eclypse, I think the real problem is that a sort of vacuum is created after the first few drags. I noticed that I had a cart that was a tight fit and that cart would never work well. I remember seeing a mod where there was a small hole drilled into the cart about half way up to allow air to flow in. I'm gonna fiddle with an idea that allows air to equalize the pressure.

After trying this a while, it definately allows the juice to flow. The only issues are that a tiny bead of juice collects where the hole is and the draw lightens up a bit (this can be fixed by covering the hole with your lips). I used a safety pin to make the hole. The trick would be to make a hole small enough for air to pass but not juice. I believe this can be done.
I'm going to see how tiny a hole I can make.

Yeah i know all about traped air as i've done a hole in the side of the cart before for use with polyfil.

510 cart vent mod.. Polyfill works great now!

I also tried the cart i have with a tiny hole at the very bottom.. its a real small hole.. i cant remember the exact size drill bit as i threw the package away it came in but i think its 1 16th of an inch. I used that mod to hold a tooth pic inside the cart to help bridge the slug and to give another wall for the juice to flow off of. Tried that with both a slug and the full slug and it leaked pretty damn good hehe. Maybe i'll try a smaller hole as i have a few carts from the last mod with the side vent that are pretty small.

Also so far the deeper slug so far seems to be working.. though i need to sit there and puff down the whole cart at once to see forsure.

I've got so many different slug variants in different carts its tuff to remember whats what till they run dry and pull them out to see.

The plug post #333 been working great for me

the slug post #333 I haven’t found the right size yet to make me switch from the plug I haven’t given up though

great pics post #333

great pics of the 510 post #251
this is what I eventually would have done myself but would never have done this good of job.
Thanks for all your efforts you saved me a lot of unnecessary hassle.

kristin great link great pics post #440
the straw mod saved me when I first started vaping . I plan to revisit this mod as per your instructions. I only just started the PTB when I found the plug mod and have been happy ever since. Thanks for all your efforts and your posts.

Hold off on using the Blue foam on a High Voltage device! I've just noticed today that the very edges of the slug are burnt. Little black spots on the very edges.

:( Might just be the fact that the slug edges are too close to the coil. The plug might be the fix but still worried about it.

:(

:(


I have another idea that i'm working with that will fix the main issue with carts. Now i just need to find another plug.. Working on that as well! hehe.

I have an really neat idea for a plug as i've been playing with it the past 2 days. Will see how it turns out.. though i'll tell ya everything i think about someone else seems to post it before i get a chance! lol... well something close enough to make it look like i've some what coppied the idea. Kinda makes you wana just stop trying.

Updates are gona be slow the next 3 days as my wifes Father pasted away yesterday evening and the wake is tomorrow and the Funeral is Tuesday.

EDIT: Er wait.. if i release mine to the public, scottyballs will just use the design to fix his newest work and sell it.. so maybe i'll just do this right and talk directly to Joye about the cart.

Looks like an interesting mod. Before I go to the trouble though, has anybody tried using it on a high voltage cig (say 5v) like Prodigy et al? I just switched from a Titan to an Xhaler and think it's great, but I'm not a dripping fan. Polyester burns, so I have to drip. Do you think this stuff will stand up to the heat?

Try the plug first.. If you dont see black spots (burnt foam) then your good.. Only the very edge gets slightly burned. Thats cuase with the slug mod version its longer and its alot closer to the bottom of the atty where all the high heat is from the coil. Thats only with high voltage though.. Mine 6 Volts.

I might try a shorter slug so it dont reach along the sides of the bridge.. then again i could just go with the original plug. Then its far enough away from the hot coil.

I'll try that now and report back shortly.

OK, I have returned to testing with the blue plug. I haven't had complete success with the PB material at high voltages. I've been using the mod all day with very good success. I'm using a straw from Sonic which is 6mm in diameter, and I cut it to 14mm lengths. I cut the straw length wise and removed about 1/3 of the straw leaving a big gap in the straw length wise. I also cut a V notch on the side opposite the 1/3 gap. Curling the straw tight with the tweezers I can reduce the diameter and still leave a full length gap in the straw to assure free flow of liquid so that there are no areas where the liquid can become trapped.

I took a piece of the marineland blue foam and cut a piece 5mm wide by 7mm long. I folded the foam in half with the tweezers and inserted it in the top of the cart after filling with liquid. I've been using this with my Prodigy and PS PT with good success. No leaks even though I have been using commercial PG liquid.

I took a page from eclypse's discovery on the best method of getting the liquid out of the reservoir. Since we have no natural wick in the reservoir we need to keep the cart veritcal in order to keep the liquid in contact with the plug. By doing that I eleminated the cart leaning out and the harsh taste (until the cart goes dry). This has good promise to a reliable configuration. I will be working on how to get the omni-directional wick action without giving up the reservoir space.

a2dcovert, you want to keep it on a 45 degree incline to keep the liquid at the plug... well that will help.

I have a new working mod that i'm toying with atm that will help with keeping the air out of the tank. Its a air pressure release value. hehe.

Please revist my old mod.

What you want is a very tiny hole in the side of the cart. Just one hole as small as possable.

Now, take one of those clear caps that the cart come with and cut the end off. You'll now have a sleeve. put that over the cart and have it cover the new hole in the side. it would be smart to somehow mark where the hole is on the sleeve so you'll know.

With the sleeve now covering the hole on the side of the cart, fill the cart with juice. Add the slug or the plug <-- Loving it right now with HIGH VOLTAGE! :)

Vape away.. when you get the slightest hint of dry atty, slightly slide the sleeve up to expose the hole in the side of the cart. When this happends the traped air will be removed from the cart and the juice thats stuck in the top will drop real fast and the plug will be super moist. Just be quick about it or you'll flood the atty real quick. So just expose the hole for a sec only!

Then continue to vape away!

This is the perfect quick fix for those that would like to chain vape.. Prob not nessisary for those that vape a couple of puffs and put it down for a bit.

I dont think you can do a straw with this but let me know if you try it and it works.

I've been messing with that since last night as i've been trying to get something to wick fast for high voltage devices.

Oh.. still playing with it but i think i may get this to where you dont have to move the sleeve. I've managed to cover the hole with a corner of the sleeve. Or hard edge of the cap/now sleeve hehe. Doing so keeps a very tiny air gap so air can leak. I believe thats whats going on as i've yet to have to move the sleeve to keep it wicking and i'm now on the 2nd refill.

NOTE: When you move the sleeve to let air enter the hole and cant find the hole, try to keep the cig level as you moving the sleeve. That way you dont have all the juice fall out as you'll have the hole exposed too long.

Dont use your best juice while your learning how to use this as you'll probably flood the atty once or twice till you get the hang of it.

You could call this a true auto drip mod as thats where i'm gona take this soon.. Dripping without having to grab a bottle of juice hehe.


Every cart filler and even a plug traps air in the cart traping juice... the old straw mod helped as long as no juice got in the straw to plug it up.

P.S. If your really daring you can uncover the hole and just fill the cart by dropping juice right on top of the plug and it will now soak threw.. its just tricky as you'll want to angle the cart with the hole facing up and hold it at a 45 degree angle while your dripping. you'll want to keep an eye on the hole as to make sure no juice is coming threw.. though its just best to remove the lug and fill as usual.

Just got done chain vaping nhaler's HV Cafe Mocha Tobacco at 6 volts and .......N IS THAT AWESOME! Its better then food! heheh. Plus i dont even drink coffee.

Chain vaping with the original plug and the air pressure value release fix is awesome. Only got to do the air pressure realease once to empty the cart dry.. Pull the plug and all you'll see is vaper down in the cart bottom! :)

Using the shotgun slug @ 5v on a 510 with the hole and sleeve fix for airflow for about 2 hours now, chain vaping. Working well, no flooded atty and I've only moved the sleeve/ring once or twice. No burnt taste/dry atty, and lots of vapor consistently. I also cut the foam so it is only half as thick as it came, don't know if this helps or just the hole in the cart, either way it's working.

The ring doesn't look very good so I probably won't use it when I'm out or at home, I still prefer dripping or topping off so I only have to carry one cart and can change flavors easily (I have a short attention span :D ) but this will definitely be used when commuting to San Francisco. No more topping off in traffic, thanks Eclypse!

Hi, y’all,

I’ve been following this thread with great interest, and have tried to keep up with the mod variations as best I can! Tried the plug, slug, shotgun slug, tried the straws. Passed on the paper clips. Here is my experience: Eclypse, I think you really got it right with the first mod. I think you were right, the search was over. I REALLY admire your creativity and resourcefulness; it’s been interesting to try the variations on the original mod. But I, and 4 friends in this area, have all consistently gone back to your first simple version of the blue foam plug. I don’t even measure the foam, just eyeball it at the length to the lip on the 510 cart (or less, length doesn’t seem to matter as much as width), cut it SLIGHTLY wider than the width of the cart. Vapes perfectly, every time, no flooding, and it’s really easy to taste when I need to refill. Slightly dry, burning taste, and the plug is moist, but the cart is dry. It’s just perfect. It works just as well with the 510 bullet tips. My friends are reporting the same. Three weeks using this mod, I can’t imagine anything better.

But, an inventor is an inventor, I’m sure you’ll build a better mousetrap, and maybe even a mouse to best it! And I’ll stay tuned to you for SURE. Thanks a zillion and a great big hug for a mod that’s working perfectly for a little group in central Virginia.

Nice! yeah i gota find something better looking for it.. Oh wait.. A cartomizer cover would work perfect for it.. though i'm sure we could just cut the one now a little neater. I did find out that you can just slightly pinch the sleeve as it slightly lifts the cover from the hole and that would be good enough to remove the air pressure and the remaining trapped juice will drop in a hurry.

This is only needed for those that like to chain vape the cart dry in one shot.. for everyone else its not needed as the juice will drain down to the plug durring the down time.

But for those that use high voltage and vape it dry this works perfectly! High voltage eats through juice in a hurry alot quicker then the cart can re wick.


I'm not cutting holes or adding this or that. The only change needed to the 510 cart design is the filler. I did start seeing leaks this morning so I am rethinking the filler again. The blue foam doesn't hold it's shape very long, it seems to break down either by heat or the liquid. The search continues.

Maybe one day i'll make a quick video showing how the juice will hold in the cart upside down.. and what happends when you have the hole in the side of the cart.

Maybe its just your custom juice thats breakin the foam down??? I never have a prob with the foam.. infact i'm still using the original slugs i first cut long ago!

I bought the Marineland foam, but bought the V version instead of the U version. They seem to work pretty good, better than PTB. Has anyone else got the V version? It was all that was left at Petsmart.

Funny you mention the V version.. I was at the store the other night and i noticed that the Meijers i shop at has the marinland foam.. i thought, cool! A place i can goto thats open 24 hours a day that sells it. Then i noticed they had every version but the U version. :( I dont know if they dont carry it or everyone bought it up! hehe.

Anyways.. more importantly, i noticed that all of the versions were not the same foam filter.. its like fluval. A totally different filter thats not even close to the blue foam. I'm sure it will work good though.. i dont know if that will work as a plug though.

You can buy it here as wlel just encase you cant find it locally. Marineland Rite-Size U Bonded Foam Sleeve

Great to hear! :)

Yeah just the other night i tried the original plug version for the first time since the slug and wow it does work great! hehe.. Cool to go back and try after messing with other versions so much.

I now use the original plug for high voltage period!

Well, I'm not giving up on any of the great mods being invented every day aound this forum. I still think there is use for the blue sleeve.
You have a 'T' you tried. Well, I am trying a 'L'. ( you may have done that too). The longer end is thin and fits inside the straw, the shorter slightly thicker 'leg' is the plug that sits on the straw. This is working better for me as it is more stable, stays in place and have gone thru a full cart without floods.
(using a 510 w/ round & flat carts)

That makes 3 mods in various carts that all work to varying degrees: blue ,ptb, cart condom cut-out

Thanks All, keep inventing !

No video needed. I'm not modifying a perfectly good cart design. The air evacuation was perfected long ago by the straw mod. The straw not only holds up the plug, it also evacuates the air from the bottom of the cart. Use the straw and you wont need to butcher your carts. No air trapped in my carts.

I'm not using anything exotic in my mixtures, just PG nic juice, VG, flavoring and about 10% PGA. I also noted the same issues with the commercial PG 24mg Virginia juice. The foam will go limp and compress down. The PB material does the same it just lasts longer. It's problem is it is too stiff at times. It depends on how thick the plug is.
