Glad i found this port, been looking for a coiling tool for a while but everytime i find one, it's out of stock.
I wrap under tension, but don't use a jig. I have a clamp/vise I use to pin one end of the wire to the edge of my desk, then wrap on a drill bit held in a vise grip, winding it toward me. Cheap, easy, works good.
MacTech: Through this thread, I found your blog and drank deeply from the cup of your knowledge. Many thanks!
Also I don't get why so many people are still torching. It's been written about everywhere here that this degrades the wire since super_X started tension winding. Annealing the wire just starts the oxidation process. Regardless we end up pulsing anyway. Why not do it with the virgin wire and get it right the first time?
I do it to burn off whatever contaminants from manufacturing are present on the wire so I am not inhaling whatever that is nor getting it into my juice. Whatever it is, it's nasty.
So many are caught up in the technical arrangements of how to put something together, but forget to think if it's healthy or not. Maybe it doesnt make sense from a technical point of view, but it makes sense from a health perspective.
And you know this how?
One of the main reasons I'm here. Always concerned about my own neck nasca, for sure. But I also write and post though to help others with their technical concerns. And technically correct would have to include this issue, being…pulsing should evaporate off any indicental contaminants as effectively as annealing wire without adding any combustible residuals to the wire (carbonized hydrocarbons) while you're at it.
It is that carbonization which would interfere with optimal electrically induced surface bonding that's the technical concern I was talking about. To gain electrical efficiency that inhibits shorts, dry burns and a bad vape (I won't say bad health unless one is inclined to keep avoiding healthier alternatives).
But burning the wire does nothing much but damage it and introduce…well, contaminants. At least that would be my informed take having often spoken with the manufacturer Sandvik and distributors frequently. I always recommend due diligence regarding products that we use. Perhaps that should apply to information sources. Myself included.
I can live with just the alumina oxide layer. I wouldn't ask anyone to do anything I wouldn't do myself. The method I introduced doesn't forego annealing anyway. It's just done more directly and in a way benign and beneficial to outcome of the wind (tension winding).
So I'll do a mythbusters here to add that Temco Industrial Power, the most well known supplier to vaping, as well as the manufacturer do not add or use any lubricants or other additives to the raw surface of Kanthal A.
Kinda makes you wonder nasca why all these videos proselytizing on the benefits of burning the crap out of resistance wire? When a simple phone call from any of them would answer the question that it's not necessary. Furthermore, that they don't report how pre-oxidation may compromise the wire.
(I am amused at times nasca that some video makers acknowledge that it's not necessary, but that they do it regardless.)
Just sayin'.
Good luck nasca. And thanks for your thoughts.
Whatever your rationalization is...
I'm pretty much fed up with buying vape ready atomizers. Kanger and Aspire are both creating heads with faulty silver solder connections to non-resistive legs. 8 hours of vaping and a coil is toast. The solder joint breaks down and finally reads open. I just sent an email to Kanger outlining the problem. I'm sure they are aware if they have any vapers in house. Maybe they want us to replace a coil every day. It's more revenue for them.
Not me. I have a Genesis RSST and just ordered a Kayfun 3.1. I have 100 or so Kanger used heads in zip locks that I can micro coil. I have a spool of 28ga and a spool of 32ga Kanthal and the coil winder. There are several vendors who sell post insulator grommets in bags up to 100. I can replace them every time I recoil to prevent burning.

You should burn it off for many reasons. Even if they don't use lubricants on their Kanthal a-1, you're subjecting yourself to whatever is used in their factory. During transportation, spooling, sitting in a warehouse, etc. You dry burn it for the same reason you wipe off the top of a Coke can. Sure, Coca-Cola doesn't contaminate their cans at the factory, but I've heard of supplyers warn ALWAYS to wipe off the top of the Coke Can. You know how many times I've went to a store and saw a sticky can of soda? That wasn't done at the factory, that was done after it was canned and shipped. I've also heard stories of refrigerant leaks in the delivery trucks, people taking breaks on a pallet of coke and "passing gas" and just laughing about it.... It altered my thoughts about sanitizing just a bit before use.
As far as torching it goes.... Torching reduces the tension of the wire. It makes it less springy. IT makes it easier to coil. Also, it makes it not bend as much when it does get hot. Take a straight piece of kanthal, and torch it.. you will see it bend slightly. let it cool down, straighten it, then try the same test.... it won't move. I did this test again just now. I used 24 gauge kanthal. a higher gauge might move due to gravity, but the initial heat does warp the coils a bit. When I wrap a coil, I like to torch it first... if it moves while it's in the atomizer, it might cause uneven heating, sagging, or who knows what inside of your atomizer.
