Wire gauges when twisted?

[jayyco]

Im planning on making a triple twisted 28 gauge wire, and was wondering, around what gauge would it come out to??

Edit: Im pretty sure it comes out to 22 gauge

Gauge wise, not sure, but the resistance will be halved.

Triple twisted - So the resistance will be divided by three.

Keep in mind that you cant simply divide by three, because each inch of twisted wire will use more than one inch of wire in each strand, because of the helical shape of each wire.

So using the temco value of 0.439 ohms per inch for 28awg.

Divide by three you get 0.146 ohms per inch.

Fully twisted wire contains more than 1 inch per strand per inch however. Depending on how you twist your wire this will vary.

So as a ballpark figure I would say it is equivalent to 23 awg wire, which has a resistance of 0.153 ohms per inch.

You are correct if you twist first then cut one inch. If you cut three 1 inch pieces first, then twist the the math works. Since I doubt people are going to have three identical rolls of wire to twist then cut, my assumption is that people will be cutting three pieces first.

He wanted to know what equivalent resistance or gauge it was. Going by resistance per inch.. it doesnt make sense to equivilate the original length of the wires rather than the final length of the twisted wire....

Does it really make that much sense to twist 2 or 3 pieces of wire together to make a coil?

I was thinking of tightly twisting 2 pieces of 32 AWG wire for a single coil setup on my Kayfun ... Then I thought; why not just use a piece of thicker wire instead of 2 pieces of the thin 32 AWG.

I maybe missing something here, but what's the advantage of using 2 pieces of thin wire wraped around each other vs a single piece of thick wire (as long as the ohms are the same on both)?

when twisting wires, the original length becomes reduced but still contains the same amount of wire
example: start with 3 strands @ 10' untwisted, twist the wire and that 10' becomes 8' in length .... a 20% loss in length but its still "10" feet resistance wise....

the idea is to have all the grooves and nooks hold juice allowing for a more intence vapor in the first second or so....

the wire "acts" like a wick

Do you honestly, in your heart, believe that ... or is that something that you read somewhere?

Correct, thats what I said in my first post. To compare the twisted wire to a gauge however, which is what the OP asked for, you need to compare like lengths of wire.

So for example, if I want to compare 1 inch of twisted wire to a gauge of wire indicated by resistance per inch, then I would need to compare what 1 inch of that twisted wire is compared to 1 inch of X gauge wire. It makes no sense to compare what the original wire length was before twisting to the gauge in question. 1 inch to 1 inch. Not 1 inch minus 10% to 1 inch.

IMO twisted wire is inferior to simple low gauge wire. Twisting wire DOES make a difference.

For instance, I have done triple twisted 26 gauge compared to 22 gauge wire. They have almost the exact same resistance per inch. In using both to build 0.25 ohm builds, the 22 gauge beat the triple twisted 26 hands down in both flavor and vapor.

However, when low gauge wire is hard to come by, twisted wire is an easy alternative for somebody who has an abundance of higher gauge wire.

Nataani ... Thanks for the explanation

I am not going to waste my time twisting wire together in order to invent some new 'super-coil' that will revolutionize vaping as we currently know it

its been done... its called mundys magic wire, or magic mundys wire... i forget... but its been done...

This Is for more of experimenting, I don't have 22 gauge wire at the moment so I wanted to try twisting my 28 gauge wire. Honestly it's more of an experiment, I'm the kind of guy that likes to rebuild his rda coil every week. I want to know the difference in every coil make to figure out what I personally like the best.

Experimenting with different coils is half the fun of having an RDA! Just because I think that plain wire beats twisted wire, doesn't mean I don't experiment with different stuff .

Gladly accepting all different kinds of unwanted wire... will gladly put it to good use... i mean ive got a triple twisted 30 gauge right now... because i have so much 30 gauge n the mrs is hard on the vape purchases... only as needed

I honestly believe it. I am vaping on 2 strand 28 gauge twisted right now. It is pretty rockin!
