what surprises me a lot is that there is no fisurre (cracks...) whatsoever .. not even a hairline. I wonder if this has to do with the fact that I used sifted donkey poo in the last 5 cm of the cob .. Its absolutely fab! RMS rules !!
The heat riser is an old waterboiler btw

Awesome Petra; That looks great ! And i'm sure it works as good as it looks ! Now you can convince all your friends and neighbors to build one as well. I have struggled with cracks (fissure's) in my cob .... maybe I should get some donkey poo ?

thanks Thomas! And yes donkey poo, horse poo. It's the small fiber youknow .. they chew and chew but as it is grass they eat there is mini straw left in the poo which I think makes small connections to keep the sand and the clay together. Yeah! Poo rules!
