    Would you say that's a bit taller then if you measure using a pre-cut?

    I don't know, I've never even opened the pack of the included mesh strips to compare. It doesn't seem to be too high for the top cap.

    No problemo, too high for cap would be the only issue, clearly not the case. I use the precut to measure and don't think I could get 3 in there. Build looks real similar to what I do with the rayon.

    The rayon is clamped down pretty tight under the mesh, if you press down on it there is only a little bit of give. Damn great vape.

    I've been meaning for a long time to try something like this. It brings the resistance up a little bit?

    Actually, the resistance with the VV 150 mesh is down around .15. But I vape in TC so it doesn't really matter.

    I meant making the strip a little longer, or maybe even shaping it a little wider too.

    Nevermind, actually that would make the resistance lower, now that I think about it some more.

    No it wouldn't. Same principal as wire wraps. The farther the distance the current has to travel, the more the resistance should be. It's why our mesh is labelled like 0.9 or 1.8 ohms per foot. Then when you cut it down it's less.

    Ok, that's what I was originally thinking so yes, back to the original theory.:wait:

    Yes you had it right the first time. It really doesn't change the resistance all that much though, so it's worth a shot, but I've never even really taken heed of the mesh resistance. for example I am ohming out on my therion right now at .166 and if that was a regular coil I'd be pumping 65+ watts into that thing, but it rips at 40 watts. Honestly, I don't even see how that OHM per foot rating makes any sense. Say we are using 1/2" for a strip and it's 1.8OHM per foot, well a half inch would be at 0.075, but I've never seen a reading that low on my mesh.

    Remember you are reducing the width of the mesh there by increasing the resistance. The resistance of a conductor is calculated by the material, the cross sectional area and the length.

    I skimmed through Mrjustright's youtube video yesterday about the titanium profile. When he was talking about the deck he mentioned might see some tweaks to the design. Look for a V2 after they are done pimping the Unity. It's inevitable, keep those dollars flowing....

    Don't think I will get the Ti, 80 bucks to sit on a shelf is not for me. There must be a list of tweaks by now, but I'm happy with the products as they are. Not quite sure it can get much better.

    If that were the case, adding wraps to a coil would decrease resistance not increase it, however that is not the case. The less mesh the less resistance. There is less material for the current to pass through the less mesh there is. Also increasing the size of coil wraps increases resistance ( going from 2mm id to 3.5mm id can make a big difference ). Mesh operates in much the same way. The reason this happens is because you are putting more resistive material between the positive and negative terminals therefore making the current work harder to complete the circuit.

    Each wrap lengthens the wire, thus increasing resistance. If you were to solder the wraps together the oppisite occurs...

    At best it can be confusing on a good day...Today is not. Switching back and forth between Unity and Profile on topside, when I change to the Profile I forget I have to squonk...:teehee:

    Using a thinner strip of mesh is akin to using a smaller gauge wire. You're creating a narrower pipe for the current to flow through.

    Been using VV's Ni80 and SS316l mesh in my RDA for a month or 2 now and so much better, cant decide which I prefer... but have just been playing around with the SS in TC mode, I was wary of how well it would work but holy shit! Got a build coming out at 0.15ohms (which I'm sure the SS was higher than that last few times I used it but maybe not) but started at 40w / 420F... went up 5w at a time and got to 80w / 420F and it still handles it! Was able to take a draw as long as I could breathe in and just got more dense as I went, no hint of a dry hit!

    Whats really odd though is I'm used to this RDA instant firing on wattage mode to the point where I can't even 5 click to turn off without it firing vapour out, but in TC mode its a really slow ramp up, takes about maybe 2secs to fully kick into life. Cant figure out why, surely it should still fire the same just regulate the max temp? Been ages since I've used TC. First time I've played with it on this Topside Dual.

    @ScottishDuck13 Try turning up the temp and then drop the wattage. I have been experimenting with the 150 mesh at 235C and 55 watts.

    Ohhhh jesus F**K you have just sent my OCD haywire!!!

    this is the first time ive played with TC on the Topside Dual and I usually use Cel. but because it had been on Far. I just kept it at 420... After reading your comment i cycles round to Cel. and WT actual F is going up in 'off' increments!

    213
    218
    223
    228

    WHYYY??? Who does that?!

    But thanks you and I will try your suggestion on my next break (at work)... once ive maybe changed it back, had a lie down, and forget that ever existed...

    Happened to me more than once. Also recall that with SS316L I was changing my cotton more often due to slight burns to the cotton. Have not worked that out yet. Try cycling in the opposite direction, I think that is what I did.

    Its so weird, the 55w @ 228C (grrr) seems a tiny bit quicker, not by much but i dont get it... its not like some of the mods that overshoot the max temp because the wattage is too high and instantly goes into the cooldown mode, it just doesnt fire quickly... Maybe the TCR is slightly off for SS on the device.

    Im on the 200 mesh ohming out at .15 altough im sure its been at 0.2 the previous times ive used it. Whats the 150 like?

    AHA and thank you!!! Fixed the offest temp numbers! Not exactly what you said but you set me on that thought path...

    Iits because it starts at 93C which is random but maxes at 315... if you just click through the top end it ticks over and doesnt fix but if you hold the button down and wait, it hits 315 and stops then you can go back down in nice round 310, 305, 300, 295 etc

    I feel better now :)

    Probably what I did not thinking about it...I was getting dry hits w/ 200 mesh, the 150 seems to give me a low flavor hit before the dry hit. flavor the same, maybe a little softer hit...sort of like the nexmesh, if that makes sense.

    Im liking the 200, not had any dry hits or anything off it yet on wattage or TC mode. Havent tried TCR actually thats a good point, I always forget if its 92 or 93 for 316l, not sure how much of a difference it makes, will maybe give that a try today.

    I notice no difference at all between TC mode (55w/220c) and in TCR mode at 092 (also 55w/220c). Both seem to perform the exact same. Switched back to wattage mode at 55w and fires a lot quicker but doesnt feel as safe taking a longer pull.

    it seems the newer mods are setting the SS setting for 316L

    I took another step in my SS316L mesh experiment..Rather than narrow the 150 mesh to 6.85 mm (width of nexmesh), I left it full width of approx. 10 mm and cut notches at the corners to fit the clamps. The mesh came in at 0.16 ohms and fired with no hotspots. In TC mode it reads 0.14 ohms but jumps to 0.16 when firing using the Topside dual. Flavor is very good.

    The only difference is, I was going to try trimming the wider parts of the ends at an angle.

    The biggest difference I noticed was that TC was more stable, my narrow build came in at .12. there also seems to create more vapor at the same setting... Just an unscientific experiment. I am not sure with the flavor that the profile has there is any appreciative flavor boost by changing anything. I only use one rig in TC, the rest are nexmesh. Can't say SS is worth the extra effort but I have three rolls of it.:devil:

    I like some flavors with SS, others are better with the A1.
    I used TC and Replay on the DNA all the time with coils. Not quite the same with the mesh. I just run them all in power mode. Seems all the same vape to me, just don't forget to squonk the F out of it...no dry hit protection...

    If we're talking about the same thing, it wouldn't make much difference over just leaving it square, but I thought it might be neater and maybe make it fit a hair better.

    Maybe a paper punch, or if you have one of those leather punches with the different sizes.
