And the completed outer arch with the first layer of bricks to support the chimney base.

Re: Hansen Horno
I think five weeks should be fine - to be honest, you could bake pizzas in a cured but uncovered oven. The heatstop wouldn't take long to cure - less than a week probably.
I've read that curing can be done as a continual process - rather than cycling the oven, put the door on to hold the heat and gradually raise it each day.

Re: Hansen Horno
Question: Let's say I get my chimney done by next weekend (really pushing it). Would it be reasonable to answer "yes" to my son's request to have a birthday pizza party about 5 weeks later? I have no idea how long the curing process will take. Can I reasonably expect to be baking 6 weeks from now?
For the dome insulation, I plan to use a blanket insulation and loose vermiculite, so no curing there. I am thinking of coating the dome with my remaining bag of HeatStop, though, to add some thermal mass (maybe 1/2"). That would add some curing time.

Re: Hansen Horno
Thanks for the feedback guys! Much appreciated. As I told my wife, I'm basically satisfied with the way it turned out, but I'm saving perfection for my NEXT oven (when I'm retired and have more time on my hands).
I just realized that I have a flower on my dome, thanks to the unfortunate aligning of two mortar joints forming the stem. They don't align on the inside, though, so maybe it won't be an issue.

Re: Hansen Horno
I was lucky that my failure to cut a proper final course gave me a great selection of brick odds and ends to use!

Re: Hansen Horno
Daren,
I agree! The dome looks incredible! Perfect symmetry. Looks like you've been doing this for years!

I just started with a small square of brick and slowly cut more and more off until it fit!

Re: Hansen Horno
And here is my start on the outer arch. Not sure how I'll be completing it yet. I definitely think I'll need some kind of buttressing on the outside of the arch walls. I'm thinking of doubling-up the wall thickness by adding a stack of bricks, or perhaps a perpendicular stack of bricks. Or maybe just a steel "L" bracket of some sort. I'm open to suggestions!
The walls look really thin from this angle, but they're actually a full brick width where they butt up to the inner arch and they taper down a bit at the outside edge.Last edited by dbhansen; 08-17-2008, 09:07 PM.

Re: Hansen Horno
Dome is complete! The first 2 pics are outside, the third is from the inside. A little choppy, but I'm satisfied with it. In hindsight, I should have crafted a better form to help guide the final courses into place, because it was too easy to misplace the bricks. Final inside height is 20.5 inches; 1/2 inch shy of my plan.

Re: Hansen Horno
Another good weekend of progress. Here are some pics as I completed the dome. The rod/wire sticking out on the first 2 pics is a thermocouple probe.
Still limping on that foot, but it's getting better! I only needed the crutches for one day.
