Re: Has anyone tried this...
LOL It looks like a nice, shiny tumbler tipped upside down and drilled out for airflow. Nice, though. It works similar to the way I use my homemade screen. On my Mya it fits right over the bowl and sits on the tray is it should. With my larger bowls, though, it just sits atop the bowl but gets a good enough seal to work properly. And like this one pictured, my homemade one needs to be handled gingerly with mits or potholders cuz it gets hot. Smoke happy.
Al Fakher Large Solid and a bowl of DM . . . life is good!
