IGO-L help with simple coil

[levisdaddy]

I made a perfect 1.3ohm coil on my first build last week. it was mystery wire and i have since tossed it.
I have several diff gauges from 26-32, eko and 3mm silica.
i need some help, my last 4 builds have been terrible.
What gauge kanthal wire and how many wraps to reach 1.3ohm? this worked so well on both a vamo and a mech that i wish to emulate the results but keep messing up.

id prefer to not do micro, i am open to it, just never tried. I think ill be using the 3mm silica doubled over.

any suggestions, tips and direction would be greatly appreciated. much thanks

I find it particularly difficult to secure a freehand basic coil on silica on my igo-l. Usually when securing the leads on the post the coils get all wonky.

if you're dead set on using silica and a standard coil, try wrapping the coil around a drill bit or something similar and then attach your coil with it still wrapped on the drill bit, then then thread the silica through. Not sure exactly how many wraps or what kind of wire you'll need.

I highly suggest trying this same method with a micro coil and cotton ball wick, Ive found that a 1.3 ohm micro coil will out perform a standard 1.3 ohm coil and its generally easier to attach it to your atty.

good call X, its been suggested to me a couple times. i shouldnt be stubborn and just go with it. my first coil worked so well, i guess i should stop chasing it and go micro

Try it! I'm sure you'll like it

I hope to build my first coil in a couple of hours. Waiting for the IGo L to arrive USPS. I will try the method levi suggested using a jeweler screw driver instead of a drill bit. The only crappy thing is that I don't have my multimeter, so I'm just gonna think happy thoughts on this one and see what happens.

I'll let you know how it works out.

why not just wind a coil, mount it and measure? if it's too low, add more...if it's too high take some out?

If you've got an android phone, download the free app from google play, vapors toolbox.
It is invaluable to us rebuilding folk.
U select what ga wire you are going to use, and the diameter of the coil and it will tell you how many wraps to do and how long of a piece you will need.

i gotta download that!

Made a 1.5ohm microcoil (my first one!) using 30g wire around a drill bit. took some time and patience to get all the wraps to touch. kept heatnig it up and squeezing with tweezers over and over again for 20+ min. had to do it again when i tried to tread a doubled over piece of silica. the ohms were jumping all over the place from 5 all the way down to 1.5 while i worked em together.
It works well, but my airflow is poor. this morning, at a friends advice, i took a corkscrew to the hole and widened it ever so slightly and it improved. Someone offered to drill it out for me, and once my igo-w comes in from the mainland ill ask him to do both.

I'm not finding that app.

Search Play store for vaper's toolbox , not vapor.

Search google play for "vapers tool"
Just found it that way a second ago.

Ahha the spelling does make a difference thanks.

So I wrap my coils freehand. I use an alligator clip to hold the wire to my silica. I then take it slow while wrapping so my coil is in good shape by the time I put it on an RBA. The drill bit method makes wrapping the resistance wire easier, but I found it to be more difficult to get the silica through it.

Didn't realize until just now we posted at the same time.....= )

The app is really cool. It has lots of neat features.
For coil diameter, just select the size of whatever it is you are wrapping the wire around.
Only issue I had was the app crashed a couple times. It was the first version though, and I have since updated it.

i am digging the app. havent used it yet in a real application of a build. but soon i shall

I use microcoils exclusively on my IGO-l at this point... for two reasons... 1) once it's wrapped and mounted, it'll last a long time. Micros, due to the way they are built and put together, are really durable... I use cotton wicks, so once the cotton is fouled a bit, takes a couple of minutes to pull the cotton, dry burn to clean the coil up, then rewick with some fresh cotton. That single microcoil could last a LOOOONG time.

The second reason why I use micos is that the WORK AWESOME!!! Seriously.... the micro in my IGO-l puts out a good, thick vapor that's smooth and tasty. Remember that with a micro, you are heating up a ton more coil wire than in a 'traditional' coil at the same resistance... which would be fewer wraps with higher resistance wire... so you are vaporizing more juice, on a coil that is 'cooler' (in the sense that any one point a micro will be cooler than on a traditional coil... provided the resistance and power delivered is the same).

Now, 1.3 is usually my target too... and I've found that 10 wraps of 28g Kanthal, wrapped on a 1/16 drill bit (around 1.5mm), gets me to 1.3 fairly reliably. And it never jumps. The ONLY time I got my resistance jumping around was that one of the legs was getting a little loose on its post.

As for your problem with the jumping resistance... that almost sounds like an issue with the contact with the posts rather than an issue with the coil.
