Eh... Seriously?? my 29awg Kanthal A just arrived in the mail today... Nothing but praises for #500 mesh + Large surface area 6/6 coils.

Interesting from Boden:
BIG discovery!!! The resistance difference between the 36awg and the SS Wick is not high enough. The 32 should work better and if you can get enough coils with the 28awg it should be even better.

I have read it ....in practice I got it already as my 28 AWG setups are so much better then 32 AWG 
I posted this on the other thread.
Forget all that about how many coils and back to basics, what Boden is saying is that the closer you get with the resistance of the wire (not the coil) to the resistance of the SS the more likely the current will transfer to the ss wick and short. He is not referring to any length or wraps just a physical point.
Quote Boden.
edit2: As long as the Watts stays the same the electrons will stay in the lower resistance wire better than the higher resistance wire.
The oxidzed SS wick has a high resistance but the thinner the wire you use (higher resistance) you start closing the spread between the two and make a possible short easier.
I repeat this has nothing to do with if it is a 1 ohm coil or a 3 ohm coil. It has to do with the resistance of the wire at the point it is next to the SS wick, a high resistance wire like a 38g will short easier than a low resistance wire like a 28g. It is direct relationship between two unequal resistances, the wire and the oxidized SS wick, has nothing to do with how many wraps or ohms the coil is. The higher the difference at any given point, the less likely a short.
A 1.6 ohm 36g coil will short easier than a 1.6 ohm 28g coil on the same oxidized SS wick.

Excellent point, BJ43..... reminds me of the old rule..... "the path of least resistance"...... electrons will take the fastest way to ground they "see". So as long as that wick is properly oxidized, everything will be dandy. The electrons will just happily go round and round that coil back to the battery....(so to speak).
Thanks for making that much more understandable, BJ......

I only have the Kanthal D. I'm in search for the A-1 at 28. I wrapped a 5/4 coil with the Kanthal 28 type D and got 1.8 ohm LOL

i got my mesh and i have no idea what the numbers say lol. one is 500 and i think the other is 200 but i cant tell which one is which. would the 500 be more see through or grayer if that makes sense.
Less see through, put it up to a light and less light thru the 500
Thanks for re-stating 'it' BJ. I had to read what was posted a couple-few times. At first I thought he was trying to say the higher 'g' / lower resistance wires tended to 'ignore' the oxidation layer and short with the SS mesh just because the Ω of the wire and SS mesh were closer in value. But it makes more sense that you have 'more of chance' to have a short with the lower Ω wire if the SS isn't oxidized well under it.
kingorchid on Ebay carries 28 awg, but he's currently outta stock but you can always contact him for the next batch though
I think the short DID & std DID both have 3.5mm wick holes, if you use TomCatt's calculator: PV Web Apps it comes out ta 192mm! 8-o if you do decide ta go w/that # -- better ask emonty ta roll it for ya ;-)

The ohms/inch difference between Kanthal A-1, A, and D for the same gauge are fairly inconsequential:
AWG 28
A-1 0.46 ohms/in
A 0.44 ohms/in
D 0.42 ohms/in
Resistance Wire (ohms/in)
Dang, they shipped my #500 on the 13th airmail, and still hasn't made it across the pond.
The only Kanathal I have on hand is 32g. Do have some 30ga nichrome, so i'm going to see how that works.
