Looking good! And clean,
Yes ovenbuilders children better not suffer from claustrophobia!
Once a hightened the floor in my first WFO a got stuck in the oven when I squeezed in to the back with my whole torso and arms to inspect and clean the new floor.
There I was alone (Stupid!) in a garden in the middle of nowhere in Greece, the air was getting stale because of my large or so blocking the airflow......Luckily I have experience in scuba and freediving so I lowered my breathing and refrained from panic, relaxed and slowly squeezed out.
That was a good lesson. Never dive into the sea without a buddy, same for your WFO.
