You could eliminate those little cuts on the sides by moving the bricks over to one side by 1/2 a brick.
Noticed your entrance is deep. It's just about the same as mine I find it usable, for a dome. You could make it wider and higher otherwise that back wall is going to appear a long way from the front.
Hope something here helps

I am interested in those brick as well. They are apparently insulating brick, but I have never seen that type before. How much do they weigh?

Hi Polo,
If I was to take a guess,around a kilogram?,
possibly less.

Hi David,
Yep, those are the insulating bricks.They are actually seconds which came out of the boral refractory but in very good condition & @ $2 a pop.They are 230x170x75.
Karangi dude was the one who put me onto them.

Wow, that is a lot of thermal mass in the floor, or are those insulating firebricks between the supporting slab and the floor bricks?

Re: Alan Scott oven in sydney

Its been a few days but got some materials now and so today i did a mockup to see how things will look.
Laid a course of bricks on the outer edge to hold the insulation bricks in.
Thanks once again to Karangi dude for putting me onto these.Quite cheap also.

I did a quick layout out of the oven,allowing 125mm of insulation where needed all around.Set out where the 3 respective arches will go.Didnt really know where to stop with the insulation bricks at the front but i think i will end them with the inner arch and same with the hearth bricks.Also i intend on putting some sort of membrane between the hearth slab and insulation bricks,maybe foil or a plastic layer.

The hearth floor put at 45 degres means i will have very small cuts on 2 sides.
Hopefully building the oven walls on these edges won't pose any problems.

Re: Alan Scott oven in sydney

Fair point. Guess you are saying just put the insulation on top and given the weight is spread over a reasonable area it will be ok?

You can start building the oven within 1 day after the slab is poured.

I have seen carpenters start the frame 1 day after a pour, not something I would recommend as there is no strength in the concrete to hold the fasteners.

Re: Alan Scott oven in sydney

How long did you leave between pouring your hearth slab and taking the form work away and being ready to move to the next stage.

Why cant you just keep on with the progress and just leave the form work in place?

Re: Alan Scott oven in sydney

This is true,there's always a silver lining
But i wont lie,once you start at this, the hankering for the finish line pizza is something no grown man can resist

Gudday
Sometime that timeline slips a lot. Took about 7 weeks till the first pizza
......and three years till completion

Rain that's good! That slab will cure well in the damp and be good and strong. Drying out only takes away its strength .

Hi John

Looking good!

How long did you leave between pouring your hearth slab and taking the form work away and being ready to move to the next stage. I'm thinking of taking a few days off to kick start the process, however there is no point if I'm going to have to just sit and wait for the slab to dry?

I guess there could be some point in that I could sit and drink beer and dream of the pizzas I plan to make.

Cheers

Mark

G'day Mark,

I know what you mean.Most people wait for the hearth slab to cure for a week but ive seen some on here take to the next step straight away as well.I might wait some where in between like 3-4 days.Having said that, rain has started here in sydney and predicted for all week
So far i only took off the formwork from the sides of the slab.I think i'll leave the formwork supporting the weight for a little longer.

In the meantime i can order materials and find some weather protection for the oven build.

Cheers John

Re: Alan Scott oven in sydney

Sounds like you are making the right choice for yourself. I only commented so you could get the real life numbers from someone who has nad uses a higher mass oven.

In the end you need to build something that is suitable to your needs and not someone elses. Good luck on your build

Thanks Polo,
I agree with you.Here i was thinking pizza oven designs were pretty much universal. Only when you get into understanding it all,you find out how minor changes can alter an overall characteristics.

Well today we poured the hearth slab.
We put a second layer steel mesh in as we poured the concrete to give it more tensile strength.Slowly making progress.
