Do you save your coil builds?

[Alien Traveler]

Over time, the resistance will go up. When it gets to a value that you no longer want, it's time to build a new one.

Yes, the same for me. But I am in rta business only for two months and still did not have a bad coil. I've seen resistance change only on much thinner wires when I was rebuilding protank coils. Resistance change = coil had lost some of its metal (and some of lost metal may end up in my lungs). If resistance of a coil went up, it also means a coil may be ready to melt in its weak spot. I do not want to inhale melted metal, so for me increase in in resistance means I have to replace a coil ASAP.

Quite right, AT.

I generally build my PTs with 32, silica wick so I can dry burn a few times, with a cotton flavor wick that gets replaced each cleaning. They do tend to drift after a few burns.

My KFs I build with 30 and rayon. Bigger kanthal means it takes longer to drift, and some of those coils have been in for months. (I like the faster action of 30 over, say, 26 or 28. Heats and cools quicker than the thicker gauge, which suits my style.)

I don't save used coils. PT heads get rewicked regularly and rebuilt once every few months (I have dozens of them). For my KFs or RDAs, I rebuild when the mood strikes. They don't get used as often as my PT coils

Its interesting. How do you know your coil gone bad?

Usually it turns brown and/or the flavor changes.

Never save ones I've used. Takes 2 minutes to do a build so I just redo them. Only time I ever saved coils was when I built 3 or 4 sets of them, but they're unused. I use Unflavored in a lot of my setups, so I can have a couple last 2 months and it still be good. When I used flavored juices I maybe make it 2 weeks at most.

And what about dry burning?

Hey guys just recently got a Lemo2, wasn't happy with the coil that it came built with for some reason so built my first one to put in. I think it came out pretty good, I believe it came with 24g Kanthal and I did 11 wraps around 3.5mm came out to 0.9ohm. It takes a while to ramp up but seems to give a nicer vape to me than the stock one which was like 5 wraps around 2mm at 0.5 ohm.

Anyways, I tossed the original coil and now am wondering if I really had to or could have saved it. When you guys try new coil builds do you save your older builds? And being that it's really just resistance wire does a coil ever really need to be replaced or is it just for novelty/trying new builds?

For a while I autopsied used coils to get a feel for wire gauge, number of wraps etc.

Now I mostly rebuild old atomiser heads instead of buying new ones.

It's much easier than I thought it would be, rebuilding, watching all these videos on it seemed like everyone was making all these fancy builds tho lol. I'm happy to hear most people use simple builds cause it seemed much more complicated than it needs to be

Someone pointed me to a video clip showing how to lay the wick along a hairpin while winding the coil round it.

What I needed was lower resistance, that's either less turns or smaller diameter - I switched to winding round a sewing pin.

And what about dry burning?

Dry burning does nothing, honestly it looks like rust. I doubt it is but it stays brown after dry burning and cleaning.

Dry burning would clean a coil that had no wick through it, but when there's a wick, the heat congeals the juice into a kind of laquer, more heat just congeals a larger sphere of laquer around the coil that still seals out fresh juice from getting in.

Once i scraped and brushed a coil and some flakes came off

I never toss my coils if I decide to try something new. I pull the wick from my current build dry burn it then run it under water and ensure it is clean and save it incase my new build doesn't perform as well as expected.
I experiment with some very intricate and complex builds with twists, wrapping, and installations so if I come up with one that is kick-a## I don't toss it until I know I can replicate it flawlessly.
I have a number of RDA'S that have the same style building decks so I usually transplant builds between them to determine which ones it performs in better due to the difference in barrel sizes and airflow designs. I don't believe that any coil is used up or doesn't have future potential until a lead breaks or burns off. This is just how I roll.

ok cool this is really more what I was thinking at first, like you said with intricate and complex builds cause they look like they can take quite some time to build and I kinda figured if it ain't dead why bury it? lol. Good to hear I'm not alone in my hoarding everything that may one day have a purpose

The wick stock I bought is too fragile to re-use - every once in a while a new wick disintegrates while I'm winding it!

 

[Belhade]

I've got a few dozen old coils, going back to Protank 2 builds from years ago. I come from a long line of hoarders in my family. One day I'm going to make a mini-docu of emptying out my vaping kit.

 

[Foggyroomz]

My thought is you've taken the time to build it rewick and enjoy it again and again the coil doesn't really go bad if you take care of it properly but the wick can so before rewicking clean the coils and reuse them. I hate to waste things especially if they work good.

 

[rhelton]

I keep some of them in a empty chew can they have come in handy a couple times ive been out of kanthal.

 

[VHRB2014]

If it was a good set up, and I may want to go back to it at some time, or use it in a different atty. Only good coils, crap coils go in the ashtray/trash. I have a little box-o coils in my kit, Iv even reused some of them and its so nice to just pick out a set and plug them in.

 

[KenDogg1024]

now that i've built a few coils I can say I don't blame anyone who throws away their simple micro/macro coils cause theyre really not that bad to build at all. For those of you who have saved and reused after a while isn't it a royal pain in the ... to get the tiny leads back under the screws unless there's a lead hole like on the Lemo?
