The Tobie Coil

[Sir Pouncival]

I was messing around with some builds tonight. I did a bit of searching to see if someone else already came up with this build or not. I couldn't find anything so I'll see if anyone else here has stumbled across this build. If not, then I name it the Tobie coil.

In short, it's a coil within a coil using separate wires at different gauges (not the inception coil). The outside of the inner coil touches the inside of the outer coil. The effect is like having a huge gauge wire wrapped around small pin. I built one coil as a test and it read .6 ohms. It makes a good cloud.

Here are some pics of the build:

Cooling down


Wicked and ready to go


It's a 26 gauge coil (wrapped on 2.4mm) over a 28 gauge coil (wrapped on 1.62mm)

Very interesting! by just wicking through the coil it would seem the only juice getting to the outer coil would be the juice already getting boiled by the inner coil. sounds like it would b too hot a vape for my tastes

 

[Sir Pouncival]

I thought I would end up scorching the wick with that amount of heat but it didn't. I'm thinking of adding a wrap on the outer coil to see how that vapes.

 

[T4T3Z0R]

have you tried wicking it similar to the inception coil? ive never had good luck doing any sort of wicking that reqires wrapping cotton around the outside of the coil. my wicks always bur wile there is still plenty of juice in the wick. might be an interesting experiment though

 

[Sir Pouncival]

I'll give that a try and I'll post what works best for me tomorrow. I forgot to mention it was 12 wraps for the 28 gauge and 8 wraps for the 26 gauge. Both coils end up the same width so the leads run together into the posts.

Isn't that called a sleeper coil?

 

[Sir Pouncival]

No, it isn't a sleeper coil. That is one wire ran through the center pin and wrapped on each side.

Interesting coil setup. A possible experimental alteration might be to try wrapping the coil sets with more space in between. Then, add an additional layer of wicking to the mix. Of course fiddling with the gauges might be required as the outer coil would loose some of the heat up from the inner coil. The added problem would be wicking would have to be fast to transport juice as it would be shared between two coils, but if it worked, it should put out some vape as it doubles the surface area for the shared wicking. Just a thought... The coils are beyond my ability as you have that, at present.

I did find a good wicking method. Leave a small tail on the side, just enough to hit the bottom of the deck, then take the linger section and wrap around the outside of the large coil. Then tuck the small tail underneath at the bottom.

I tried building a dual coil using 15 wraps of 28 gauge and 12 wraps of 26 gauge. It came out to .4 ohms. I wicked it the same as above but it was too strong for my mech mod. I put my atty on my ZNA 50 and tried it at 25 watts. It takes about a second or two before it heats up but it give a decent vape. I think it's much better as a single coil setup.
