My first attempt at RDA

[iheartvape]

So I finally sat down today and actually attempted at a rebuild for the first time. I was aiming for 2.5ohm coil but ended up with a 3.0 ohm instead. I'm using 32g Kanthal and cotton as a wick on a Octupus RDA. I did 8 wraps on the coil I think.

Any advice from some of you veterans out there what I need to do to get it down to 2.5 or 2.2 ohms? I read a thread a few days ago that mentioned how many wraps for different ohm levels, but can't find it for the life of me.

Other then not hitting my goal on ohms, it was a success, and tastes awesome!

There is a thread where Rixter calculated approx ohms per wrap. Of course it can vary with wire thickness and size.

I would lose one wrap and remeasure. Might need to drop 2 wraps to get where you want

Did you make sure the coil is bunched together nicely?

[iheartvape]

Yeah I squeezed the coils or compressed them with pliers they didn't stay compressed very well. I also had a hard time trying to get the cotton threaded through without messing the coil up.

There is a great ap for your phone called 'Vaper's Toolbox'. Input your gauge and desired resistance, and it tells you how many wraps and what length to use.

That's an adriod app?

Ohhhh that's awesome!!! Thanks 3Rutez!!!!

You need to heat the coil while compressing it

Dang I knew I forgot to do something!

Yeah, android and iPhone I believe.

Hmm. I don't see it in the App Store. I'll look again. Thanks

Heart are you trying to do a micro coil? Or just a regular coil? There is no need to compress the coil if your doing a standard wrap. They just need to be spaced out evenly. Also if you take a few less wraps on your next coil you can drop the ohms. 6 wraps of 32g should be about a 2.2 ohm coil. I get .9 with my 26g with 6 wraps. Also are you running cotton thread? Or rolled cotton? Or cotton yarn? Or a cotton ball? What exactly are you using for a coil? You can always go get some beading wire to pull the cotton thread through the coil. If your using rolled or a cotton ball you will want to wrap on the cotton itself and support it with a needle.

Imedic.. I am using 32g Kanthal with a cotton ball that I rip a piece off and roll it between my thumb and finger then thread it through. I'm just trying to do a standard coil for now till I get the hang of it.

Here is a pic of 2 coils I just did. The bottom one I just hand wrapped a piece of cotton, the top one I actually used a little metal rod I had laying around as support for the wire then threaded the cotton through....

Make use your wraps are evenly spaced when you heat it up and that they glow from the middle out and your fine. If you were doing a micro coil you would need to pinch it together but your not so your fine. The top one looks better then the bottom one and you won't get much support with a cotton ball so it will be a lot harder to wrap freehand with it. Try a 1/16 drill bit then slide the cotton through that.

[iheartvape]

I will try that today. Hopefully I have a 1/16 drill bit... Lol
