Micro coils and ohms description

[jwat82]

Twisted 30ga kanthal
9/8 wrap around 5/64 drill bit
1.3 ohms
Cotton, organic cotton

My favorite coil of the billion or so since I got it two days ago. Waiting on some 26ga kanthal.

I know the knowledge is somewhere. Can you tell me if there's a good YouTube tutorial on the twisted wire coils? What's the benefit--is the surface area somehow greater than with straight wire?

Usually... it's what you do when you've run out of thicker wire. ;-)

Some believe that there is an increased surface area vs. a thicker wire with similar wraps/diameter/ohms - hence more vapor production. You can try one and decide for yourself.

Bump to find. thanks

Micro Coils to increase Vapor, flavor & TH

Pictures of dual coils, tri coils, quad coils, and IIRC, penta coils. It'll take a long time to get through it, but it's worth it.

Bumping this so new people can find it. I finally subscribed to it so I can find it when I need it. Karen, thanks again for starting this. This is a VERY helpful resource.

Thanks again from me too, exactly what I've been looking for!

Karen, this has been SO useful that I compiled it into a spreadsheet for quick reference, and converted inside diameters to both decimal inches and mm's. Thank you, thank you, for ALL the work you put into this forum

For anyone interested, it's an Excel™ spreadsheet and I uploaded it to Google™ docs. The spreadsheet is here if you want to view or download it, and/or print it. Current through post #147

ETA: Cleanup up format and removed some duplicates

That is a great spreadsheet. Thank you.

Terrific to have all the successful (and not so successful) data formatted, by gauge and mandrel, for quick reference.

Nice work AP.

Fantastic job Bill!

Thank you very much for your time and effort to compile the information into a better format!

Well, looking over the spreadsheet I uploaded yesterday, I was truly embarassed At any rate, I reformated, i.e., moved the columns into a sensible order, and (hopefully) removed the duplicates. Someone please let me know if I boogered it beyond any usefulness.

With luck, the original link still works, at least, it does for me.

I love it Bill! Very easy to pick the wire gauge you have and go from there!

Wonderful to have the spreadsheet!

Thank You AP! This is just great. I bookmarked the link for easy reference. Thanks for taking the time to put this together.

Although not difficult to sort the original, V2 is far superior. The extra effort, in the name of clarity... is well commendable.

Great info - thanks for compiling.

My small addition:

30 gauge Kanthal A1 - round
* Two strands tightly twisted into one (using the drill method)
Wrapped on a 1/8" Phillips precision screwdriver
* Wraps not touching each other
5 wraps = ~.485Ω

Great spreadsheet AP!!! Thank you for compiling this. Going in my rebuild kit...
