New thought on cart/refiller MOD

[Primulas]

I have been looking around at alot of the cart injector mods around. Most seem to involve a small bottle or dropper mounted to the ecig.

I got to thinking what the problem really is for refilling carts(for me anyway.)

The things i hate about refilling my carts(especially on the go) are:
1. It looks kind of "shady" when im at places like work and my boss is around(i refilled my cart a few days ago in a nice restaurant...was somewhat embaressed.)
2. Getting juice on my hands...and/or having to clean juice off the cart with paper.
3. Not being able to fill on the go easily(or without "tools")....for example in my car...or in a grocery store.

I don't really need the juice delivery system attached at all times to the ecig.

why not drill a small hole in the cart, mount a small self healing injector port into it(like for drawing medications from vials....a dot of soft silicone would even work.

Then just design/mod an e-juice bottle with a small needle(just long enough to clear the port) and a pump or squeeze action that allows 1 or 2 drops per pump/squeeze. Could even make it screw into the port or snap in. Also a pushable sheath could prolly be added to the bottle so the needle is not exposed unless it's against the port. A substitute for a metal needle might even be possible.

I don't mind carrying juice....im going to be carrying extra parts regardless(if nothing else an atomizer.) If i could just snap my bottle onto the top my, cart give it a squeeze/pump, and be on my way i'd be plenty happy.

The only problem i see is how to get the dropper to attach to the cart near the atomizer, since most carts slide inside the sleeve of the atomizer(my 801 does anyway.) Possibley placing the port directly through the atomizer casing? sounds like a lot of work(not to mention each atomizer would also have to be modded.) Also that would mean the cart would have to be inserted so the holes match; That's not a terribley hard problem to fix...but not ideal.

Any ideas on a simpler way to get the injection port near the actual atomizer coil? Is that even necassary?

It's not something that is within my lackluster mechanical skill range. But it seems to me that it surely has to be easier then a mod with the bottle actually mounted onto the ecig. Not to mention for me personally i'd like the ecig to look as unmodded as possible for public use.

Anywho to all of you mechanical types...what do you think? Am i missing some major complications?

It wouldn't need to be near the coil - it IS dripping, after all. Gravity will get it there.

It's not a bad idea - it could work pretty much as you outlined it. Personally I'm a fan of having a weird little self-contained box with buttons and pumps on it so it isn't for me.

It would be nice to use the little opening on the end of the mouth piece where you take a draw from. Just need an extra self-sealing hole on the inside bottom of the cart. Then you could refill the cart from the bottom up.

If your idea is to fill a cart from the mouthpiece side, we still need to find a better wicking material to actually get the juice to migrate down toward the atomizer. I spend more damn time topping off carts on my penstyle devices when the cart is still nearly half full.

Yea....that was my thought too. That's why i was saying a big problem may be getting the juice to reach somewhere near the far end of the cart. Though if the cart is not empty just the topside is and you pump more juice in it would force the juice in it already closer to the far end. In combination with DIY poly-fil wicks(these work alot better for me then the ones that come with dse carts) it may be viable. I suppose i could sacrifice one of my carts and just drill a small hole and dab some silicon over the hole and fill with a syringe to see if the premise is sound.

Kender- that might work too...just put a port on the bottom of the cart and fill through mouth piece.....though there are a few things that make it less then ideal i think. For one you'd need a longer needle to reach through the mouthpiece/cart; For my 801 it would have to be quite long...almost a regular syringe length needle. Also depending on the mouthpiece you may have to widen the opening to accomidate a needle...not sure if that would hinder the hit or not. Also it seems like it would be easy to flood your atty filling top down....hard to say for surew wihtout trying it though. An interesting possibility though. If i sac a cart maybe i'll try both ways.

Ok, so i've been messing around with this idea with some decent results.

First i modified my 801 cart. I drilled a small hole through the top of the cart mouth piece with my dremmel tool. The hole goes through both the outer and inner wall. I then sealed both holes with a couple of dabs automotive silicone. The seals seem to work good...i cannot detect any leaking after multiple piercings.

Now the harder part to produce a practical dispensing bottle. First i tried a pump mist nasal spray bottle with a syringe needle (i tried both 5/8 and 1.5 length luer lock needles) attached to the pump mechanism. This worked ok with the 1.5 length needle. This length however was not practical. Though to note it did work well, and i could easily fill my cart without removing it from my atty. Next i tried a 5/8 length needle in the same way. The length of this was perfect...the amount of exposed needle was very little(just enough to pierce into the cart really.) The problem here was that the 5/8 needle only had a 25 gauge. This proved to be to small to use with the thick viscosity of ejuice. Also it had trouble attaching either needle securely enough to the pump valve to be sturdy enough for regular and repeated use without breaking(i only tried silicone....i suspect some other type of glue/epoxy may hold strong enough.) If only i could thread the top of the plastic mist pump nozzle to fit the luer lock thread(as well as find a way to cut the 1.5 needle down to 4/8-5/8 without crimping it.) nonetheless i am not that mechanical.

So i decided to try another approach. I soon noticed that the luer lock needles fit perfectly into the inside of the tops of standard ejuice dropper bottle tops. You can just push them in and they fit very tightly and create a nice strong seal. Using the 5/8 needles works well to inject juice right from a standard 30ml bottle(like from ruyan.) Again the problem is the that it is pretty slow. It takes about a minute or so of pressure to get enough juice through the needle to get a decent amount of juice into the cart.

Soooo, i need a totally new idea of how to dispense the juice into the port. That or to find a way to cut the longer length needles without crimping them. Or find somewhere that sells 21G 5/8 length needles.

I really wish i could get the nasal spray bottle/pump to work though....it shoots almost a perfect amount of liquid. 1 or two pumps and you'de be good to go. The problem with using the the standard juice bottles is that there is no way to control the amount of juice dispensed except by muscle memory or having the stream slow enough to allow for error.

I'll continue to try things. If any of you mechanical types can think of or design a good solution it'd be awsome. It's totally workable with only about 1/2 inch of needle exposed(easily cap-able and wieldly.)

Do you have a dremel? I think the cut off wheel may cut the needle without crimping it if you are carefull not to apply too much pressure. Also, if you want to use the spray bottles, try taking the spray cup off. There's a tube inside that. You may be able to fit a luer lock onto it. Then design a way to push the tube to expel the liquid with a rubber gasket or something like that. Sealing with silicone should hold everything together. Just a suggestion, have not done this myself, like moonman, I prefer to have a reservior and pump on the go.
