Stand Dimensions for 42 in Oven

Re: Stand Dimensions for 42 in Oven

John, I can't tell you if it's a good price or not, but as I remember I used bales or what ever they're called.. My batts were R19 47" by 15" if I remember correctly, but I think the extra width wouldn't have been a problem.. When you price them, make certain to check the ceramic blanket price.

Just because..

Re: Stand Dimensions for 42 in Oven

I found a listing on my local Craigslist for Mineral Wool Batts R19. They are 47" by 23". It says 800 sq ft total for $220. Is this a good deal and how many would I need. He says I can by as many as I want?

Thanks guys for your help in giving confidence to start this project. Here is step one pretty much done.

Re: Stand Dimensions for 42 in Oven

As Russell pointed out it's easy to add a half block, and if you're cutting you should find 6 by 8 by 16 inch blocks around as well. If you're uncomfortable, then unless you have some building area space limitation, size up a bit..

Re: Stand Dimensions for 42 in Oven

John,

Are you limited by space or do you just want even blocks without cutting? You can always add a 1/2 block CMU (8x8x8) into the base design (they are readily available), gives you some wiggle room and not have to add a full CMU. PS if you cutting bricks for your oven, cutting CMUs are not that much different.

Suggest you lay out a full size template. If you are planning a dog house enclosure I think you're too small.

Re: Stand Dimensions for 42 in Oven

I appreciate it guys. I feel confident enough to start digging this weekend, but still a little worried about how much I can play with as far as width and depth of the stand when I go to lay the course of concrete blocks. , if your stand is 65 in and each block is 15 5/8 in, 4 of them would add up to 62.5 in so did you just have the extra 2.5 inches made in the transitions from block to block with a little mortar in between? I'm just paranoid I make the foundation or the stand too small and then have to add to it or make the oven smaller. Or do you just cut the blocks to get it perfect? I realize I could just make the stand 8 inches to big and account for it with insulation or decorative material, but would really like your thoughts knowing you have completed the job.
Thanks,
John

Re where to buy the steel studs.. What Chip said..

Re: Stand Dimensions for 42 in Oven

And the steel stud structure? Can you reveal where I might source that? Thanks

Any lumber supply, lowes, Home Depot, Menards, etc. can supply it. It is a standard building product in commercial buildings.

Re: Stand Dimensions for 42 in Oven

Regarding the "Kit". I found that I could source what I needed closer to home and because this avoided the shipping cost of the kit, the overall cost was better. I see you're close to Boise so I'd bet that you can find most everything local. The bits you might not find are going to be the rigid insulation and the ceramic blanket. These items can be found at a foundry supply or a commercial/industrial insulation business.

The rigid insulation board is something I wouldn't compromise on. Vermicrete is fine if you have no other choice, but compared to the insulating properties of the rigid insulation, inch for inch, it doesn't compare. The cost issue has some merit but I feel that this is one of those “pay me now or pay me later” situations.

The ceramic blanket allows a tailored wrap of insulation on the dome so less air movement around the dome and therefore is better insulation than other materials. I didn't use ceramic blanket but used mineral wool bats instead. I minimized air movement around the dome by wrapping mineral wool bats around the dome and stuffing the voids with torn off bits. The manufacture of the mineral wool bats is Roxul but I'll bet there are several out there. This material is generally mandated where fiberglass is not sufficiently stable in heat. Places like backing a fireplace box is where this insulation is mandated. I found this at the White Cap commercial building supply store.

Once I finished positioning these bats, I filled the rest of the space with unlined fiberglass, attic, bats and ultimately filled the rest of the space with loose vermiculite. All of this insulation has allowed me to fire for pizza on a Saturday evening, shut the door at 10PM and come back on a Monday afternoon and find a 375F oven ready for whatever I want to do with a hot oven.

Re: Stand Dimensions for 42 in Oven

Hi Chris, I'll definitely be looking at the link, but when you refer to kit, do you mean the one from Forno Bravo? I don't see a kit that offers that size of stand. I see the Cucina series, but nothing seems to be close to our dimensions unless you modified it. The cost of the bigger kit looks to be $1050. Speaking of that, did you find there were certain things much better ordered from Forno Bravo or could you find everything elsewhere. Those 18 x 18 tiles look nice to have on the floor and the insulation on the floor and around the dome looks good to buy here. Maybe even all the fire bricks too, but what do you think. I don't see the metal stud kit you have anywhere on here.
So just to give me an idea on an example of how there are no cuts on the stand, if your stand is 65 in and each block is 15 5/8 in, 4 of them would add up to 62.5 in so did you just have the extra 2.5 in made in the transitions from block to block with a little mortar in between? I'm just paranoid I make the foundation or the stand too small and then have to add to it or make the oven smaller.
Thanks,

Re: Stand Dimensions for 42 in Oven

The stand size was fine for my oven and although it could have been bigger, functionally larger would not have added any benefit. What would be called the bottom plate of the stud wall was attached with masonry screws, found at Lowes. The kit contains a drill bit and special screws and it works well. Since the sheeting, Hardie Backer, attaches to the stand and runs up and ties to the stud wall everything tightens up nicely. When you buy your studs buy the thicker gage, the better product. The cost isn't higher but the product is less flimsy and will hold up for your great grand kids better..


I'm including a link for a thread that Brickie started, you'll find it a gold mine of tips and modifications.

Re: Stand Dimensions for 42 in Oven

Wow, I've been through the thread of your oven and those pictures really tell the story. I'm sure it's been done in so many ways, but the pictures really help a beginner. Can you tell me how the metal frame is attached to the stand? If you had it over, would you have made the stand slightly bigger to allow more room or did it matter? If possible, do you remember your stand dimensions? Sorry to latch on, but that oven is exactly what I am after.
Thank you so much,
John

Re: Stand Dimensions for 42 in Oven

The void of the exterior, 2X4, wall includes some of my dome insulation. This is the reason for the 65-67 difference. The difficulty of this configuration is really about stud placement so that you have the support structure not interfering with the insulation. I guess the thing I wanted to point out is the exterior wall and how it ultimately relates to the oven insulation.
