Hello again! 
Well, I'm sending a photo of my creation. Hoping that it will be a success and I'm so anxious to make pizza, etc. I'm about to cover the insulation, I made the dome with castable cement and fire brick following the ebook available through Forno Bravo. I read so much about people using a layer of vermiculite and then stucco. I have heated the oven several times with increasingly hot fires. I ended up with 2 small hairline cracks toward the back of the dome (outside). Then I put on 3 layers of blanket ceramic insulation. Then chicken wire and will put on 2 layers of stucco with a small escape valve in the back of the dome. Pretty basic! Its a 42 incher with 2 in board insulation below. The chimney is abt 45 in tall, 8 in dia flue liner to get above the cedar pergola. Can I have a decent oven like this? I dont really seem to have room for a layer of vermiculite concrete as is planned. There is not enough of a ledge to support it. Also, is the stucco by itself going to seal moisture out well enough? Ive read about acrylic additives, etc. As you can see, I built opposing counters, its poured cement, exposed aggregate. Did most of it myself. Gas grill on right and fire pit on left along with sink and fridge. Could use some expert last minute help! Thanks!!

You can pretty much put the acrylic on top of anything. When I was working with it, it reminded me of sand in latex paint. And it DOES work. After quite a few years I am seeing a little chipping at the base - I may re-coat the base in a few years when it looks like it may get to the hearth. I personally would avoid using wood for the door. I know there has been success but we have also seen failure. If you can swing it, go for an insulated door, or at a minimum, go with a simple steel plate (what FB gives you w/ their ovens).
