Yesterday was a good day to make decisions. Beautiful weather at last, with no urgent obligations pending. Some decisions were already made; corner build, 42inch interior, 20 inch door, FB board, FB morter, solders laid flat, the transition following the lead of Doug, John, Sharky and ggoose, with a nod to the Field Furnace guys in Australia, and with the system of cutting the bricks in three cuts at 5 degrees described by jcg 31, as well as seriously considering using the airspace idea between dome and the vent and chimney as innovated by drseward in his Colorado Oven. Then, the other decision still not made; Naples style or Tuscan style. OK I succumbed! Compromise style. [I'm sure someone can come up with a better name] I split the difference between 21 and 15.5, or about 18 inches for the dome, and 63% for the height of the entry, or about 11 inches, and am planning to going with that. By the way, why 63% why not 60 or 65? The other factor would be the area of the opening which would vary by the shape. And, I still don't know how to post photos with this text. It asks for an URL which I've been unable to find in my photo gallery.
