I took a day off and got on with it yesterday, figured out the transition of arch to chimney and started the insulations layers. Overall, I am pretty happy with the progress and how I managed to get the transition done. Just hope the chimney draws the smoke up and out.

This pic shows the angle iron flattened out on the sides to give support to both sides of the blocks that form the roof over the entrance. You can also see the thermal break going across the front of the oven giving enough space underneath to act as a rebate for the door. Plus I used additional pieces of fireboard to cover the front of the oven where the chimney will join the front wall of the oven. Attachments:

To ensure I got a nice aesthetic from the blocks at the entrance, I ran the angle grinder through the blocks about 20mm behind the font edge so the angle iron effectively acts as an invisible lintel. Attachments:

Thermal blanket and wire in place on the body of the oven. I had some extra Calc Sil board that I put at the back of the oven (Thanks to the idea of Moonhead!). Plus I had a couple of off-cuts that I put over the ridge of the oven for double thickness. I secured the wire with some upholstery nails that I had kicking about, nailing them directly into the double strength thermalite around the base of the oven - worked a treat. Attachments:

Final pic shows the tapered section of the chimney. I put the cast iron bar across as mentioned to try and see if I can hot smoke in the chimney but in the end it was vital to support the blocks while the homebrew dried off. I cut a groove in the blocks that hold the bar and then made sure that it is reasonably loose and I can even remove it later if its not required. Any comments / thoughts / suggestions are much appreciated Cheers JAS Attachments:

I love the look of this, the use of storage heater bricks and the way you've overcome the little issues that using them has brought up! Very well done! I was worried at first when i saw your entrance arch brickwork, but tracking back through i saw the clever use of the angle and rebate cut into the bricks! Nice! I like that sort of thing!
The raw brick oven shot reminds me of the big military hangers over near Bedford.
Well done, you should be cooking before too long. Maybe get the Turkey in there?

Thanks Danno,
I got the Devils Porridge on over the weekend using some shuttering to speed things up, all 400 litres of it. It really is not nice to work with!
But I am happy to say this project is now looking like an oven and so glad to get the Vermicrete on ahead of the frosty weather that is forecast for this week. Pictures to follow.
Just need to get the chimney sorted and then for the render.....
First curing fire will be lit tonight. Cannot wait to see if the chimney works.
You read my mind about the turkey!
Very, very excited.

Jas, you seem to have leapt forward with yours, well done. I'm very interested to see how you build your chimney up. Mine will be a gradual taper I think, with a mixture of stone on the front and bricks around the back. don't know when it'll be though with the predicted weather... If I wait long enough I can see how you get on with your smoking bar before committing to mine

Jas, it will be a brave man to cook the Christmas Turkey. I think I'd be hung drawn and quartered. That said.... Na better not!
Really interesting build you've got there. The chimneys not the chore it can seem. You've done the hard part in getting the vault up. After that point my chimney evolved around the rest of my work on the entrance. Looking forward to more. Cheers Rick

Rick - thanks for the feedback, I think your oven is outstanding, very well done indeed. I am not worried (now) about the chimney but the transition was hard to get right. The solution I have come up with is simple enough but it takes a simple chap like me a long time to come up with the perfectly obvious, while extending my vocabulary at the same time! Dave - you may have to wait rather a long time to find out if the smoking bar works! This pic shows the font blocks of the chimney cut to maintain the taper. Attachments:

This pic is taken from above the chimney looking down. hmmmmm.... not quite square, but I guess it will not be seen once the outside is finished and rendered. Attachments:

The Devils Porridge application is a stage I am quite happy to be in the past. I was gobsmacked by quite how much water went into the mix to get it right. It is going to need a helluva lot of drying out before the render goes on. Attachments:

I simply had to include this picture, the chimney does draw the smoke up and out!!! This was taken when it was dark so its not that clear but it does actually work. Yeehah. Attachments:
