I haven't had any heat build-up issues as you've described. I wonder if you were getting conduction thru the wick to the body with the wick being too tight? One strand gone out of 7 shouldn't make much difference.
That was a good show! Please be sure to post the link here once it's archived, and with a mention of where the Cable talk begins. (for quick referencing).
I guess this is where I step in and finally announce to the world my all reaching, grand business plan. I am in the process of starting a company manufacturing hydrophilic composite wicks. The ceramic slurry idea isn't far off from what I am in the process of making. I still don't have the prototype in my hands, but I have contacted a molecular and chemical engineer in academia that created a coating for exactly this purpose for nasa. I have sent him 3 different material types to coat: 500 SS mesh, 7x7 wire rope, and a plain SS rod. I didn't even think about the screw which I find genius. The material that will be coating all 3 samples has the following properties:
1) Non Conductive!
2) Highly durable - Will not crack, peel, or wear. It's flexible. It can withstand temperatures up to 1000C without degrading.
3) Non Toxic - Will not release any harmful chemicals, was actively used to block hexachromium.
4) Tasteless - will not impart a taste to your juice
5) Has the potential to wick faster than SS rope - coating is naturally super hydrophilic with a contact angle of less than 5 degrees. This is what needs to be tested, and what I'm waiting on the sample for.
It has a very very high potential to be the next big thing for RBAs. I also have some ideas on how to incorporate it into dripping attys by pre bending the SS rods/screws.
Now if you go back and view all my posts in this thread you will see that I was a complete and utter beginner. However, thanks to all the contributors to this thread and doing a whole lot of research I think this will be huge. The process is not easy and the equipment to do it is not cheap. The wicks that I will be manufacturing will not be cheap (cost to end user of about an Aga). I will not be selling the product directly to individuals, only to retailers. I have a day job that I won't be ignoring and I have absolutely no sales experience. Once I get rolling I will be sending samples to retailers and reviewers (the hill giant, phil busardo, Scott Bonner, and others).
Are you using mesh on the wire? I am sure you are. just checking.
Yes i am but my ohms are all over the place. Ikd what i am doing wrong . going to give up for tonight.
Actually, two things. It can also mean that you've found yourself to be in the middle of an Ashram.
Not getting how the Ashram (place of spirituality) affects resistance in StaircaseWit's resistance. Either I am really dense or that was non sequitur.
Got a new twist, or should I say un-twist, on this SS rope idea. I wanted to set-up one of my UD AGA-S atomizers. They have a pretty small body and wick hole. Way too small to drill for my 3.0mm 7x19 rope. So I thought I'd untwist a few of the strands for a smaller bundle.
I cut a length for the height I needed and undid the 7 bundles. One of them was starting to unravel, but I only needed a few. I looked at the unraveled pile of 19 micro strands and decided to unravel a second. I washed them and then wrapped them in a 3/4" mesh roll.
What you see below is the result. It's about 30 loose strands, bundled, wrapped, and torched. I then did a twisted 32g coil that ended up at about 1.1ohms. This set-up is working very well too.
I think the vertical orientation of the strands leads to easy wickablility. What ever it is, it is easy to execute and works just fine and dandy.

Before this was assembled into the tank, I trimmed the protruding wire strands by about half from what is shown above.
Many consider small diameter wick holes and wicks undesirable and problematic. Loose vertical strands inside the wick seems to be a great solution so far.
If you were in an Ashram, you might hear a lot of people chanting "Aum" or "Ohm". There would be "0hms all over the place"
