Borrowed some ideas from some of the very talented modders that frequent the e cig forums here and elsewhere. I am not trying to steal any thunder from anyone else who has had these design ideas already. I am simply offering a way for others to produce there own version of some of the mods created here and elsewhere. This is a 18650 battery mod with a ptn05040 TI voltage booster. there is enough room to add a juice bottle feed system which I am planning to add eventually. I am also planning to finish off the body and end caps so that it looks cleaner. A little body filler and some paint should clean the body up nicely and give it that manufactured look. Anyone with some modding skills should be able to reproduce this by looking closely at the photos. This unit will last for a full 24 hours of heavy vaping with a 510 atty. If you plan on using this plan make sure to get a battery that can handle the current draw. I am using an AW 18650 2600 mah. AW makes excellent batteries and I personally would not recommend using anything else for this project. Order 2 batteries and you will only need to swap them once a day. IMG_8625.jpg

Nothing elaborate. Same as everyone else. A cut out on the side. Can't really improve on that idea.
You can, but it probably isn't worth the trouble. :D Off the top of my head, I can think of three potentially more elegant (if definitely more complicated) systems.

  • A spring-loaded ascending plunger with a valve at the top. Pull the plunger down to compress the spring while you load the juice, then release the plunger. The spring pressurizes the liquid, and when the valve is opened, juice flows out the top to the cart tube.
  • A squeeze bulb with a one-way air valve. Just like the priming bulbs on small engines. Pressing the bulb on the top of the mod forces air into the juice chamber, which displaces the juice out the cart tube.
  • A plunger with a threaded rod and twist knob. Works like a deodorant stick. Twisting the knob twists the rod, and the plunger moves upward, pushing out the liquid. Damned if I know how you'd create a good enough seal around the threads to keep the juice from leaking, or keep the plunger from spinning, but I'm sure someone could science it into existence.

Again, I'm not saying you should do something different, but just that there are other options.

Nice tornado...what did you use for the two tubes?



3/4" CPVC from Lowes glued together. Drilled through the inside with a Drill Master 44460-0VGA step drill bit from Harbor Frieght. Cut one piece in half then glued to the sides and grinded flat.

Is that schedule 40 or 80? I was thinking about getting some 80 because the ID of 40 is .824" and 80 is .742" so the 80 should be a nice fit for a 18650 batt.

Not sure which I had. I had to drill the inside to fit the battery. If I would have found something that I didn't have to drill it would have made it a little easier.
