rebuilt coils problem

[Chris_UK]

Hi all

Recently tried my hand at rebuilding the kanger occ coils for my subtank mini, I've done about five now and keep running in to the same problem:

The coils continue to hiss for about 2 seconds after I release the fire button and I get a burnt taste

6 spaced wraps 26 gauge kanthal, 3mm ID (approx 1 ohm), wicked with KGD cotton (just enough for slight resistance when pulling through coil)

Any ideas?

Hello @Chris_UK. Welcome to ECF. I'm from the UK aswell, Birmingham.

Sounds like your coils are taking longer to cool down and drying your wick out, also maybe singing it possibly giving you the burnt taste.

Don't ask me, Chris.

I gave up on them months ago and just got the RBA (mini) instead.

Most of mine (same as yours by the sounds of it) failed. I tried 2.5mm and 3.0mm diameter. 5 different types of Kanthal, 3 types of cotton wool and rayon.

I just ordered a lorry load of packs from Fasttech (for the Nanos), I can afford 10p a day.

So, I can do a Kayfun or Orchid or quad coil dripper, but these... no chance.

Think I'll have to try out the RBA and see how I get on with that, thought rebuilding the stock coils looked easier but it seems that I was wrong

I'm sure you'll find the rba deck a lot better to buildon, plus you can play around with twisted wires and even claptons. There is a bit of a knack to wicking it though but not to impossible.

I had the exact same issues trying to rebuild these. I tried more cotton, less cotton, poking the ends of the wick with a needle.... Nothing worked.

However when a made one from nickel for my dna40 it worked like a charm. So unless you have a temp control device I would just say buy the standard coil heads. That's what I ended up doing.

I hope someone comes along with a remedy for us

Update for anyone interested-

So I gave up on rebuilding the stock occ coils and gave the RBA a try, I used rip trippers video as a guide for my first attempt and it worked very well indeed, IMO as good if not better than the stock coils. Built a second in my other subtank and results were just as good.

It seems a lot of people struggle with wicking the RBA but by keeping the juice channels clear and not packing (compressing) the cotton I have had no issues at all, and it's so much easier than trying to rebuild a stock coil

Dont know how to post a link on here but search on YouTube for 'subtank mini RBA' and you can find rip trippers guide easily. If you use higher vg juice (70+) he has a video about the pancake method which should help ( I use 50:50 so the standard wicking method is fine for me)

Hope somebody finds this helpful
