Thanks for posting the video
@P.A.M.
Glad you are enjoying your iHeat.
How is your iHeat treating you
@Shit Snacks ?
Discovered that a silicone sleeve on my 15mm glass roasting tubes for the HI allows it to fit nicely into the iHeat, Lil' Bud, and Timber. The basket screen is 10mm so you can roast a bit less material at a time. I like to finish off the roasting tube using my HI to get it darkly roasted. The glass is fairly thick which provides some cooling and is also harder to break when dropped.
Here is another idea I had for the wooden roasting tube glass inserts. I filed three slits into the end of a 12mm test tube and then flame polished. The slits are located to draw the air to the outside of the roasting tube. The center of the tube is closed off to divert the hot air through the slits. The majority of the debris that does get through the screen gets stuck to the end of the glass tube. The hot air impinging upon the end of the glass tube also removes some of the heat so it is not a direct path to your mouth. I have also placed some hemp fiber into the open end of the glass tube that is held in place w/ a 10mm basket screen. The hemp fiber acts as a filter to smooth the vapor. I can also do it w/ 10mm glass test tubes.
Here is an end view.
Planning to try the slit end tube for Heat Island glass heater covers. It should throw the hot air out to the edge of the roasting bowl for more even roasting.
