The end result is a short outer tube with the coil and wicks exposed for dripping. Juice dripped between the side of the tube and the coil base will be absorbed by the wicks and transfered to the heating coils. Since these are relatively small amounts of juice, leaking is not an issue. The short tube provides a warm vapor.
1. Attach the G4 to a battery. If you’re overly cautious, use a dead or unloved battery. Rock the cartomizer back and forth on the battery base while gently pulling away from the battery. The tube will pull off the base, the tube may remain attached to the coil/base assembly, discard (or save if you’re a pack rat like me) the tube, you won’t be needing it.
2. Determine the desired length for the tube. The shorter the tube, the warmer the vapor. You may wish to use your drip tip as a guide. Using your razor blad or box cutters, carefully cut the tube to length. It may be easier to press on the tube with the blade then move the blade forcing the tube to turn. These tubes are fairly tough, it may take a couple passes and some practice to get a good cut.
3. If using tape or glue, wrap the coil base with the tape, or apply a bead of glue. Slide the base into the uncut end of your shortened outer tube. Let glue dry if necessary. Attach the drip tip, put a couple drops in there and start vaping.
