Well finally more progress. Life has been in the way.

I have progressed a fair bit since the last post.

The Polystyrene Dome Former I used



Go Dome Go.



Formers for the Entrance Arch



The dome is closed in now and am working on the insulation/weather dome.

I have more photos, will post them soon - have to download them frmo the camera.

There will definately be pizza this xmas, I know Ive said that before

So I got the done Closed in Im missing some photos they are around somewhere.

This has an inch thick ceramic blanket over the dome with a double layer over the top for good measure.



Then the fun part starts, making the weather proof cover dome.



The black straps are metal pallet strapping, I got a whole roll for $9 NZD from an auction site it weighed about 80kg and is working out well for making the weather dome which is 100mm/4" off the brick.
I have used the strapping to make the little spacers and everything is riveted together. Once the shape is done Ill put mesh over it and plaster it.





I am waiting on some steel work to transition the brick into the flue after which I will be able to shape the cover over the arch.
Incase you are wondering what the little kinks in the strap are they were the best way I found to adjust the tension to try and keep the dome nice and spherical.

Oh and heres a vid of the dome internal now Ive taken the supports out.
I did this so I could see inside for the first time without crawling in there.
I have since grovelled in there on my back and cleaned it up and filled the bits I missed so its now ready for fireing.

Are you sure just an inch worth of blanket is sufficient? Or are you also planning on adding additional insulation using a cement mix of vermiculite or perlite before plastering?

Very nice build, btw...

The gap between the ceramic blanket and the plaster will be filled with Vermiculite. the insulation will be just over 100mm/4", 25mm/1" of ceramic blanket and 75mm/3" of Vermiculite.
The Plaster will form an outer shell to contain the Vermiculite which will be filled once I get the mesh on the dome.
That should be plenty.
