Hi all
updates to my build. Have had a very productive week.
First photo shows the stand arch completed. 2 nd photo shows the stand arch and soldier course of bricks that will also act as the form work for the hearth and insulation layer.
feed back welcome this allows for 3' of hearth and 2" insulation layer = 5 "
is this enough of each or should it be thicker.
third photo shows soldier course and reo for hearth slab.
4 th photo is the start of bench wall.
5 th photo is a close up of soldier course and reo.
Where opening is a 12" hearth will protude out from the arch way opening.

Hi Gary,
Littlehampton Bricks in the Adelaide hills

Littlehampton Clay Bricks and Pavers - Littlehampton South Australia - Character in Clay - Clay Bricks - clay pavers - manufacture and supply - how to lay pavers - paving DIY

sell a lot of their 1200˚C fired solid 4" clay pavers for oven builds, many more than their 'fire bricks'.
Check out the supplier of your intended bricks for the dome for their firing temperature, even get a brick on a hard surface and smash it once with a slrdge hammer. If it crumbles into small particles and dust, DON'T use them! If they only break into a few larger pieces, then they will be fine.

Re: aussiepizzaan getting started on 36" wfo

thanks for the info Neill ,
so what your saying is that any clay paver or brick that has been fired over the 1200*c and mets the sledge hammer test would be suitable ?
checked out Littlehampton , but distance a problem.

hi all ,
time for an update on my build.weather has slowed me up but did manage to get the hearth framed and poured.see attached photos.
The concrete hearth ended up 120 ml (4 3/4 inch ) I will put 2 inch fire board
under floor for insulation

question?
what is every ones take on the oven floor? is it better to use fire bricks 75ml thick or the fire pavers 50ml thick but with less joins in the floor .

gday aussieman lookin good!
I decided to just use the fire brick pavers and they seem to do the job perfectly.I think The only reason to use others is for the look.Also might take you a bit more time to cut them as well. here is a pic of mine hope it helps.
By the way got a nice piece of beef slow roasting in the oven as we speak, with an african spicy sauce it was marinated in overnight. The backyard smells great.
cheers

Thanks Dave
how do the pavers being thinner go for heating up retaing heat.
by the way I can smell that roast from here!!!!!

Aussie they heat up just fine and retain heat pretty well as far as I can tell.
After using the oven and the door put on, the next morning the tiles are still very hot to touch! I used 2 sheets of silica insulating board underneath them and didnt mortar them in place. They seem to expand and contract a fair bit with the heat. Also If I crack one with a pot or something, easy to replace.
Got to go get that meat out of the oven cheers,
Dave

Shouldnt that have gone under the concrete to form a larger heat mass?

Re: aussiepizzaan getting started on 36" wfo

Maybe that could have made a difference , but I think these things are over engineered as they are and I have a great working oven , and the heat doesnt make its way through the floor, so I am happy but I guess you are right, I never thought of doing it.Family just ate a side of beef that has been slow roasting for 6 hours. All the hours laying bricks was worth it for that meal! how does it not dry out? it just fell apart with a nice crispy outer surface. Did everything in my power to stop the vulcha's eating it before it was plated.
Happy cooking,
Dave

Hi Dave,
sounds like you have got your hands full keeping up all that good tucker.

I started to layout the floor and soldier course today.took longer than I thought to lay out the floor but got there in the end.
brick saw has been a great investment , made cutting the floor and soldier course a breeze.

see attached photo's

question , when I collect the fire clay do you store it wet or let it dry out ?

i am going to use home brew morter,just to make sure I have the mixture right is it 1 part fire clay, 1 part cement,1 part lime, 4 parts sand.
