Well after lots of lurking on here and admiring everyone's work it was time to stop planning and get on with building. Concrete base was poured two weeks ago and work on the stand started going for a bit of a change from other builds as I had access to a lot of steel box section at the right price - free! I have got to weld in the supports for a paving flag layer then I can lay the insulation blocks and concrete ready for the hearth.More pictures to follow as the build progresses and no doubt lots of questions I will need answers to.

Hello Carl.....welcome aboard!!
A concrete slab (as apposed to the concrete base) is laid normally on top of masonry supporting walls for the dome structure to sit on. As you have built a metal base, could you not weld some angle iron struts across the top of your steel base?...this would serve the same purpose a concrete slab (it purely supports what sits on it)... you could then fire-cement a piece of 10mm fire-board on top of this and lay your under-hearth insulation (insulation blocks/vermecrete) on top of this and then lay your fire brick hearth?
Whichever route you take try to calculate your finished hearth about elbow height of the person using the oven.
Looking forward to seeing your build stages....

Thanks for the advice Terry.
Your suggestion is basically the same as I was planning to do ,only I am using paving slabs as the support for my insulation blocks.I managed to get the steel welded in today but rain stopped play prior to grinding off the welds and laying the paving flags.

Hi All Finished my base and now I am ready to order firebricks etc from kilnlinings. I have worked out the bricks required and I think I need 140 for the hearth and dome (900mm) plus two bags of fireclay does this sound ok to other people who have much more experience than me or do I need to increase my order. Thanks in advance Carl Attachments:

depends on the size of your oven, for example my oven is 32" diameter and used about 1.5 bags of fireclay. I used reclaimed red bricks for the dome and fire bricks for the hearth and entrance so i cant remember in total how many i used.
Just remember its best to order more than you need rather than realising afterwards and needing to order more and pay postage etc

Hello Carl, my oven is 772mm internal diameter an I used 130 fire bricks. This includes an oven floor where I used more bricks than necessary as I did not cut them to fit the shape of the dome. I'll attach a pic that hopefully shows what I mean. Robin Attachments:

I would agree that 140 bricks and 2 bags of fire-clay will be enough for an oven up to 90 or so centimetres(internal diameter).....as long as you lay your fire-bricks "on flat" for the hearth.

Finally got some decent weather so I have cut all my bricks for the oven hearth.Just need to get a couple of bags of lime to make up the homebrew and I am ready to start setting the hearth in place and building the dome .I still have to decide whether to use formers or a radius tool to constuct the dome!  |

hi Carl, the build is looking really good.nice work with the hearth.its nice to get to the technical stuff.it's like going from a butcher to a surgeon after all the blockwork  those numbers on the firebricks will be invaluable when setting them down.I had a photo on my phone to help me piece then together.I also found placing two batons either side of the hearth location and using these to drag a length of wood across to level the homebrew the easiest way along with lots of patience and a rubber mallet haha. |

Carl I love the nice neat cutting of your fire-brick hearth. I always use forms for building the dome, but in all honest I think the central jig is a far better way building the dome. If you want advice on anything...keep shouting out. The "search" button at the top of the home page is also a good way of finding if any topics have been covered on the forum...simply type in a couple of key words. I also use this build... picasaweb.google.com/115426447285405371194/WoodFiredOven ...very often for reference. Terry |
