Orestes - Sorry to hear about your glass tube. You do have to treat them with care. It is best not to take them apart for cleaning. Cotton swabs and alcohol will clean up anything left in the tube after rinsing with alcohol in the protective poly tube. I do sell replacement glass tubes for $10 which include a new silicone seal and a protective poly tube. You re-use the stainless steel parts from the broken tube. Stretch the new silicone seal over the stainless steel tube and adjust so the edges are even. Wet the silicone and gently rock it into the glass tube. Very cool to see how you have adapted the stainless steel roasting tube to Ed's wood tube. It will fit into anything with a 1/4" hole. biojuggernaut - The wood Toasty Tubes are $30. The poly and gas Toasty Tubes are $20. The poly tube would probably work the best for a down stem as they are stronger than glass. A short section of 3/8" silicone tubing stretched over the poly tube gives it a diameter of approximately 13mm or 1/2". The silicone tubing stretched over the wood Toasty Tubes should work as well. I have successfully vaporized hash in my Toasty Tubes. I use the pointy end of a bamboo skewer to poke holes for air to flow through. I also use the bamboo skewer to stir and aerate the herb in the Toasty Tube. When the screens eventually do get clogged, I reposition the screen so it sets edgewise in the Toasty Tube and draw hot air over it. The clogged part of the screen (edges) is now in the hottest airflow (center of the tube). Rotate the screen a few times so all edges see the hot air flow. I usually get several good hits from the screen. It make a very efficient roasting tube even more efficient. The screen can now be brushed clean and re-installed. A clean screen give the best performance.
