Hello Tobias, John,
Since the last time i wrote here, there werent major progresses in my stove. Real life comes first, work, family obligations, health issues kind of absorbed almost all my time.
Despite that, few more details were added. The feed tunnel and air intake received a double skin. Its mostly to make it look better, but the ceramic and the clay/sand behind it, handle the heat pretty well.
Every time i have the chance, i fire it up. Its tricky to fire it by usual methods (lots of smoke out), but using a small blow torch for a few seconds helps to create the needed draft to get it going. It burns smooth without big issues, just need to make sure the firewood doesnt get stuck in the feeding chamber. I kept it burning for long hours, 6 to 8 hours with hardwood(oak and olivewood). So far so good
Next month, due to professinal reasons, will be spent out of the country, so, no progress will take place before february.
A happy new year for all is my sincere wish.
