oxidize a wick for cobra atty ?

[healthylungs]

Could any one tell me how to oxidize steel mesh for cobra atty ?

I tried this myself on an AGA. You have to torch the wick until it goes black but I couldn't seem to lose the hotspots. So I have given up but I do believe that's how you oxidise it.

I dont oxidise mine at all,just a very light torching to 'clean' the mesh then roll as normal and fit.using a slightly discharged battery pulse the wick to mesh till all the coils glow even(bit of adjustment with pin can help it along) and fill.I find if I burn/oxidise the mesh that taste carries thru to the juice,using this method it is clean sterile? mesh bringing the juice up. Have read some use a rizla paper to help the burning in/ pulse between the coil and wick but not had to myself as yet


just set up a Kraken with twin coils with this method and blooming loving it, dont do it any other way now

Mesh has an unfortunate habit of leaving microscopic fibres along the edge under the wire unless you've cut it with sharp scissors which no matter how carefully you position the coils will cause a short. I've used a few methods to rid this problem, torching removes the traces of oils from the mesh but no need to blast furnace type burning. Wipe the mesh through cotton wool to create a fine bed under the coil, fold over the outside edge as you create the wick, or whilst torching look for the fine strands glowing red and gently wipe them with a screwdriver as you heat the mesh. This last isn't so efficient at getting rid of short circuit hassles though.

like chegs said folding the exposed edge of the mesh is important, new wicks even for the experienced rebuilder can be a pita, a few things that will help breaking a new wick in as was said folding the exposed edge of the mesh, dont make the wick too tight in the hole in to the tank as the hole edges scrap the mesh as it goes in causing earth problems, lastly slacken the center post screw holding the wire a little.
you can also put some juice on the wick before you coil it after you've oxydised the wick and light it, make sure you got a hold of it with some pliers!!!! this puts a protective layer over the wick. I also take the wick out when i recoil it and do a new burn with a torch, this cleans any juice remnants etc.
Most hot spots will dissapear if you wiggle the wick a little and the wick will settle down after a bit, but don't worry new wicks are tricky even for the best of us who've been doing it for years at least once the week is bedded in you wont need to redo it for the next millenium!.

Steel rope, with a bit of mesh around the top or a piece of ekowool , for me worked the best on my cobra clones.

Hold it in a flame on your gas cooker or youll need a blow torch.

Just torching with a gas burner works for me on the TD & AGI, Torch role then torch, the coil done via torch rap around a micro screwdriver that fit in the wick hole attach coil and slot in #SS it unravels slightly to fit whole never had shorts hot spots.

I prefer to use a microcoil in my Cobra .... a lot less drama

Yeah think micro coils are allot less drama in every build
