Yours? Where did you get the (cast iron?) inserts from?
I really really want to build a pizza oven in my back garden, but a) it's tiny, and b) my missus isn't keen until the nippers are a little bit older - she has visions of hideous injuries.
I'll reply properly when back in civilisation and not on mobile but that one I posted is awful. I know other folks who have built from scratch and they are miles better.
