Re: Hansen Horno
Thanks Dick. No, I didn't put any HeatStop on the inside (except whatever shows between the dome bricks, of course). I did put some on the outside, maybe 1/4 inch thick, and there were several long cracks in that (and in the mortar lines). I was worried they would appear on the inside as well, but I can't see them so far. Actually, I should probably stop looking, because I'm sure I'll find something wrong the more I look! Better to just ignore it.

Re: Hansen Horno
Hansen,
Looking good. Did you put HS on the top inside of your dome??? I did that (thinking that I won't the next time) but haven't had any issuess.
Don't worry - cracks happen. Call it character.

Re: Hansen Horno
Here's a pic of the oven with 3' chimney attached. It draws fairly well, but I'll definitely need to position the decorative outer arch a bit lower than my outer oven arch, because plenty of smoke is escaping out the front right now.
Got it up to about 750-800 degrees tonight! Just beginning to clear the soot off the dome. No cracking evident on the inside ... yet.

Re: Hansen Horno
ooh, let me know how it works out. I think it's a great idea. Not as sure about the maple front (although it's lovely, I'd hate for it to burn up!) but the durock covering the insulation might work. I've been trying to figure out the door thing too- I've been using board covered in heavy duty aluminum foil, and the insulated door really makes a difference in heat retention, and tipping it backward and elevating the bottom a bit while I'm firing (to get the air whooshing in) works great too. Much better than leaving it open while firing.

Re: Hansen Horno
Here's my attempt at a DIY door. I used a piece of 2" insulation board sandwiched between a thick slab of maple and some Durock cement board. I used some hi-temp fireplace sealant to seal and secure the side, top, and bottom pieces of Durock, which are not screwed down like the back. Then I painted the Durock with hi-temp grill paint. I still need to add some fireplace gasket rope where the wood touches the brick. We'll see if that keeps the wood from burning up!
This door might be next week's firewood, but I figured it was worth a shot. Total cost = $35.

Re: Hansen Horno
Thanks Les and Elizabeth! After running a 500+ degree fire for 8 hours on Sunday, I wrapped it all up with the blanket. In retrospect I should have put the chimney on for the day, 'cause it sure did get black on the front!
To take advantage of the heat, I baked some naan (Indian flatbread) for supper. It turned out great!

Re: Hansen Horno
This is my 3rd curing fire, and one of the cracks I discovered after the first fire. I think I probably went too hot with the first 2 fires, though I did only use newspaper. There are several cracks around the outside top of the dome, possibly because the fire was concentrated in the middle of the oven. The cracks are long but pretty small, so no concern at this point.
EDIT: I should have mentioned that the grey stuff with the crack in it is a layer of HeatStop covering the top half of my dome. I never posted a pic of that. The cracks start there and travel down mortar joints to my soldier course, in at least 2 places.Last edited by dbhansen; 09-11-2008, 08:02 PM.

Re: Hansen Horno
Here are pics of my chimney base plate and arch buttresses. I attached the plate with tapcon screws, and put a layer of insulation blanket in between the plate and brick.
Not sure if I needed the buttresses, but they'll be completely covered with my enclosure and they add a bit of insurance.

Re: Hansen Horno
Sorry, Darren, for high-jacking your thread with photos of my kids! I got carried away.
While I'm high-jacking, though, Happy Birthday Frances!!
