Wick thickness and vapor production (question)

[subver]

Hey guys.
So at first I was using 3mm silica wick which worked well enough, but I was getting some fraying because of how thick it was (it would get caught in the threads)
So I moved onto 2.5mm. I would put 3 strands of silica wick under the coils with the 2.5mm wick, but for some reason I would have to hold the button longer to get vapor.
Now I just used 2.5mm wick, no strands, and it produces vapor very quick, but I don't think I can take as long of a drag because the wick doesn't hold as much juice. (edit: actually the more I vape on this wick the longer I can take a drag.. so maybe it just needed some warm-up time)

I see a lot of people making coils with extra wick underneath the coils - and theirs produce vapor very quickly..
Am I doing something wrong? I use about 1.5 inches of 32 gauge kanthal wire each time.
Maybe I used a little extra NR wire when I made those wicks, but I think they were about 1.9ohms. This one I just made is 1.7ohm

Is there really a huge difference between .2ohm?
The wicks with the strands under them also seemed to gunk up way quicker than the 3mm wicks did - is there a reason for this as well?

I'm still trying to find my perfect setup

From my experience the thicker the wick the higher the watt. I vape on 2.5 dual coil on 7.4v with 5 strand of 2mm on top and 2 strand down the channel. If i use anything less it will burn. But with this set up i never get any burns and god the throat hit is unrivaled while maintain decent flavor. If you are on 1.7ohm single coil and 3.7 volt you will not need such a thick wick. I think 1.7ohm is a bit high for 3.7v. You might want to try 1.2ohm with a low gauge wire so you can still maintain good surface area. If it burns then add another strand of wick up around the coil.

My friend the answers you seek will take some time. some homework will be needed to be done. there is a balance with ohms, volts and amount wick in order to achieve a good vape.

Dare I say "That's what she said"?

Groan.

 

[Poppa D]

The Ody has a big ceramic, it works best at higher watts. Make a 1.3 ohm coil @ 3.7 volts = 12 watts or so, open up the juice a bit and the Ody will rock vapor.

Thanks everyone! I didn't realize wick thickness had a big affect on wattage.. I definitely have a lot to learn still.
Thanks Bishop I definitely need to keep trying different setups.. and I definitely want to try some dual coils but I don't think I'm quite there yet! Maybe when Ithaka comes.

Poppa D, thanks, I will give that a go next time!

I definitely get a burnt taste once in a while with this 2.5mm wick... I definitely like the thicker wick more, so I'll have to try a much lower ohm coil.

i did not get what people are saying that thick wick makes it higher watts. What does the wick have to do with the watts? If you mean when using higher watts you need thicker wicks then yes that's true. However there is another parameter. Thickness of juice plays a big role. When you have thin juice it is very easy, you want more vapor you need higher watts so you need to increase the wick so that the juice reserve stays big. However when you use a thick juice, you are obliged to use thick wicks even with low watts because wicks do not wick well. What i found the best is that thick juices require thick wicks but also a fast delivery of juice. This can be achieved by opening the juice control fully sometimes and keep the strands thin in the channels. And also that's why my iatty does not work well with Boba's Bounty, because the coil is far from the juice (unless you mod it to always have juice close to ceramic). my

Yeah I pretty much just vape Boba's... it usually works out pretty good, but yeah I do have to open the juice control up a bit.. usually 1.5-2 full rotations. My other thick wicks did work very well (the thicker ones).. I think I just had too high of an ohm coil.. so it took longer to heat up. I like instant vapor, as I'm sure everyone does.
I will probably try another setup when I get home.. every once in a while I'm tasting burnt silica with this 2.5mm coil.. I will add more strands and use less NR wire to make the coil.

Subver allow me to break it down for you with this equation.

A coil at 1.5 ohms and a single wick 2mm at 4.2 volts.
Mmm pretty hot and at times can taste metal if chain vaped to quick. Can’t go higher in volts because the wick drying up to fast now.

Now look at same example with 2 pieces of 2mm
A coil at 1.5 ohms and a dual wick of 2mm at 4.2 volts.
Mmm much better it has more moisture in vape. Mmmn might leave it at these volts any higher heat will absorb the juice t fast and get dry harsh taste.

Now look at this example
A coil at 1.5 ohms and a single wick of 3mm at 4.2 volts.
Mmm pretty cool not as warm vape very moist. Need to raise volts to 4.6-4.8 to get a better sensation and feel a nice warmness to vape. Hard to chain vape because wick will dry out pretty fast and need time to saturate.

Final example
A coil at 1.5 ohms and a dual wick of 3mm at 4.2 volts.
Mmm pretty cool not as warm vape very moist. Raised volts to 4.6 and now I can chain vape the heck out of it very very enjoyable.


Ok I kept using same example of ohms (resistance) since ohms and voltage plays a role in it as well as the wick. All three need to be balanced out in order to get a good vape.

 

[Aal_]

Bishop, in your examples are you assuming same ohm and same type of wire? Because if yes it means less wraps which leads to cooler vapor. Number of wraps affects coolness.

 

[Bishopheals]

Aalwani its same wire in example and yes number of wraps will be different because of the size of wick diameter. The more wick you use or up size the less wrap you get if stick to same ohms on a single resistance wire.

Awesome, bishop! thanks, this helps a lot.
When you say dual wick 3mm, is that one piece of 3mm and another piece of 3mm under the coils? I did try this before but I felt that it was too large to fit. I'm better at wrapping coils now, though, so maybe I'll try again
Is this what you typically vape on?

Also.. 1.5ohm is what, about 1.5" of resistance before twisting with non resistance?

 

[Bishopheals]

I use ohm meters for accuracy. You can't be just cutting wires and trying to measure distance. especially when doing any of my complicated super advanced coils. for that best thing is just buy premade wires and use two of them for a dual coil etc.

 

[subver]

Yeah I need to get a good meter. I had a cheapo one from Radio Shack but I returned it.. I've normally been just making coils and measuring the ohm rating on my Provari. Any suggestions for a good meter that isn't too expensive?
Also, if I cut a piece of wire and measure the ohms, will it be the same after I twist it onto my non resistance wire? Or will the tips of the wire be lost where it's twisted?

Thanks, I should probably get that.. perhaps with my tax refund!

make a smaller wire in ohms and use a thinner wire too sub.

wick has nothing to do with watts sub.

Ah ok maybe I misunderstood pimpe. I thought that sounded strange!
Yeah I currently use 32 gauge kanthal, I will try some thinner wire as well! Thanks Imeo.

Hey Bishop, do you have a video by any chance of your dual 3mm wick? I've tried it before and it seemed way too big and was all smooshed and mangled in the ceramic. I will try again, though.

ya its on my youtube channel. look in the ecig playlist for the later ones.
