RE: How do you dip yer wick?
Didn't this this deserved it's own thread, but I have several dipped wicks at this point. I understand DIY coils can last for months. How do know when retirement is at hand? Having burned so long the break? They no longer heat from the center out? Or just dissolve into dust?

RE: How do you dip yer wick?
I'm not sure. I have never used one long enough to figure it out. The longest I went was about 3 weeks of heavy vaping until I made something that I liked better. All still fine just goes into my coil graveyard. Some say they have been using the same coils for over six months and they looked fine to me. But I would think a leg will break or wrapping will break and you can't wick it.

Bibs, I have some coils I have used for 2-3 months. Usually about every 2 weeks I dry fire them and rinse them under running water - clean and almost as good as new... yes I can easily wrap or install another pair but why throw away perfectly good coils! Smile

RE: How do you dip yer wick?
Yup a simple coil seems to last an eternity , claptons and tisted coils not as long but still far longer than any coil unit . Just put a new coil in my tfv8 rba deck yesterday can't tell you how long it had been .

RE: How do you dip yer wick?
I've used them for so long any longer and it would have been Swiss cheeseĀ Sarcastic

All the metals I use contain iron. It seems to me that after extended use the alloy starts breaking down, migrating the lighter less dense metals. I cant say for sure thats the process but the pitting, rust, incurable oxidisation and heavy iron flavour are hard to explain otherwise..

RE: How do you dip yer wick?
Because I MTL my coils last a long time but I have to be careful about wicking as the wire I use is quite fine. I have a couple of coils at the moment that are over 6 months old[Image: tongue.gif]. I wick about every three weeks. Average time for my coils is about 10 weeks.

I'm a month in to my current gatorback build and it's fine so far. No intentions to change them anytime soon.

Now in case I missed it, what metal holds up best for longevity?

RE: How do you dip yer wick?
I normally go at least a month on my fused claptons. I do dry fire and rinse under cold water when I rewick, about every 3 days. Think the longest I've had a set of coils in was about 3 months and honestly they didn't look bad then just seemed to start gunking up faster for some reason. That's when I started going about a month or so and changing them out.

Keep Calm and Vape On!

RE: How do you dip yer wick?
Platinum - which would work as well as titanium in TC, it has about the same variation of resistivity with temperature as titanium. Given what a few inches of platinum wire costs.....

Any of the platinum group metals except osmium would probably be fine (Do NOT vape osmium wire unless you want to go blind).

Tungsten is pretty inert but has pretty high resistance.

Niobium is supposed to work well for vaping though it is a long way from cheap. It has one of the highest melting points of any metal at 2468C so your dry burning would have to go seriously nuts to burn it out - that's about a thousand Centigrade degrees more than the melting point of Kanthal. I'm guessing the wires advertising niobium content probably only have a small amount of the stuff in some sort of steel alloy. Niobium doesn't have a lot of chemistry which is what you want in a vaping wire. It does react with oxygen at 400C but mostly to form a passive oxide layer like aluminium does.

It is probably a top-up with any of the steel variants - which includes Kanthal though I'd expect slightly greater durability from Kanthal over SS. Something like 304/316/317 resist seawater corrosion well but there isn't a lot of salt in our vapes.

Here's a decent price on 18 gauge niobium wire.

This ad is probably very high purity niobium wire.
