I'm getting closer to my Dome!

Re: I'm getting closer to my Dome!

I haven't built my oven yet but I asked the question once and had some feedback. If you want to check out the thread I will attempt to add it. http://www.fornobravo.com/forum/f8/i...ing-16044.html

Thanks and good luck with your build, if you have any questions I will be happy to direct you to someone who could answer them! Just kidding, I will do my best from the stand point of going through the build and letting you know what I did and if it worked out or not.
Again Thanks
John

Re: I'm getting closer to my Dome!

I am at the present tending towards using 4 inch. cement block

Concrete Jethro, concrete.
Anyway, concrete wont stand up to the high temps of flue gases for very long and will break down.

So I need to use bricks from the foamglas on up? I just need to be clear on this as I have no idea.
Thanks Al for the input

Clay bricks will be fine.

Hi Al,
I forgot to mention I will be using a refactory flue pipe for the actual flue. Just surrounding it with either concrete block like Dmun or brick. Brick will be at the top for appearances, as that will be the only section exposed above the roof. I said I was masonry challenged to say the least!
Thanks for the responses

It should be fine then with a liner.

I am so bad, I didn't even ask the question correctly! LOL

I do tend to skip through posts, especially really big ones and have on occasion missed information that is already written..

Re: I'm getting closer to my Dome!

Well I have put in a halogen double work light in the oven and have them on high for the preliminary curing. I hope this is actually doing something other than running up my electric bill! LOL The temp in the oven has been up to 138 degrees F for two days. It isn't enough to make steam (212F) but maybe some evaporation is being expedited? I will start my first curing fire tomorrow as it has been almost a month since I closed up the dome with the keystone. Anyone with words of wisdom? I am ALL EARS!!!!!!!!!!!!
Thanks

Re: I'm getting closer to my Dome!

There's nothing more satisfying than starting that first fire in a new oven. Congratulations!
If your dome has been closed for a month, and you've had the lights on for a while, chances are it's already drying nicely. I'd still go with small fires to start for the first couple days and build them larger over the course of a week. It would be good if you have built a door already. The more heat you can keep in overnight the better. By the end of a week you should be able to go full blast, I should think. That's the way I did it and have had no problems.

Re: I'm getting closer to my Dome!

I am working on a door as I have a little break from home owner duties and work! Hate when work gets in the way of pleasurable work!
I will tend to take it slow for two reasons: 1) I have read about the cracks others have encountered
2) more importantly - I haven't a clue on how to fix them!
Thanks

Re: I'm getting closer to my Dome!

YAHOO! First Curing Fire! No cracks, no splits, just a warm fire using some cardboard and fruit containers. It has been a month since I set my keystone in and over two week since I did my vent and flue transition. So I hope all goes well for the rest of the curing fires.
Too bad it will rain the next several days.
I'll wait till the rain stops and start on the curing path again! I'll probably start from scratch again, but to see the first fire was an awesome feeling!
Flue drafted extremely well, better than I expected, although it wasn't windy at all. So time will tell on that front.

Many thanks to all the people I stole ideas and plans from, without you all helping I would never have gotten this far! THANKS!!!!!!!!!!!!!

Re: I'm getting closer to my Dome!

Here is my door which is a bit on the heavy side from using Ipe wood. That is the down side, the up side is I think I could have used it without a steel plate on the oven side. Ipe has a fire rating of "D" equal to concrete, or so I've been told. Between the wood and steel is sandwiched foamglas, which is extremely light and an excellent insulator! I am waiting for a wrought iron handle that I ordered, and need to paint the steel. Does anyone have a suggetion for binding the side of the foamglas. A fireproof rope or something?
I just hope this door isn't too heavy in practical use!

Re: I'm getting closer to my Dome!

Started curing the oven again after the monsoons! Well it is harder than I imagined to keep a fire going at a lower temp. It just wants to burn faster and hotter than I want! Well the good news is I have finally been able to enjoy these "problems" Can't wait till the curing process is over and it's Pizza Time! I still need to tweak the door for a better fit, but overall it seems to work ok but it is on the heavy side, Oh well it will do for now. I still have insulation to put on, walls to build roof trusses to make and a cow to milk. Forgot we don't have no cows
