Thanks for posting the photo and video @
momofthegoons A very nice first video. That glass heater cover can really crank out the heat. Makes it a tough decision on which to get. The WonG seems to be working wight.

Bvapst - There are only two heater cover options. The glass cover or the ss cover. I have to install a 1/4" ss sleeve over the heating element for the glass cover. The ss cover needs no sleeve over the heating element so it has slightly better air flow. The ss roasting tubes are the only tubes that won't work with the glass heater cover.
I have been doing more experimenting with roasting tubes. The great luck I was having with the 18mm glass roasting tubes and fluidization led me to try the same thing with my 10mm roasting tubes for the HI. I had previously posted a photo of a wine cork tube I had made using 13mm glass tubing and a 1/2" screen. I just added another glass tube and screen to the tip.
In the photo below you can see how the glass tubes are arranged inside of the wine corks and locations of the screens. I replaced the mouthpiece tube with a 14mm GonG tube and tapered the cork to fit an 18mm fitting for the tube on top. The same tube will fit either 14mm or 18mm. Perfect for a HT. This tube won't work with the old style HI though. It needs to fit into a 1" diameter hole.
Since there are two screens, you can blow back into the roasting tube to clear the material from the second screen. It fluffs and stirs the material at the same time. The tip cork can be removed so that it can be used as a regular roasting tube and the heater cover can be inserted farther for higher temperatures. The screens are very fine and keep the glass and your lungs much cleaner.
I also figured out a way to do the same thing with my 5/16" ss roasting tips so that I can use 5/16" screens. This will prevent the screens from ever flipping and change out will be a snap. I won't have to dimple tubes any more. It will be similar to my slide in style tips, but the tubes will be held with some smaller cork pieces that I ordered. Will post some photos when I get some made.
Back to the laboratory.
