Really need help coiling SS fused clapton to reach about .25ohms.

[poolman]

The equipment first I am using geekvape SS fused clapton wire 24ga*2+ 32ga. Working with the reload rta. I have tried many different builds 2.5, 3, 3.5, 4 mm ranging from 5 to 7 wraps apparently, I have not found the right combination. I keep getting readings about.08 that I can adjust it to .1 or .11 start to work the coils. Then I let them cool and get my cotton ready and it jumps back down to .08. Finding .25ohms would be desired but at this point any thing above .1 would work. I have checked the connections and checked if the coil was touching the deck; both look good. I have tried steam engine but don't know how to input fused claptons. PLEASE HELP. This is really frustrating!

People using geekvape coils often have this problem. The wrap is too big and on the reload, SS 24g is a bit big and a bit low to hit 0.25, especially with a huge wrap.

The clapton wrap doesn't affect the resistance other than the increase in ID so you input 0.2mm over your jig ID to fix that.
They used too big of a wrap (32g is massive for a clapton), the cores are huge for such a wrap making that a ridiculously inefficient build and the quality of the wire is poor at best.
If it were kanthal you'd have a much better chance of getting it to work but fused 24g SS in a small atty like the reload with a huge wrap is a bad combo. I usually use a 2.5mm ID to easily clear the chimney and I'm using 0.4mm thick core with a 40g (0.08mm) wrap. You're using a 0.51mm core with a 32g (0.2mm) wrap and that wrap is adding an additional 0.2mm to you're ID which makes it much worse.

I'll gladly make you something that will actually work if you'd like. If not, buy better pre-made stuff but be careful because they're all taking as many short cuts as they can.

Are you using a regulated or an unregulated device to fire the coils?

 

[whiteowl84]

I assumed regulated because they said over 0.1 would work.
I'm tired of explaining why the ohm load doesn't matter on regulated mods (as long as it fires it) so I didn't.
If it were a tube 2x 24g SS would be great with a 38g or 40g wrap.

 

[poolman]

yes regulated RX200.

Try SS316L 28*2 awg as core and SS16L 40 awg around. Then you should get 0.25 ohm with 3mm at 8 wraps with dual coils. Should vape between 70-140watt.

Try out the app vape tool pro for Android?

yes regulated RX200.

Then the coil resistance is not really important, why are you so intent on achieving 0.25 ohms?
The resistance of SS will increase temporarily with temperature hence why it's used with TC. Any other shifting of resistance will usually be down to poor post connectivity.

The resistance on the wire you are using is so low you really need to make some huge coils to get the resistance up. Steam Engine says 13 wraps on 3.0mm id to get .15ohms with dual coils.

I have a dual coil Griffin tank, so I've made 2 .50 ohm SS Claptons and end up with .25 ohms. I use 3 28 gauge wires wound as a Clapton, 8 turns on 2.5 mm. Lots of combinations using thinner wires to get a .25 ohm coil but I'm sure it is possible. I have a Daedalus to wind coils and when I first started I used 32 gauge for the outer wrap but went lower since.
At the same time I have a tank taking dual coil Claptons for a total of .40 ohms, can't find a .80 ohm coil for that so I had to make one.

Ah... Miss from me. You bought a pre-made Clapton wire. That one is more made for like low build for maybe more mech or at least around 0.1 ohm dual or 0.2 ohm in single coil.

Anyway you should try and make your own, ain't that hard, start with single core Clapton and when that works you can easy start to make fused Clapton.

My 2nd attempt on building my own Clapton (28x2/35 SS316L).
