This thread is long overdue, but it's better late than never. I hope Nach doesn't mind me starting this up since this build is essentially his Ophion coil, but I think that people are getting a bit antsy to get their Stratas performing optimally. The coil that I make varies slightly from Nach's, but it is relatively simple to make. It is essentially identical to building a microcoil. I am using 26g kanthal, 7 wraps around a thick paper clip (measuring 0.035" in diameter). I torched the coil after wrapping.
Once the coil has cooled, stretch it out a bit and then attach it to the positive post. Do not stretch it out too much at first because you want the length of the coil to fit perfectly around the periphery, and it is easier to stretch the coil further rather than to compress it.
Once you have the coil attached to the positive post, slowly stretch the coil out to the proper length and attach it to the ground post.
Here is the coil lit up:
Pack the center with your wicking material of choice; I use organic cotton wick. I have been getting better performance from loosely packed wick versus a tightly packed wick. I have not been stuffing the wick all the way down to the base because I like it to act as a reservoir for juice. The height of the wick should not pass the base of the helix portion of the positive post.
Now fill it up with juice, let it soak, and vape away!!!
