    Mesh & Kanthal Options - What's the difference?

    Hi guys,

    I've got some Cobra clones that i need to get some mesh and Kanthal for to try rebuild.

    Can someone please explain what the difference is between 28, 30 and 32 gauge kanthal? Also the difference between #325, #400 and #500 mesh? In what ways do these affect the outcome?

    Also for a phoenix RBA does that just need 1mm silica wick?

    Thanks in advance!

    Kanthal. The lower the number the thicker the wire and the less resistance. Eg 28ga kanthal has less resistance than 32 for the same length.

    Mesh 325 is think is 325 holes in it per square inch. and 500 is 500 holes per inch. (Dunno if its inch for sure or whatever). The holes in the 500 mesh are smaller than the holes in the 200. I think bigger holes is better for thicker juice I found but some may not agree.

    Phoenix. No Idea dont have one.

    There should be a thread here somewhere mate?

    Umm basically the lower the number the thicker the wire,the thinner the wire the more resistance just like a water hose or an exhaust pipe would do to the flow.Thinner creates more friction(heat) for lesser length.

    The mesh # is how dense the mesh is as in strands per area(not sure of the exact measurements), so lower will be a looser mesh.This is a choice depending on the viscosity of the ejuice and the size of the mesh before you roll it plus the thickness of the finished wick.
    Basically lower is used for higher VG as it will stick better and wick.

    The mini RBA will need 1mm yes, I've tried 2mm and just squeezed it in but mine's got a faulty connection so didn't get to really used it much.

    I'm sure someone will have a better explanation but should give you an idea mate.

    Good luck with it Domo

    Edit:There ya go Ol arth got in first mate

    Like Mush and Arth said - I made up a table to help pick what gauge of wire gives what resistance for a given length: Wire design guide

    Mighty kind of ya Mathsguy

    Mate, is the Nichrome the same as Nichrothal?

    Kudos!

    Should have a sticky for all these things for RBA's.

    I can't find the SteveVapes google Doc spreadsheet link for selecting the sizes to cut the mesh for each atty atm.

    Someone got it handy?

    I guess it depends on the exact alloy, but wouldn’t be a hell of a lot different - the figures I got all came from the Kanthal company, but if you got others I can easily chuck them in (just need the resistivity).

    Apparently there's 2 grades of Nichrome but this link might help?

    Cheers Mush,

    OK Just did some checking, and I also found rho = 1.08 (www.alloywire.com) and 1.09 (www.niwire.com) so you should be good to use the Nichrothal 80 table. It looks like industry expect it to be pretty similar whoever makes it.

    Cheers mathsdude

    Just need to find that Steve k/Stevevapes Google Doc spreadsheet for selecting the mesh for your atty....pretty sure I can find it or I know that yatesy has the link.I have posted it before in an AGA thread somewhere also.

    Should sticky all this info as people move on to these atty's.







    Anyhow photo-3087.jpg.....ahh make it a few hours,way past beer O'Clock

    In toying with dual wicking I learnt that I could make two wicks out of the same piece of mesh. Cut exactly the same size, rolled, and oxidised with the same routine, and have one that wicked really well, and one that really didn't!
    I'm using #200 mesh with #28 Kanthal, and it's working really well, but I've also had #400 mesh with #32 Nichrome that worked really well too.
    Seems Kanthal is preferred for SS wicks.
