At the moment the glass beads are at the same level as the end of the glass heater rod with screens holding it all in.
I want to put a few more rows of glass beads on top of that glass heater rod and beads then put the screens on for more heat deflection so hopefully I won't have to be stirring it every 2 hits from it. — Nicholas May
I didn't mean put more glass beads in or on the top of it near where that glass screen is. I meant put more glass beads in the other end just before the hot air path / chamber. — Nicholas May
