I'm about to build a new coil, but I think I've figured out why I've been disappointed with the 1.7 ohm coil I built last night. I was pushing it at 10 watts or even a little higher thinking that would make it gurgle less. I'm not sure if it's actually gurgling to be honest. At above 10 watts it makes a noise that's just different sounding. And after just one day at that wattage, it was tasting stale. So, I dropped the wattage this afternoon down to 9.8 watts/4.1 ohm and it's quieter, makes less noise and tastes infinity better.

Still, I'm going to go for a coil that is less than 1.7 ohm and we'll see how I do.

Coil talk over for the moment. Carry on. No really, carry on!

So tonights adventure with wire. I built three coils. One with 9 wraps. Too high. One with 7 wraps. Too low. One with 8 wraps. Perfect. It came out a tad over 1.5 ohms. I wicked her, primed her, put the KFL+ all back together, filler her up and let her sit for 5 minutes before taking a vape. So far, much much better than last night's adventure with wire. Since I'm a picture guy, here's tonight build:

As you saw, I got 28 gauge Kanthal in the mail today and since I'm still new to this coil building business, I decided to build a new coil. This time, it didn't take any time. 28 gauge, 9 wraps around a 2mm bit and I think this one turned out really well. I wanted the coil to be between 1.5 - 1.7 ohm and it came it at 1.7 ohm.

Nice looking coil. The legs are a bit too close to the deck for comfort, but I started using a Kayfun on a mechanical, and like I mentioned earlier, I did end up with a short. Building with the legs coming down from the top provides an extra margin of safety. Nothing like a vertical leg to clear the canyon between the positive and negative posts on the deck. Then again, you're using it on a P3, and there's far less to worry about.

One bit of advice to try next time... Try making the coil go diagonally across the deck, so your wick can go down the corner and lay across the deck (without blocking the juice channels).

As for the flooding/gurgling, that goes back to what I mentioned before. You're sucking in too much juice and not burning enough off. Increasing the wattage or opening the airflow are the only solutions - it's physics after all, and you cannot change the laws of physics.

Regarding the advice to blow through the drip tip to clear the extra juice, it usually backfires on you. First of all, if it's gurgling, you've filled the chamber with juice. Blowing through the tip won't empty the chamber, just the overflow. You still have to burn off the excess. If you do blow through the tip, do so VERY slowly and gently, otherwise you're pushing air into the tank and pressurizing the tank, and that in turn forces even more juice into the chamber. If you see a bubble in the tank when you blow through the tip, you've just defeated what you're trying to do.

More air, more power, inhale more gently... you get the idea.

Thanks John. Tonight's coil is gurgling too, so I definitely need to figure out how to avoid that. I just bumped watts up to 12. We'll see if that helps and I'll try to put the coil on the diagonal next coil I make (likely tomorrow night. The first coil I made was attached from the top, and it worked better, so I'll do that again as well.

SR, John correctly observed the tags coming from the terminal screws potentially touching your chimney and causing a short. Looks like you cut them with cutters of some sort. Next time, twist the legs off. They will trim much closer to the screw and wont protrude so much.

No, I twisted the legs off, which worked well or at least I thought it did......

As I was wrapping, I cound 8, but you could certainly be right. I'd really like the coil to be in the 1.4 to 1.5 range, so tomorrow night, I'll build one again. Sigh.......I'm not sure I'm ever going to get it down to the point where it's consistent.

You will get it...

Or you could always go back to the sub par chicom prebuilt stuff.

Keep at it Sir Rod!!!

I'm frustrated. So I emptied the KFL+, cleanted it, threw the coil away and put on my Silo as it's late and I have to go to bed and just don't want to fuss with it anymore tonight.

JohnDo. I'm confused about your suggestion to put the coil on the diagonal? I thought the wick had to lay on the juice channel inside the chimney, which would be fed by the juice channel outside the chimney? If the wick isn't laying on the inside channel, won't it gurgle even more as wouldn't even more juice enter the chamber?

Sir Rod is beyond confused at the moment. The first coil I built when I got the KFL+ last week worked so much better...........Sigh.........

SR, Confucius say confusion is bad. Don't mess with diagonal coils now. It is not important. Just focus on the straight coils like you've been doing. No point in introducing more alternatives.
