Re-wicking a micro coil

[Richard75]

Hey guys,

So I've been using micros and cotton wicks for a little while now (6 wraps of 28g for 0.9-1 ohm), and it's working really well in my Hornet. However, whenever I rewick the coil (remove old wick, dry burn, rinse, dry and rewick) I tend to get a weird metallic taste. This doesn't happen with a freshly built coil, but within the first one or two wick changes. I examine my coils, and there's no way it's a short of any kind. Could there possibly be a break in period for rewicked micros?

I'll also add that this usually happens when using lighter juices. I did a rewicking and switched to a darker juice, and there was no problem. I did a third rewicking, switched back to a lighter juice, and the metallic taste came on.

Or is it just in my head?

I dont really get a metallic taste,but it does take a little bit for the cotton to "break in" to get the full flavor. What kind of cotton are you using?

Cotton balls... stretched out and rolled fairly tight. The bizarre thing is, a freshly built coil doesn't do this. It's only after I rewick it one or sometimes two times.

Maybe some of the more experienced Reoville peeps will have some ideas...im stumped lol

Me too! I'm not exactly a noob with building coils, either. Been doing it for more than 6 months...

Seems kinda oddball, but this happened to me earlier today so I'll share anyway:
How well are you drying the atty before reusing it? I pulled my cotton, dry burned, rinsed under the faucet, dried with q-tip and paper towel, then rewicked, juiced, and vaped.
Turns out some tap water was still sitting in the wire posts which gave me a really strange "minerally" flavor. That could be the taste your describing.
Or not, what do I know

That is fairly common after a rewicking. 10 hits or so and it goes away

I also agree that if your rinsing it, there may be some water trapped. Possibly under the floor or in posts like mentioned above

Doesn't matter. I miss my cheese steaks, soft pretzels and... you guessed it.

Ugh. Your username is just not right. I just moved away from the area and i'm itching for some home town flavor.

</OT>

Heading out to get some cotton balls now. I have to see what it's all about.

Instead of cotton balls I recommend going to CVS and getting a box of sterilized rolled cotton.

I never thought about water in the posts! I usually dry mine pretty well, and even do a quick fire after rinsing to make sure the coils are dry. If it happens again, I'll give it a bit more time.

Thank you all! At least I know I'm not crazy..... yet.

Hahaha, I just had a couple soft pretzels and wawa chocolate milk for breakfast.

Yea, I'm usually more OCD about it but was in a hurry this morning. Even after you dry and give a second burn after rinsing, try blowing some air at the holes in the posts - there's still usually a few drops trapped in there.
Depending on the water quality in your area, that can really change the flavor for the first few pulls.

Ever look a used coil under high(ish) magnification (I use an adjustable loupe)? I see pits (and sometimes cracks) in the wire, usually in the middle 2-3 wraps. Hmmm, where did that metal go that used to be in those pits?

Also, often times after a few cycles/uses of rewicking dry burning and then rinsing, the clean coil will have a redish (rust?) tint to it, especially noticeable with Kanthal. In my experience, this coincides with an odd flavor on a clean (but used) coil.

After rinsing, I take a paper towel and try to get as much water as I can out of the nooks and crannys of the atty. Such as; the interior of the posts and around the gasket and under the screw heads, etc. The RM2 in particular seems to hold water under the ceramic deck. I've taken to using compressed air to dry all my attys after rinsing.

End rambling...

I never seem to keep a coil more than a couple of days

As soon as I try to replace a new wick in the coils they are so small they get entangled and break. I use a cheap watch repair kit 124 Pcs Watchmaker Watch Repair Tool Kit Back Case Opener Remover Spring Pin Bar | eBay

I use the 3 metal pin removers to make the coils.
