i have now used SS mesh wick (400) on all my Novas and A7 rebuildables and a rebuildable Smoketech tank from AltSmoke and it's dead easy to make. All i do with it is cut a small strip, say, 2.5" long for a Nova or about 1.5" for and A7 - and just roll it in your fingers like folding a cigarette paper.
I find it unnecessary to roll the mesh around anything and you can make it smaller and tighter - to fit thru holes or in slots - by just rolling it some more in your fingers - from the center and working out to the ends. I can make a mesh wick in this fashion in about 2 minutes flat. It's a lot easier than repeat boiling cotton etc and being SS - it is durable.
I am awful at making coils, but using SS mesh and holding the wire tight and close to where you are doing the next turn makes it easier and the stiffness from SS mesh makes it possible to do without needing drill bits etc! The drill bit method btw is from Peter K - so Google that to see his method.
In my experience it's wise to oxidise the mesh and repeat quench it a few times in water with a blowtorch or a cigarette lighter to reduce short-circuits. Also - once you have your coil on it the way you like - heat that then too - because that sets the shape and you can then fit the mesh and coil to whatever you wish.
The longevity of the mesh is good - i have one Nova here attached to a Silver Bullet, that i have been smoking daily for over a month now. Every 2 tanks or so - i just rinse the whole thing under a tap and it's as good as new.
I apologise for this being perhaps too long - but i hope some of it is useful to you.
