I am possibly 3 rings from closing the dome and need to do the entry arch and think I will use 25kg of powdered fire clay. I have not skimmed the outside in mix so if you planned to do that perhaps it might go over the 25kg but probably won't. That 25 of fireclay ends up with 150kg of homebrew. It is scary how much the oven will end up weighing.

Thanks For that I was thinking the same you tend to think about the weight of the bricks and forget about 150kg of home brew plus 200kg of concrete

If i'm going to bed the floor on a dry bed of clay and sand would a mix of 1:1 be ok ?

That should be fine. The mix ratio is not particularly important, its only real purpose is to provide a permanent flexible surface to allow the creation of a flat floor given the relatively small variations in brick thickness of firebricks.

Used a 1:1 fire clay to sand mix for the floor. Then started on the dome using the home brew recipe 3:1:1:1 sand:fire clay:Lime:cement Attachments:

For some reason the forum is displaying my photos sideways sorry for the neckache. That was where I finished yesterday about three rows high. Attachments:

I um'd and arr'd about how to finish the arch. In the end I laid the top brick sideways and used it as a keystone. Attachments:

fiddly work cutting angles on the back of the arch bricks but will help laying the row above Attachments:

a long day on angle grinding, and having faith in the homebrew. I'm still not sure how the bricks were held by the mortar.The top ones are so upright but given a few minutes I could move the support away. I keystoned the top of the dome, was pretty tricky lots of trying cutting, trying again. I'm pleased with the result in the end just got to point the inside and then start on the chimney/entrance Attachments:

I can't believe it, not only have you managed to keep the dome in line with the indespencible tool, but also manage to top out in one day and its only your first build!!! amazing work How did you deal with / find the arch to dome transition?

Great progress.....like the way you closed the dome. When you re-point the interior try to plug any small empty perps you see and make the old mortar as smooth as poss....it'll stop any ash build up.
