Ambient Temp 22 C
Hotbin had to be refilled to the brim as it had slumped to less than a quarter full and the internal temp has begun to drop rapidly to less than 40 C - so I filled it up to the top with a mixture of weeds, grass and card, with a few handfuls of wood chips as bulking agent.
Found a slight issue when I tried to close the lid - if any debris gets on the flat surface...
The lid wont shut!
Easily fixed, though - just clear the debris away :-)
Dalek has slumped by 45 cm from the initial max fill level.
Internal temp in middle of surface layer 56 C - still working on initial charge of material.
Lots of steam.
