Re: Cast your own
Sorry, I didn't mean to be flip. We have had some scattered experience with cast ovens. One that comes to mind is member Ed Schmidt in Michigan. He cast geodesic triangles, and got much better results that I did by cutting them out of rectanguar bricks.
Others have proposed making sector based ovens, and even casting entire ovens using something called a dogloo (a hard foam doghouse) as a form, but to my knowledge, they haven't come back to talk about it.
I think the deciding factor is the time factor. It takes so long to cure inches thick refractory castings, when in fact most builders have trouble waiting that week before starting the curing fires. If this doesn't bother you, then there is no problem, particularly if you can get affordable castible refractory material.
So, by all means, go ahead, and please keep us posted. We learn by what people learn, and share, in the course of their projects.
