how did you encase the coil like that,, is that hollow inside and just glassed on the ends??/
Id like to know how many heat cool cycles you get b4 it cracks.. looks really good but looks like the wire is glowing in the glass connection..
Just copying Moktarino's process: make a coil, slide a short length of borosilicate capillary tube onto it, and hold a butane lighter to it. The glass melts pretty fast and both ends close up. It also ends up hugging the coil itself pretty tightly (I probably overdid it a little bit with my 2nd one).
I'm not sure if there's any air in there. I suppose I could try snapping it in half to see if there is a cavity in there. I will have to experiment with heat cycling.
Wow Roadkill, that looks great... I like the concept as well, might try it for my design.
Could you crimp leads on b4 you encase in glass? That way nichrome is not exposed to air or damage and the glass will hold the connection point.
Moktarino has tried to put copper leads in the glass but (we discussed this in the
thread a bit back) the copper expands quite a bit more than the Nichrome and cracks the glass. I'm hoping I can weld thinner copper leads to it. But maybe we could try other metals for the leads, it would be great to not have to solder anything!
Really good progress Roadkill. I agree it would be nice to get some life testing done, but this has been a great stride in the right direction... keep up the good work.
Thanks, will try to test some more tonight!
Wow, that is a lot of turns. Although I guess if you're using 36ga you'd have to use more than the 6 or so I've been using. Notice how the glass melts every time it gets hot, that should serve to fix any cracks that could develop.
It could also serve to embed any gunky stuff into the glass itself, but time will tell. When the element is "wet" it may not get hot enough to soften the glass, though.
Yeah, I'm trying to get my hands on 38 and 40ga. 36ga might be stronger but I feel like since it's coated in glass we can get away with using smaller wire more efficiently (less power and space used).
When it's wet hopefully it
doesn't go above 260 deg C. But maybe dry-burning (under a higher voltage too?) will be a good method of "repair" or "maintenance" for these
coils!
Have either of you 2 guys moktarino or roadkill. Made the glass enclosure small enough to fit in one of the ceramic cups from old atty's? Or are you guys going to wrap it am make a hybrid cartomizer form these. Great progress though.. great finds on the glass pyrex tubing and stuffing the coil in there. I need to get some of those tubes asap, and try myself.

Moktarino I believe has tried his in an 801(?). I have no dead atty's to experiment on

.. but I was planning on trying to develop a new fully-reusable cartomizer anyway (not that I have any cartos to experiment on either, haha). Credit for the design goes to Moktarino, he found the cap tubes and melted 'em right up. I had similar ideas but never thought to try the "bulb atomizer" on such a small scale. As it turns out, it works better and is much simpler/easier to build... so thanks Moktarino!
