Pull the wick out and torch the wick again.

xplumber, mine looks exactly like yours, i snugged it up so i had as little kanthal as possible between the post and the coil, still nothing, havent tried wrapping method, but doesnt really seem like a short to the wick...
Agreed, also notice how the coil in that pic follows the wicks contour until it hits the center post. Keep as much of your top coil touching the wick.
scott, (I swear no sarcasm) thats what causes it? I always thought that lack of liquid was the reason for hot spots. i may have to try the rolling paper trick ive been using the drill bit method
The rolling paper method is great to make sure that you've oxidized the wick enough. Make sure that the wire coming from the top of the wick to the center post is almost parallel or a wee bit higher and gently attach it to the post. I have a habit of really pulling it tight and tightening the screws around the wire which caused hot spots for me. Also try counterclockwise around the bottom screw, clockwise around the wick and counter clockwise around center post.
I cut my coil wire leaving about 3/4 of an inch extra on the ends. I make my coil, then fold and twist the extra around the wire until it's right up to the beginning of my coil; cut the excess off.
I have tried the drill bit method, but the coils are never touching the wick enough so I get less vapor and more heat.
jazzy, are you saying you twist the extra on the wire from the wick to the top post? I like that idea if so
scott, ill try and grab some papers tomorrow night (will have a new juice order in, dont want to waste anymore) and give that a shot again. Thanks for being helpful guys, ill let you know how i make out! I just really want to fall in love with the rebuildables, im such a tinkerer and this turns vaping into more of a hobby!

Not from the wick; I'm essentially doubling the size of the wire making less resistance than the rest of the coil. You could use NR wire to do this, but I find it easier to just fold the ends back towards the coil wrapping it as I go. However, having larger washers would probably be the best option. I haven't tried that yet. you can also just make your wrap around the top post, then twist the extra around the wire back toward the coil...

I found that over-tightening of the screws causes hotspots sometimes. It took a few times to get it right.
I use the "double back" method also, especially on the AGA-T, where the distance from the wick to the center post is fairly wide, compared to some of the other types. Alternately, Ace hardware has a good selection of small stainless washers, which can be installed under the top nut of the center post.
Ah, Ace Hardware! Thanks for the reminder
I like my AGAs. "double back" is a great way to describe the method. Noted.

Ace is good for washers, replacement fill and ground screws, o rings, etc.
I need some clarification here as it seems that some are talking about the top coil being excessively heated and others are talking about the short section of wire that goes from the wick/coil to the center post, I am getting confused here, maybe others are also.
By the way ,I just added two small washers to the center post.
