OK,
Here's the list of on-line resources available if you are wanting to build your own oven.
It is important to point out that there are various styles of ovens out there. I chose the barrel vault or Alan Scott style because I wanted plenty of mass to retain heat for long periods opf time.
Welcome to Wood Fired Pizza
This site is a must and provides links to many other sites. Bill Funkhouser took a lot of time and effort and it shows.
BlackOven - Wood Fired Hearth Ovens
You think I took a lot of pictures. Go to this site and click on "Wood fired oven building" and then the "North House Folk School" link. The documentation is exceptional.
Wood Fired Brick Oven Tampa
Another well documented oven build in Florida.
The Brick Bake Oven Page
A site dedicated to all types of masonry ovens. There is literally hours of reading here if you work your way through the site.
My Wood Oven - A Place For Wood Oven Lovers to Gather
A network for "Alan Scott" style oven builders to show off their stuff. Click on the Photos link at the top of the page.
Wood pizza oven Building wood burning brick bread ovens
Kiko Denzer specializes in cob style ovens, but this site has building info for all styles.
Forno Bravo Forum: The Wood-Fired Oven Community - The Pizza Oven Installation and Cooking Community
A TBN type forum that deals primarily with Pompeii style ovens. Fornobravo offers free pompeii oven plans and sells materials to support it. If you decide on a pompeii style oven, this is the place to do research and ask questions. They seem to be pro pompeii and anti everything else (go figure).
My brick oven | Sourdough Companion
This is a thread in a sourdough baker's forum I belong to. Also a well documented build.
Building a small Scott-Style Brick Oven | The Fresh Loaf
Another thread with a link to several photos of an oven build in PA.
Another place to check out is the "Brick Oven Group" at yahoo. You have to Join this board, but it is a very good place to get info and post questions. It is frequented by atleast two well known professional oven builders.
Also, if you decide on an Alan Scott style oven it is a must to to get this book, "The Bread Builders". The oven can nearly be built just using the information in this book.
That's all I can think of right now. If any more come to mind I will post them.
