I have always used these stoves without the potstand for baking, warming or for the kids marshmallows once it has died down after boiling. Some of the mugs have a distinct taper and some are straighter. The straighter ones seem to do a little better but there just seems to be an airflow problem between the pot and the stove.
One thing that occurred to me was that for a couple of years I used nothing but the skinniest pots. The potstand helped to keep the fire narrow. I have been testing using wider pots this past year and it makes a real difference in the flame pattern. SOO...I was thinking that the potstand can be for when you are interested in a quick boil or have a skinny pot.
I did remove the stoking hole from the potstand. It makes the potstand short enough (1-1/2") to fit inside the stove, but around the mug and it still allows the flame to accelerate and concentrate on the pot.
the pile of wood shown here was almost enough for 2 boils.


the potstand carries inside the stove around the mug.
