"Nimbus"
well i gave it a shot and i guess it's ok, it Vapes!
28ga Kanthal, 9 wraps around a 30mm screwdriver @ 2.1 ohm's
resting comfortably on my SID...

my first coil...
 
sounds good man, i will build some more coils....tried building a dual coil but i kept getting "Low Load" and it wouldn't fire so i just tried a single....i'm getting good vape now... i'm learning so all advise is welcome.
....thanks
low load=low resistance, make two identical coils then divide total coil resistance by 4 for your new total resistance in dual coil configuration.

eg. two 4 ohm coils=8 ohms
divide by 4=2 ohms total

make sure your two coils are as close as possible in resistance or one will heat up more than the other
and it will taste like delicious burnt cotton

i just followed a video tutorial on the dual coil i made two 6 wrap coils they looked the same yet no fire, everything was tight...i have no idea on the math, just hoofin it...only started Vaping about 10 - 15 days ago.
probably think i'm a nut, maybe i am....but i'm gonna learn...

Well remember, take the average ohms of the coils and divide it by the number of coils you are making. For example, if i had a 3.6 ohm coil, and a 3.4 ohm coil, you would take the average of the two, which would be 3.5. Then you divide that by 2 since you have 2 coils, and the total ohm would actually be 1.75.

Tips:
-the more wraps you make, the higher the resistance, which means the higher the ohm reading is going to be. For example if i have wrapped a 28 gauge wire 5 times it would be about .8 ohms (depending on what you wrap it around), if i had wrapped it 10 times it would double the resistance, becoming 1.6 ohms.

-When you finish building a coil, and after you connect it to the posts of your rda, you should hold the fire button till the coil gets glowing red (hold it till its glowing red for about 4-5 seconds) then let go of the firing button and as fast as you can use tweezers to squeeze the coils as tight as possible, repeat until satisfied. You want to make sure it glows red from the inside out, once you have that, its perfect.

-You might already know this but, you when you put your cap back on, make sure your air holes are directly infront of the coil for more airflow. The more airflow the more the coil will heat, again, more heat, more vapor/flavor. Now when it comes to air hole sizes everyone has there preferences. Know that the bigger the airhole, the more airflow going to the coil. When you drill your air holes always start small and work your way up, you dont want to drill a big hole, because you cant fix that.

Thats all the tips i can think of at the moment, if you have any more questions ill be glad to help.

@ Jayyco, great man....i did follow the last 2 tips you posted...now i understand why i got the low Load signal....need to make the coils bigger.....so i'll make 2 of the same in another 9 wrap or more but have the wraps closer together?
my Nimbus has 2 holes already, don't think i want more...

i gottcha...i rested my screwdriver inside the coil wrap along the edge of the coil base while attaching to make them even and uniform and not touching anything...and squeeze adjusted for size uniformity

gonna experiment with some diff coil sizes tomorro, i'll get it...

When experimenting try the same 9 wraps touching each other as jayyco said earlier.

Also you may already know this but just in case you're like me you won't feel super stupid afterwards. On my first rebuildable dripper I didn't know that the airhole needs to be as close to the coil as possible. I had been building genesis style atomizers forever so I knew the coils were good. I probably rebuilt the coils 10 times before I had the lightbulb spark that moving the airhole next to the coil makes it vape perfect.

figured that out quickly, all i was getting was flavor and not much vapor...remembered watching on a video where the dude said that...and the lite came on and i started playing with the cap and ShaZam i hit the spot....nice Ploooomige of Vape...i lucked out once again :vapor:

this Nimbus is burning juice by the Gallon already, can't imagine how much with 2 coils, might just stay with one for now...since i'm a green Newb i prob should keep it simple for awhile and learn basic things first...i will get there in time!

Congrats on the first coil. I just built my first successful coil tonight (had a couple bad ones and gave up last week). 6 wraps of 32 awg kanthal on a 5/64 drill bit and pulled tight. Finally got the coils pretty evenly spaced. Came out to 2.6 ohms, which was higher than I expected. Dry fired it and the center lit right up, then spread all the way out to both ends symmetrically. That sure looked a lot prettier than the other ones! Seems to vape ok, but I think I need to drill out the airhole on the cheapo RDA I put it in.
