SS Mesh coils with higher resistance

[madstabber]

This is what I want. Stainless steel mesh coils that ohm out around .5 would be perfect. Does anybody know if any company is working on giving us some more Ss mesh coil options? I believe ss430 ohms higher than 316 so maybe that would be a better choice. Does anyone here know where I can get some different grades of stainless mesh? Also what grade of ss has the highest resistance? Or Is there another metal that can be used in tc+power mode that has a high resistance and comes in mesh? Basically I like using mesh and I prefer vaping around .5 ohm. How can I make this happen with the size of mesh the current rda’s and rta’s use?

Not that I'm aware of. Maybe some sort of honeycomb type thing?

Have you tried cutting down the width, while leaving the length the same? Cutting length will lower resistance but trimming the width will raise it.

Is that correct? I thought more mesh, higher resistance regardless of where. I realize getting to a half an ohm isn’t going to happen with ss but 430 ss should be a little bit higher I think. Does anyone know of a good source for 430 mesh with options for openings per square inch? I can’t think of what that’s called but hopefully that made sense, like 150-200-300 mesh for how many openings per square inch I believe it’s measured in.

Yeah it's odd to think of it but it works. Think of mesh like a road or bridge, where round wire is like a pipe or straw. The narrower width creates more resistance, like a 4 lane highway can handle more traffic faster than a 2 lane road.

Forgot to add, it won't get you huge increases but like you said, something's better than nothing.

That’s a good analogy – excellent post!

Thanks, wish I could take credit for it,lol. I couldn't wrap my head around it at first, till a buddy explained it like that to me. It's one of those can't see the forest for the trees things, lol.

Wire is wire but mesh is a different animal when you're used to just plain old Kanthal. One has to really just slow down and think about it but once it clicks, you want to slap yourself because it is so simple.

Thank you @papergoblin, I’ve been at this awhile now and I’m still learning everyday from the good people of ECF. The analogy was an excellent way to help a simpleton like myself understand. It’s odd that It does raise resistance but it’s good to know and will be quite useful in my search for the mythical half ohm mesh coil.

Still wondering if anybody has a good place to get some 430 grade SS mesh? Advancedvapesupply has some 430 grade coils I’m gonna try out to see how it Vapes. They don’t sell any mesh unfortunately so I’m all ears if someone has the hookup.

Not finding much for 430, wirecloth is about the only place in the US but not sure they retail, doesn't look like it. Then if they do, not sure they'd sell it to you if you mention vaping. They are out of Ohio, you could look them up and give it a shot. Everything else links back to European sites and again not sure about retail. I haven't looked and you may have mentioned it (if so never mind) but you could try fasttech.

Yea I’m not having much luck sourcing any. I’ll check to see if fasttech has anything but I think I’m S.O.L. until some vape companies start offering more rebuildable mesh options. I emailed wotofo asking them to make some ss mesh for the Profile. They make Kanthal so it doesn’t seem like it would be a big deal to start making some ss ones also. I have a spool of the Vandy Vape ss 200 mesh to hold me over until some companies wise up and realize there is a market for ss mesh. I only use ss for standard coils and I know there are many other vapers like me so now mesh just needs to keep growing. It’s just a matter of time. Thanks for your help, much appreciated.

pretty much on the same topic so, is it ok if i hijack your thread lmfao
I'd prefer something higher ohm'ed myself...but I'm wishful thinking more towards 1ohm
but .5 would be better than the .18's i'm finding

part two, where to find a good mesh for a decent price
either precut or on a roll
so far all i'm finding is 10 pieces for about $4.20
don't know if it matters but it's for the wotofo profile rda
and I really don't mind if it's kanthal or ss

Vandy vape and digiflavor both sell spools of Kanthal and two types of SS. Other than that you can find some on eBay although I’ve never bought any there so can’t vouch for it.

You might try contacting AVS for ideas where to source 430.

 

[smacuser]

links?

That sounded weird. But I looked up the formula for resistance.

p is a constant. So we are left with L(Length) divided by A(Area). The smaller the area the higher the resistance. The greater the length the higher the resistance. Cutting the sides would decrease the area which would increase the resistance.

It's been almost 3 years since I've used it so don't remember any of the specs on a sheet of mesh I have other than it is SS 400 mesh. For my use it was the wick in a NoName NoGain RDA, not the coil. I found when/where I bought the NoGain, but didn't find where I bought the mesh though.

Which Mesh RDA do you have?

I have Digiflavor Mesh Pro's, Vandy Vape's Mesh RDA's and Wotofo Profile Mesh RDA's. If one of them maybe I can play a little with this mesh to see if for it's size of clamps & headspace .5Ω is doable.

I had a tough time wrapping my head around it too, till I thought about wire. Kinda the same concept...the thinner the wire, the higher the resistance. So it finally clicked in my lil head. Thank you for posting the formula, shows why it makes sense now. I just knew how the wire worked, gauge wise, not why it worked that way....now I know

SS430 has the lowest resistance of all the SS wires we use, it does have the highest TCR though. I highly doubt you are going to get anywhere near a 0.5 ohm build with mesh and why does it have to be so high?

Possibly if you cut the mesh in a thin strip and wrapped it into a coil like you would ribbon wire, it might get close. Would be a total nightmare to wick with all those edges.

I use to love mesh as a wick in genny's, they provided awesome flavor. For me, using mesh as a coil material is a novelty like ceramic coils were. I can get the same if not better flavor and performance with regular coils, also there's no chance of that dry hit from hell like you can get from mesh.

Good luck on your search though.

MFS has precut, spool and sheet mesh, I still have some of their 8.5"x11" sheets.
Wicks / Wire / Mesh / Cotton
