I'm really liking this idea, not that that the spring is a bad idea at all.
But what exactly are these "greenie" things?


My main concerns with all the materials is what MIGHT leach out into the juice.
--stainless steel pipe screens
--greenie things
--plastic straw
--blue foam
--fluval

I guess I trust the polyfill, but don't want to go back to that.
Tweezing fibers off of my atomizer bridge was a pain.

Kristin's idea is really what we are doing. The cart chamber is the bottle and the polyfill plug is the wicking "stopper."

Now that I've discovered this mod, I have gone nuts and modded my 510s as well.

I also think the springs I used are stainless steel. That's food grade, so I ain't worried.

This mod is definitely the closest thing to a perfect cart solution as of yet. The ideal solution is a very thin membrane that spans the opening at exactly where the atty wick is fully positioned in the cart. That membrane should be able to do two things. 1) support the weight of the liquid and 2) be absorbent enough to soak up juice as needed.

With just filler, whether it be the stock poly, fluval, or wool is that they are too absorbent. While they support the weight of the juice they don't allow it to flow efficiently. The straw mod, may allow for a little extra flow and possible capacity increase due to evacuating air from back of the cart (same process in reverse aids in flow) they are still hampered by the super absorbent filler.

With this we have an absorbant membrane that (if dense enough) can support the weight of the juice. Unlike other mods, the addition of the spring holds the filler in place near the atty leaving the rest of the cavity empty. Now the juice has a predictable direction of flow, it will always gravitate towards the small amount of filler near the atty, since that is the only absorbent material present. Also, due to the reduced amount of filler necessary there is less 'waste' or un-vapable (if thats a word) juice, which we all experience when any other filler based mod is used.

Different carts will need different densities of absorbent material due to the size of the opening. For example, a reservoir with a narrow opening will require less material than a res with a wider opening (think about when you put your finger over a straw in a glass of water and the liquid stays in there), given liquid of the same density for each. Likewise, a more dense liquid will require less material than a less dense liquid.

The less the filler or absorbent material used that is able to hold the juice while still preventing leakage will lead to the best results. This is the closest to that model we have seen thus far.

The greenie is made of nylon fiber. I don't think the straw would get hot enough to leech anything into the liquid. I don't think it would get hot at all.

I haven't touched my 510 in months....thought what the hell, give this mod a try. Took a few minutes, but damn, a mod that actually works for once.

Good work!

After 2 full days of vaping on it (5 refills on a penstyle), my RN4072 atty went cold It was maybe a week old. I am not sure if the mod doesn't keep the atty wet enough to run at 6V, or if I just had an atty that wasn't going to live a long life. I got great vapor the entire time, but I did get the dry atty taste every 3rd or 4th puff in succession. I did find a way to work with it. I would take a couple of quick 1 second primer puffs, to heat the polyfill up, then it seemed to provide sufficient (?) liquid to the atty.

I will continue to use this however for 3.7V vaping, it works pretty good. I don't know if there is a good substitute for dripping at 6V, you really have to keep the atty wet. Perhaps I'll give this a try with my 5V passthrough, and see how it does.

Oh, and this has been the only mod to completely dry out a cart. I look at the polyfill and it's white, then pull it out of the cart, and there is no liquid inside. What a wonderful sight to see

I agree it won't get hot at all, but that is not my area of concern.
Things can still leach stuff into liquids they are sitting in, whether they get hot or not.

As an example, I can not drink bottled water if it has been opened for more than a day.
It starts to taste like plastic.

Ingesting whatever might leach is not a big concern for me.
Vaporizing whatever might leach is a concern though, because that changes things.

In the end, it is not a BIG concern for me, but I would like to know for sure.

if the material concerns you, try the depots rubber cap. thats already in touch with the liquid from the manufacturer.

were that the pictures kristin could not see ?

[WarrLordd]

Didn't real all post on this thread probably only 2 first pages..

But i just finished making mines for m401 ..

I'll post updates later

[kreiderb]

This has been working really well for me.
