K79 Oven Build

Re: K79 Oven Build

I'm wondering about the removable door itself.

I have around 3/8 clearance all around and it goes in and out fairly easy.

Does your door actually go into your oven though? Does it protrude into your inner vent arch as the picture I've shown?

Re: K79 Oven Build

I have a reveal at the oven chamber, so no, the door does not go into the oven

Re: K79 Oven Build

Nice looking door. I'll have reveal on mine... strange that some were telling me that it had to actually go in the oven a bit. Much easier if it doesn't What did you make your door out of? SS?

Re: K79 Oven Build

Having the door both lap the outer edge and protrude will give a better seal, that is all.

Your picture is about exactly how I built my door.

Welding stainless is tricky. Do you have experience?

Also, personally I found it easier to use blanket inside the cavity than using board. You can stuff it pretty full of the blanket, and you don't have to trim bits off the edges of the board which makes nasty dust.

I have a welder / sheet metal guy that is right down the street from my office. That is pretty much what I want to do. The only difference is I was going to put some steel on the back side to. Why did you leave the board exposed on the back side of the door?

Re: K79 Oven Build

ooh ooh me! I think I know!

I think he is trying to ensure that the heat is not transmitted directly from the front surface to the back surface of the door, which would happen much more if the front and rear metal surfaces were connected.

How did I do?

Re: K79 Oven Build

I'ld say you're right, but I would think you would want to keep that cal sil board as far away from anything your going to eat as possible.

That cal sil board is very expensive. I have 3 or 4 pieces that I could fit together to fill my door so leaving the back open kind of isn't an option. Unless I used some kind of mesch to hold it in???

Re: K79 Oven Build

I wonder if you could spray the CalSil Board with High Temperature paint? I was considering doing that while my build was in progress in order to protect the board against moisture - but it did occur to me it might help stop dust flying around as well.

You would only use the door once the temperature of the oven had stabilized - not while you had a full burn going. So the highest temperature the door would see would be seven or eight hundred degrees (F) I would think? And most of the time it would experience much lower temperatures.

BW/K79,

I guess I am not seeing what you guys are seeing, DJ fully enclosed his door with a SS/CS band and back plate and welded everything closed after stuffing with CF insulation.

What did you make your door out of? SS?

It's aluminum - filled w/ loose vermiculite. I think it would help if it went into the oven a bit but I can still cook on the third day - not many are doing better than that with our type of oven. Most of the heat loss is going to be under and around the dome - insulate that well and you will be golden.

It's steel on all sides. The silver you see is just the result of grinding off my ugly welds

You're lucky to have a metal worker friend. But Stainless also costs about 5x as much for the metal

He quoted me $150 to make the door. I thought that sounded reasonable.

Re: K79 Oven Build

So I've been covering my oven with a tarp to keep it safe from the rain we've been getting up here in Maine. I read in another post NOT to cover it in a tarp and to spary it down. Can anyone verify this? I'm using HeatStop and I thought I didn't need to wet the mortar? Also can I leave the tarp over my oven?
