The small fuel size does behave well, in my gasifier size, as where the larger sized fuel are having more difficulty to start up.
For me, the small sized charcoal does a good job to “contain” the heat in a small area.
I prefer the fast startup, specially when doing show’s, however depending the kind of work i did with the gasifier, starting just takes longer and longer if i don’t clean out / refill.
For a number of reasons i just stick with the daily routine and point this out to the students. ( in the hope they follow the lead and focus themselves on quality )
Nothing wrong with doing it other ways… However talking did never make good shaftpower as there are a lot of bystanders that think they can do better then the actual do-ers ( DOW members who actually DO )
Most joy in my life comes from do-ers , as yourselve, who do show what they achieve… so much i can learn every day…
I am an old dog, eager to learn some new tricks all the time…
