I like the idea of an Optimum Glow! LOL
Thanks guys! Sorry, we've been at softball games all day! Here's 2 pics. I took the cap off and fired it and it didn't do it at all! Could it be I need to make my air hole larger on my rm2?

If you are running with the stock intake then 0.6 ohms is a bit to hot. Also, the left " leg loop" has too much of a gap and I'm sure you are getting a hot leg on that side. As suggested before, pinch the coil in to where all the coils meet. Your air gap is perfect and the wicking looks to be O.K. Here's a quick pic on how I set up my RM2's with a twisted coil.. As always, I hope this helps. 
Thanks distortoblotto! Do you have 8 wraps of 28 twisted? I'm new to the twisting, and I'm not very good at getting my coils just right!If you are running with the stock intake then 0.6 ohms is a bit to hot.

Indeed, it's a twisted 28 9/8 wrap built to 0.7 ohms...
Steam Engine... Coil wrapping | Steam Engine | free vaping calculators is your friend...

More wraps =higher ohms or is it the other way around? That coil wrapping calculator never works for me..why is that?
As a general rule yes, but then other factors such as gauge of the wire, size of the coil, round,ribbon, Ni200 or Kanthal and whether it is twisted or not also come into play...
Confused yet?
Um...yeah! Always!! Ok...I'm usually going to use Kanthal, 27,28 or 29 gauge, round, either on a 16 gauge needle, 2 mm screwdriver or a 5/64 drill bit.As a general rule yes, but then other factors such as gauge of the wire, size of the coil, round,ribbon, Ni200 or Kanthal and whether it is twisted or not also come into play...

When I build another twisted coil for the rm2, I'll just look at the one I'm taking out because I don't remember what gauge Kanthal I used to twist and I still have some. Lol
For ohms, my preference is in the 1.2-1.3 range, what I'm wrapping on depends on what I'm putting it in. I'm really getting into the GS Air line(Airs, M's and MS's) and I rebuild those coils on a 16 gauge needle. The 2mm ones are a bit big for those. I use 2mm for the Lemo Drop, the SubTank and my baby.
A 16 gauge needle comes out to 1.29mm ( for all intents and purposes we'll round it off to 1.3. With that being said and using a baseline of 1.2 ohms with round wire your builds will be as follows...
27g = a 13/12 wrap
28g = a 11/10
29g = a 9/8
Bumping up to 2mm...
27g = a 10/9
28g = a 8/7
29g= a 6/5
By sticking to these guidelines, you will be right in the ballpark every time. The only variance to this is the length of the coil legs. All of the above are based on a total leg length of 5mm. Shorter legs will drop the resistance a bit as will longer raise it a bit.
The longer you build the more things come natural to you and you will eventually come to a point where you will be able to wrap most of your favorites right off the top of your head. Even so and as you well know, always check all builds on an ohm reader just to make sure...
I know you have some experience under your belt and I did not only post this for you but also for others to benefit from as well...

Thanks!!! You're my hero!!
One more question and this is in the steam engine thing...coil leg length...how do you determine that? What does that mean?

Coil leg length has to do with the power loss to the coil as well as the heat up time of the coil. It is also the distance between the anchoring block to the coil itself.
For example: A 28g 2mm coil with a total leg length of 5mm would result in a 7.5 % power loss to the coil as to where the exact same coil with 3mm legs would result in a power loss of 4.5 %.
Another way to compensate for the power loss would be to build to slightly lower ohms. In most cases though ( except for in the case of very long legs) the noticeable power loss is negligible. The one case I simply could not stand was with the Lemo and is the reason why I crap canned the concept with those and simply went with the Kayfun style of coiling them right away.

So what you're saying basically is the shorter the distance from the coil itself to the point that it's screwed in or whatever would result in less power loss?
And why, pray tell, would you think that I thought you posted these bits of info only for me?
Yes! And the reason why I posted about " info for others as well" comes from many years of training new apprentice engineers. I always try not to become overly technical and explain things in the simplest terms because in the past I've had people that are already in the know look at me or say things like " What! Do you think I am stupid or something? " It's merely a now built in defense as I never wish to insult anyone tis all...

You could never insult me! I'm always learning! And still need help too! Thanks!!
Well, I didn't think that I did but still, I always cover my bases...
The reason I asked in the first place is I can never recreate a build. I may build a coil and it comes in at 1.2 ohm's. Next build is wrapped on the same thing, same gauge Kanthal, same number of wraps but I get different ohms. I can't figure out what I'm doing wrong.
