I found some marine grade epoxy that I'll be trying tomorrow. It's supposed to adhere to glass well. Not sure if there will be any adverse issues just yet.
I have some FQ tubing coming later this week, so I'll be able to get in on the fun with y'all trying to seal those buggers up.
Been thinking about the juice in the top thing. Could be I'm not having that issue with the top not being completely sealed because of the taper. Though even then, if the wick is less than 2mm from the end, juice will still climb the tube and let a small amount in. As long as I have more than 2mm of naked tube above the wick, there is no problem.
I'm getting pretty good at making these with the glass now. Built six in a couple of hours this evening. Only broke one tube coiling it, so that's a new record lol.
Wish I could just solder the connections. Would be so much easier than crimping.
I need to do some tinkering with this idea. So melting the tube to seal it has been tried? Did anyone try putting a vacuum on the tube and then melt to seal it? You should be able to vacuum the tube and seal it at both ends without any issues and it would make the coil last for a very long time.
I'm sure that with the huge amount of vapor your setup is putting out, Big D, unless it's fully sealed up top, there will be some leeching. Need to find some way of fully sealing. Not sure who it was that posted it, but he mentioned the 'vacuum bulb' thing. I'm sure that there is a method to that madness for longevity. Kind of cool that the Pyrex is malleable enough to close up the top a bit.
How about using that enameled resistance wire without any NR?
Edit: Nah that won't work for the lengths you use. I'm going to try and come up with a way to run both leads out the top, or maybe even running it up the side of the tube inside of the mesh.
Il will try melting some Pyrex onto the fq again tomorrow..
We are surely getting close to an easy solution..I am going to have to get my coils closer together.. Another issue I am having is head room when I put the cap back on top of my did unit..
Can't we use silver solder to just solder the nr to the coil wire???
Heat shrink tubing for bottom... Wouldn't have to wait for jb weld, and also for connecting coil and nr together after twisting and it crimping..
JB cures pretty quick with a little heat from a lighter
What about having the FQ tube a little longer and using a pointy silicone carto plug for the top????
I found the fireplace repair,, will hold up to 2000 deg.. Also found some silicone but only goes to 500 degrees.. Also found some heat shrink tubing. May not be small enough. Probably have to go to radio shack..
Do you have the facilities to do this?
