Re: Sydney Construction Has Started!!
With one of the wettest summers I can remember in Sydney, I wouldnt be surprised if water has managed to soak into the oven.

Re: Sydney Construction Has Started!!
Sounds like your oven is wet. It takes a lot of energy to push out the water. Just continue to fire slowly and it will dry out and fire as good as it used to.

Re: Sydney Construction Has Started!!
Hey guys I will post this in another section as well but after a successful first few years I am finding it increasingly hard to get the dome and floor up to temp? Fired for 2hrs today and the dome only got to 180 degrees?.???

Your guess as to when it will happen is a good as mine, it may take ages.Last edited by brickie in oz; 01-23-2011, 02:44 PM.

The span was about 1.5 m, but it shows how well cut pieces will stand the test of time, earthquakes, siege, weather etc.

David,
Thanks for sharing. Obviously, there is some significant buttress mass on either side of this arch. Do you recall the approximate arch of the span?

[QUOTE=JD07;106430]I am finding the thermometer is only reaching loww 100 degree celcius??? QUOTE]
Where is the thermometer located and are you checking the temp with the door closed?
I assume you dont have thermocouples in the floor and walls to check the stored heat?
The floor temp should be much higher than the air temp and if the baking tray is directly on the floor it would conduct this higher temp.
Another option is to leave some coals in there.

I have noticed one thing though, I made a sandwich construction door for the oven with 1500 degree fire blanket in between the 3 mm plate. However if I build a big fire for a few hours and then sweep out the coals and embers I am finding the thermometer is only reaching loww 100 degree celcius??? The walls are 200% or so but the internal temp will not raise over 120. It retains temp well with the temp the next morning only dropping 30*. However I would like to do a full lamb and have already made the tray but I need 160 min for 4 hrs to do a whole beast. I dont want to undercook it, 180 for 3 hrs would be better.
Is there a trick to firing the oven and getting the heat into the refractory bricks??

All about arches, load distribution, support, etc.

Its a very good read.

Re: Sydney Construction Has Started!!
Just wondering on line - how many arch failures has the forum members witnessed??

Re: Sydney Construction Has Started!!
i tend to agree with brickie even though its an arch theres a heap off weight in there without sideways support for the arch at the base in saying that...
it looks great and it wont be hard to fix up later on
