1st Dripper Coil Build - Igo W4

[molimelight]

I recently purchase the Igo W4 to try out dripping. I've been building coils for my Protanks so the coil build wasn't hard. Wound up with 2.7 but my target is lower, say 1.8 or so. It was a little tricky in setting the coil up as the Igo is pretty small. I've included a photo of the build and I have some questions: 1) Does the coil and cotton wick setup look right for dripping? Improvements? 2) When you drip do you try and soak the wick or just drip X number of drops into it? 3) Compared to the same juice on my Protanks, the hits have been very warm and harsh with not a lot of vapor. Definitely a hard throat hit. I'm vaping at 8.5 watts. I've heard that the Igo RBAs perform better when drilled out for more air. Any ideas on that? 4) Should there be juice in the bottom of the W4? IE is the wick getting enough juice? Don't hold back on criticism or ideas. It's great having all of the knowledge in this place as learning resource.

Nice. I remember my first.

All IGOs (except the S) are actually pretty big and have plenty of room to work with. It's all relative; you get used to working in such a confined space regardless of the device.

1) I'd make your coil legs equal length, its okay if the coil is off center to accomplish this. Look at pictures of coil builds and you'll see they are centered on the two posts they are mounted to.

2) Fill up the deck with juice if you want the most possible vape time from a single fill. It may gurgle to start, but it still should vape well.

3) Align the air hole so it directs the air right onto the coil. Make sure the coil is vertically at the same height as the air hole. Drill out the air hole a bit if you are vaping over 12 watts. The draw should be fairly loose.

4) See #2. Juice it up! Just not so much it leaks out the air hole.


Otherwise looks good.

Thanks CloudZ, that actually answers all of my questions! I think that one difference between this and the Protank 2 Mini and Aerotanks I've been using is the nicotine hits harder. It's also a much warmer vape. As long as I know I'm on the right track I can keep building and experimenting a little bit.

I've taken the time to work my way through this thread. Entertaining and informative! Thanks again.

Not sure why you are getting a harsh throat hit. My Igos are all pretty mild.

Probably the difference is that I'm not really building micro coils on mine. I just wrap some 30 or 32 ga wire around a 1/16" drill bit (5 to 8 wraps depending on the wire and desired resistance) and mount the coil. No torching, tweezing or squeezing of the coil - so I have some small gaps in the coil. And it looks like I use less cotton than you. I cut one end very close to the coil and leave a short tail on the other end to touch the deck. I have also drilled all of my Igo atomizers. Once the wick is saturated completely, I usually add about 10 drops whenever I start to get the slightest burning.

Anyway - I get a pretty good vape with no harshness on all of my Igos.

Thanks gpjoe. I'll try a regular coil next and try trimming the wick down. What size did you drill your Igos out to?

Mine are at 3/32 and could be a a little bigger. Go slow. You can always make the holes larger but making them smaller is tough.

Just figured I'd chime in on this since I have some experience with it. My IGO-L is drilled out to 1/16" which is perfect for me. I knew this would be too airy on the IGO-W with 2 holes, so I bought a 1.2 mm drill bit. It would not chuck up in the only drill I have access to, so I went with the 1/16" anyway. Just as I suspected, too airy. I tried covering the holes partially with tape but wasn't happy with it. So I bought some JB Steel Stik, filled the holes (it was not as easy as it seemed!), and re drilled by twisting the bit in my fingers. What a mess and a hassle though. I recommend finding a way to do it right the first time.

It does seem like a fairly tight draw so I'll start at 1/32. If that's not good enough, the next non-metric size is 3/64, so when I buy the 1/32 bit I'll buy one of those also. I have a 1/16 and a 5/64 if I have to take the next steps. As always, thanks for the help!

I'll get to it right after this next snow storm...
