Okay, let's preface this with two things. 1. I'm pretty good at rebuilding coils. I've done a bunch of heads that are all in the 1.1 to 1.7 ohm range, no shorts, all on .5x.1 ribbon. 2. I suck at wicking. Really. All my wicks either flood because they are too loose or burn because they are too tight. ALL OF THEM. Drives me nuts. Granted most people would say that isn't a long drive cause I live in walking distance to crazy, but that's neither here nor there.

So I'm looking at YouTube videos for some kind of hint to what I'm doing wrong, when my eye catches a vertical coil tutorial video and, as per usual, I get distracted. I watch and figure, doesn't look to difficult, why not?

I use a small nail to wrap my coils. The type you would usually use to hang a picture on the wall. It's a prefect fit through the grommet and little metal stopper thingy that goes in the grommet. After pulling the coil out of the base I put the grommet back in then put the nail in it, flat end first testing on top of the grommet to measure how much coil I can wrap without going too tall.

After getting a good idea of the coil width it's not very different than any other ribbon coil build. I leave the legs perpendicular to the coil, take it off the nail to torch, put it back on, then bend one leg parallel to the coil. I then wrap a few layers of cotton around the coil, bend the other leg down over the cotton then continue wrapping cotton around it, making sure to not cover the top of the coil. You want that totally open or there's no airflow at all.

Make sure your legs are on pair sides of the coil to prevent any shorts.

Losing it in the base is actually easier than horizontal builds. You leave it on the nail, drill bit, rod or whatever you choose to build on. It will keep your coil centered and the grommet and stopper thingy fit over the nail. Make sure it isn't too tall in the base where it will touch the chimney and short.

The cotton should touch the sides, but do not need to come out into the tank. Mine do not and I get great for to the coil and haven't leaked yet. Wet your wick before replacing the chimney, but not too much. I did this and it gurgled like crazy at first. After a bit the juice burned off and now all is golden.

I'll post pics when this bit of laziness subsides and I build another. The flavor is the best I've had so far. I'm running at 12 watts on a 1.5 build and haven't had a dry or burnt hit yet.

Thanks for reading, all. Pics should be up within a day. Be warned though, they will be sucky phone cam pics.

Lol, yeah, I think the time and commitment to do this as a business are assets I do not possess. It isn't hard at all, though. Give it a go. The supplies are relatively cheap, about what you would've paid for a couple packs of the stinky sticks. The amount that that you get leaves you lots of room for trial and error. And like I said, I suck at wicking, but this is wrapped around the coil rather than pulled through, and seems to wick well.
