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

[JeremyR]

Oh yeah I have since ditched "micro coils".. once I tried a spaced coil I noticed nothing less and only better. The center doesn't gunk from holding juice on it. I think it works better lasts longer!

Tight coils have little benefit to me anymore. - I just don't feel its safe.. Lol

Some of you will get that.. I have a better peace of mind not doing microcoils, I just don't trust em.

Here's my first build on the infinite clt dripper. This is my first true dual coil I've done.

32g, 5/64 ID, net 1.4 ohms - 2/ 2.8 ohm coils = 1.4 ohm.. Vaping it at 6v, 20+ watts and it vapes great!!!

Coils and placement




Started with one medium delasco rayon ball full width pulled in half length. One half for each wick. Here it is after the first trim.



Trimmed again and then more after this pic.



The tails just go down and under, very similar to how I do the flashi just a little different. Air slots lined up and even with coil, air at 50%

Vaped my first juice down till the wick was dry, just perfect. It actually vaped for quite a while on the first load.




Close up, you can really see how the rayon drys out, I wasn't even getting a dry hit off this yet!! (It was all completely saturated this was not a set-up. ) you will never see cotton do this in your life.



Verdict - vapes great, less filling.

Oh yeah just one piece each and no it doesn't collapse in the middle at all. Pull till it stops then grab close to the coil and pull on each side hit so it's tight but doesn't pull apart to thin. If you grab it further out the rayon will strech and get thinner. You do this if it's too thick. you get the tight part through to the other side check for rayon song and your good. No too tight but snug.

This is straight 32 spaced. Coils didn't even deform during this. So if someone says it can't be done... Skip over it.

What did that ohm out at JR?

 

[atroph]

Thanks Jeremy. I have put almost 15mL in my current build and I was totally surprised to see near ZERO coil funk and wick blemishing. I am thinking that the center of a tightly spaced coil gets too hot on the opposite side of the air hole to effectively cool the coil leading to harsh-ish hits (IMO) with my juice du-jour. When dry firing a spaced coil I can blow on it and completely cool the coil whereas on a tight coil the opposite of my lung wind side still glows slightly. The tight coils do produce some huge vapor at lower watts but at a cost of a potential harsh hit. I'd rather bump up the watts on a loose coil and avoid the harshness altogether.

New build:
Dual 30ga 11 wraps 1.59mm 2.4 ohms each net build 1.2 ohms. Currently at 18W and it vapes super smooth. Have bumped it to 25W and it held just fine, but was just too excessive for me. 9W is about what I use in single coil mode in my Patriot which it also vaping so much better with a loose coil.

New patriot build:
9 wraps 30 ga. kanthal 1.59mm ID. 1.7 ohms net build. Rayon wicks (duh!).

Those are some nice looking spaced coils, atroph!

Good job!

It is super easy to do. Wrap coils around mandrel like you are going for a tight coil. Pull the legs apart so that the coil is SUPER spaced apart. Then smush the coil back to the stop on the mandrel. The coils will spring back in a nice even spacing every time. No torching necessary either with a small mandrel that I am using. Just dry burn on the RDA before wicking and it holds it shape.

Not as easy to wick as compared to a tight coil, but not that difficult either. I bet that 32ga that Jeremy is using is a little tougher than 30ga that I am using. If the coil starts to pull I use a toothpick to hold the leg in place so it doesn't deform.

1.4 on the zmax bro.

1.3 is it's limit.

I forgot your the stacker!

Jeremy, Is the fibers on those delasco ball's courser then the Sally's and the Melatonin or is the close up pics just making it look that way?

 

[JeremyR]

Yeah stacked 18350 imr in the zmax v3 telescopic. Battery voltage 8.4, pumps out up to 24 watts. 6v to a 1.4 ohm coil no problem. and that wattage and voltage was tested to be true.

Close up pic.

It is the next fiber weight up from Sally's. Also I think the bottle rayon is even courser/heavier than the delascos.

Hold up wait wait wait..
Are you telling me there are different kinds of rayon! Oh my my my...
:sigh: lol

Build looks great Jayman. Wicking after vaping looks even better! Rayon! The wonder wick!

 

[JeremyR]

First build on the Aether Tech pv clone, thanks jax for sending me this to play with, much appreciated! Much the same as I did the clt. So a little redundant.

It wicks good, just contending with the negative post air hole; if I drip on the center or on the outside more than the wick can hold. I see why jax runs a full wick on this; there is no juice well with the 2 air holes at the base of the "well".

I feel it could definitely handle a lot of wattage. But with no well there would be a lot dripping after at high watts.



More trimming on the outside wick was done after pic.





The inside wick was thinned at the bend ~50%.

Jeremy, You can loosen the 510 screw at the bottom of the atty to loosen the "T" post. Once the "T" is loose you can turn it any way you want. Reinstall the 510 screw and tighten to lock it into place.

I have blocked off the bottom holes (insert toothpick and snap flush) as they tend to get juicy or I have issues getting the holes lined up perfectly as well as getting the middle airflow aligned with the coils. It is a good vape for sure, but a little "leaky" for my tastes. The juice doesn't flow out, but I have found that it you touch the barrel it seems to get everywhere. YMMV. I definitely don't trust it in my pocket.

Also if you find that the screws are cutting your coils you can polish the bottom of the screw with a little sandpaper. I used 200 grit for a rough cut and finished with 800. It only takes a few passes to get the imperfections out of the screws.

I'm sure you know, but I just dealt with a big TOBH yesterday where the positive pin had been overtightened and had to be trimmed so it would fire (couldn't get it off the pin).

Make sure you don't over-tighten!

I put the T post at an angle on purpose to direct the negative air flow to the coil. See how air comes in it hits the t and will be directed to the coil. Instead of just going straight into the t and splitting both ways. Don't know if it makes a difference just thought if try it.. With air flow dynamics in mind I thought it would flow more toward the coil... Jury's still out, lower air hole will probably be filled soon so I can get some capacity in the well.

Sounds good! It looks like the AcerRig clone has better screws than my Tobeco. I have found that juice somehow gets between the top piece and the barrel and still gets the bottom holes juicy. I have flipped the barrel before to put the 3 holes at the top, but my OCD cant stand the logo being upside down.

Rayon wick, possible side effects and causes.

http://www.flavourart.co.uk/blog/rayon-wick-possible-side-effects-and-causes.html

Rayon has a number of properties that make it a good candidate for coil wicks: the structure is uniform and tubular which allows easy
passage of liquid along it as the adhesion to the filament walls is stronger than the cohesive forces between the liquid molecules.
Rayon has a high absorbency level coupled with an efficient release level; it suspends liquid very well but does not cling to it excessively.
