Am I missing something? (rebuilding an OCC head)

[Circa Survivor]

Got a subtank a few weeks ago, decided I want to rebuild one of the heads. Made a nice 3mm micro-coil, got the leads where they need to be, but when i give it a few squeezes and a test fire, I can see the legs heating up, which I think is heating up the grommet and giving off that nasty burning rubber smell. Can you not do micro coils in the heads? Does it work best with spaced coils?

I'll try it with micro coil and post back the outcome here if it's worked.....

I've tried and error on this OCC coil ends up dual coil reading 0.45 ohm.

You can build contact coils if you blow torch then before inserting into coil head. Never dry fire then in the coil head, the burnt rubber smell may never go away... How do I know... Done that once and never doing it again...

However spaced wraps are the best in the coil head to get optimal wicking..

yeah never dry fire those occ coils....a small gas torch or even a lighter works, must be used to heat the coil prior to installation

My occ rebuild using 24g kanthal

Only have 28 gauge wire right now and paying attention to how much koh gen do cotton I put in when rebuilding but not having any success making mine as good as the stock coil which is really unusual. Will I benefit more with a 24 or 26 gauge wire?

I did micro coil using 26gauge, as already posted, I burned the coil before inserting it and did not dry burn once installed, came out at 0.96ohms and wicked with japanese organic cotton, been using that coil for just over a week now, and even with the higher resistance than the pre-made 0.50ohm coil, it has been vaping just as good at 22watts, at the time of the build, did think the resistance was to high and planned to use 24gauge next time, but as been working so good, just going to stick with the 26gauge on future builds.

How many wraps?

How many wraps?

6 wraps, I used a screwdriver that just fit in the juice holes for making the coil. so once I inserted the coil, I could put the screwdriver though to hold the coil while doing the leads.

OK thanks. Now I need to order some 26 gauge kanthal. It's always something lol

Just ordered 24 and 26 gauge kanthal to experiment with. 28 gauge just isn't doing it for me. Getting ohms way to high. Good vape but I really want to try to get closer to stock quality.
My protanks and aerotanks are so much better rebuilt but I must say the occ coils from kanger are the best stock I've ever tried. Kudos to kanger on this product.
Next on list buy a mini to play with.
