My coils do not heat in sync!

[Mr Moustache]

Let me start off by saying I am finally diving into the world of RDAs!! I purchased a TOBH Atty V2.5 as well as a 454 Big Block. My device is my newly aquired Vamo V5 (finally arrive from fast tech after 3 weeks!)

When I am building a coil I use this cool little online tool, Coil Toy - Online calculator for e-cigarette resistance coil building

The Vamo also will not fire any device rated under 1.2 ohm so I am limited with how low I can go.

All I have is 28 guage kanthal, I have an ohm reader, a torch, coiling gizmo, and the other needed supplies.

i experimented with a few different sized coils at first, 3mm (the coil gizmo does not have a 2mm unfortunately.) and that was much too large and took a long time to heat up. 1.5 mm, I believe it was with a crazy amount of 22 wraps each! Obviously took time to heat and they did not heat up in sync. I then used the tiny screw driver provided with the RDAS which I believe to be close to 2mm, about 18 wraps each and it works OK but still am having the issue of them not firing at the same time!!

After I built the coils I tested them on the meter, then proceeded to fire them on the device, pinch them with tweezers, and adjust them. Nothing I did would fix the problem of one firing up late however!! I can not figure it out!!

I would really ally appreciate it if I could get some suggestions. Keep in mind all I have ATM is 28 guage kanthal. How should I do this build on the TOBH Atty V 2.5.

Thanks a a ton and vape on!

the one that fires up slower... insert your screwdriver back into it & undo one of the post screws that is holding it in place, you need to make this coil a little shorter on the length of wire it has so you could move the coil slightly towards the posts to shorten a leg and re tighten the post screw back up and test.

it doesnt matter if your coil leg's are uneven


Next time you wrap two coils you could cut two lengths of wire the same length and then make them GL

also make sure your post screws are all tightened nice and snug, if one is a little looser it will fire slower

You will want to ensure that both coils are tightly secured to their positive/negative posts. Remove the hot legs by running a smaller diamater drill bit or or rod through the coil after pulsing it. If you made 5/64 ID coils, after pulsing, slide a 1/16 drill bit or rod through the coils while applying some tension/pressure to the both sides of the coil, pull away slightly and then pull towards the positive post with just a little pressure while sliding.

Your hot legs will be gone and both coils will fire at the same time. It is important to note that while doing the above method, before checking that both coils glow evenly to just blow on them. The one you were sliding the rod through last will be hotter then the other and will continue to heat up slightly faster.

If that doesn't do the trick, then you need to post pics of your build and make sure none of your coil legs are scrunched or overlapping. Ugly coils never work as well as the pretty ones.

hi tmel i think you have it the wrong way around with the last one you slide your rod through being the one that heats up slightly before the other on the first fire up after a rodding

 

[tmel]

yeah, I got mixed up

 

[Mr Moustache]

Thanks for the info everyone! I shortened one leg and that helped. I appreciate all the tips, I will remember them for next time.

 

[Mr Moustache]

Now I need to figure out why they take so long to heat up! My Vamo will not fire anything less than 1.2 ohms so that makes it so I must wrap 18 times!!! It is a ton which I know will add to the time it takes to heat but there has to be a better way. I wrap around the little screwdriver that comes with the RDA which is about 2 mm using 28 guage kanthal.

Any tips will be appreciated.

Why not just do a single coil at 1.5 ohm 28 gauge.

Because you've got a Vamo, not a mech, you're gonna need to go higher voltage to compensate for that. Not a bad thing, you can still achieve a great, cloud producing vape, you've just gotta kick it up a notch. Adjusting the ohms on the coil is how we compensate for a mech's lack of adjustment. You're regulated, so hit it with higher and higher voltage until its heating like you want it to. If you're getting burnt taste at higher voltage, try dual wicking it. Bend the coil at the half way mark and run two wicks for that coil pair. Most importantly have fun! Rebuilding can be both rewarding and extremely amusing if you let it.

I don't think a Vamo is going to push enough watts to do dual coils at that high resistance. Stick with single coil, or get a better mod.

Well to be honest, I need a "vaping for dummies" book because even the simplest things go over my head. I honestly was unsure if it could be used with only a single coil. Even then, would the vapor lack due to only one heat source?

I actually do vape with it maxed out, I find it set at 15 watts proves for a slightly faster heat up time. I do not get any burnt taste but will look into dual wicking to see the pros to it anyways. And even though I am having trouble at times building is very fun.

A mec mod is next on my list, unfortunately I'm maxed out on funds for a while. I bought the vamo, 2 tobh attys (one for a friend as a gift), and a 454 big block atty. Now, I'm out of juice and am smoking my tobacco stock with no funds for anything!!

 

[Israfil]

Aww....thats sucky. If its still not hitting at full power then I'd say drop down to one coil for now. Save those coils you made for later. Definitely keep your juice stock a little more full.. If you don't have juice than there's nothing to vape no matter how cool your build/mod.

Also, really nice of ya to buy your friend a Tobh when you're so low on funds. you are a good moustache.

Heat n sync???

Yes of course you can use single coil.

No, the vapor won't lack.

So today I went ahead and shortened up the legs to both as much as possible without the coils touching the posts. It dropped the ohms by .1 to 1.3 and they seem to heat up a tad faster as well as at the same time. When it comes time to rebuild new coils I will try out a single coil build and see how it works out.

Yes I do need to keep my juice stock up. But it is what it is, I miss my pipes anyways! LOL!

And as for me getting him the atty, he has done a lot of work on my truck for free and he is trying to stop smoking sticks so I figured what the hay and since I was getting myself one I thought what's one more LMAO!
