Resistance dropping after firing Claptons?

Can someone who's pretty good with making claptons and all that help me out?

So yesterday, my two spools of Ni80 came in and so I immediately went to my desk with my drill and tried making a fused clapton. Took about five attempts before I finally found that right groove and the wire actually looked half decent (note that I'm using 24 gauge Ni80 for the core and 38 gauge Ni80 being wrapped around it). Wrapping around a 3mm screwdriver, did about 6 wraps, dual coil, resistance came out to .08 which was a little frustrating for me since I finally was able to get a decent clapton out so I just pulled out one of the coils, rechecked the resistance for the single coil and came out to 0.16 which is a bit low for my comfort level but again, I went through too much headache for this coil go to waste lol. Since it was still reading a bit too low for my regulated device that I'm using, I put it on a mech and fired it up and wiggled it around to where it was glowing evenly and I rechecked the resistance but for some reason it READ AT .39

Is this normal for resistance to drop so significantly? (From .16 to .39 after dry firing and pulsing) I understand maybe a small jump after pulsing like from .22 to .27/.30 for example but I've never seen the resistance drop this drastically. Can anyone enlighten me as to what might've happened? Cause I honestly dont know. Gives me a great vape as a single coil but the drop just surprised me a bit.

It depends really. If it wasn't sitting under the post screw well enough it'll read incorrectly. Given that you're using a fused, I'm sure that was the case. It is a bit weird that you were getting .16 in the first place considering a pair of fused with 24 cores and 36 wraps n80 gives me .12 ohms. Odds are the wire had to settle in and the post screws needed to be properly tightened. Remember that a fused clapton is not round but flat, so you need to adjust your installation for that./

What Eekins said is correct, after first installing, ohms are always lower than what theyll be after adjusting, stretching, and squeezing into place to fire evenly. Also, since its Ni80, ohms are lower than kanthal anyway. Just expect for this to be common. I actually just finished a dual fused clapton 26G Ni80 wrapped with 40G Ni80, it started at .12 and settled at .2
 
Ah okay I think it might've been something with the connection like you guys said because I tried putting it on one of my IPV D2's and it read at .22 which was weird because like I mentioned in the post, after pulsing and adjusting, the ohm reader had it around .39. I think I'll just give it another and try to wind up a new pair before I call it quits lol but thanks for the inputs. Any suggestion with how many wraps and what drillbit to wrap around using 24 gauge and 38 gauge ni80 again? My target resistance is to be around .16 or above but I'm not too sure if I can do that with 24 gauge as my core lol

9-10 wraps on a 3mm id is a big set of coils that are going to be slow to respond unless you put them on a regulated mod but what is the lowest you can go on your reg mod?

if you used 26gn80 instead of 24gn80 you would need 6 wraps for the 0.16ohms.

if you went A1 kanthal instead of nichrome80 you would need less wraps again which can be handy for getting them to actually fit in the rda.
24g A1 is dual 7wraps 0.16ohms.
26g A1 is dual 5wraps 0.16ohms.

if you set the 'Setup' box on Steam calc to quad coil then you will be able to get a very close setup to a dual fused clapton.


Steam calc--> http://www.steam-engine.org/

this is 9wraps dual at 3mm id but unless you have a 150-200w reg mod it will be very slow and annoying on the heat up http://www.steam-engine.org/coil.asp?mat=n80&s=qp&r=0.16&hfnw=105&awg=26&id=3

Ah poop I knew I should've gotten the 26 gauge :(
I am planning on using the build on a regulated device but its the old Sigelei 100w which I believe that range for resistance is .15-3 ohms? Anyways, I might just try a regular clapton instead of a fused one. I'll check out steam engine as well. I've used the site before but not thoroughly to where I know what I'm actually reading lol

Or go single coil but with 5 or 6 wraps would work nice with the 24g fused at 3mm id.

If you look at the Steam calc link i posted where ive filled in the boxs for the build it should help you towards being able to do it yourself, once you get the hang of it you'll be flying :)

I've been using this build for a couple months now and it is fantastic. It's dual 24g ni80 core wires wrapped with 34g kanthal. These coils were wrapped on a 2mm screwdriver. It's on a mech mod though, and at about .08. OP, if you did 1 coil like this instead of the dual setup, your regulated mod would probably fire it.

Well hes using Ni80, with that size and loops with Ni80, it should fire up no problem with no ramp up time

The pic I posted above is on dual battery mech. It fires perfectly. I think 3mm ID is too big, and no more wraps than 5, maybe 6, is going to fit... even if you had something like a 26650 RDA and 9/10 wraps did fit, it would take forever to heat up correctly. Keep in mind that this is parallel wires wrapped with another wire. The coils are going to take a lot of space, even with a 2mm ID and 5 wraps.

yea I never did more than 6 wraps when I did regular parallel builds with kanthal because of the .... ramp up time especially if its dual. different story if it was on a regulated but the only time I'd go past 6 wraps if it was a single coil and it'd only be at 7/8 wraps so another wrap or so above 6. I figured the same would apply for a fused clapton when I was deciding the amount of wraps I'd do but as for the ID, I just went with the 3mm just because I always use it for my basic builds and wasnt really thinking about it lol

anyways, leaving the fused part out of this, anyone got any recommendations for wraps and ID for a regular clapton w/ the same Ni80 wires being used for it? would love it to be a dual coil setup but I can settle for a single if you can guarantee a good vape lol just put in another order for a spool of 26 gauge so until then, it will be standard claptons in all my attys

also, just want to make sure I understand the concept of a clapton coil, the wire being wrapped around the core wire doesnt do much in terms of heating correct? I watched twisted messes tutorial but the volume was low so I wasn't really listening to what he was saying lol I do remember hearing him say that the wire being wrapped around the core is just to help keep the vape cooler? anyways, I'm asking this so I know what to input on steam engine because if all the above is correct, I'd only have to input the specs for the core wire and just disregard the 38 gauge nichrome right? sorry, outside of my standard kanthal builds, I don't have much experience with builds involving nichrome and a drill since I just recently got both of them hehe i appreciate all the help thus far tho, love the ecf community because of all the responsiveness i always get when I post on here for help or random stuff

Do not put it as a quad build, it is still two coils, im just saying this because it will mess up calculations. It is a parallel build and theres an option for it. Im saying this because if you dont know, your resistance gets cut by the number of coils, so .4 single would be .2 dual and .1 quad and so on. Honestly, youll learn as you go and its the best way to do it, at least in my experience.
