It's been a while since I have had a chance to work on the oven but made some progress over the weekend

I bedded down the floor in the end as I had to much of a height variance between bricks and that helped with getting the floor as flat as possible.

I also placed a slight angle towards the front of the chimney landing in case any rain ever came in so this would not enter into the oven. The actual dome cooking surface is perfectly level

after placing the soldier coarse in place I was not to happy with the size of the external gap between bricks so I tapered every second soldier by 7mm total of around 15mm off each brick. This has halved the external gap.

I also shaped the 1st arch brick which was not as hard as I expected so I will try to cut some more next weekend.

I have a question around whether to glue down the Soldier coarse to the insulation bricks. What are the pros and cons of doing this? I do not have an issue of leveling it out with hight temp mortar but rather what is best practice?

I built my dome on top of the firebrick floor, I used a very slight layer of mortar under the brick, My joints werent as tight as yours though,

My thought, All bricks in the oven will move due to heat and expansion, some evenly, some not. Im sure I have cracks inside the oven I cant see,, It is unavoidable, as I see on many builds we have put a fefmix or heat stop render over the dome.. so what im sayin, is its all good whether you do it or not is more a matter of personal choice....I Think either way would be fine, and dont forget that the dome also holds bricks in place by compression as well as render/refmix.. As well when you vermicrete the dome you are basically cementing the bricks in place even further,, Hope I have cleared this up some, rather than confused you

I just set mine on the insulation board. Gravity holds it in place. Mortaring it to the insulation won't help anything.

It's looking good John!

I hope that the rain showers stayed away for you on the weekend so you could build without interuption. In Newcastle It looked threatening all Sunday morning with a few light showers.

Hi Mark/Joe,

Thanks for the advice. I guess if there is no reason why not to bed it in I might just wip up a slury of high temp mortar and just place it on top. Better more tham less I say!!

I will set this this Saturday unless someone can tell me otherwise

Thanks for the info again guys.
