I'm hoping it drafts better when hot. I'm also burning smoky wood cleaning up scraps of bark and wood chips around my wood pile. Today we have a swirling wind and it's back drafting the smoke all over. Another two hour low fire this morning and that is it. I want to burn it longer but I think the two hour low burns for this week are just right.
First two fires went for two hours and the temps stayed under 200*. Oven stayed warm for at least 8 hours afterwards. Third burn went for two hours and temps were just over 200* and the oven stayed warm for at least 8 hours. The fourth burn was just over two hours long and the temps peaked hot enough to burn the soot off the dome over the fire.....so, around 700*. I let it die out from there.
It just lifts in and out. It's only used to seal the oven after the fire is out to retain heat for cooking in the oven with that retained heat....and it will keep the critters out of the oven when not in use.
You would need to insulate it with a batting. I would go 4" think. Then you could build an outer skin or structure to house it all in. An insulated steel oven will not retain heat for the long period a brick oven will but for most people that would be just fine only cooking in it while there is a fire or right after the oven has been heated up. You could go with a brick and mortar around the steel to get that heat retention element or a mixture of Cement,Perlite and Vermiculite to build up a 4" layer then insulate and skin it.tinspark wrote: ↑June 11th, 2021, 4:55 pmLooks really Good! I have been kicking one of those around too.
I have a pattern for a geodesic firepit (half soccer ball) for my CNC machine and have even been kicking around making one outa metal and just flipping it over. but I am pretty sure that I would need to coat it with something to keep the heat in better. maybe morter
I wonder if I could go light, say 16 gauge,, I am hearing that a sheet of 1/4" is over $600 right now.. was able to get em for 250 a few months ago..
personal metal projects on hold for a bit unless I can find metal for cheap at a scrap yard....
I burned my oven yesterday for a little while and I set that door on around 11 am and the temp at the door was 250*. It's 1 pm here and the upper portion of the oven is still 125* at 26 hours. I really want to get the oven hot and close it off to see how long it will hold a cooking temperature. I'm not insulated like the best one's are but mine should hold a good amount of heat for a while. Maybe tomorrow I will fire it up and get it hot then give it a try....I need to cook something though.....
Not worried about them. An oven/structure this size had to crack someplace and the fact it cracked where it did is a good thing. Inside the oven there are small cracks in a couple places and that is normal as well. Brick work expands with heat so it will crack, especially the way I built the oven with flat long walls.
A buddy of mine helped me dash coat my house. we applied a blue glue that's is made for the dash with a paint gun, then used an el-cheapo texture hopper. Mine was one of the $25 home depot gravity feed to apply the dash coat, but are actually made to apply texture to sheet rock. It came with 3 tip sizes and we used the largest tip. It has been about 1-1/2 years and still looks great. I have seen dash coat applied to block walls too. I wonder if this might have been easier?? It comes in many colors too, so it doesn't need to be painted once applied.. The grout joint would have to be flat and not concaved since teh coat is relatively thin compared to stucco..towtruck wrote: ↑October 9th, 2021, 10:08 pmI have been working on the wall around my pizza oven. I have the brown coat of stucco on and will be putting the color/top coat on soon. I had 100 square feet of surface to stucco and while I am not new to cement work I have never actually laid down stucco. I have hung so much stucco wire/lath in my youth that I never want to ever see that crap again. This was easier as I just had to prep the concrete block wall with a sealer/adhesive coat and then lay the brown coat on. I was slow and mixed 1.5 gallons of product at a time and just went slow. For the top coat I need to do it all at once to keep the color even so I will employ the wife to be my mud mixer as I apply the stucco. I'll get some pictures up once it's all done. Having the wall flat and one color really does look so much better than the dry stacked block wall alone.
