Hiya Moov,
I hope you're still able to see replies on this thread and answer them!
I had a go at replicating this burner based on your drawing but I'm having a little teething trouble, I think I may have ruined things with too small an air pipe and possibly not having a bit enough tray but I'm really not sure...any chance you could refresh that youtube link so I can see the real thing ion action?
Cheers,
Tom.
