Really old pic, but built it to also hold 6 tube mods.

Cellulose, if it's good enough for your cheese, it's good enough for your wick!

Remember when we all made wooden racks for our egos and clearos?

Yeah I never got around to it either...

I made one recently, just went to ace git some scrap wood and drilled some holes then sanded the .... outhe of it

Could be the wick was still caught on the Clapton and pulled apart even though you cut one side. There has been only like 2 reports from people saying this type of thing and kinda, since it's not common, we didn't determine what happened.

Did you maybe burn it by accident then decide to Rewick.

I burned one purposely and it was still in one piece. So when you pulled one side out you had an end, the other side was still in the coil then. Was the Rayon black on the end or just brown? Burned will have a carbon tale on the end.

I mean think about it.. How is it possible to vape away with no wick in the center. You would get horrible dry hits. I think it just pulled apart on you. The reason is because each fiber is a fixed length like 1-1 ½ inches, and all stacked overlaying each other. it will pull apart if you have a bunch of ends left that are 1/8" long fibers and then a bunch of 1" fibers and you pull on the 1" it will seperate or pull from the 1/8" fibers leaving them on the other side.

If you play with a piece of rayon if you grab it at the fiber length say 1" apart, you can not break it it's strong as a rope. If you grab it 2" apart you can easily pull it apart

I think the above is what happened. The following is ideas on how I think you could damage the Rayon. Even though I have never been able to reproduce it in regular use.

You do create a hot spot in the center with a contact coil. Extended overheating there for 200ml I suppose could cause a burn of the Rayon. But many have done contacts past 200ml with the Rayon still fine through the coil. You would see black burnt ends if it burned though. Literally there have only been 2 or 3 that's burned the wick just by user error.

imo, the most common is the wick being loose in the center causing the excess heat to be exasperated in the center of the coil, due to poor wick contact overheating the coil. Most wicks I've seen that burned through were because they were loose not tight and low on available juice to draw into the coil.

When the coil glows the wick can not keep up with that kind of temperature and could spot dry possibly causing the burn under those coils that don't have good contact, if there's not enough juice on the wick.

One other problem with contact coils is you can't see if you have good contact in the middle. Try leaving at least a small space so you can see the wick.

Look at my last posts I'm talking about a similar issue. Being able to see the wick in the coil you can spot when the coils are not making solid contact to the wick. Looking straight across the top of the coil from the side you can see if the wick is looser in the middle.

Tighter is better! But even contact is just as important.

Moral of long winded jumping story... It pulled apart is all.

It didn't pull through, it was definitely burnt to a tight fitting cone on either end. I think that may have been the one time I experimented with a little less wick. Usually I roll/compress it so tightly I have to mechanically stabilize the coil so I don't deform it (and I'm using 26 awg SS or 32/26 clapton so my coils aren't exactly flimsy), which has worked great.
I really only noticed a slight burning occasionally if I was really chain vaping; I normally take short, stiff MTL puffs. I vape 70% or higher VG juice, and I guess the wrap on the clapton was doing its job and keeping a little juice fed to the coil between my puffs.
I just pulled the aforementioned clapton coils out of the derringer and replaced them with naked SS wire. When I snipped + pulled the rayon out of the coils to dry burn them for storage I got a good look at the rayon contacting the coils; after a five days it was still white.
I definitely must have underwicked, I probably would have noticed a lot quicker with plain wire.

Crazy, it's definitely a rare occurrence for that to happen. It must have been low on juice and started to over heat and glowed the middle coils too many times.

I guess I have seen, on bad coils and wick jobs, where the coil overheats and glows on long hits. That if you do burn the Rayon, turning the power down and continuing to vape it will clear up, so I guess essentially it doesn't have a terrible lasting taste when, and after you burn it.

So what it proves is the purity of the cellulose in rayon. Even the ash and burnt rayon is pure. Burnt cotton is horrid, terrible. Rayon you can barely tell it's been burned, and after a few hits it's like nothing even happened.

 

[PaulBHC]

My wife never complained about taste, just that it wasn't making enough vapor.

 

[PaulBHC]

My Jan 17 STM RBA build started tasting bad. Pulled the wick last night. Coil had some gunk. Wick had some brown or black on it. Dry burned coil and rewicked.

3-6ml a day for almost 6 weeks, 40 days, 120-240ml. Probably around 150ml.

That didn't work so well. I think I had rolled the wick too dense. New coil and wick, 28ga 2.4mm 6 wrap .8 ohm. Oops not enough wraps, I prefer over 1.0. Senile. I'll keep using it for a while. I didn't like the 2.8mm, too much for my mouth.

 

[PaulBHC]

Didn't like the Oops so much. Built a 7 wrap for 1.2 ohms in the spare RBA and switched. Getting faster at this.

Up to 77 ml. Mixed up a new batch of juice. Flavoring mix is at a 3:1:1 ratio of Strawberry Ripe, Watermelon Candy and Pinapple. Made a 100 ml batch at 20% flavoring, so it has tons of flavor and it's delicious. So, let's see...for a 10 ml batch it would be 1.2 ml of Strawberry Ripe, .4 ml of Watermelon Candy and .4 ml of Pinapple if anybody wanted to mix themselves up a little trial sample. It can probably be diluted to somethingl like .9 ml, .3 ml and .3 ml and still be plenty strong for people whos tastebuds aren't as dead as mine from decades of abuse. Wick is still performing like a champ so far.

whos maker of the pineapple.
ive tried tpa and fa but prefer tfa's as it has a nicer/sweeter taste and doesnt need steeping.
fa's seems to taste chemically to me, steeping seems to smoothen it somewhat but still do not get that nice pineapple taste as in tpa's.
i generally mix low % of flavorings at around 5%-7%

i generally mix low % of flavorings, much less then yours

I'm with you, tfa pineapple is pretty spot on.

 

[vincom]

agreed and dont need much to get flav.
but damn me i bought 2 bottles of fa pineapple based on users reviews

 

[CbrVapeRR]

I don't have my recipe right now but I like pineapple, strawberry, blueberry, & sweet and tart all tfa.

Oh that sux!!!

 

[CbrVapeRR]

I made an order last week and had to conserve due to funds. I quickly took inventory of what I need and ordered another French vanilla cream, well after it was shipped I realized I had a new 30ml bottle I would of rather another flavor but.. Next time right!

I need to do this for my flavor stash

Right, I was working on a clone that was predominantly pineapple and I was using pineapple as the most flavoring. I found using it as the least that it worked perfect!

 

[CbrVapeRR]

All while using rayon of course!

 

[CbrVapeRR]

Jeremy, hey bro! I know you use dw. I've used it at 10% & 5% it works killer! I'm curious about the water going "bad". I burn through my adv stash really quick, but the gallon jug I'm questioning? I know water can grow funky stuff quick. How long are you going? I don't wanna be vaping funky stuff

 

[CbrVapeRR]

Edit: not a gallon jug of ejuice, but distilled water
