I've got a tank that uses these heads that I got from TECC in the UK.
I suspect that they're a fairly common thing that's been rebranded.
Are they rebuildable?

Those look an awful lot like one of the heads I got with a Totally Wicked tank; bottom dual coil (BDC), right? I know TW sells TECC stuff, so that's a clue.

Anyway, I had limited success by looking at Rip Trippers' video on rebuilding Aspire BDC heads. They're really a pain because they have this thin strip of cotton where the two pieces press together; it was not fun getting it back in. Also it takes a lot of patience to set up those dual coils.

Anyway, to get mine apart, I had to use two pairs of pliers - one on base, and one on the chimney. Wiggle the chimney one and it should come loose.

Don't take the bottom pin out if you want to keep the stock coils alive; I mangled the coils by dismantling too much. You can take the chimney apart to expose the coils without ruining anything.

I found that video - they're not quite the same are they?

I was going to make it a single coil so not too bothered about mangling the existing coils.

Looks like I'll have to buy another pair of pliers. The expense is never ending.

I've never owned any aspire coils, but my totally wicked ones look just like that, and the Rip Trippers video was the only thing that helped me get to rebuilding mine.

So I won't say they're exactly alike, but I have a sneaking suspicion mine came in a rebranded aspire tank; for what it's worth :D

I hear you on the nickel and dimes! First it's just tanks, then Kanthal and rayon, then multimeters for me... The peripheral damage just keeps coming!

I imagine you could just use pliers on the bottom, and wiggle the chimney by hand. Maybe. At least if I just had 1 pair, that'd be what I try first.

I'd already tried wiggling the chimney by hand and it wouldn't move - just couldn't get a good grip on it.
There's no rush on it - I've got some more in the post.

I know the idea of making your own coils and doing DIY is supposed to save money, but it often doesn't seem that way.
Coil built at local B&M - $5
5 pack of coil heads - $12
250ft Kanthal online - $18
Lifetime supply whatever wick - $10

The math supports DIY is better

Just to let people know that I finally got round to pulling one of these apart and replaced the double coil with a single 1.8 ohms coil.
And I did it with only one pair of pliers.

Remove the metal insert and the rubber bung out of the bottom.
Then pull the remains of the old coils out using needle nosed pliers or tweezers.
Here comes the ingenious bit - hold the top part with your pliers and insert the bottom part into the hinge end of a door.
Gently close the door till it grips the atomizer between the door and the door jamb - don't press too hard on the door, just enough to grip but not hard enough to bend.
Pull on the pliers to pull the chimney away from the rest of it.
Then recoil as normal for a single coil.

It actually seems to perform better as a single coil, though I've yet to see how long it lasts.
