burning rubber... on my rebuilt atomizer!

[CloudZ]

Preliminary results are very good!

Pretty sweet! The vape is flavorful too. Only downside I've found so far is this coil meters out at around 3.4 ohms, so it takes a long time to heat up. I figure the gauge of kanthal, number of wraps, and wattage are all things I can play with to make these micro coils perfect.
Good times!

I'm really glad to hear you are having some success with this. It's pretty fun to try different coils and have them work out. It looks like your wick is fitting good in that coil, but you could try wrapping directly onto the silica as well. It's a little more tricky but it might help you lower your resistance by conforming exactly to the wick shape.

If you can get your resistance down to 2.5ish, it should heat up quick and vape good. I would definitely try fewer wraps and stick with the 32 gauge for now, it works well in clearos for most people. Yeah, 30 will work but you may find it difficult to fit inside that tiny atomizer head, especially with a microcoil. Might be worth a try though, the important thing is to find what works best for you. If anything, I would try to find some 1.5 mm silica or try out some cotton. Cotton is super easy to work with, you just can't dry burn it.

Going back and forth now between 8/9 wrap on 4 mm wick - 32 @ 2.8 and the 30 @ 2.4 (4 twisted 36) I am finding the 30 to be a lot better. More vapor and warmer vape at same wattage. There is quite a bit of room in the protank head. I could have easily fit more in there if your doing tight spaced coils..

4 mm is not a micro coil, its actually fairly big. I don't doubt it easily fits in terms of length. Also, twisted wire has more surface area so it has potential to vape better. I suck at twisting wire, otherwise I would probably do it more often. Might as well buy ribbon kanthal instead, though.

Yeah I know it's not.. Meant to add that..thanks.. the coil wrapping is the same, practically touching coils. Micro seems to be the term for this type of tightly spaced coil. I might have to try a real micro coil and overwick it to see if its better.
Sorry if this is hijacking your thread..

As for burning the rubber.. I forgot, if you think the coil is too close to the insulator, from the bottom, assembled, push a paper clip up to the coil and lightly nudge it up. I always do this and actually just did. I also find it can help with dripping Through the 510. If the coil is sagging it tends to drip.

I think the cutoff diameter for a microcoil is still a grey area because the concept is pretty new. I know they existed in the past but they weren't called "micro". I think a better term is "touching coil", which I said in my first post about it. Personally, I think the cutoff should be 2mm for micro.

I once made 0.6mm coil, perhaps that would be "sub micro". But the truth is it performed terribly because the cotton wick couldn't keep up and I won't ever do it again.

Just wanted to check in and report since I've started wrapping these microcoils I have yet to burn a single rubber grommet. Good times!!!

I'm done with rubber grommet clearo rebuilding. The burnt taste/smell is there permanently. it is there.. I recently got a tobecco oddy clone and can really taste the difference.

Seems that with kanger coils I singe it on the dry durn, or bolting up too high then it's screwed for good. Flavor is ruined that's the main reason I'm no longer getting good flavor on protanks.
