M.

every time i put new cotton in the coil i get an intense burnt taste for the first hour or so. anyone have any idea what this is?

i am using 100% cotton balls from cvs

I don't have any experience with that RDA, but my guess is that you have too much cotton in your wick which is causing it not to wick efficiently (choking at the coil). In my KFL, this was my main problem when learning to build it.

Also, with a new wick, I have to vape about 1/4 of a tank before any residual cotton taste is completely gone, but after that is is rocking and rolling. Again, this is with a KFL, so your mileage my vary.

IK can help ya. It looks like you have a little too much cotton in there. It takes time to get cotton density down packed, but with practice you will find it. Also I recommend making your coil vertical on this RBA. It seems to wick better on these style atomizers.

i see. does it look to be too much from the photos? i think with so little ammount of wick i would be constantly dripping! any reccomendations on a good small sized tank?

 

[Spacedoutart]

Not really. I do recommend continuing dripping and learning great coils. Then stepping to a tank if you wish. Most tank rebuildables can be tricky and finicky at times.

As for cotton density make a strain of cotton as you did before, but varying in thickness. after inserting it into the coil, slide it down until you see the cotton bunching up. That bunched up part it just too much. so back it off a little and clip to size.

I recommend the vertical coil in your style rebuild able since it will be able to access the juice well easier.

im not sure what you mean about vertical coil...all i ever do is put the liquid on the cotton when i drip. there is no extra in the bottom really. will less cotton stop the initial burning taste? i need to find a place to order the right coil as well. and probably an ohmeter


how would i even make a vertical coil? the coil goes straight down into the post with screws on the side to tighten

also, the cotton that is inside of my coil is definitely black at this point...does a good coil/cotton density prevent this from happening so quickly?

 

[Spacedoutart]

Yes. Proper cotton density does correct this. When there is too much wick. it swells once wet and gets choked. preventing flow of juice to the wick inside the coil. Which is why it burns. Yet when too little parts of the coil will not be touching the wick and burn hot right away (hotspot).

Im not truly familiar with your dripper. What kind is it?

Once a cotton wick is burnt, it's....well....burnt. It will never taste good. When you accidentally burn a cotton wick, it needs to be changed. If the cotton inside your coil is black, you've burned it. Cotton takes a while to fully saturate with juice. Whenever you insert a new piece of cotton, put a few drops of juice on it, and let it sit for a few minutes, so that it becomes fully saturated. Never try to dry burn it.

i just put some new wick in...a lot less cotton. got the burned taste for sure. im just vaping puffs and rewetting until it goes away.

 

[Spacedoutart]

Nice.. a lot better. I see it would be perfect for a vertical coil. Like this on a optimus.

14500 and subohm? I may be wrong, but I think your ohms are too low for that setup. Is it vv? If it's burning, your voltage (or wattage) is too high. You said in another thread the people at the shop build these for you. You should go in and talk to them about it - if they built if for you they should be able to tell you what's wrong! Once cotton is burned it's no good - you have to rewick it.

 

[Spacedoutart]

About the vertical coil...
You can keep the top coil leg in the hole the legs are in already. For the bottom leg, I would put it in from the back of the tightening screw hole and up the center pole. And clip the cotton so its just touching the deck. That way it can hold a couple drops more juice keeping the wick wet.

 

[briandress]

i really like the vertical idea. where do you get your coil? any recommendation as far as what gauge i should get? do i absolutely need to get a torch like the B&M guys who flame the coil up before they put it on? the hang up for me in my brain is that you can see on mine that the posts take the coil at the top. how do i make the coil vertical and have the ends go into the top of the posts?

oh ans thanks so much for your help spacedoutart. very helpful!!

it is not vv. just a little mech mod. they built it at .9 ohms. i mean they are helpful but seem no where as informed as you guys are here. I would rather learn the right way as opposed to the "ooo look you get huge clouds" way...if that makes any sense.

I just super saturated the new wick and let it sit like you said. Way better. Already I am feeling better about my setup...no need for a new atomizer I think.

Another thing to confirm would be your airflow. Make sure that it is across your coil or it will get too hot and burn. The vertical coil recommendation may help on this as well.

Keep posting your results please! It doesn't look like your cotton is burnt in your second set of pictures so if it is still tasting that way it might be the cotton taste working off. You could try boiling your cotton in a pot on the stove. Most recommendations I have seen is for 1-2 20 minute sessions with cool water rinses in between. I just suffer through the first 1/4 tank myself which doesn't take all that long.

 

[Spacedoutart]

No I dont go anywhere, I make my own coils. I personally recommend 30 gauge. Not too much, not to little.
No you dont need a torch. It just makes the coils less springy.
Find something a small diameter that you like. like the inside of a pen that holds the ink, or a something else similar. Also around the same diameter as the coil is now. Then make 5/6 wraps around it making it look like they are touching (about 1.3 ohms). Keep one of the legs long on it. That long leg can be inserted into the hole on the back of the post (opposite of the screw head) and out the top. Then tighten the screw down. Then insert the other end of the coil into the top post where the wire is already coming out of (as shown in the pictures you have posted)

after wicking with new cotton, are you wetting the wick before taking any vapes?
The reason I ask is I have never had any cotton wick burn at .5 or above and I have made hundreds of them using cotton.
If you have pre wet the wick and get it nice and soaked and is still burning you need to up your ohm on that coil build to more around 1.0 to 1.3 ohms and try that.
PS> are you sure it is cotton burning? Is your air hole lined up right by the coil? have you tried different airhole positions?

SORRY. meant for this post to go to OP NOT Yot

 

[Spacedoutart]

And BTW I use the same CVS cotton as you. And I dont not boil them. They have a very clean taste. But with more practice and time, cotton will be a breeze.

Time to start learning to wrap your own coils! I hope your local B&M didn't charge you for your setup, seriously, it is a 5 minute job once you get some practice.

Since you are wicking after your coil is in, you don't HAVE to have a torch, but they are pretty cheap and useful so I recommend one. If you don't have one, you can dry-burn your coil once it is installed to burn off any impurities before you add your wick which you will also do anyway to make sure you are heating from the inside out and to check for hotspots. I personally torch wire before wrapping as it makes the wire easier to work with IMO. Additionally, you can do most of your coil "pinching" with the torch as opposed to having to having to do it all once installed.

Wire material, gauge and coil diameter are all variables you will have to play with based on what you are vaping and how. I personally use 28g Kanthal A1 and wrap 1.2mm inner diameter coils around 1ohm. Again, this is part of the joy of rebuildables as you work towards finding your personal best setup.
