Pump it up a bit, dsy5. Go to 8.5. hahahaha

Promise ya dsy5, so long as the wick is a couple of mm below the tip of tube, juice will stay out. I've observed them closely at 10x magnification and the small opening at the top is not a problem. If the bottom leaks tho, it's game over.

I say stick with either the epoxy or the JB weld on the bottom. But that's just me talking.

Tomorrow I will try the FQ with fp mortar on both ends - I kind of have reservations about having it in the juice, being not a food grade item and all. Or I can wait for K3vin to try it - if we don't hear from him in a couple of days, I can start looking for something else:D
[Sorry, Kev, bad joke...]

It will pick apart with the needle, but it takes some work. I was able to remove it on the only piece I have left with a needle, but I don't think under operation that it will disintegrate or crumble. I have soaked it in water overnight on another tube to see if it would be easier to remove and it didn't even darken it, so I'm thinking it would be okay in the juice. But then again, who knows what PG or VG might do to it, or even some juices that crack polycarbonate tanks.

Edit: I would like to get my hands on some of that stuff that Scott found...

I have tube left dsy5, so don't fret. I can send out more.

I think that a food grade silicone would work in the bottom, but with the way the hi-temp silicone acted on the top, I'm not so sure. It was very slippery on the glass. Epoxy could be good, if it can be removed for a rebuild.

Yea. Need to think about rebuild components..but man that is a smalllllllllllllll tube lol

Oh I got it... Silver solder... Oh never mind tube would get too hot and it would just run down.. Butttttt, it could be used on the bottom which would be kept cool jn the juice,.

Then just heat up the fq and it would drop right out..you wouldn't even need a soldering gun, just heat the very end of the fq

Ok, I just had to pull out the BSD element and have a look. It does have some juice down in the tube. It isn't bad, and I would bet it would last a good long time, but there is browned liquid around the coils. I will try to get a good pic, but I'm not a photography (or video) expert here. Maybe it's just the coils reacting to vapor? Big D?

No, I'm pretty sure that when the juice that gets in the tube hits those red hot coils, it burns, baby. I have seen that happen with mine.

A tip for all you guys trying out the small FQ tubing - twisting the NR to the Kanthal is about the only way you're going to get it into that tube. And, you need some thin wire. I tried some of the 24 ga silver wire I had, and it is just too big. What I have been using is some stranded appliance wire. I strip off the insulation and use the individual strands. Someone also once suggested using the replacement stranded lamp cord they sell at Home Depot or Lowes. Anyway, it helps getting something as small as possible.

Hmm. Must have gotten in from the top. Either the wick is a little to close to the top, and juice is making the climb up the tube. Or condensation collecting on the positive wire is running back down. Seems like an awful lot for one days use. Could be that with the wire between the tube and mesh, you have a little extra volcano action.

I do see where you had the small piece of wire around the top of the wick to close it off like I suggested, so maybe it is just a bit loose. Only way to know is to watch it as you fire it and see.

Bottom seal seems good, so I doubt it's from there.

That reminds me dsy, radio shack sells some very high gauge coil winding copper wire.. And it is coated...that's what I basically saw in my dcc's when I took them apart.. Coated copper wire

I built my very first wick using that, but I burned all the varnish coating off it. Then I got to thinking about copper supposedly reacting adversely with PG or VG and didn't use it again. The top end of the coil would probably burn off the varnish anyway, seeing how hot it gets. But on the bottom it would probably be fine.
