You’re using the ‘coil wrapping’ page. I always use the ‘wire wizard’ page. I’ll input the # of wraps I want, etc. and then look what the Ω’s look like, and then change what I want.
I usually build to fill the span between the screws. I don’t want long ass coil legs. Usually even numbered gauge coils are seen. I have a hard enough time with coils deforming with 28g so I’ll usually twist the 28g material for non-clapton coils. I no longer use any single core, claptoned coil.
If your 2 coil legs face the same direction, you have a 1/2 wrap. If they face in opposite directions you have a full coil wrap.
If it’s 2 coils, halve the resistance shown.
Spaced coils are easier to work with but both spaced and contact will work with TC or Replay.
I always dry burn (low glow) every single coil I make, regardless of material. It burns off machining oils, and human salts.
After all that, I’d go with the 26g, you did that right.
The amount of wraps is what’s needed to get your target resistant with the info you have inputted. Essentially because it’s a dual coil setup to get 1.8ohm each coil is going to be 3.6ohm while also using a gauge and inner ID much more suited to lower resistance. The one thing you left alone is the most important thing you need to change as this needs to be changed to the resistance you are hoping for.
Like @Wayneo I use the Wire Wizard so you should follow his advice as I can’t add anything further.
@Wayneo and @Timwis thanks a lot for that guidance - that was very helpful. When I shifted over to the wire wizard page, I entered:
ID - 3mm
Wraps = 6.5
Legs = 5mm
Wrap Space = 0.1
Single Round Wire
SS316
Gauge = 25
This data yielded a resistance = 0.403 Ohms (0.201 for a pair), which will be right in my wheelhouse. Changing only to 26 gauge yields 0.496 (0.248 for a pair) - also right in my wheelhouse. Thanks a lot fellas - sounds like either would be a great choice for me. Have a good day man.
Either way, you’ll find you’re in the ballpark. I see you left 2 defaults.
Here’s like a secret tip most probably never knew. And BTW the creator of steam-engine (Lars) was a user on the evolv forum. If you swap the ‘www’ with ‘blog’ there are some nuggets there. So, back to the ‘legs’, just read this.
@Wayneo and @Timwis Thanks so much for the help. I’ve bookmarked the Steam Engine blog page, and read the piece on leg length.
You mentioned:
Is this the same Lars that I believe created ELR?
Fellas, all your help makes me glad that I joined Vaping Community - @Grubby should be proud, and my Thanks to him too for making this all possible. It’s folks like you that make it a community.
