Bad, I watched a few videos on wick rolling and coil wrapping before I bought my RBA. I ended up combining what I felt was the best of them all. I am still using the the very first wick and coil that I made from the materials included with the AGA-T, and haven't yet touched the supplies I bought to go with it. The included SS mesh is not big enough to make a solid wick (and I I want to try that next) so I rolled it around a 1mm rod tightly, and was able to fit it into the 3/32" drill bit wrapped coil I made.
You can find plenty of vids on youtube, but here are the general methods I used:
(Four methods to battle top coil hot spots are "twisted lead", "L kink", "washers on post", and "bend wick to positive post". I will describe twisted lead method).
Coil:
1. 3/32" drill bit was largest that I had that would fit in wick hole, use largest you have available.
2. (Before placing bit in wick hole) Wrap wire around solid shank end using even, snug tension and keeping your loops very close together. (It is easier to spread them than to compress them later to fine tune the fit). If you are right handed wrap counter clockwise.
3. Take the drill bit off, meter the coil, reinsert drill bit (using even tension, add or remove coil to suit.)
4. Place drill bit with coil inside tank (I placed fluted cutting end in tank so I was working with the solid shank end, depends on how long your bit is, but don't let the coil sit on the cutting edge while working).
5. while holding drill bit steady, pull negative lead to opposite side of screw (should be coming off right side of bit to left side of screw) making an "S", wrapping back around next to the drill bit, tighten negative.
6. Take positive end coming off right side of bit, to left side of positive post making "S".
Here is where it takes practice or finness; Tightening the positive nut will pull everything tight. If it is too tight you will have problems getting your bit back out without stressing the wire.
7. Carefully tighten positive and with remaining wire, pass it over and under the lead between the bit and the positive post so it forms a twisted section (see pic in post 67) leading back to coil.
8. With the side of a needle and your thumb nail, make sure coil loops are even.
9. Remove drill bit and check resistance. Dry burn coil at about 8w and look for hot spot/ even glowing. If everything is ok, dry fire the coil 3-4 times to allow it to stiffen up.
Mesh:
1. If you use the included mesh roll a hollow wick, If you want to jump straight to a solid wick use a piece 3.5 - 4 inches long, depending on your actual coil diameter, and how tight you roll it. (It is easier to cut off a 1/4" if you find your wick too fat than it is to deal with your wick not being fat enough)
2. Roll mesh folding the back edge inward before you finish to eliminate possible shorted frays later.
3. Roll/roll/roll tighten tighten tighten.
4. Using my gas stove I do the three burn oxidation then coat with PG or VG and burn three times, then check with meter in various spots to ensure a high resistance.
5. When the wick is able to be placed inside the coil without difficulty (twisting motion helps) and will stay where ever you put it you are good.
Note: THE KEY TO HAVING NO HOT SPOTS ALONG THE LENGTH OF THE COIL IS HAVING THE COILS BARELY TOUCHING THE WICK.
This is why the drill bit method works so well over wrapping it directly on the wick. You are fitting a round rod into a circle, not wompiness into gobllygook (leaving varying spaced gaps all along the coiled wire)
6. If the wick is too big or too tight in the coil it will cause shorts/ hot spots and you will have a hard time removing and putting it back in without dinging your coils.
7. If the wick is too loose it can drop to the bottom of the tank and/or cause shorts due to the coil to wick gap.
8. Put your wick in all the way to the bottom and back it off 1-2mm.
9. Dry burn and check for even heating. A good coil will heat from the center coils first then out to the edge coils.
I have to keep my tank fill screw off to avoid vapor-lock.
If all done properly You will get plumes of vapor, no metallic taste, but very little flavor.
It takes a tank or two for the wick to break in and flavor to come through like a champ.
If you taste metal, you either have a wicking problem or a hot spot.
I did have to learn the "Genny tilt".
