How small diameter do you burn?

I think Mike Belben has a rig where it's hinged near the powerhead, but cuts on top, so the tip is out of the way when not cutting and the chips are blown away, rather than toward the operator.

I keep a very small fire for the grow tent, 2 or 3 little round sticks. Don't need no fire heat at all up in the living room or great room on the second floor. Bright sunny day will deliver 85F degrees free of charge. In fact a window will be going up shortly.

I  cut down to 2" . The reason is, cause I dont like it laying all over the place. SOmetimes I stack the smaller stuff up and cut 10 at a time . it is all BTU's. In the spring time, when I only burn once every 2 days or so,by then , I am sick and tired of burning my good wood so I just go out and find popple branches to make a quick fire to get the floor warm  ( radiant floor)
