Project 2005: Clay Oven

I have been toying with this idea for many years now, nearly ten I think. The crappy gas oven I've got at the moment has been the last straw. I want a real oven, an oven that can be hot as hell, or at least 350 degrees centigrade. I just have to build one myself.
This spring/summer is going to be it. I just need a place to build it and the good will of the gods. My practical/masonry skills are about as good as George Bush's ability to make a coherent point in a speech - even if he only has to read aloud.
