Mechs ohm laws wire choice is over whelming

[stols001]

When you use double coils they need to be of equal resistance.

I really understand your desire for flavor, but using BOTH is unsafe as the resistance is HALVED.

If you can mount one diagonally across both coils, then your resistance will be probably about 0.214 (or close, depending on leg length).

Vape it on a regulated mod and see how it performs. If it's okay, then you could probably try it on a mech.

If you can afford a single coil atomizer, that might be a good idea for you. Less confusion, worry, etc. Really, even something inexpensive. Your dual coil deck isn't going anywhere.

I'm concerned that this is that hard to grasp. Either you are getting "fixed" in what you want to do, like "It must be these coils and THIS atomizer and LOW resistance." Or you are having trouble with really simple concepts. I'm not even talking about Ohm's law, but the fact that you are using two coils that aren't of the same resistance (although they MAY be close enough to count) and halving your resistance when you use dual coils.

Please, if there's any way you can get (decent) real world assistance you should, even if it's a different vape shop.

I know how to divide dual coils

No other shops around build I've asked if these in dual would work and they said they don't knownthey don't use mechs only mymain shop does and they would rather build for me then teach me

I really don't want to buy a new rda

Did you measure the resistance of each coil individually, they need to be as close to identical in resistance as possible.
And again, is the .212Ω both coils measure together/ total resistance?

Correct, when using a mechanical 4.2v / resistance = amp
Because of the mass of metal in the coils voltage drop using a single cell mechanical will be significant.
Which if all things were perfect would be about 80w to the coils / 40w each, but will likely be closer to 60w / 30w each and less as the battery voltage depletes.

So you could take the same delivery device put it on a regulated & try it from 50w up to 75w, this will be a close representation of what to expect.

Again, not trying to be rude, but, if you're this confused you really should consider taking several steps back.

Like I said each tiger is .36 but in dual it's .212

I haven't tested both coils individually just both once I threw them in the rabbit i will test both individually later after work

If all fails I should be able to find some .85 k1 Claptons locally

I've seemed to scared you all away

 

[Asbestos4004]

"scared" away? I don't think that's the right term. Frustrated away might be more appropriate. You have a gift for ignoring good, solid advice.

You have a regulated device? Put the atty on there and dry-fire it with the coils installed. Just a few brief pulses, just until they just barely start to glow. Do they do so (relatively) evenly? Good, that's probably close enough. How will it vape? If your mod has a "bypass" mode, that's essentially a mech but with protections. Otherwise, set it to about 3.8v to account for volt drop/battery sag (that's 68w at .212) and see how you like it. That's basically how it would vape on a mech mod, maybe a little bit harder on a fresh battery, and it will peter out as the voltage tapers off.

Want and need are two different things.

After reading this thread I think you need to buy a single coil rda first as well as some round kanthal wire and stick with the basics. You are't ready for dual coils yet, let alone fancy claptons when you don't even understand how a basic coil will work. Buy a clone for 10 bucks and some 26 guage kanthal and forget the other stuff for now. And don't think about using that mech until you are comfortable building coils and vaping them on a regulated mod first.

All of my builds on any of my attys can be swapped from a regulated mod to a mech and vape perfectly fine and well under the limits of my battery, and I don't need claptons at all. Your first builds should be the same. Seems to me you are chasing the hype by diving in head first. A dead rabbit is not a good atomizer for a beginner. It is designed for cloud chasing and that is something you need to work your way up to.

The atomizer plays a huge role in what kind of vape you get. If you want flavor you can get it with a smaller chambered, single coil atomizer with smaller airflow that doesn't require large exotic coils and high or unsafe power. You can still get lots of vapor with a setup like this. Don't worry about the rabbit for now. It will be there when you are ready for it.

This will just not end well.

I've been buying premades for my reload for months now I get how to divide coils in half I under stand 4.2v/ ohms = amp

What am I not understanding because I never wrapped I don't know anything?

What else should I know about mechs takewrapping coils out the equaison

 

[mcclintock]

RE the subject line, actually wire choice is far more limited with a mech for a particular goal because only one gauge and wire length (wraps/dia.) for each wire type (composition and fanciness) will provide optimum results towards that goal. Regulated has a huge number of choices because it doesn't hardly matter, you can make a low power coil out of thickish wire or a high power one from (much more of) thin wire.

RE the posts, if you're not trying to push the limits (or what you're already doing happens to push the limits) then mech is easy. If you insist on something that's going to push a limit, expect to edge up to it or abandon that approach.

As to SS wire on a mech, expect to use more wraps of thinner wire. This is good because they can go into some very thick wire otherwise. As to Claptons, the only one I have is 1.4 ohm (in a prebuilt head), even they can vary.

Like I said each tiger is .36 but in dual it's .212

That is mathematically impossible. Which means whatever you are using to measure resistance is inaccurate at those levels. IF we assume the 0.36 is accurate for each coil individually, then the total resistance HAS to be 0.18 making your current 23.3A. However since we know for a fact based on your readings, that your meter is reading higher than expected we cannot be for certain that the 0.36 is accurate either. It is highly possible that it is reading both numbers higher than it should meaning your total actual resistance is even lower than 0.18.

Now I will add that it is theoretically possible that the posts are adding enough resistance on their own to throw off the calculations vs measuring since we are not factoring those in with the math.

Well on an alien paranormal minikin battle star voopoo drag it's still .21

But I will see what each coil is really reading

My biggest confusion is how do you know if it to much metal with long ramp up and what not

Is there like an amp to watts equasion

I don't want to buy a single coil rda this hugo squeezer with 20700s and rabbit I got 70 bucks wrapped up i don't want to buy anything more

I stared tinkering with vape tool so more wraps =higher resistance I watched Sherlock ohms video cleared up gauges for me

Noticed In vape tool there's always like a wattage say 40 to 90 bar on the bottom I take it that means vaped between those watts?

Don't use a mech until wrapping coils is second nature, you can hit exactly the resistance you want every time and it's been so long since you grounded out on a barrel or top cap you can't remember when it was.

 

[ScottP]

Then that means one of two things. Either the coils individually are actually 0.42ohm, or 0.21 is the lowest resistance those devices can measure. I am leaning toward the first option. Once you measure individually we will know for sure.

 

[fifamymaingame]

I've never done that now so would 2 316l 26 gauge 8 wraps at .317 going to have long ramp u time

You were supposed to do that first.

My biggest confusion is how do you know if it to much metal with long ramp up and what not

Is there like an amp to watts equasion

Yes, there is. Sort of. It's a calculation that produces thermal mass of an object. Heat capacity is what it's called and It's the amount of energy in Joules needed to increase the temperature of a given object by 1 degree Celsius.

You aren't ready for that by a long shot.

You can use the Steam Engine website to calculate it, but for now, just take our word for it: A coil with more metal mass takes more energy to raise its temperature by 1 degree Celsius. And that the coil you're trying so desperately to use takes too much energy to get a good vape out of it with the energy source you're trying to use.

For now, just use one coil in your Rabbit.
