Actually, since sqirl1 was looking for something unlike a syringe, the
Bottlefillinator would probably be more up their alley. It's basically a bottle with a Luer Lock cap that's been modified with a drop tube so the bottle can be squeezed to get the nicquid up to the top of the cap, where a modified female Luer
threaded adapter feeds/fills the cartomizer.
Feel free to check out the video in the link (there's also a Bottlefillinator filling test video on YouTube), but please IGNORE the parts about constructing the female luer adapter. That a was a long, tedious process that produced a relatively unreliable part.
Instead, the new syringe adapter for the Cartomizerfillinator V2 does the same job and is MUCH more reliable and easier and cleaner to build.
The ONLY problem with the Bottlefillinator that I haven't addressed is that the two-party epoxy that I used to secure the drop tube to the polypropylene body of the Luer Lock cap can, if stressed enough, separate from the cap. So I really need to find a better epoxy or adhesive, and I'd also like to replace the stainless steel needle tubing with some kind of flexible tubing.
In any event, I could post some pictures of the Bottlefillinator with the new adapter sometime tonight, if anyone is interested. ...
