Dripping with ni200

[n30nex]

I'm trying to do some TC builds on my Troll, but I feel like I am going about this wrong.

I'm using 26g, and I have to coming out to a scary low 0.062, the wire is tight in the posts and I used a thicker ID then I normally would. It's hitting nicely but I see some hot sections, I could not space it effectively without going even lower ! Tips, tricks ? It's nice and cool @ 50J and 420 - 500f

You'll have to move up in wire gauge and then make sure it doesn't touch at all. That's the secret lol.

I do not own a TC device, yet. From what I understand do as the above post and leave visible spaces between each wrap. As for the wire gauge and resistance it seems the build isn't going to work out well considering the wire used and target resistance. Either decrease the target resistance to allow for more space on the deck, or choose a higher resistance wire for the same target resistance to allow for more space.

Ideally you should go up in wire resistance.

Here's another vote for spaced coils and going up in wire resistance. I personally like 28ga or 29ga, 12 to 14 wraps, spaced. G'luck

Spaced coils, ( the reasoning is TC works better and more reliably)
also try to go 3mm ID will help lessen the wraps.
With my vapor shark i've found hitting .10-.11 is the sweet spot

I just threw together this baby:

It is a single coil with two strands of 32 g ni 200 wire twisted, 12 wraps with an ID of 3 mm. I'm firing around 330f at 20w. The flavor is insane and the cloud production is like nothing I've seen at such low wattage.
I am noticing after a few refills that the coil is burning more where the wraps are closer together so I'll need to space a little better next time but dang this is a mighty fine hitting build. It sucks juice quickly!
@n30nex I agree with the responses so far in that thinner higher g wire will get your ohm rating up and spacing them a little more will help a ton. I haven't worked with 26 ni wire yet, though I'd like to, but it probably makes spacing slightly more difficult than some higher g wire since it is less springy. With 32g I can wrap the coil without worrying about spacing and compress it. It automatically springs back with perfectly spaced wraps. Also, this is the first time I kept the coil compressed as I affixed it to the atty and it really helped! Good luck with your future builds. That coil you wrapped is pretty though.

Compared to kanthal or even ti, ni has almost no resistance. 28 awg ni is about the largest wire size you can use and still end up with builds that are reasonably sized for the given resistance.
I have a mutation x v4 and 28 awg is the largest ni200 wire I can use without serious size issues. If you are using ni200 TC is basically a given since I don't know any devices offhand besides TC mods that will fire builds between 0.05 and 0.1 ohm.
Even if you have a device that will fire at a minimum of 0.05 ohm, you will want to build to 0.07 to give yourself some buffer against resistance fluctuation causing your device to fail to fire when it goes into its flavor of resistance protection.

The attached photo is a single 0.1 ohm 28 awg ni200 coil with a 3mm inner diameter mounted on a mutation x v4. It was part of a pair that settled down to too low of a resistance for my evic to fire after about 8 ml of juice. I didn't have enough time to wind a new pair before work so I stuck the AFC plug into the unused side.

I keep posting this as a way to get nice even spaced coils... I really should probably stop, but here is a thought.

This should work really well for nickel builds. Have you mounted the coils still threaded around the bolt? Then I assume it's easy to screw it out and the coil keeps form? I've seen this idea before just never got around to trying. I appreciate the post!

 

[LilWhiteClouder]

@EverPresentNoob it was probably your idea in a post I had previously read I am glad you have kept posting the idea, it's a good one.

I've used this method since I started using nickel. With tempered ni200 the coil will often space out a tiny bit more when unscrewing the screw, but I think that's due to me pulling a bit on the screw. At times I've had some problems with the coil getting stuck on the screw, but that's when I've put some force into positioning the coil and thus tightened it around the screw.

when this happens just gently squeeze on the coil on the screw and hold the coil as you unscrew it. sometimes you have to slightly wiggle the whole screw in a circle to slightly stretch out the coil to get it to let go of the coil. not twisting the screw, but moving it in a small circle inside the coil... This coupled with holding the coil gently with your fingertips while unscrewing it normally allows it to come right out. Occasionally I get one that is just a total bugger to get off the screw and I just destroy it and make a new one. Normally I use my needle nose pliers to bend small dog leggs into the legs fo the coil so I dont have to fight to position them.

Also I dont use tempered, and mine will open up a little bit, but not much.
