This is going to come across a bit weird. I look at some of your ovens and I am genuinely in awe. Amazing craftsmanship, budget, and materials. I don't have any of those. My clay bricks are from the neighbours garden, the firebricks were donated to me, and as a result I've spent about 40quid over the year I've been building it (yes, I gave up after 2 arch falls last summer). Anyway, the pics....  PICT0003 by Jimer, on Flickr Laying out the base. The front firebricks were cemented down, but the rest just sit on sand.  2014-09-02 16.11.48 by Jimer, on Flickr To cut a long story short, it took 3 attempts at an arch before I realised I really had to cut some bricks. This has ended up weird because we didn't measure anything. It is nice and solid though  We were only going to do the arch, but then went mental, rushed, and ended up with this...  2014-09-02 16.11.26 by Jimer, on Flickr Coke bottle for the chimney for now.  2014-09-03 09.38.24 by Jimer, on Flickr  2014-09-03 09.38.35 by Jimer, on Flickr What do you think ? Don't worry, I'm not precious about it, but I think it might actually do the job! Tonight, a question about the next stage on from this....  2014-09-03 09.38.14 by Jimer, on Flickr |

G'day
Recon that's a pretty good looking oven. They have that certain feel about them when they are homemade from the materials you find about you.
Coupler things that might help.
That chimney hole is a but higher than the entrance which from my internet chair seems to be about 2/3 of the hight of the inside dome. 2/3 the height means it should breath and operate pretty efficiently through the main entrance anyway just like they have done for the last thousand years . That chimney might be a waste of heat being higher. Might want to block it off.
Might want to insulate that dome it will get pretty hot otherwise. And of course waste you time and wood getting and keeping it hot. Easy and cheap is pearlite or vermiculite mixed with Portland cement at about 1 cement 8 pearlite/ vermiculite. You apply it in handfuls patted into position . Render over to waterproof.
Again nice job
Regards dave

Thanks for the info Dave, good to know I'm not too far from the mark! That's interesting about the chimney, I could really do with losing it anyway - reading the problems about mounting them and the expansion ruining any finish. Don't you just get a load of smoke in your face though? I wanted to put something over the dome before insulation, maybe just some more mortar/bits of brick to sure up the gaps. Do you think this is worth it, or will a vermiculite layer give it some strength too? Now Vermiculite - would anything be wrong with buying the bags meant for potting plants? www.diy.com/nav/garden/garden-care-watering/compost-sand-bark/specialist_compost/Verve-Vermiculite-10L-10288076 |

Yes. It'll cost you about 5 times as much as it would from Jewsons  You should be able to get a 100litre bag (I ended up using about 5-7 bags if I remember correctly) for around £12-15 by quoting the discount code in the Jewsons section. |

P.S. I accept our builds are worlds apart in terms of budget and materials, that being said I still really do like what you've done and how you've gone about it. Keep up the great work!

I think it looks great! Budget builds are the best - really rewarding.
Dave has said exactly what I thought about the chimney. Fill it in. Yes you will get smoke out the front when you fire her up but this soon dies down when you are getting up the temp range - say 20 mins ish and maybe when you add more wood but nothing to worry about.
I would add a bit more mortar if you are concerned. The vermicrete won't really add any strength.
Cheers
Andy

G'day
I've a friend that has an oven with an internal chimney. He blocks it off to save on wood and the smoke comes out the front. . I've shared heaps of meals from that oven and it works well my preference is to an external chimney.
You dome is strong because it is a dome and gravity makes it strong. The mortar just orientates the bricks so a layer on the outside is good to keep the bricks in position.

Something like that, yeap, but I used a lot under the hearth, and all around the dome, + loose backfill for my behemoth.

Well, my local Jewsons were happy to help and use that account for the vermiculite. 25 quid + Vat for 2 bags.
Thanks for the heads up, 'tis what forums are all about!

That oven is brilliant I like a recycled oven on a budget(I recycled firebricks,all metalwork,granite,and paving slabs)
