Just got my AGA T2 in today, new to wrapping coils (myself). There's seems to be only one area that gets red hot, then pop. Why is it doing that?
Need help! Coil burning up!

Ahhh... the dreaded hot leg! The most common reason is that the top coil is putting too much pressure on the wick. This happens when you attach the wire to the positive post... You tighten the positive post and as you turn the nut, it "drags" the wire with it adding tension to the top coil, making it dig into the wick.
HTH,
Jason
There are a few ways...
1) Do a Google or YouTube search for the "PetarK" method or building coils. Basically you build and install the coil separate from the wick. The wick is installed after the coil is in place. There are lots of "how-to" videos on this. (My personal, preferred method)
2) Add a small washer under the top nut. The wire goes under the washer and prevents the top nut from dragging it.
3) Leave a loose top coil. Let the tightening of the nut drag the top coil into place.
Just remember there should be NO actual tension between the wick and the positive post (or negative screw for that matter). The coil should simply lay over the wick without gripping it or digging into it.

yes the washer works great, also you can eleviate the tension by slightly tightening down the top nut, then finish the good connection by tightening up the second nut. use both nuts to achieve a good connection
I use a safety pin & tighten the lower nut into the top one (while keeping the top one stationary)with no washers. It doesn't pull the wick into the post.
This...Also, you need to repeat the above process very carefully once you gone through your pulse/coil poking as the heat loosens the nuts.
This hot leg was too common not to have a simple solution. Once I made sure everything was done right, I went extra carefull on the centre post connection. Those AGA nuts are a pain to grab and tighten and the coil gets easily pulled. Counter the pull of the top nut by tightening the one under the leg of the coil.
This happens on my DID also. Surely by now, someone has found the correct size washer on Amazon or some other hardware site. The AC9 has a spring, with washers, between the nuts on the pos post. This makes it really easy to slip the wire between the washer and nut and not have to mess with trying to tighten it. But (as I just found out) I also have to make sure I've got the correct tension when I put that wire there. I'm looking for a spring to experiment with this on the DID. Springs out of ink pens look a bit large.
I remember when a bunch of us were modding carto tanks.. we were able to find all the tubing and grommets and screws on amazon.

lol just ordered a box full of 1 and 4 oz bottles off amazon for DIY. i love that place.
From my reading, the correct washer is an M3. My local Home Depot and Lowes don't have them but I've seen that Ace Hardware should but I don't really have one I can get to easily so I can't verify that.
I started using spring and washer, when I was playing with bubble stone wicks, that top nut system is a real stone breaker. Anyway, I didn't want to hassle with getting a washer, so I took one from a vivi nova head (the metal washer that sits in the silicone cap on top of the atomizer). Works good upside down. Also captures the spring. Here, lookie . . .

Practice practice practice. Until you get the feel of how tight the coil should be.
And as mentioned, the drillbit method seems to help. Lot of folk with the top coil hot spot. You still would have to roll a great wick though. Because it s Ulster have enough tension on coils to grip the wick, but not so much as to let the wick just fall right through. If you are new to it, give it some time and a lot more coils. Took me weeks to get fairly consistent and I still get a hot spot at the top coil every so often.
Also, make sure your wick is trimmed up around the edges. When I started doing ss mesh wicks, the tiniest little frayed strands were causing shorts on me.
Some time and practice along with some of the suggestions from this thread and you'll get it. Good luck bro.
