Should only be doing good things. Resistance of the legs reduced (so they shouldn't heat up), only the coil will be heating. Overall resistance might go down a bit, but that just means that resistance of the head is closer to resistance of just the coil itself.
I'll have to try it when I get my new novas
I'm electricity/electronics 'challenged' so I was just going on the assumptions that it reduced the Ω of the legs, so the overall Ω of the coil was more directly related to the the # of coil wraps and it would reduced the heat 'in the legs'. Without the twisted legs, even though they're short, the length of the legs adds to the overall resistance of the coil (not just the # of coil wraps).
Thanks to MISTer E for providing the actual measurements!
Does that work good BJ43? No matter how much twisting of the legs I do they still heat up. Would love a solution aside from using NR wire. I've all but given up on my novas for the time being, may revisit them if that method works good though.
I have only done it with 28g which is very thick and double wrapping it makes a very thick wad of wire. The first that I did this way is still going strong after 10 days of vaping with no burnt taste. On the original Vivi novas the silica sleeve under the coil does this same function. Keeps the legs wet and cooler.

Hmm now that I think about it, it's probably because I'm using 36g. Even doubled up that's still super thin. Which would explain why it's still getting red hot...
Been using a SS mesh wick in my Vivi Nova 2.5. Huge difference. Still some wicking issues... still tilting and twirling...lol. But much better taste and vapor. Actually gave myself a nic buzz... 1st time ever from vaping. Just make sure you have a PV that can handle a 1.5 ohm load. Using 325 SS mesh and 32g NiChrome. My coils always seem to come out at 1.5/1.6 ohms.
Using 32 awg with a 4/5 wrap on 400 ss mesh gives me a 2.3-2.4 ohm load which is perfect for my VV mods
This is my first attemp at a SS 400 Mesh wick to try to duplicate this tutorial with my Phoenix RA. Reinventing the Phoenix Rebuildable Atomizer « pinoyvaper
What is a common size for the rolled up portion. I made my first one last night with a 1.5"x1.5" square piece. Obviously it is 1.5" long but should it be a greater length for the rolled part to get wicking to the coil?
The tightest I could roll it left a .044" hole in the center. Is that close to normal?

I changed mine by using a 16ga wire lead to the kanthal. I used a hammer to flatten the leads to easily fit into the grommet/plug. Result is no more burnt tatse, and more wraps around the wick. You may want to give it a try....
Hammer you say? Hmm.
Can you provide more details, this is interesting.
What type of 16ga wire do you use?
How do you attach the 16 ga wire to the Kanthal coil?
I assume you hammer first?
That's a great idea, I'll try that when I double twist each leg. Good thing I always keep my trusty hammer and anvil near by.
I twist the coil ends. It lowers the resistance of the 'legs' to minimize burning the gasket.
Thank you again for the advice, works like a charm! I even made one improvement:
Before rolling the mesh, I folded over the sides by about 2mm. This way the coil looks kind of like a dumbbell. Prevents fraying of the sides, and seems to keep more juice inside the SS part of the wick.
Hmm, new strange development. The new coil was working beautifully -- great flavor, tons of vapor. After sitting on my headboard overnight, and after about half a tank of liquid (50/50 PG/VG, if that helps), the vapor production dropped tremendously, flavor went to that of a carto, and the throathit went *up*. Anyone know what it could be?
Your wick has too much liquid and is boiling instead of vaporizing
16ga copper wire - had it laying around.
Soldered them together, but you can probably crimp them if you have a clip small enough to keep em separated.
Nope. Had to hammer last because I didn't know how long I needed them to be. Just handled with care...

Hmmm, I never thought about copper wire. I guess it wouldn't be in contact with the juice so it should theoretically be fine.
Oh. Thank you! Didn't think about that possibility. A bit stumped on how to reduce wicking
I got a short SS wick with two cotton overwicks. Will try to replace the cotton ones with a single silica one.Thanks,
