you may want to do some reading here on the forums before you go any farther with that mesh... I think I put a post with links to some pertinent threads in the monster mesh thread they are long but full of good info, or just do a search for 500 ss mesh and the one started by BJ43 (i think that's his name) will come up, its long as heck but very informative. Also do a search for calling all genisis pros, much shorter and has very good tips as well.
As far as your wick, do you have extra ss mesh? If not I wouldn't worry about it. When you are making your coil I would recommend trying to find a drill bit or jewelers screwdriver to wrap your coil around that is barely bigger than your SS mesh wick. Wrap the coil tight, then with the (in this instance) screwdriver still in the coil connect the wires to the neg post then tighten the wire and attach to the positive post. CHECK YOUR OHMS after you pull out the driver, find out what the resistance is minus the wick.
Pull the driver out and gently slide the wick in, it should go in with slight pressure, but if you have to force it its too tight, plus you will deform the coils. if the coil is tight then it will hold your wick steady. Push the wick till it touches the bottom.
Put your mod on its lowest setting, 3v is ideal, pulse the power button and look for any flares, that indicates a short using a toothpick, ever so slightly nudge it up or down then check your ohms, it should be at what the ohms were before you inserted the wick. Generally the place you will have the most shorts is the top coil, and right along the edge of the mesh, you can also get shorts where the wire is too tight on the mesh wick, it will also burn right through the wicks outer layer if too tight.
Keep nudging and after each nudge check your ohms or just pulse the power button to find each successive short till you get the coils all glowing evenly.
I dunno if this is what everyone else does but I do and it helps ME. drip 3-4 drops in the coil and wait a sec for the wick to absorb the juice. push the power button and blow on the coil area if you see a flare up you have a new short, nudge and do this again, and again and again. once you don't get shorts with juice and blowing you should be set, and your ohms should match what they were before you inserted the wick, if not you prolly have a short somewhere, but if it holds steady and coils are all glowing and it doesn't match the exact same ohm... just go with it and vape on it.
