I'm a newbie with a few posts under my belt and about 5 weeks work of vaping. I have read a lot about different cart mods and they all seem to be about finding a better filler.
What I'm wondering is if anyone has a good working knowledge of fountain pens and would it be possible to modify that design to deliver liquid to the atomizer. The cool thing about fountain pens is you can place a liquid filled cartridge which is what I would love to see in an e-cig.
Just a thought.
An excellent thought, Kreiderb! I'm a noob who hasn't even tried PTB or straw or any mod yet, but this sounds like a fabulous suggestion!
I have several fountain / calligraphy pens myself, and dozens of little cartridges of ink. These cartridges are sealed, cylindrical plastic tubes of ink. To use, one pops them onto the top of the nib (pen's writing tip), which has a metal tube or "straw" sticking out of it. The metal straw is angle-cut at the end, and inserting that straw into the ink cartridge is not unlike popping one of those little straws into a box of kids' juice or a Capri Sun. The act of inserting breaks the seal, and the fluid travels through the straw only when pressure is applied, as in writing; but suction should bring the liquid through as well (as with juice boxes).
The primary hurdle to tackle would be, how to break the seal and direct the juice where needed. Also, it's important to consider that once the seal is broken, the juice would likely dry up/evaporate if removed from the PV, unless there would be some way to re-seal the cartridge. So that would need to be addressed, or be prepared to vape an entire cartridge of flavor X (which may take quite a while, if I'm picturing the same kind of cartridge as you).
See
#2 on this page to get an illustration of how these ink cartridges work. The metal "straw" atop the nib is not shown, as it is recessed inside the plastic barrel attached to the nib itself.
Also? I can see this for 510s, but I'm not sure how this could work for 401s, etc. 510s have that recessed atty (much like the recessed nib tops for the writing pens), but not all PVs are recessed like that. Perhaps another design using similar ideas, but modded in a different way.
But I just love that you made that ink cartridge / e-juice supply idea connection. THAT would be a mod I'd be very excited about! Would love to see ECF members and also e-juice vendors tackle this idea and start manufacturing cartridges of juice.
