Re: Justin Pompeii
I have now finished the insulation then attached inner and outer chimney flu and front veneer bricks. So now i need to render the dome with coloured concrete render and float the top slab up the level of top of floor bricks. I lit the first fire yesterday and nothing cracked or exploded, even at 100-150Deg C for about 1 hour.

Re: Justin Pompeii
Sorry i havnt posted any updates for a while. So i will summarise what ive been up to for the last couple of weeks
I finished the dome and covered the main dome part with 2 layers of insulating blanket, the inner one was about 1 inch (25mm) thick and the outer is about 1/2 inch (12mm) thick with a thick aluminum coating. I layered these on the dome and sealed the joins with aluminum tape, this way the insulating concrete liquid will not seep into the blanket
I then boxed up around the base of the dome ready for insulating concrete, for this i used a product called Shiralite.Last edited by Justin; 12-29-2008, 03:05 AM.

Re: Justin Pompeii
Belive me, Christo, I wanted to take them out about 10 minutes after the Keystone was in place. Dad (who at 62 is somewhat less excitable than I) made us wait a whole day. It was agony. Now I'm glad he did, but at that point I had to go home to keep from touching it.

Re: Justin Pompeii
Great advice.
My arch collapse was likely a result of me removing the forms way too early.
The oven looks great - you are really close now.
Any special plans for the keystone?

Re: Justin Pompeii
Don't worry, the rest of us have been there, too. Just keep the forms in until everything is dry. Looking good!

Re: Justin Pompeii
Thanks guys for the tip about the arch form, at the moment there is about a 3mm gap all around it so should be OK. For future courses i will use a shim as suggested as they will need to rest on the form.
And yes i will need to start another project once this is done to burn off the extra pizza calories!

Re: Justin Pompeii
Please, that's a total nightmare and nothing I want to think about while I have a form under my arch during the cure process. Great progress!

Re: Justin Pompeii
Good point karl, I remember after getting my form "just right"...it was about 3/16" too short, or so I thought; I remember thinking "damn it, I have to make another". For whatever reason, I did the smart thing and used shims to get it up to the right height. Just pulled out the shims the next day and out came the form. I can see someone's form becoming wedged in there, then beating it out with a mallet - cracking all of the mortar or even knocking the arch down.
