Rocket mass heater project: experienced help needed!

Hi ! I have been dreaming of building a RMH since we recently moved to our new place last spring.With winter on the door step I am ready for it!Unfortunately our 4 month baby hasn't given me the space to do much beyond reading the book and downloading some of Ernie&Erica's plans.. Anybody in Melbourne (Bend of islands,3097) with successful experience in building one and willing to help ?

Thanks,

thierry.
