Struggeling with very poor vaper production on my IGO-W, dual coil build

[Xromill]

Hi!

I just bought a Kamry K100, with an Igo W. The vapor production really excited me when I was watching youtube vids.

So i bought an K100, a good Sony VTC5 battery, 28 gauge coil and of course the Igo W.



I watched some vids and built a dual coil with a q-tip, 28 gauge and 6 wraps. I fired them up, and pinched them with a pair of tweezers. I inserted the cotton. When i started vaping there was almost no vapour. I use a PG based e-liquid.



And yes I know that drilling air holes makes much more vapour, but what I'm getting now is less that half the amount of vapour coming out of a china cigalike.

Is there anything I could do better?

 

[Xromill]

I would be very grateful for any answers!

Welcome to ECF, Xromill...

I would imagine it's not so much your build or atty- although it may be... you don't offer a resistance value - as it may be poor conductivity with your K100.
Do you have a digital multi-meter (DMM) to test the conductivity and battery state of charge... or perhaps at least an in-line volt meter?

 

[Xromill]

At the moment I don't have a multi-meter or ohm reader. So you do not see anything wrong with my build? Any more tips?

Thank you so much

I'd be willing to bet a large part of your problem is the stock Igo-w, the holes are just insanely small on those, really need to be drilled a bit.

Almost looks like the coils are sitting a bit below the lip of the well (hard to see from pic angle), you may try raising them up a bit to the approximate height of the airholes on the cap. Ideally (depending on RDA) the airflow holes should align with the center of the coil both vertically and horizontally (+/- a few mm).

You could also try removing a bit of the cotton that is sitting IN FRONT of the coil, i prefer a clear path for the air straight to the coil (some may disagree).

I suggest getting a good ohm reader and multimeter before doing anything else. That's pretty dangerous without those essential tools.

Thanks for the help. I raised the coils a bit. Did not help that much. I will drill holes when i have access to a drill!

I accidentally used the battery that came with the Kamry K100, and it produced more vapor than the Sony VTC5. Luckily the battery didn't explode! Do you think that there is something wrong with my sony battery? I don't think the battery was fully charged though.

Thanks!

Yeah I really do understand. What a risk. Do you have any idea of the problem with my battery?

You would be able to find that out with a multimeter.

Its like you're in a boat in the middle of the pacific without any navigational tools.

 

[barkfunklerbunk]

And chose not to bring any because you believed you would be just fine.

Lol. Don't rebuild without a meter. Period.

Seems like you don't really care about that, and only care about your battery.

Fyi, you could have a 1 gabillion Amp battery, and a short will still take your hands with it. You've got your priorities completely wrong. Just saying.

Stock air holes on an igo w are 1mm. Drill them to 2mm at least. You will get almost nothing on those air holes.

Get an ohm reader! And 6 wraps on 28 ga is too few. Need more wraps. For 28 ga I like micros or even nanos. Around a q tip is too big IMO for 28ga but really 6 wraps is too few.

With a vtc 5, it will handle almost everything you can build esp with 28ga. But being new, it will help you check for shorts. You arnt going to lose your hands if it vents but you will lose a battery and risk inhaling battery acid and other issues

Pick up a cheapie multi meter from Walmart. Touch the leads together to get the resistance then subtract it from the number you get by touching the positive post and the ground. May not be the most accurate but it'll tell you If u have a short..,, but get some vg juice enlarge the air holes make sure your screws are tight and use way less cotton should be golden

It seems the commonality with this rash of threads concerning those having trouble is the lack of a multimeter...

Advanced personal vaporizer people. New vapers should not jump into the deep end on their first try. I did hours and hours of research before i started to even try building my own coils and that's with an electronics background

Your coils are flooded, your air holes are too small, you're missing an ohm meter, you're missing a multimeter, your battery has not been charged, you have no idea if your amperage is safe and you're lucky that nothing bad has happen.

Gain the proper knowledge and the required equipment and your results will surprise you.

Your voltage is largely determined by your battery, the lower it is in charge then the lower the voltage.

You want your coils relatively level and close to the airholes. You also want them placed in a way where they will be the least restrictive to airflow.

A dual coil is a bit of a challenge for a beginner. I would strongly urge you to consider starting with singles first.

Wicking technique is pretty crucial to getting the best performance. Lots of people, even experienced builders, never get it down because most drippers will function with mediocre wicking. I can't make out your pictures but the main mistake most make is TOO much material. This manifests itself in two ways. First, the density of the wick itself being too much. Next would be the entire amount you have on the deck; people tend to use so much it restricts airflow.

Unless you want to do mouth inhales(in which case you can forget about heavy vapor production anyways), the stock air holes on the IGO are all but useless.

I have an Igo that can hang with all but the most extreme cloud chasing attys, but it is also drilled out to over 3mm.

Lastly, if you didn't know already power is also a big key to vapor production. Unfortunately the Kamry mechs have A LOT of voltage drop, which becomes a lot more apparent when you build low resistance coils (aka sub ohms). But frankly you really shouldn't be playing with any of this without a meter of some sort to test your coils.
