Wick materials. Safe vs dangerous.

Sounds nice Roadrash.... but I can not see the pic's you added.... they do not show up, please try again

[roadrash]

the pictures that did not show are just smileys from another site. LOL

Maybe some wick pics tomorrow after some use.

Meat, I am curious how you did that. Did you wrap the mesh in a tube shape and thread the bamboo through after oxidization?-Sam

I roll it then torch it, then unroll it and wrap it around the bamboo. It will short in a few spots but just move the coil around until it stops. Once it goes through a few ml of juice, the whole thing will be oxidized really well.

Nice thing is Closed coil heating element (CCHE).

CCHE is made of needle from siringe (stainless steel) Ideal heating element for organics. The only thing I don't like - it's about 30 min to make one. But one CCHE can work for a month or even more just changing wicks. Depends on how accurate you replace the wick, the weak plase is nichrome tails (at zero mark on the second foto).

Here is the link to russian thread. If you are interested in how to make this I will tell in more detail (after 10 of may).

After reading 10 posts via google translate, I have no idea what happened. Waiting for your info after May 10.

Evilgrym, from what I understand, its pigtail coil with 2 nichrome wires, put inside a stainless steel syringe (oxidized so it doesnt short), then bend the syringe with the coil inside, coil heats up > heats stainless steel of syringe, the heating coil never touches the wick, only syringe, so its easier to clean and healthier.

is that correct? whats the gauge of the syringe? isnt that hard to bend?

Looks like the nichrome is threaded through the stainless tubing which creates a rigid coil? Seems this would take a lot more power to heat up and hold residual heat longer after the button is released.

Just jumping in to follow this thread.
Vape on.

Yes it's coil inside a tube. I used 5ml,10ml , 20ml siringe needles. Most suitable is 5 & 10 about
0.7mm diameter. What about additional time to heat it up & cool down - forget it. 2 seconds to heat it before first puff, then you vape with no additional heating time because it's already hot and a cople of seconds to cool down after you finished vaping. Vaporisation is the most effective way to cool down anything. (telling as a graduated aviation engeneer). To cool it quikly do the last poof without heating.
