How To Build Micro Coils For Use In Your Electronic Cigarette

If you own an electronic cigarette that uses micro coils, then you can save money and find it personally satisfying to construct your own coils. The process isn't difficult, and it only takes a few basic tools. Below is what you need and a step-by-step procedure to building your own micro coils:

Building micro coils for your electronic cigarette - tools and materials needed

  • 28-gauge electronic cigarette resistance wire - Resistance wire is sold for a variety of applications, but it is best to purchase resistance wire designed for use in electronic cigarettes. The specific alloy composition for electronic cigarette resistance wire will provide better heating characteristics and a more-satisfying usage experience as a result.
  • Jeweler's pliers - Pliers designed for use in jewelry making are ideal for creating micro coils due to their small size and ease-of-use when handling thin gauge wire. If jeweler's pliers aren't readily available, you can also find satisfactory results by using standard needle nose pliers or even a pair of tweezers.
  • Size 1 aluminum knitting needle - A size 1 knitting needle is 2.25 mm in diameter, and this is an ideal match to the coil diameter you need. If you own a 1/16-inch drill bit, you can use this instead if you can't locate a knitting needle.
  • Transparent tape
  • Small butane torch
  • Triple-refined butane fuel
  • Wire cutters
  • Well-lighted workbench

Building micro coils for your electronic cigarette - step-by-step procedure

1. Prepare wire for coiling—Resistance wire possesses some degree of "memory" and won't respond to coiling until it is heated. Begin by uncoiling approximately eight-to-twelve inches of 28-gauge electronic cigarette resistance wire and cut it with a pair of sharp wire cutters. Straighten the wire between your fingers and firmly hold one end of the wire with your pliers.

Ignite the torch and adjust it to a blue flame setting, then pass it slowly along the length of the wire until it begins to glow bright orange. Be sure that every part of the wire glows brightly, but be careful not to accidentally pull the wire apart while it is hot. Once you have heated all of the wire, then set it aside to cool down.

2. Fasten the wire to the knitting needle—Measure 3 inches from the pointed end of the knitting needle and attach the end of the wire to a size 1 knitting needle with a short piece of transparent tape. Be sure the wire won't move, so attach another strip of tape, if necessary.

3. Coil the wire around the knitting needle—Grasp the resistance wire between your thumbnail and forefinger and begin wrapping it slowly around the knitting needle. Pull the wire tightly while coiling it, and keep each coil as close to one another as possible without touching. Keeping wrapping the wire around the coil until you have made ten full wraps.

Once you have made the coils, push them down the knitting needle until they are adjacent to one another. Be careful not to push the coils too far to prevent them from overlapping.

4. Tighten the coil—Remove the tape from the knitting needle and pull the coil away from the needle. Next, slip the coil between the jaws of the pliers, and lightly squeeze so the individual coils are compressed together. While continuing to hold the coil in position, ignite the torch and adjust it to a blue flame setting. Pass the torch flame through the individual coils until they fully heat up to a bright orange color; keep the flame focused on the coils so they continue to glow for five to ten seconds, then remove the flame and allow the coil to cool.

5. Cut the coil to length—Once the coil has been heated a second time and cooled, use the pliers to adjust the two end lead wires so they are parallel to one another. Snip the ends of the wires to cut the coil to the proper size to fit your electronic cigarette.
