So I'm going to re-fit my Ego Vision Starwotsits (henceforth EVS, though I'm tempted to call them Alvins) at some point. I've got some decent wire (thanks Dee), but I'd like to know more about wick, so I'd appreciate any help.
The variables seem to be a) material and b) form factor
a) material The choices appear to be glass fibre and stainles steel, maybe kevlar fibre too.
I'm doubting if ss is suitable for the EVS because it seems to me that part of the function of its wick is to seal the inner chamber from the tank, and I fear that ss may not compress well enough to prevent juice leaks. Is that sensible?
Glass fibre seems to be standard, but if it gets too chopped up into dust it's quite nasty stuff I understand, and it's not that hardwearing. For a fumbler like myself this could be a problem.
Another possibility I've seen mentioned is kevlar. You can get this in clown shops for fire-eating wicks etc. What are its relative merits compared to glass fibre, anyone know? It looks cheap enough and it could also serve as body armour should I happen to enter a combat situation.
b) form factor I haven't measured the wick in my original EVS, but it looks to be somewhere between 1 and 2mm in diameter, also not sure if it's woven. My eyesight is imperfect. Is it the same as CE2 wick?
So if you could specify a perfect wick for Alvins, what would it be made of, what would it measure, and would it be woven or just strands? I'd appreciate any facts or opinions because I'm in the dark on this. Please be as techy as you like.
So how do I go about fashioning a ss wick, if I go for that? Roll it up? I suppose you need a certain gauge of mesh, but how much do you use per wick and how do you prepare it (I can do the oxidising bit I think)? Completely new to this stuff.
I only really want to shell out once for exactly the right stuff. Most of this seems to be sold in lifetime supply quantities.
its best to use stainless steel mesh #400 gauge take a thin wire and roll some ss mesh around it... you wont need much maybe 10mm square... roll it nice and tight and see if it fits down the slot... if not then reduce the amount of mesh
once you have the correct size hold it with tweezers and heat up with blow torch or lighter till red hot, then drop it in a tub of water. pull out and dry then repeat at least 4-5 times
take a length of wire and heat slightly with the lighter flame to make it a little more malleable so you get a nice tight coil... the coil must be as tight as you can get it
place in the AVS trying not to handle the ss mesh too much and scratch it
screw onto the battery and fire up to check that the coil glows red and none of the mesh does (if the mesh does then the oxidisation wasnt done correctly)... once you are happy reassemble
I'm in no rush either, but would like to try SS wicks, so I'd be happy to join a group buy if it helps. By the way I have seen another option on UKV in the context of the RDA, which is to wrap a SS wick round a fibre wick. Not sure if it would work in an EVS, but it looks like a promising approach.
