First coil build

[jbish86]

About to build my first deck tonight. Don't have a voltage meter. So, I'm trying to figure out a good and safe coil build that i can get within the 1.5 ohm range. Have 28g and going to use a toothpick for diameter. How many wraps would I need? Guy at vape shop said 5 wraps, but a lot of online sources say 10. Any suggestions? Using a trident rda with panzer blackhawk clone.

you NEED a DVOM or a mod that can check the resistance of the coils...
there are too many ways this thing can go bad and you would have no way of knowing unless you have a way to check the resistance..

If you don't have a way to check your coils with either another mod or a dvm don't do it.

The guy at the vape shop didn't advise you to check the resistance?

As stated,this has bad news written all over it. Go to harbor freight and get a DMM for $5 bucks and save your face man!!!

Then watch youtube to learn how to use it. You can learn anything there. I fixed my fridge and my toilet. LOL

Buy a ohm meter! The injury you save may be your own.

Great advice....please heed it.

Definately get a meter. Ive been using my SVD to check resistance, and a vtc5 in my mech. Got a atomizer ohm meter for $13 on the internet as a backup.

if ur using kanthal a1 wire then for a toothpick (like a 1.5mm diameter) you'd need 9-10 wraps to get in the 1.5 ohm range. Someone correct me if im wrong

You're wrong. Rule #1 is you don't wrap a coil if you can't test it.

I agree with all other posts here, get an ohm reader, saying that I just use my MVP to test my coils.

 

[SMagee]

I'd check it before I fire it up. But that's me

 

[klynnn]

If you don't have a meter how would you know? Are you really willing to chance it? Stupidity pisses me off.

Damn, I was hoping to get this thing vaping tonight. So there is no sure way to make a coil that will be 1.5 or more? Probably won't be able to anyways because my 18650 still isn't fully charged. Been charging for 3+ hrs. It's not hot, but I feel like it should have been charged by now. They don't sell them completely drained.

you will need 30ga, kanthal wire to build a 1.5 ohm coil. six or seven wraps on a 1/16" bit. 28ga. is for subohm builds. get a meter. get some 30ga. and tasteyourjuice.com

eek...just saw your post count and feel bad I didn't welcome you.

Hello! And welcome to ECF, where we care more about you keeping your face than blowing clouds

erm...If you bought your batteries at the same shop that told you to just slap a 5 wrap coil on it...umm...I wouldn't want to guess what shape the batteries might be in.

I totally get wanting to play with your new toys as soon as you get them. Most days my vapemail doesn't make it all the way in the door before I'm tearing it open, but you gotta play safely. It's just not worth it to chance your build.

Love that Emily. The voice of reason.

Em, Got donuts?

 

[emily n portland]

LOL

nope ...I do have some Ben & Jerry's Strawberry Cheesecake in the freezer,
but just enjoying some Refresh at the moment.

As a disclaimer, I wrap micro-coils which are very closely spaced (touching each other).

I wrap 30 gauge at 10 wraps around a 15 ga. nail which is a little bigger than a toothpick. That comes out to almost exactly 2 ohms. 28 gauge wire resistance is about 0.63 times that of 30 gauge. Therefore, if you were to wrap 10 wraps of 28 gauge on the same nail I use, your coil would be about 1.3 ohms. Since the toothpick you're considering is a smaller diameter, the wire length will be even less and the resistance will be lower. Probably around 1 ohm with 10 wraps.

Conclusion. Go find the guy that told you 5 wraps of 28 ga. to get 1.5 ohms and punch him in the face. Better yet, Give him your mod with a Trustfire battery and the same coil and tell him to try it out
