I'm going to try the cotton. Are you rolling the coil in a nice tight roll around a nail or something? I found I'm getting a better vape by rolling it by hand and not very tight space a bit apart. Making a nice tight coil seems like a better approach if I'm going to be putting cotton into it every day. Then I can dry burn the coil between cotton swaps. Correct?as long as it's 100% cotton it will be fine. You may want to boil it first though. If you're using silica and your wick is getting all gunked up in a day or so you can dry burn it and rinse it off. If you switch to cotton then you could just pull out or burn off the old wick and thread a new one. I've had the same coil in 1 of my daily drivers for over a month now. Every few days it gets a fresh piece of cotton and it's good as new.
Hand picked cotton eh? I saw some in the fields today and thought about nabbing some. I think i got a pretty good coil now. Measures a little high, around 2.2 - I have cotton in there now. I like it. Hopefully I'll just be changing out the cotton daily. Making a new coil with that silica everyday is getting old. Next coil will be a little lower ohm.
Sounds interesting however realestate on this deck is so small I have enough of a challenge getting one decent coil on there. Next rebuildable will have more space. This is my first. It was really inexpensive. I think I paid $6.95 -If you're using a higher gauge wire like 30 or above you might want to experiment with a duel wire or parallel wire set up. Just fold a piece of wire at the middle and wrap the two wires side be side as if you were wrapping one wire. I use 32 gauge kanthal and that's how I do all my coils anymore.
If you have a 1.5mm or 1/16 inch allen key, try wrapping your coil on that. Wrap as close (touching) as you can but a tiny gap here and there doesn't matter. If you happen to have 32, try about 8 wraps (16 coils) and adjust from there.
My coils usually last about a month if I'm running only light juices through them, 2-3 weeks if I'm using heavy juices, they can keep going at this point but the flavor is off. ...............
Kanthal is cheap, $5-10 for 100 ft, I'd rather just make a new set of coils that will perform better than try and drag an old pair along.I use a couple drops of hydrogen peroxide to freshen up my coils every once in a while. It turns to water under heat so I think it's safe enough to use. It makes a great mouth wash as well, mixed half and half with water, and helps with my vapors tongue that I seem to insist on developing every once in a while. For silica users, it helps freshen it up as well, but I think taking a torch to the silica might be the way to go there unless you have grommets or orings to worry about.
