burnt rubber taste Evod and Protank 2 coils

[JammyB]

Hey guys,

I've recently rebuild my coils and for some reason this round has resulted in very bad rubber tastes smells when I fire them up.

I've already rebuilt them once using 32ga Kanthal, on 2mm silica, 6 wraps and it was fine, not bad taste, and vaped like a champ.

This time, everything the same, just 5 wraps instead of 6, and near enough all of them taste of rubber!

What gives? Before I rip them apart and do 6 wraps instead to see if that removes the taste, anything else I'm doing that's causing this?

Thanks

J

sounds like your coil legs are heating up and burning the rubber insulator, what resistance are you getting from them? i aim for 1.5-1.7ohms, i use the drill bit/coil then wick with cotton method as im not a fan of silica. also make sure that its not shorting on the edge of the housing.

I think you might have burned the rubber bung. When you recoiled what ohm reading were you getting with your setup?

 

[JammyB]

Well I can't say for certain as I'm using a multimeter rather than a proper ohm reader for coils but I was getting ~2.5ohm with 6 wraps and 2.2 with 5 wraps.

I make sure that there's no short by using a pin and pushing the end coils back into the centre.

Now that I've already burnt them (which i think is right as I pulled one apart just now and have scorch marks) does that mean the coil will always taste like that even if I re-wick and re-coil?

did you account for the resistance of your multimeter? touch the two probes together then subtract that reading from the reading you get from the coil head, should give you a closer reading. My multimeter gives a 0.5-0.6 ohm resistance when the probes are touched together so i subtract this from the reading. also make sure you are touching the tips of the probes together as that would be where you are touching the coil head. I've used other multimeters with as low as 0.2ohm resistance and as high as 0.9ohm resistance. its best to check.

try soaking the rubber in alcohol it might get rid of the burnt taste, you need to use the needle through the coil/silica method and raise your wick slightly out of the cup, also try doing microcoils, you can keep them smaller and easier to manipulate while in the gap.

plenty of tutorial videos on youtube, riptrippers one is good imo

You can also try using no-resistance - resistance wires, which will not heat up the grommet. Available from stealthvape and greyhaze as well, of course, as fasttech

Hmm, I'll try to use the needle method to seat the coil in before putting the rubber grommet back in.

I've had a look through the microcoil method...Wish I hadn't just bought 20metres of 32ga and 5 meters of silica

Oh and thanks veedubz about the tip on getting the residence of the multimeter, it never occurred to me!

This is how I do mine

Cheers - Have you had any issues with the legs getting too hot and making the grommet smell with micro coils?
