I understand about wire sizes with regards to gauge, but....

[NotNew2VapingNow]

is there any correlation between twisted wires & the guage?

for instance, if you do a double 28, what, approximately, would the resulting gauge of the twisted wire be?

is there a formula for figuring it out, or do you just wing it?

more specifically, if I'm planning on starting coil building with 22 & 24, what gauge wire, tripled, would approximate the 22 or 24..if this makes sense...

1. I wouldn't start with 22 or 24.

2. Don't wing it, get an ohm meter.

3. I'm hoping someone with more experience twisting will chime in with an x-twisted-by-y equals z post - that would actually be a great resource to have, though I suspect it's highly dependent on tightness of the wraps...

Steam engine app works well there's a section on twisted wire where it tells you the resistance of the wires your twisting.

 

[NotNew2VapingNow]

as far as starting with 22 or 24, that's just for a standard coils...I'll get those perfected before moving on to the twisted, dozer tracks, braided, etc

As @richardward77 mentioned, utilize http://www.steam-engine.org/coil.asp?. Use it as a guideline for your coil build's, including twisted and parallel. However, verify your builds with an Ohm reader, for proper resistance and/or shorts.

Well said about ohm reader as iv done few builds and they have been slightly off from what steam engine have predicted.

Yep there is a simple formula.
Area = radius * radius * pi

Mmmm, tasty pi

There's no way to know what gauge your twisted wire will be because it totally depends on how much you twist it. If you twist the wire until it snaps, flip it around and twist it until it snaps again (maximum twistage) then generally it'll move up a size. So 2 strands of 24 gauge twisted as tight as possible usually ends up about the size of 23g (or just a hair smaller than 22g). The behavior is a bit difficult to predict. Sometimes it will read like a wire with the same total diameter, sometimes the resistance will reflect more like a parallel build. Always use an ohm reader, a coil is gonna act however it wants and its risky to assume that you know exactly what that means. Or at the very least, use it on a regulated device just to be safe

ohm meter is already on the way...I prefer my face just the way it is, thank you very much

Each time you double the wire, you get a wire size equivalent of 3 larger. eg, double 28ga = 25ga or double 22ga = 19ga. either way, 22 is pretty big stuff for just starting out. Twisting the wire does do a bit of funny stuff to the wire, as when you twist the wire, it gets a higher resistance because of the current taking a longer route through your coil. Either way, use a regulated mod or an ohmmeter.
