I agree that most vaporizers only purpose is to make hot air. That is why the roasting tube design is so important and why I offer so many different kinds. My current favorite is where I sandwich the material between two screens so that the hot air is forced to go through the entire mass of material similar to how espresso is made. No stirring is required and the glass stays cleaner because no fine particles are produced from stirring.
@btka - Thanks for posting the photos. Glad you are enjoying your HI.
@JJ420 - Glad you like my new voltage controllers and good to hear your HI is still performing well.
I wanted to share an idea for cleaning the spent material from your roasting bowl. I hot glued a sewing needle to the cap of a storage container. It is such an easy mod and works really well to keep your screens clean. The needle fits nicely inside when closed.
Here is another item I have been making. It is a silicone tube wrapped with cotton string. There are silicone sleeves on each end to hold the string in place. No more sticky silicone tubing that picks up every piece of dust. This has a very nice feel to it and helps prevent kinking. The tubing is 7/16" x 5/16" high temperature / medical grade.
I recently made a tool that allows me to make short male to male adapters that are lined with a glass tube. This one is made from cocobolo. The glass tube is 13mm and accepts 10mm basket screens. It will work with the HI, UD, Enano, Milanna, LSV, and many other vaporizers using an 18mm F2F adapter. I can also make single male 18mm adapters with glass tube liners.
