I've been wrapping a 5/4 with 28awg and I always end up with 1.1Ω. I'm hoping that with the ribbon's increased surface area that a 4/3 of the 0.24 will provide more contact with the wick and still give me about a 1.0Ω coil. We'll see.
here's the spec on the on
Kanthal D Ribbon resistance heating flat wire 0.6*0.1mm / 0.024*0.004"
select your lenght: 5 Meter / 10 Meter
- this Kanthal D is the best heating wire for rebuildable atomizer
- it will be shipped on its own spool with 55mm / 2.17" diameter
Product information:
Manufacturer: Kanthal Sweden
max continuous operating temperature: 1300°C ..... 2372°F
resistance at 20°C: 29.3 Ohm/m ..... 8.93 Ohm/ft
select length: 5 Meter / 10 Meter ..... 16.4 feet / 33 feet
width and thickness: 0.6*0.1mm / 0.024*0.004"
alloying elements: Cr 22%, Al 4.8%, Fe remains
I wonder why the thinner one has higher resistance (or am I missing something)?
LOL, I actually ordered an inline volt meter just so I can compare under load voltage drops. "Curious minds" want to know...

I excitedly brought mine out to play, and it refused to work anymore on any of my mods.But it was fun the 10 times I did use it a year ago lol.
Thinner wire always has higher resistance because there's less material for the electrons to flow through. 28awg is thicker than 30awg and therefor lower resistance.

I clicked on that link and it took me to eBay. Unless I DID something worng here's the details I got by deviding ohms/ft by 12 in.

Now that I look at it your absolutely CORRECT! I looked at the 16.4 ft from the length... That wire comes in at 0.464Ω/in which almost exactly like 28awg (0.439Ω/in)
I'm no electronic expert. But I do have some experience. There are many. Challenges
I think when using the poldiac the real resistance point is now the ss in the atomizer and tube and spring. I hate springs I plan on going back to brass positive post But then the negative is ss. I think no way around that unless jim makes a base from a more conductive material. I hope I will be able to buy brass top and bottom cap. With brass tube. Keep the ss pants.
The under load. Test. Try this. Battery touching positive post on atomizer use 12 gauge wire to negitive. Read voltage drop. This takes mod out of equation. Then with same battery install it in the poldiac. Take a reading.
If you look at rw video he just did on a tube mod. He removed the spring in it and improved it. That really showed what the spring did. But still not sure what the mod does.
Hey Rick can you do what I just said.

Sounds like this should work absolutely perfectly then. I usually vape at about 5/4 28. I'll try this at about the same.
That makes sense. I metered the Poldiac by itself and there was no drop at the posts. But then again I'm running double bottom silver coated springs so it's pretty solid.
Tried it with my crappy mm that only shows voltage to two decimal places. Battery alone read 4.03. With Poldiac it read 4.03 and 4.02, fluctuating between both numbers so I assume about 4.025. This is with ss post. I didn't measure under load because, as Tony said, it's irrelevant due to the drop caused by the battery sag. Can anyone really feel a difference of 0.005 volt?
How did you arrange the springs. Have a photo
Tony
just twisted 1 inside the other and then installed as normal

Ordered my Poldiac BTO yesterday and its in the post today, should be here by Friday, now thats a great turnaround , Excited i am to say the least !
