Coppervape's Skyline Clone

[benley73]

On some of them it seems like the outer o-ring on the LFC cap is wrong. There is one that is a little bit smaller diameter in the spares bag. Swap it out for that one and it will be much better.

Had to do it on the one I got from FT, but not on the one from CV.

Same here my branded one was fine my unbranded needed it swapping out , works fine now

Yeah. I can actually feel the suckage. The JFC gets harder to turn, and when the bubbles rise it becomes easy to turn again. It feels like opening a refrigerator door that is stuck because of vacuum.



That sounds pretty much similar to what I do. TBH I think that wicking this way or that way might relieve the symptoms a bit, but it won't solve what is clearly a design issue with this tank. I also noticed that pbusardo, in his review of the authentic, recommended to open the JFC a little bit at a time.

I am gonna try to remove the o-ring on the shaft of the inner chamber/JFC tonight, and see what that leads to. Maybe that is the cause of the vacuum?

I believe it is part of the problem , replacing with the smaller one makes it a lot easier to use ,
but has the down side of causing a slight wobble of JFC on top once swapped over but fixes the tight jfc + vacum seal. as paul B reported on original so i think this was there fix too to make it smaller ,

Hmmm, looks EXACTLY the same, even the accessories, I BET that both companies (Coppervape and SXK, if SXK really is a company) buy from the same OEM manfacturer and "relabel", it´s probably build in the same factory... and I still think besides tasting great this tank has a major pressure problem. Almost impossible to refill and reopen JFC without major leaking, even when hold upside down...

I thought this before since most of my Coppervapes stuff was unbranded where as SXK where fake branded, since i knew it was clone never bothered about having branding , maybe be just sub companies , seems this is what all big china compaines are doing

can someone tell me how many mls can fit up to the top o-ring of the tank? thanks

 

[akistr]

and also, has anyone put the o-rings from the original to the coppervape clone? do they match?

Ok, so it seems I have confirmed what I was suspecting: It dumps juice into the chamber when opening the JFC. Here's how I arrived at that conclusion:

1) Had a vape break, everything worked normal.
2) Took out the base to check and it was adequately saturated.
3) Put the base back in.
4) Closed JFC.
5) Took out the base again to check, same result as 2).
6) Put the base back in.
7) Opened the JFC.
8) Took out the base again to check. This time it was totally flooded.

I know one "solution" is to open the JFC carefully, but to be honest this is a bit of a pain in the ...., since I'll have to vape it and try to sense wether the wick is dry or not as I open the JFC a little bit at a time. This is far from user friendly.

First I thought this was a consequence of pressure in the tank after filling from the top, but when you screw the base in there should be no such thing. It indeed seems like there is a vacuum issue with the JFC as I think someone earlier in this thread mentioned.

If someone has a better workaround or solution I'm all ears!

Ok, so I removed the little o-ring on the shaft of the inner chamber, and did the following experiment:

1) Filled the tank with disposable liquid.
2) Removed/inserted base to relieve pressure.
3) With the tank upright, opened/closed JFC 3-4 times in a row.

That led to juice pouring out of the airholes.

I did the same thing again, only now with the tank upside down when opening the JFC. Then I did not experience any flooding. I even removed the base to check, and saturation was fine.

So my conclusion, and disappointment, is that it seems like the tank must always be upside down when opening JFC, or you'll have to open it a little bit at a time while vaping and hope that you can sense the dryness of the cotton adequately as you open the JFC.

If someone can repeat the experiment and post the results, that would be most helpful!

The only workaround I know if is to set it to 420•F or less and have the jfc so the wick is slightly starved, that way you can't burn the wick and it won't flood. This is how my gf uses it and it seems to cut down on a lot of the issues I was having when I was using it.

Ok, so I have thought a little bit more about the issue I am having with this tank (flooding when opening JFC), and come up with a theory:

As you open the JFC, air is being compressed in this area:

The air is then forced into the juice reservoir, displacing juice into the chamber.

Proposal for solution: What about drilling a tiny hole here?:

That would make the air escape into the chamber and out the airholes instead of into the tank (route of least resistance).

I am not sure if I am willing to risk this on a whopping $20 tank. What do you guys think? Would it affect airflow in a negative way, or have other unwanted consequences? Do you think it would solve the issue?

I'm pretty sure there is juice surrounding that so I would think drilling a hole would just flood the chamber.

The only Oring that needs replacing if your JFC is tight is this one in picture

The blk oring just under top part below drip tip , is only one that needs replacing,

it has 2 spares same size in spares bag, but choose the one smaller than this,
change to the smallest one in set stretch it to fit its a bit smaller than the one your replacing ,
But makes a massive difference in how tight the Jfc twisting control is ,
I've not changed any other Orings. No need to , this oring under top cap as pictured above determines how tight your JFC twist is , the smaller it is the easier it is to turn. The bigger the tighter to the point you need tools to turn.

Reducing to a smaller size also helped the suction pressure when first reopening the JFC in the tank , when you hear a slight squelch sound,

Airbubbles means its soaking up juices as it should an wicking fine.
Having No Airbubbles would be a problem and lead to dry hits.

The Wicking you dont want long wick tails you want to only place them over the decks juice holes cut the wicks at a slight angle underneath them.

This keeps it away from central airflow you can see the slight angle on my wick tail underneath not much but enough to help.

Then Use a pin or similar thin tool to push the wicks down into the small space between the deck juice hole slots in outer edge of inner deck,

make sure no wick is hanging back into the air intake disk area if ther is a tiny bit juice will use capillary action and weep into the airflow causing leaks (same on any atomiser)

Mine does not leak when wicked this way,
I have had it leak in past,
but was down to my own wicking style
An using too thin of a wick tail put behind decks juice intake hole,
Keep wicks away from decks Airflow under the coil too.

This has been my biggest problem on most RTA,s that had any kind of problem, Seeping juice down airflow into base,

Once i was aware of keeping wicks away from it ,
it stopped all seepage into the bases on all Atomisers [emoji106]

I dont think its a Design flaw,
Mine works very well now that Top cap Jfc oring had been swapped over,

I do honestly think its down to Personal / individual wicking styles,

Dont over fill if you do once you screw top cap on.

You do nothing more but force juice through the bottom of the tank creating more pressure,

Fill up to just under the two juice holes, so has a small Airgap

Sometimes you get it right on first go,
Other times it needs a little more attention,
every new Atomiser needs a slight difference in wicking.

Then enjoy a leak free , easy to turn JFC controlled Skyline , [emoji39]

Nice post benley, and thank you. I'll be getting my SkyLine Thursday (if USPS tracking is correct) and already have my extra air disks from FT, so I'll refer back to this post in setting up that spare o-ring for the JFC and wicking. Thanks again Benley.

 

[guvnaa]

Nice tip benley73. I replaced that o-ring with the slightly smaller one and the JFC turns much easier now. Before it was a pain and now it's nice and smooth!

 

[mrjohs]

@benley73 Thanks for your effort and thorough explanation.

However, I do not think that it solves the problem that I am having. I had the hard to turn JFC on one of mine and that was easily solved by changing the o-ring as you suggest.

The issue I am having is that the tank dumps juice into the chamber when opening the JFC. This, I believe, is caused by air getting compressed as you move the chimney cap upwards towards the bell. As I turn the JFC (with smaller o-ring) I occasionally feel it getting harder to turn, until it "burps" air down into the tank. You can see the tons of bubbles appearing as this happens, and feel the JFC getting much looser.

Try one experiment to verify/disprove my theory:

1) Close the JFC with tank upside down.
2) Open (all the way) the JFC with tank upright.
3) Repeat 4-5 times.

I bet you'll have a flooded chamber, no matter how you've wicked it.

I have now removed the o-ring on the shaft of the inner chimney. That should let the air travel upwards as I open the JFC instead of into the tank. We'll see how it works out.

That might interfere with the vacuum, but I doubt it has too much vacuum to begin with.

Just rebuilt my second Skyline,
This time using the disk with large Slot hole within ,
I

Where the tool is to the back of the deck is only where i wick it up to i leave it wick free along front of deck , so its mainly over tje decks juice holes as i have mentioned previously,

Coil..
Coil Demon killer coil SS (0.5) reading at 0.56 wicked again with rayon

5 wraps +2 outer , flat clapton demon killer Flame coil 316L have 6 of these well 5 now [emoji39],says it a 2.4mm x0.4 x.04 but did put an extra wrap on an pulled down to 3.5mm ID on my coiler tool,

Wicking Rayon

I keep the wick over the decks Juice channels

Been under the coil with a dentist tool to make sure no wick is over the insert in Airflow intake

Finally firing juiced up wick
This one rocks

Being full 316L TC /VW so dual use juiced up with Fruity loops cereal mix Blended with Lemon Tart So nice sweet an sour tasty vape,

Again No Leaks ,

Thanks for the top cap Oring tip, it solved my very tight Fasttech non-logo LC problem.
The two Logo'd ones I got from 2fdeals didn't have the problem.
I think the Fasttech non-logo version is probably made specially for FT cheaper and had less quality control.
Also the peek Airdisk set I got from Fasttech are slightly lighter colored than from 2Fdeal, I don't know if that means anything

 

[benley73]

You still get juices seeping back into tank on other Atomisers , my Authentic Taifun GTv3 mini is doing that too
This is just the gunk on the wicks already ,
but have been running my Diy Brithday cake + frosted glazed fried Donuts E juice through it which is packed with Meringue Concentrate for its sweetness rather than sweetner , great with a cup of coffee

Ive had with without logo Coppervapes one with logo was tight needed changing was bought from 3F not direct from CV like my others , im awaiting the SXK version next.
About to place an order for Squape E motion RTA see how that fairs to my R, -R,s and my Dream X Squape RTA,s which I use regularly.
