Reservoir Straw & Plug Mod (RSP Mod)

[PixieCut]

How well does this (or the paperclip variant) work for 801?

I have been messing around with variations of this mod with an 801.

The paperclip was not working well for me. The paper clip kept slipping to the side, the plug would shift and I would flood the atty.
I used several bad words each time that happened.

The straw holds the plug (I am currently using the blue scotch pad) in place but I am still working on dimensions to get better wicking of the juice. My current plug is about 4 mm. I think it needs to be thinner though, and the straw longer...

(I have tried lambswool and the original cart stuffing as the plug too, with limited sucess.)

I believe it has the potential to be great mod for the 801 cart once the nasty little details are hammered out.

If you need any straws or the scotch pad, let me know-- I'll ship it to you MPS. The commissary here has both.

Let me know if you have any success with it!

I had problems with the original stuffing and slow leaks (atty is vertical most of the time), so I went to dripping.

While I don't mind dripping, there's been times it would have nice to just be able to quickly swap out a cart...I'll have to look and see what they have at the PX, here.

I just got my first 801 atomizer today in the mail! So, I'll let you know what I come up with. The RSP, blue plug, and ADM-PC are kind of building on a design that replaces just plain poly-fil. It delivers a constant flow of juice that comes very close to dripping directly on the atomizer. Better flavor and it drains the liquid down to the last drop.

Here's Scottyballs' original video that does a great job of demonstrating how much different it is from a regular cart.

P.S. If size matters, the 801 is king. The atomizer (with cart) is almost as big as a regular 510 battery!

I think I've had an epiphany!

I know I just posted a note late last night, but I've slept since then. I was having my morning vape and waiting for the coffee to finish. Looking down at my stuff--cut up straws, half mangled paper clips, and such--I was thinking about the paper clips and thinking I really want something plastic. I also kept thinking about Kristin's straws and the shapes of her vents. Kristin's cuts take a very logical approach--which I love--because you have to find the ultimate balance to create support and flow. Then it hit me. I was factoring in everything about the carts and plastic and support and everything I've learned so far.

What I came up with is a plastic rectangle. The width would be the diagonal length of the cart bottom. The height would be just to where the lips of the cart are. You want a very thin plastic sheet. I have some stickers and the plastic it comes in is great. When you slide the plastic rectangle into the cart you end up with a support brace that cuts the cart in half diagonally. You've got support and flow. Then you can easily cut a hole at the bottom and/or one at the middle to allow air/juice flow.

As always, I have time for the idea, but not the application. I whipped together a quick diagram. I haven't tried it yet or have any dimensions, but in my mind's eye it should be absolutely perfect. Support and air flow. Somebody give this a go and let he know what you think.

​

It basically divides the reservoir into two chambers and provides a center support system at the same time.

Look good?

--Prof Daffy
P.S. Now I just have to find some thin plastic I can cannibalize and make a template.​

Geez, Daffy. slow down. I haven't even had time to try your latest straw-strip variant!


I still like the idea of finding *something* like the straw-strip that will have some springiness to push the filler into the bridge. It seems that every filler we use "dies" and goes limp after a while. It would be great if the strip pushed the filler, in order to counter the effects of the filler going limp over time. I'm not sure that a drinking straw has the required springiness, though, since it's so thin.

But now this idea of thin plastic might have some merit. Not too thick, not too thin, but something strong enough to act like a spring. Maybe something like the plastic used in packaging, like when you buy something with a clear front glued to a cardboard backing, if you know what I mean... Or one of those plastic covers on cheap school ring binders (that might be too thick).

Ok guys, here is a link to my latest cart mod - give it a try!

Starting another experiment with straw and analog "roll your own" filters.

I cut the straw in that way so I could bend the long strip over the top end of the straw, like this:

This way, it acts like a spring, pressing the plug on to the atty's bridge.
This is how it looks like when full with 8 drops of liquid:

I cut the plug using a circular tool I have which, luckilly, is just the same diametre as the M401 cart

Just trying my first cart set up like this, but it seems promising. No more plug going into the straw at least

 

[Nietzsc]

hahaha, this is insane!!! talking about junky behavior... all this cutting and folding, stuffing, pushing, pulling and bending brings me back to my María Juana days... Great!! keep it up...

And by the way, I looove when someone post pics of what they've done

Anyway, gave the analog filter's idea a rest. Original polyfill as a plug works better. The filters are to dense for the work and doesn't give a consistent experience, although it rocks when working properly. I kept the straw design and it is a more confortable solution.

The analog filters seem at first to be a good option. But they are more dense than the polyfil and they don't hold up too well. I wish they worked because I have thousands of them.

Just gotta say first that I've been lurking here reading up on all you guys great R&D work waiting for my first PV order to arrive.
Now I'm 5 days analog free with a working mod on 6 carts so thanks to everyone on this thread

ProfessorDaffy's plastic wedge has worked a treat for me in the following way ...

My Kit :
Std Janty Stick ...
Eastmall 801 soft tip carts ...original polyfill (not sure if all makes have the same type of polyfill)

Plastic wedge : ironically is the plastic box my Buff Puff came in !! Its made in a carboard box type fashion (folded) out of acetate sheeting somewhere about 0.5 to 1 mm thick.

The original carts polyfill was used in the following way :

1) Removed it
2) carefully snipped off a small dob of silicone sealant that was holding it in the cart.
3) gently flatened it out so I had a thin rectangle 25 to 30 mm long
4) cut in half length ways so now you have a strip about 5 mm wide
5) roll it up length ways so you get a spiral or 'swiss roll' plug
6) place the swiss roll in the cart so you would be able to see the spiral


No leaks ... no floods .... and good vaping till the carts empty
(35 drips in empty cart with dry polyfill ~ 25 drips in empty cart with wet polyfill)

Just bear in mind this hasnt been field tested ie ratling around in a pocket whilst you run down the street but as an at home / office / on the sofa kind of thing its working perfectly

 

[kristin]

Well, the biggest issue with this RSP mod has been finding the right plug and I think it's finally been found! Using the straw/reservoir principle, Scottyballs has come up with a great 510 plug, just using the silicone cap that comes on the carts!

I've been using it and I think it could be the best plug yet. You just need the straw, scissors and an exacto knife. You'll also probably want to buy some needle-tip bottles for refilling. Check out this mod to see the result and a link for the bottles ($2.99 for 6-29ml bottles)! http://www.e-cigarette-forum.com/forum/cartridge-mods/53487-zfm-zero-filler-mod-12.html

I love the plastic wedge. Actually I loved the ADM and Paperclip version, but I hated that slight metallic taste. And it's easily adaptable to whatever kind of filler you want or whatever height you want. Glad to hear it's working for you... and me!

I just bought a pair of tweezers at the dollar store (with the ADM it's all about the tweezers) and the plastic package will become plastic strip mods.

Kristin's right there's a lot of ideas flying around on the No Filler Mod thread.

Time to bring this back up. I still have been experimenting with the RSP. Here is a picture of the straw I have been using for several days. The straw has a diameter of 7mm. I cut out a piece of the straw along the length removing about 1/3 of the straw. Here is the picture:

I left the cut piece in the picture so you can see the amount of the straw was removed. The reason for the cut was to reduce the straws diameter so that it would fit into the cart and to eliminate the possibility of trapping liquid or air at any point of the cart due to the straw. The vents cut in this version allow liquid to move freely within the cart. The length of straw I am using right now is 14mm. This allows you to use a 5mm plug and have 1mm clearance to the atty. This length can be adjusted any way you wish. It's hard to create a one size fits all design because we are all not using the same viscosity fluid and there are a big variety of battery units. My cart is used for my 510 PV at 3.7v, 4.3v, & 5.0v. I am using this exact configuration right now on my Protege at 3.7 volts and slightly thick juice. It performs very good during vaping but sometimes has an issue of the plug staying in the atty when I remove the cart. It doesn't leak at all, the wicking is just right, and can empty the entire cart without putting out that harsh taste. Your experiences may be different than mine but I encourage you to try one of these reservoir plug mods. The quality of the vape experience is tastier and last longer than the stock filler material and you don't have to top off.

There are so many different possible configurations of carts and PVs that you may need to experiment to get the set up right for you. What's important is that the mod works for you and your favorite configuration.

This "straw", in general, has the added benefit of keeping the liquid in contact with the filler (wick). There are many different types of "Straw" material out there. It doesn't have to be a straw, just so it satisfies the design of creating a reservoir.

This is an awesome mod! For those who are looking for something with a minimum of fuss and don't want to constantly experiment, I recommend using this mod.

I cut the straw as indicated (supermarket flexi-straws fit perfectly), and I use Aquaclear Foam inserts. A 3-pack is about $4 and will last for at least six months, maybe longer. The foam is white--although on the box it appears yellow) and it is cut as a 3"x3"x1&1/2" cube.

I just cut a piece off, trim it so it is a 1/2" square, and stuff it in the cart. I fill to the rim of the straw, and do not prime it, as I get flooded attys and liquid in my mouth when I tried that. The cells of the sponge are big, but in the cart they crush small, and work great. Also, some of the material always seems to go down into the straw, which makes it wick perfectly.

If it doesn't draw easily, I just pull a little out with tweezers and trim. I find it is better to start big and trim than just trying to get it right the first time.

Now I go about two hours on a 510 without having to refill. It works with the flat tip carts as well as the round. I encourage anyone who is less than happy with polyfill to try this. I think it is perfect.

Glad to hear that you are having success with this mod. I'm still using the puff buff pad in my carts with very good success. You are right to make adjustments as needed. One size definately does not fit all. Here is a drawing I made to assist anyone who needs it. To have success with this mod you will need to be able to repeat the cart construction by using specific dimensions.

This should help in the design of a mod for a 510 cart.

Today I came back to this mod, with the blue scrubbie pad, but I turned the plug SIDEWAYS, to allow it to work more like the buff puff pad. Much easier to set up than the BP. This time I cleaned it really well, soaked it in Polident and rinsed it again after cutting. So far, no flavor issues! I think this is still a good, reliable mod!

I may have to try that filler material but I'm still having a lot of success with the PB material. I have been using it with great success with my juice, which has about 30% VG, using a 14mm straw and a 5mm plug (dry). The plug will compress down to about 3mm after use. This works just great. I have to be careful near the end to stop before the vapor drops too low. A couple of times I have not only sucked the cart and plug dry, I've had to reprime the atty. With commercial PG juice I have to cut the straw a little shorter and lengthen the plug.

This, and any cart mod for that matter, may have to be modified for individual use. There really is no mod that will fit all combinations. Adjustments to the straw and plug size and material may have to be modified.

Just tried this mod and it's fantastic. It's been over an hour and I haven't had to top off and the vapor is still strong as ever. Finally I think I found the mod that's gonna work for me. Thanks so much!
