Ok today I’ve got a quick and dirty one showing you how I like to coil up a Nimbus for use on a DNA 30 device.
Over the past couple months, I have been really into variable wattage, with the DNA20, DNA30 and OKR T/10 devices like the Duke. When you’re running at super high wattage, the easiest way to keep a consistent and clean vape is with a dripper. I have had some tank builds that I run at pretty high wattage, but you can never go wrong with a dripper because you can always make sure your wick is saturated enough so you avoid any nasty dry burns or harsh hits.
Coiling up a RDA for a high wattage situation is very similar to how you would normally do it. The primary difference is, I like to run my ohms a little higher. Normally on a mech, I wouldn’t vape any dripper over 1 ohm at all, but on a high wattage device, I like to run them between 1.5 and 2 ohms.
So let’s get down to business.
What You Need:
- A rebuildable atomizer. For this tutorial I am using the Foggy Nimbus
- A 1/16th drill bit. I just picked up a 10 pack of titanium ones at Menards for about $3.
- A cotton ball – I recommend sterile or organic
- 28 gauge kanthal – I get mine from Temco on eBay.
- Something to trim your wires – I like a nail clipper best
Step 1: Wrapping the Coil
This is really fairly straightforward. What we want to do is wrap a nice, tight microcoil. If you don’t know how to do this, go here.
For this build I did 10 wraps of 28 gauge kanthal on a 1/16 drill bit.
If you are using a Nimbus clone, you are going to want to cut the legs pretty short, as it will make it a lot easier to thread.
Once your coil is wrapped, go ahead and thread them through the posts. I always leave the drill bit through the coil while I am doing this to keep it straight and uniform. I like to try to get my coil about 1/2 inch away from the posts so that it is close, but not in any danger of actually coming in contact with either post.
Once your coil is attached, CHECK YOUR OHMS. You should always do this before firing the device.
If your ohms look OK, dry fire the device until the coils glow bright orange. Then take a pliers and carefully compress the coils and hold them there for a few seconds. This should leave you with a near perfect microcoil.
It should look something like this:
Once my coil was compressed to this state, it clocked in at a perfect 1.5 ohms – just about where I wanted to see it.
Step 2: Apply the Wick
Again, this is about as straightforward as it gets. You’re going to want to tear off a small chunk of cotton. When I say small, I really mean small. I’m thinking roughly about 1/32 of a cotton ball. Make sure when you pull the cotton off the cotton ball, you try to follow the grain.
Roll half of it into a fine point that you can thread through the coil and leave the other half as-is.
Thread the wick through the coil carefully – make sure not to force it. Once the wick gets too wide to go through any further, gently roll the wide end with your index finger and thumb and carefully pull on the thin end.
I like my wick to be a slight bit loose inside the coil.
Once you have it in there good, trim off most of the excess. I usually remove almost the entire small end, and leave about 1/2 inch on the long end.
When you’re done it should look something like this:
Notice that I really do not have much cotton there at all.
At this point, prime the wick really good so that there are no dry areas, and you should be good to go.
I run this at 30 watts with no problems at all, and it also performs good at 20 watts if you don’t have a device that goes any higher.
You can take a look at the results here:
- I really prefer using a very small amount of cotton on a build like this. One important thing to keep in mind, however, is that you will have to drip a little more often.
- My Foggy Nimbus has a single airhole drilled to 1/16th. You can go larger for increased vapor production or smaller for a tigher draw and harder hit. My sweet spot is 1/16.
The Bottom Line
There’s really nothing terribly special about this build other than it is quick, easy and performs brilliantly. The small amount of cotton through the wick, in my opinion, is an ideal setup for optimal flavor while still maintaining a great quality of throat hit and vapor.
Have fun and be sure to check your ohms.
