Billow V2 rant

[billgharley]

Sorry, but need to vent a bit about my Billow V2 which I just received yesterday. I realize that the problems I'm having are not the rta's fault, but my own

Nice clear and well built rta and I like it. I've only built on the Subtank mini which I've had since it first hit the market, and have mastered the perfect build on it.

The Billow V2 is my first dual coil rta.
I think that the negative posts should be offset in height so you can more easily get the 2nd coil in. I know that I can raise the first coil up enough to get the 2nd in, but it's a PITA. I fubar'd my first build and scrapped it and tried again.
I took my time, was very careful and made sure everything was as good as I could get it. Certainly not perfect, but good enough hopefully.

It's frustrating that the screws cut my wire. I''m using 26g kanthal, it took 2 tries before I finally got it (so I thought).

1st coil.

2nd coil.

After cotton installed, juiced up, put back together, and vaping, everything was great...for about 1 minute.
Then ohms started bouncing around from .6 to 1.6.

Time to take it apart and give to another go.
The build deck is pretty small, so I guess I need to take more time and keep trying until I get it right.

Thanks for listening, and any suggestions would be much appreciated.

Well, that was an easy fix. Tightened the screws on the posts and that fixed it. .5 ohms and no bouncing. Either the screws are loosening, or I'm not tightening enough in fear of cutting the coil wires.
Working fine now with big airflow, great flavor, and big clouds. This thing isn't dry hitting at all, unlike the fist version of the subtank, so I'm a pretty happy camper right now.

I have alot of dual coil RTAs and I have to bit down pretty hard on them with the screws in order to keep a consistant resisstance. Glad you figured it out.

Don't know if it will help you with future builds, but I'll throw in my

After I get my first coil installed, I push it down. That way the leads for my second coil I can get on top of the first one instead of through it or beneath it.

I also wrap my coils in the opposite direction that you did so my positive lead is coming off the top of the coil, and negative is coming off the bottom. Often, the positive block is raised so I find it works better that way. If the positive block isn't raised, then it doesn't matter really.

Also EHPro gives you the worst screws. Sand the bottoms of the screws and they won't cut the wire.

Thanks, never thought about winding the coils the opposite way. I'm right-handed and I guess it just feels natural to wind it that way. I'll try the other way and see how it goes.

Thanks @roxynoodle .

I'm a weird ambidextrous person who favors my right hand and yet wraps lefthanded coils . One thing that helps me is to wrap the same way but start with my lead the other way on my drill bit. Usually I wrap with my lead starting under the bit, but if I need an opposite coil to my usual one, I'll start with my lead on the top of the bit (you may need to do the reverse of that).

@roxynoodle As far as pushing the first coil down, I tried that and had a tough time getting that 2nd one in. Pushed it up and it was easier. Your mileage may vary of course...I'm learning dual coil builds, so take that with a grain of salt
Thanks for the reply roxy.

Whatever works for you is good

roxy, I did exactly as you suggested...wrapped the coil in the opposite direction as normal. Negative lead coming off the bottom worked out perfectly. Thanks for the suggestion @roxynoodle

heard some spitback issues, have you ever had ?

 

[billgharley]

No spitting issues at all. I've seen posts about people saying wicking is a bit tricky, but I haven't found that to be the case. Not too much, just a little wick in the top of the juice channel, and I'm good to go.
