Re: oven stand size
You mentioned facing the liner with the used brick. I had a wet saw, so cutting the face brick was no problem. I cut my brick leaving a 2" face. This left about a 2" gap betwen the liner and the face brick which was filled with 10 to 1 vecrete.
The ss pipe shown at the top is just where I inserted a transition piece should I have wanted to extend the chimney with a section of double wall pipe. The face brick on my chimney are 3 brick X 3 brick (24"X24"). The 8" OD flu liner that you have would only require 2 brick X 2 brick (16"X16") if done this way. That is, if you decide to use them.

Re: oven stand size
Yeah I'm always a little leary of used things. These do seem to be in good condition and we're only used in the chimney for 2 years. I'm not married to the idea of using them just thought that they might be easier to install and face with brick. But yes they have been stored outside since 2012 and have been through several freeze/that cycles.

My main consern would be their condition, since they are used. Also, have they been stored out in the weather since they were removed? I'm thinking of them getting wet and how freeze/thaw might effect them. I'm not sure that it would

Re: oven stand size
Yeah it's pretty crazy prices up here... We used to have tons of clay Manufacturers here but they have all closed down so everything has shipping costs added into it. When I bought my CFB the shipping would have been more than the product itself. Luckily I had someone drive it down for me.

Re: oven stand size
Ouch! That is high. I had two choices for firebrick on my oven. One was a pressed firebrick that was very close to perfect. I used those for the floor. Another, cheaper option, was a wire cut firebrick that I used for the dome. The wire cut were not as perfect in symmetry as the pressed. But, I figured since they would be mostly cuts, what the "hey" .
I know that John (GianniFoccacia) would think this "a blasphemy", as my dome was not built from the most perfect of cuts . But, the old gal is holding up so far .

Re: oven stand size
I did a couple of years ago and it was about 2.68 per brick but havent gotten updated pricing. I was also going to check with another supplier and see what their pricing is like on both bricks and mortar.
I think ive finally settled on building a 36" oven since I have to pour new concrete anyways, just need to confirm the number of bricks that will be needed then get my plan drawn up and get spousal approval to proceed.
As for that clay brick it does have some chips in a few bricks but I agree it will look good as vaneer face brick.

Sorry, for the late reply. I was working a lot of hours this week. My answers are based on a deep flu entry. A brick and a half allows plenty of room for an 8" flu. You may not need that large of a flu for a 36". Surely not, for the 32". But, there are plenty of builders out there with the first hand experience to comment on that .

Originally posted by thebigt View PostI live in the bald prairies so wood is available but I have to buy it...a 1/2cord of split birch runs about $180-200. Would there be much of a difference in fuel between a 32" &36"?
Part of the decision on will be based on how much room I have in the location where I put the base as I prefer it to not stick too far out into the yard but again probably a pretty small difference between 32 and 36. How much extra space would be required for a small enclosure if I go down that route?
For an enclosure, I would go for 3" of ceramic fiber blanket. And / or, as much loose fill vermiculte or perlite that I could aquire or afford.
A 36' oven: Will be 36" ID, of course. 36"
Add 4" for the brick X 2 for each side. 8"
Add 3" of insulation X 2 for each side. 6"
Add 3.5" for metal studs X 2 for each side. 7"
That is 57 " minimum, for the width. You can cheat in a little, if you are careful with the stud placement.
The depth, will depend on those figures + how deep of an entry that you decide. There are thinner metal studs available, but I don't know if they are OK for exterior builds. I work with wood. Had, I have went with a dog house (I meant enclosure ), I would have split treated studs on the table saw for framing.

Originally posted by Gulf View PostI think that there are several ovens on this site that have built 42" ovens with just one box (six pieces of 1' x 3') of CalSil. You don't need the CalSil under the flu entry. But, I think there will still be enough from the cuts to include that area.
I just want to add to what has already been advised to deciding oven size. That is fuel (wood) availability. One reason that I built a large oven is because I have plenty of wood resources. I don't know much about your area. From the single pic that I have of your oven stand, I don't see much. From what I have read about your great country, ya'll have a lot .
