I've been tweaking this one on my 901 and I think I have it now: No straw, push a half sheet in from the center and trim so that it is just below the top of the cart. The trick to getting it "right" is making sure to get the correct length and having it bunch properly... sorta like an upside-down closed umbrella. Sometimes I have to insert the PTB several times to get it to bunch correctly.

I'm going to try this on my 401 and see if I can make it work. :)

Good tip Theaxiom. If anyone is having that issue, it should help. I haven't run into it though - it usually fills up easily.

I keep switching back and forth between this mod and the RSP mod. I currently have this mod in all of my carts - it's just easier to make and refill than any other filler mod I've used! :)

I've tried this in the 510 with no straw and it leaks or floods the vents and you get liquid in your mouth. Good to hear it works well that way in the 901!

As far as trimming - I like to have it flush with the end of the cart. That way, when the atty bridge pushes it back, it doesn't go back in too far and still makes contact. You definitely have to have it bunched correctly - too big of spaces and it floods. If you have it right, it never floods and gets a bit of a recess in the middle, with the outside layers staying flush with the cart end. It sort of wraps around the atty bridge perfectly!

Hi Kristin,

I still haven't been able to find a local source for the tea bags. I don't know why this is the case. Maybe they don't figure Louisianians drink that type of tea? Anyway I haven't been able to try this mod.

I don't know if you modify your liquid or not, but adding some VG to your liquid would help with the leaking. Liquid viscosity effects cart performance and in most cases the thicker the liquid is the better it is at leak control. I make my own nic juice and have good luck controling the viscosity of the final product. Some of the commercial nic juices are very thin and runny.

I think you can buy that material in a shop that sells fabrics and stuff for making clothes but I don't know the name of the tea bag material

I primarily use HV from nhaler - it's pretty thick. I don't really get leaking with this mod.

You can get the teabags here: LIPTON Online Store

I live in a small town and the Walmart here carries them: http://www.walmart.com/catalog/product.do?product_id=10535894

The fabric is called "gossamer." Maybe you could get some from a fabric store? You could get it as a ribbon, too. Usually used as wedding fabric.

kristin,
Whats the purpose of the straw in your PTB mod? If the PTB was pushed into the cart without the star would it work the same?:confused:
It actually serves a couple of purposes:

1. Helps keep the material close to the bridge, without it, it tends to get pushed too far into the cart after awhile. It sort of "holds up" the plug end.

2. It allows you to use less material, by narrowing the space & holding the thicker part at the end. You can get two carts out of one tea bag. Otherwise, you'd have to use two bag pieces to avoid leaking.

3. It holds the smaller part of the material in the cart, narrowing it and allowing the "flowering" effect at the end to envelope the bridge and open enough to plug the cart and lessen leaking.

4. Less material in the cart to hold the liquid back, especially with thicker liquids and you have less material in the bottom, allowing the liquid to flow more freely. Otherwise you'd have to use two pieces and that holds liquid, causing more topping off and less flow to the atty.

I did try it without the straw and it leaked a lot and the bridged pushed it back too far - it's not stiff enough to hold up against the bridge by itself. I tried using the whole tea bag to counter that and it was just too much material. It held on to the liquid.

The less material you can use, the more liquid you can get in and the easier it'll release the liquid to the atty.

Like other PTB mods, this does eventually gum up and start holding liquid. Unlike those others, it takes longer to get to that point (less material & folds) and is VERY easy to pull out, rinse, dry and put back. It's hard to do that with something that has been rolled, folded and shredded all to heck, lol. The straw never really had to come out once it's in place.

There shouldn't be much to adapt? Is the 901 just longer and more narrow? It should still work. You may not need the straw, if it's more narrow.

I tried to take the inside stuffing out of one of my 51 carts pulled the wires out with it. Try to post a picture of the inside of it here. hmmm not very big picture, anyway the wire comes up inside the material then down the outside. Ahh i see if you dbl click on the picture it gives you full size.I see no way to use any other material in these

Thanks kristin for sharing, tried it and it works great for me.

Already on the 3rd day vaping it and it still wicks fine, still taking at least 10 drops on a refill.

Worked from the first try and with great results (been using the loosely rolled double fold before, could only refill with 7 drops at most).

Just a note on this. I made up a cart and figured if the notches in the bottom were good, then more notches would be better. So I notched the SIDE of the straw, too, about halfway up.

Don't! It completely messed up the wicking. It worked worse than straight ploy-fil. The sealed straw seems to actually direct the liquid - so don't add any side venting on the straw!

Second tip - try snipping litle cuts in the end of the PTB on the atty end. Just like the rolled/frayed PTB mod, it opens up the "flower" more. But, just little 1-2mm cuts - not all the way down. Since it isn't completely frayed, it still comes out in one easy piece and rinses easily.

This is still my go-to filler right now. (Still have to get some of that darned blue foam to play with...can't...stop...modding...)

First of all, as a brand new vaper, I'd like to thank all you veterans for providing us newbs with great info. I wish I'd found this forum before I ordered my first two kits (blu and green smoke, both of which have issues, though the GS is by far superior IMO). Oh well, lesson learned, and I'm lucky enough that the loss of the money doesn't hurt me that much.

Do you think a variation of this mod would work with l88b carts? I'm trying to get better performance out of my blu until my 510 gets here (parts coming from China, so it'll be a while). I have some puresmoker liquid (and some reduced PG on the way from JC), but the tiny inner carts of the l88b make refilling messy and difficult. I know the blu atty protrudes into the cart farther than many, so I'd probably have to trim the straw and PTB shorter. Thoughts?

I honestly have no idea, because I only have a 510. You'll have to try it! :)

I just tried this tonight (my first-ever mod), and it worked perfectly.
I followed the directions exactly, with no problems. I'm a newbie, so I haven't compared a lot of different liquids yet, but for the record, I'm using liquid from VaporStation. I stopped at 10 drops to be safe. No leakage, no flooding. Already much better than the poly. Thanks, Kristin !
