The Dragon build, anyone use it? BUILD PICS

[robby]

Does anyone use the dragon build? At least I think it`s the dragon build lol. It mainly consists of having the cotton wick on the outside of the coil. The pic is my first attempt yesterday. It`s Titanium, 8 or 9 wraps in microcoil fashion but mine is 3mm diameter coming in at about .45 ohms (.5mm wire). The choice of wire type is not important but I wanted TC with a resistance that I could use in most TC mods. It`s a totally vertical coil which is well suited to the Magma with it`s excellent airflow design. 

The coil is centered directly above the airhole inside the dripper about 2mm or so above it. After a lot of farting around and experimentation it is working really well in the Magma dripper, forces out vapor like a steam engine. The coil leg design needs improvement to make covering the coil completely easier and quicker, that`s the next step. Could also have two coils in the Magma, not sure I`ll need two though at my usual wattage.

I havent played with my Magma for ages. I'll give this a whirl.

Built another one with pics. 9 or 10 turns of .5mm Titanium at 3mm diameter. Having thought about it a bit, it really doesn`t need to be a close coil. Slightly spaced will probably work better and lead to better liquid feed to the coil. Time will tell. Resistance is about .45 ohms.

The coil was wrapped on a 3mm diameter former. I used a 2.5 mm to centralise the coil over the air hole, it turned out to be a perfect fit for the airhole and kept the coil steady and in position.

You are going to be wrapping the wick around the outside of the coil and to get the best coverage and easiest build you need to bend the coil end wires as shown, otherwise you will probably end up with hot spots on the coil. In this pic see how the bottom wire is bent.

The same needs to be done with the top coil wire to allow for maximum wick freedom.

Cut a bit of Muji slightly wider than the height of the coil, you want to totally cover the outside of the coil with the cotton strip to avoid hotspots.

Feed the wick between the positive post and the coil, covering the length of the coil. Try and judge it so that when the rest of the wicking is done that they have equal lengths.

The other end of the wick then needs to be slid between the coil and the negative post. TRY AND MAKE SURE THE NEGATIVE CONNECTION TO THE COIL IS THE BOTTOM WIRE. Then if the bottom of the coil touches the atomiser, it wont be an issue as it is negative anyway. If you do it the other way round you could have a short.

The completed Dragon, vaping very well. The critical thing for liquid flow is to make sure that the wick where it goes between the posts is not too tight. If it is, remove a bit of cotton from that point of wick contact. Where the wick wraps around the coil, you dont want it too flat, but you dont want it too slack either. Somewhere between the two is ideal.




This is just the second time I have built this so probably room for improvement with different wire etc. I am vaping it on the RX200 and it is working very well on the Nickel TC setting with the temp at 360F.

I run my crius tank like that, with one .4mm 316l coil at .44 ohms vertical at 10w.
Get great flavour ,great battery life out of my vtc mini and it don,t eat the juice.
Coil is 7 raps round a 2mm drill. The cotton blocks off one air hole and uses the four
juice wells, never a dry hit and no leaks.

Not tried it on my magma as I only use it to test juices and the standard way of wicking is quicker for that.

What attracted me was that the coil is totally vertical and directly above one of the airflow holes, really works well and in my opinion better than the other option of the the wick through the middle of the coil. Going around the coil there is much more metal to wick contact and much more juice available immediately. Loving it so far on TC I am a comfirmed dripperaholic lol. tanks just dont give me the flavour I want and more vapour production this way.
