How to Coil a T4 BCC Clearomizer

The T4 is a pretty typical bottom coil clearomizer. I’ve actually had this one for quite a while, and it is probably one of my favorite overall BCCs. I particularly like it for the slim design, and the ability to use whatever drip tip you like. It is also compatible with most replacement coil heads from protanks and such.

Today I’m going to show you how to coil one up. This particular tutorial will focus on coiling one for a mechanical mod. Now most mechanical mods are going to look fairly lame with a long slim clearo attached, however there are some that it fits perfect. The KSD Novice and Smok ePipe come immediately to mind.

This is a pretty basic tutorial, and I am mostly just doing this to share the configuration I personally like to use with this device. There are lots of other ways to do it, but this way is very easy and has served me well.

What You’ll Need

  • T4 Clearomizer – get them here from Fasttech for $3 shipped.
  • 30 gauge kanthal – I strongly recommend using 30 for BCCs
  • Cotton Ball – Sterile or Organic
  • Nail clippers
  • 1/16 drill bit – I just picked up a pack of 10 titanium ones from Menards for $3
  • Pliers

Step 1: Wrapping the Coil

Ok very simple. We are going to do 6 wraps of 30 gauge kanthal around a 1/16 drill bit.

Wrap your coil. Once you are satisfied slide it off the drill bit. Hold a lighter over it until it glows orange, then carefully compress the coils together with a pliers until they are all uniform and sung against each other. Be careful not to press too hard or you could mangle the coil.

Once your coil is perfect, you are ready to apply it.

Normally I would tell you to slide it back on the T4, however in this case, the side channels on the T4 are slightly too narrow to fit a 1/16th drill bit. Instead you will need to find something a little more narrow – I used one of the tiny allen keys you get with certain atomizers from FT. You could also use a toothpick, piece of wire, or any other slim straight object that you can thread through the coil.

Once you have found it, thread the coil through it and lower it into the atomizer deck so that the coil is positioned in the center with both wires hanging down and out the bottom.

Next, bend one of the coil legs over the edge of the atty deck. Then slide the rubber gasket over the other leg and into the atty deck. Bend the other coil leg over the side of the rubber gasket and stick the pin in.

Your coil shouldn’t have changed position much during this process. If everything looks legit, clip your wires and screw the atty deck back into the base.

You should end up with something that looks like this:


Try to imagine it without the wick in there, because we haven’t gotten that far yet.

Step 2: Apply the Wick

Again, this is about as easy as it gets. That is primarily why I only took one shot for this entire tutorial.

First tear off a chunk of cotton ball. When you do this, you want to make sure you are going with the grain of the cotton – you should be able to easily pull off a small strand. You don’t need a lot.

Lightly roll the cotton in your fingertips – I usually roll one side to a fine point and leave the other side a little fat.

Thread the pointed side through the coil carefully until it gets too fat to go any further. Then gently roll the fat side a little more while pulling on the thin side and pull it through the coil a little further.

I usually like to have my wick be slightly loose inside the coil. You don’t want it too loose, but it should swell once you add liquid, so if it is slightly loose you should be good to go.

You will want to finish with cotton hanging off the channels on both sides of the deck – refer again to the picture above.

At this point, check your ohms.

Actually you could have done it before adding the wick, but with these I usually like to add the wick first because the coil can get jostled a little and the ohms can change, so I like to check them now.

If you did 6 wraps of 30 gauge kanthal on a 1/16th drill bit, you should come out to around 1.2 ohms. This is safe to run on a mechanical mod using a smaller battery like an 18350 or 14500. You could even go 1 or 2 wraps less, but I prefer to play it safe.

If your ohms check out, you should be all set. Pop the cap back on the coil and then add juice and screw the top cap back on.

The Bottom Line

This is what I personally think is the easiest way to coil up a BCC. There are other ways to do it, but this particular method should be about as straightforward as it gets. This type of atomizer is really best on a small mech mod or smaller VV/VW mod. If you’re going with the latter, I would suggest even adding 2 more wraps to up the ohms enough so that it will fire. You could probably even get this working pretty well on an Ego battery as long as you get the ohms high enough.

Sometimes simplicity is the way to go, and with BCCs in particular, they can have a tendency to shit on you at the worst possible times, so I like to keep the builds as simple as possible to keep any potential issues to a minimum.
