Got a bit more done today. Slow going. The brick cutter, who is also the client on this build, insisted we knock off for Filipino pork skewers and stir fry noodles for lunch, then we had to go get more lime, and Southwark, then our other mates turned up so we had to review progress.
Got another course of bricks laid and some cut for the next course tomorrow.

My mate tried a butane torch on the corner of an off-cut of Hebel about 8 by 8 by 6 inches. The surface was glowing red where the flame was impinging on it, but an inch or so away the block was still cool to the touch. After allowing the surface to cool, I found the surface was no more friable or powdery than the area that hadn't been heated to red heat.
Three minutes with a torch is hardly a scientific test, but pretty impressive just the same.
I seem to remember seeing advertisements where they did the same thing, back when this stuff was first being introduced to Australia.
I reckon it is a viable material for insulation under an oven.

How's it going working with someone else on an oven?
I built mine all by myself just taking my sweet own time about it an enjoyed the experience and Queensland great winter wheather.
Working with someone else was a different experience but enjoyable none the less. I made it very clear that it was His oven and He called the shots and would only say something if was truly drastic or dangerous.
We certainly didn't do the work of two men and drank too many beers but the oven got finished and we both enjoyed the journey.
The oven works well and is different to mine ( pavers and pearlcrete!)
I enjoyed that build as well as my own, I enjoyed the company and the beers. An as a side note... Both our wife's still talk to us both, so alls good.
Regards dave

It is a buzz, Dave.
Lots of interested friends drop in to see how it's going and they all require an explanation and guided tour. We do not want for supplies, tools, moral support, constructive criticism, or assistance.
For example, today I felt the concrete slab under the oven spanned too big a gap. I really felt it should be braced in the middle before we added anymore weight. The committee discussed it and decided to humour me. So one of our mates expertly welded a brace, and I mean the sort of welds I can only dream of laying, while we continued to cut and lay bricks.
One tough bit: the oven needs to be the right height to operate from his entertaining area, which is about 2 feet above ground level, so the stand is over 5 feet high from ground level. Working off ladders and stuff does add an extra dimension.

The beer is plentiful.
My mate is married to a lovely Filipina, SWMBO, and he loves the Filipino lifestyle. Which is, it seems to me, a continuous party.
Actually, it seems to be based on gatherings of family and friends to share food, music and laughs
At this time of year, the festive season, we are welcome just about any time. We are not complete freeloaders, we all try to ensure the fridge doesn't run out.

The food is another story, I believe the man is on a mission to convert all of us to Filipino food, and help me gain a few kilos along the way.

My tale is similar to yours with regard to the work. I hold out for a good fit when the bricks are cut, and I mix the mortar and lay them. Once the dome and entry arch are built, the rest is up to my mate.
We'll do whatever he wants, though I do try to restrain anything I think dangerous, or just won't work or endure.

I reckon we've done more in 6 days than I did in 6 weeks on my own.
Got another course done today.
Two courses and a keystone to go, we estimate. I go back to work on Monday and he has to take the missus out on Sunday. I'm keen to leave him a finished dome, so we really have to perform tomorrow.

Of course, he is in Rotary with my boss, so there is a possibility he'll just ring him up and demand my services for an extra day.

WOW
Oven building by committee .... Now that's a concept I had never considered?
Must be interesting.... Keeping a bunch on track ... With beer involved... Southward is not a iffy beer either

The committee is well stocked with men who run their own one and two man contracting shows. No output, no pay, so these guys like to make a decision and get on with it.
Very Interesting.
Southwark is right up there with vegemite.
If you were raised on it, you like it. Otherwise it's "How on earth can you stand that crap?"

Never gets a good review, unless it's a South Aussie writing it.
Southwark Bitter

Funny thing is, lots of reviewers say its a substitute for VB, whereas most guys I know won't touch VB.

Got most of it done today.
No beer and supplies run interfering today.
Did a full ring and 4 out of the 11 bricks we estimate we need in the final ring.
Turns out the film She Who Must be Obeyed wants to see (requires a 110 mile round trip to go to the cinema in Port Augusta) is not on til Tuesday. So we are allowed to finish the dome tomorrow.
7 or 8 bricks in the final course, and a keystone.
8 days to build the dome.
We gotta get it done. She Who Must Be Obeyed fired up this morning, about all his unfinished projects.

By lunch time all was forgiven and SWMBO made us chicken curry and rice for lunch.

Looks likme the committee approach works .

But the oven will be unfinished if you start the cooking process prior to final render if that what you are doing. Seems most stop the build once they can fire oven up and cook.

So true. I've been telling the committee that there is a way to go from here.
We got the keystone(s) in this afternoon and sat down to have a stubby and discuss the next steps. I've been telling my mate that the next step I'd like to do is coat the outside of the completed dome with a layer of lime rich reinforced render to beef up the thermal mass and tie everything together.
The whole committee can't see the need, because, not having been fired to 4-500 C, this thing is currently as solid as a rock.
Of course, I'm saying that it will be subjected to tremendous stresses, and any help we can give it, we should.
He plans to build the enclosure from hebel block, so the whole house is one big block of insulation.
Next step is to build the front entry/smoke chamber/chimney.
That is going to be an adventure.
My mate would very much like to see the chimney run back over the dome and rise from the centre of the oven, a la Neapolitan pizza ovens.
I've been trying to figure how we would do that, since the ones I have seen have a brick lined channel.
The thing is, that isn't really insulated, which doesn't matter for a Neapolitan pizza oven, but surely must for a retained heat baking oven?
He can't see why the channel up over the dome can't be made from Hebel, but, despite my faith in the stuff, it is reasonably fragile compared to brick and I have my doubts about long term direct exposure to combustion gases.
More decisions.

Tell them I said it [Hebel] cracks if in direct contact with heat. It insulates very well my hearth under full firing does not get above 48c at its base. I am using a scrap piece of hebel panel [ which is reinforced whereas block isn't ]for a temp door and it has cracked severely,

Not sure I get it, he wont add extra thermal mass has, thin walls any way, but wants to run the flue back up to the middle of the dome from the landing. That adds nothing to the oven in any way but provides an indirect path for flue gases to travel. Hmmmmmm interesting....

Is he going to use blanket around the dome?

You can get flexible flue that will follow the path of the landing to the dome I believe have seen it in my own research
