Instead of the epoxy in the bottom I just used a tiny bit of cotton stuffed down in there. It won't ever burn and keeps things from touching. I can't get the wick rolled super tight so I just use less mesh. I would say about 22mm or so? I also keep my wick really short like Rusalka does. Having the rolling paper on there helps because once it burns away your wick has a tiny little space around it that helps the coil not dig into the mesh wick and keeps the shorts away.
I think the important part is to not have the wick fitting too tight in the upper hole. It should just pass through it without much resistance. This allows for air to re-enter the top chamber and aids in wicking as well.
You can also use a tiny bit of cotton on the wick where it passes into the top tank to keep it isolated. Just roll the wick over a cotton ball until it catches a few fibers...you don't need much at all!
Good luck!
Great, thanks for the advice. Sounds good. So, if I cant get this work Im gonna be hunting you down in Everett lol.
