Actually, I've given the vertical coil cartomizers alot of thought. I wish I had a bunch of duds to work with.
Did you manage to remove the threaded fitting without destroying it? It appears if you can do that, the insides should slide out. I looked down the hole in my KR808 and I can see straight through it. I'm anxious to see exactly how they are working. The pic I saw showed a center post where the coil(already removed) was hanging vertical, obviously just off center, and everything else wrapped or packed around it. Couldnt tell more than that from the pic.
If you are going to persue this, start a thread on rebuilding them. Post pics and details of how to disassemble them. Many own them and they get good reports of durability as does the greencig cartomizer.
Feel free to post a link to your thread here.
All info on keeping attys going is important.
From the picture I saw its wide open on the "hanger" and would be much easier for many , maybe everyone, to rework if the fitting can be removed in a way to make it reuseable. Many will jump in with ideas/comments and thats good. Even if it takes 2 attys to make a good one that is rebuildable, thats a big plus. Turning 20 dead attys into 10 rebuildable ones is a great return!
As I've stated before, this thread is a way to do it. Is it the right way? It's just a way that works , that I can do, and I hope others can learn from it and do it. I don't mind criticism because I'm not sure anyone can say abt thier method "my way is the right way". Its better for everyone if many ways are posted and the reader can decide which is the best or easiest for them to do or attempt. The main focus is repairing a costly component, that will fail and someday may not be available.
As far as the connecting wires to the coil. I've never had any luck using the existing wires. It seems the eliquid causes the coating to swell and trying to connect and solder the ends down in the ceramic cup is tough to say the least.
The atty will pull just over 1A. Stranded wire carries more current than solid wire. If you look on a current draw table, the recommended wire is always to large to fit through the holes in the ceramic cup. The coating on the wire will vary in thickness also. Drilling the wire holes larger in ceramic is another story. The wire I've seen in dead attys that go from the fittin to the coil appear to be to small for the current, but they do work. They all also have a very thin coating/insulation. If you have a source of stranded wire that fits through the cups hole, I'd cut 2 3" lengths solder it to a coil and connect it to the battery. If it will run the atty red hot for 30 seconds to a minute with out melting the coating, it should be fine.
I use the solid red enameled wire in the Rat Shack 3 pack. I make a 1/16" "U" or "V" on each end of the coil and on the enameled wire. I hook them together then squeeze all 4 "U"'s closed , then solder. It makes a good physical connection so if the solder softens the joint cannot come apart. Using a toothpick to put a dab of soldering paste on the crimped "U"'s makes soldering much easier. The flux should contain Zinc Chloride and a 35watt soldering will do the job in abt 3-5sec. Then rinse with water to remove the excess flux. Without the paste, nichrome wire is very hard to solder.
The sharp edge of the cup hole can scrape the enamel off the wire. The wire I mentioned slides through easily, but if both were scraped exposing bare wire, a short could occur from the metal mesh reservior below the cup.
I normally do not remove the mesh. I remove the old original wire, then enlarge the hole it was in with a pointed tool. Once the new wire is inserted, a short piece of wire insulation can be slipped over the enameled wire against the cup bottom and the mesh pressed against it to hold it in place. No short circuits this way and it only has to be done on the 1st rebuild. Most glues arent a good idea when in contact with eliquid. Leaching is possible and most, even epoxy will turn rubbery. Silicone can be used on the outside of the insulation sleeve in the gap between it and the metal mesh. The mesh/atty should be thourghly rinsed in alcohol prior to rebuilding so the silicone will adhere.
