The finished vapor maker.

High wattage (so-called super-sub-ohm) E-Cigs can generate a lot of vapor, but they can get very hot. The plans on this page show how to turn the eleaf iJust2 E-Cig into a vapor maker for making smoke bubbles. You can apply this design to other models but you will likely need to make adjustments as the precise measurements will differ.

The ijust2 has a power output of about 60W-80W and is not adjustable. With continuous use over a short period of time, a higher wattage e-cigs can get hot. This design exposes part of the atomizer tank to the open air to reduce overheating. This design can also work for other models with a 22mm diameter atomizer tank.

This page is a three part photo essay:

  • Part I--Building the bottom
  • Part II--Building the top
  • Part III--Putting it together.

PART I -- Building the bottom[]

The inside diameter of this piece is just a tiny bit too small to fit over the ecig--you need to hone out the inside using a drill attachment or file. The ring has to be loose fitting to allow air to pass into all of the airholes of the atomizer tank

Since CPVC cement will melt the surface and "weld" the two surfaces together you need to immediately apply pressure to the two connected pieces for approx 20-30 seconds

PART II -- Building the top[]

A CPVC elbow fitting ccan be used for the top piece. It may need to be shimmed so it will fit snugly over the mouthpiece of the atomizer. You can use a 1/2" PEX tubing or CPVC or another material or means for a sleeve.to make it fit

Insert your sleeve and sawcut it as flush as you can

Part III - Putting it Together[]

The options for what type or size tubes you use is wide open. You can fit this to blow either from the top or bottom--or both ways. What you see illustrated here has worked well for me. If these exact materials are not available to you feel free to experiment on your own to make changes accordingly as you see fit.<
