Cool. I've been considering that myself. Which is working better? What size of wick are you using? I'm too cheap to pay $5 to ship $2 worth of cotton. I'm hoping to find something locally.

I just went to walmart and got 100% cotton Worsted weight yarn it was like $3 and 100% cotton embroidery floss is .30 cents
The yarn gives great vapor and taste but will burn up if not kept wet but at the cost I don't mind making a new wick and coil every couple of days.

I'm using resistance wire. Non resistance wire is for long coil leads where you don't want the extra resistance of the legs that don't do anything but conduct electricity. It's also to prevent heating of the leads to the coil where they might burn something.

The leads are so short on the Vivi that there's no point in using non-resistance wire. It might shave off 0.001ohm or something. I'm using 34ga. Kanthal-A wire. 32-36 will also work, just adjust the number of wraps. More wraps on thicker wire and fewer on thinner wire. Six wraps of 34ga. gave me 3.7ohms. I don't care because I use a VV, but the next time I do one, I'll use 5 wraps which should get me close to 3ohms or slightly above that. If I had it to do over, I'd probably use 32 ga., but 34 works fine and it's all I could find in Kanthal-A.

The resistance is rated in ohms/foot of wire. Unless you want to do a lot of complicated math, don't worry about it. Just use 4-6 wraps and see how it turns out. If you're way off, do it again with some adjustments. It's so fast and easy, it's not worth trying to predict in advance.

There is a good seller on Ebay for Kanthal-A wire. A 75' spool costs about $7-8 shipped and got to me in 4 days.

I suggest thick wick on the Vivi. A short fat wick seems to work the best. At least bundle your wick if you're using thinner strands. With normal CE2 wick, you'll probably want 4 strands.

Thanks Sailorman, you're the best :toast:

Get Kanthal D if you have to. Nichrome is a lower temp wire and won't last as long. Silver is the non resistant wire. I'm surprised if COV has any resistive wire in stock. If they do, I don't know what it is, nichrome or kanthal. They would be good for wick though.

You're right, COV don't have resistance wire, sold out too. I'll look again for Kanthal A, or I just use all my heads then rewick after all of them gone. :D

Good find on the Kanthal. Eh... I'd skip the SS mesh for now. You have to oxidize it and I know it works in a Genesis, but that's built quite a bit differently and there's a lot more room to work. If you're good at braiding, you can use cotton gauze, but it sounds far too tedious to me. Cotton candle wick is supposed to work real good. Silica is the most common, but some of it is really thin. I got some 1mm dia. and it's way too thin. I'd have to quadruple it. 2mm is good for a single strand short wick. The slots in the head for the wick to pass through are 2mm wide.

Where did you find Omega XC-116 wick? What is it? Do you have any info.? I need more wick myself.

Hi Sailorman,
I think I pass cotton gauze :laugh:
This is the link for Omega XC-116: Nextel Braided Ceramic Very High Temperature Sleeving
$15 for 10 ft, I don't know about shipping but from I heard it's flat rate $8 no matter how much you buy.
I think it silica wick :confused: You can find all the information there.
Do you think cotton candle wick safe?
I want to buy that Omega wick, but I need to hear from the expert (Sailorman :toast:).
Thanks

how do you rewick one ? Is there a tutorial somewhere for that? I don't want to mess with any wire but I have enough cotton yarn to last three years in my closet because I crochet with it.

Since the existing coil is wrapped pretty tightly around the wick, it might be really tough to get the old wick out and push a new one in without damaging, distorting the coil. But, I've never tried.

+1 on that video ^^^^^.

I'm not so sure about that Omega X116 Sleeve. I think they use that kind of sleeve for atomizers, but I'm not sure how it would work for a wick, since it's so thin walled and hollow. It's probably what the tube surrounding the coil is made of though.

If I had a little piece of it, it would be worth an experiment but unless someone has actually used it with good results, I think I'd stick with solid rope

Not tough, impossible. The wire is wound so tightly around the wick that even if you managed to pull it out, you'd never get another one in there. Not in a million years.

I'm no expert, that's for sure but cotton candle wick is safe unless it's treated with some chemical or something. You can boil it, like the video shows, if you're concerned about something on it. You just can't do a dry burn with a cotton wick. It's quicker to re-wick these heads than it is to clean and dry burn them anyway.
