Size of coils

[Ding]

Is there a standard size to wrap your coils.I mean like on a 1/8th inch rod,5/32 rod or is it up to you or does it depend on your type of replacement heads.I am using vivi nova and stardust 2.0 heads so far.I get the amount of wraps VS ohms thing.I have some 30 gauge a-1 kanthal and 2mm wick,figured I'd split the difference from 32G and 28G kanthal.

Is the size of the wrap made just to fit the wick or is there a standard or does it matter.

There is no standard size. It all depends on your atty and what you plan to wick it with. You might want to look into the Micro Coil thread though. I've been vaping on a micro coil for a month now and I've found it to be the best for me.

Here's a size chart to define the inside diameter of a micro coil :

Here's a picture of a .055" 30 ga 2.2 ohm micro coil:

what did u wrap that around to get it so small?

That is .055" music wire. You could use a 16 ga luer lock needle or a 1/16" drill bit and it will be very close . Just don't wanna go much bigger or performance will start to decline.

This is the jig I use with the piece of music wire:

Here's a video of how I do em up with that jig:

I switched back to 30ga wire and 10 wraps. It yields a 1.5 ish ohm micro coil that vapes unbelievably awesome

Would a 15 gauge blunt tip needle be a micro coil?

 

[super_X_drifter]

It's a little larger than optimum but should still vape ok. Try a 1/16" drill bit if you have one

Here you go:
Metric drill bit set

From 1.05 to 2mm. They're probably crap drill bits, but for $3.99, you're probably set for most coils you'd want to build.

So generally, if I need not have access to a drill bit, is there a gauge of needle that is OK to use? - I've noticed that various vendors sell them in multiple gauge, like 14-20g.

If you have any of those micro screw drivers laying around your house, One of those will work fine also. You know the small screwdriver kits that everyone has laying somewhere in the house? Usually one of those will work perfectly fine.

You could use a toothpick possibly? but not sure how that would hold up never tried it.

When i first got into making micro coils i actually used a small threaded screw and let the screw do the wrapping and i twisted the screw with my fingers and it pulled the wire perfectly into the threads and when you go to heat it up and compress it, it might be tricky.

Pretty much any small household item or piece of hardware you have laying around will be fine. You don't have to be dead set accurate.

Yes, 14-20g will give you a range of about 0.9 to 2mm diameter coils.

Pretty much any small household item or piece of hardware you have laying around will be fine. You don't have to be dead set accurate.

Just keep track of what you're using for consistency.

will a smaller micro coil produce a warmer vape? if I want less TH and heat should I opt for bigger size coils?

Perhaps other vapers with more experience under their belts can give a better answer, but IN GENERAL, yes, for the most part, I've found that with equal resistance, using the same gauge of wire, a micro coil will give me a warmer vape than a standard coil.

A micro coil is a very efficient coil because of heat transfer and surface area in contact with wick.

To reduce heat, you would build it to higher resistance - add wraps.

To reduce TH, you would position your coil directly behind the airhole, away from the posts and out by the edge of the deck and adjust the elevation of your coil in relation to the air hole to suit your TH preference.

Higher = more TH
Lower = less TH

too much wick in chamber can also raise TH levels.

Here is an ideal, 1.3 - 1.5 ohm micro coil and cotton wick in a cyclone ( very similar to IGO type RBAs )

I just watched all your YT videos very helpful even though I don't have a REO, thanks.

How come on the chart it says for a VV device aim for a minimum of 12 wraps and a resistance of 2.0 ohms or higher?

I heard some people claim that thicker wire produces better flavor than thinner gauge wire that's why I always try to make all my coils with the thickest wire that my device can read even though I get less ranges to vape with, is there any truth to this?

I vape on a KFL+ and the deck i'm working on somewhat limited in coil length

 

[super_X_drifter]

Ron, thanks man.

I hear a lot of VV devices won't fire below 1.5 ohms.

In other words, I think they cut off somewhere between 10 - 20 watts so if your resistance is too low it won't work.

Additionally, with the volts on tap with stacked batteries, you can use it to fire longer higher resistance coils for excellent results
