Hi everyone, i have started mt first build, no experience so bit of a learning curve.... I have cast the foundations. Inside diameter of the oven will be 80cm, and making from storage heater bricks. cut the hearth and now just awaiting the arrival of blocks and building materials for the base. Hopefully this will start this weekend.

Looks very similar to my project, 90 cm but similar layout. I have put my project on hold following shoulder surgery so will watch you progress with interest Good luck

G'day From the mock up I see the entrance and the oven mouth are the same size. To get an oven door to seal you could make the entrance a bit bigger leaving the oven mouth with an inch or so clearance. This lip or revel will enable you to fit a airtight insulated door in the future and you can then use all that heat in the bricks for baking and roasting. Keep the pics coming Regards dave

Hi Dave, yeah was planning to do this so thanks for the heads up. Just mocking up the possible entrance landing with standard size heater bricks. The built entrance will (hopefully) have a 20mm lip for the oven door to butt up to when closed and retain the heat. Door design is in my mind, but as you can see a long way til I get there!
Thanks for the comments, this site is great for learning and overcoming problems, even before you have got them!

Hi, I have heard of people using short chopped pieces of fibreglass or carbon fibre in the mix for the cement mix. As I can get some, I wondered if it would be beneficial in the home brew and also for the render coats (possible also with the vermiculite?) to stop any or reduce shrinkage?
Anyone heard of this technique? Would it benefit the build?
Any thoughts appreciated....... Thanks

G'day Yes the councils use a type of fibre in concrete paths cheaper than steel and stops cracking. If we're in a WFO at temps of would destroy it I suspect. Anyway the mortar is there to act as a gasket between the brick units. Keeps them apart rather than together (And yes when building the dome for a while it does act to keep them together.) It keeps the bricks in correct orientation to form a dome. The domes shape the strong bit. As the dome goes from low temps to 500C and the cools back again it expands and contracts with the brick keeping the show together. If it was ultra strong it would probably crack the bricks. You can get cracks, they happen but the mortar will keep the bricks in the dome form. So being extra strong is no advantage being the correct strenght is. A render layer of home fire cement 12 to 25 mm is better for the strengh of you dome than adding anything to the mix Regards dave

So had a really good progress day today. Very happy and tired. Finished the base and lintels. Then put on the flags and thermalites. Then laid the hearth on a mix of homebrew...man that is sticky stuff! Finally got got the arch, soldier course and first course of storage heater block laid down. Time for wine now!!!!!! Just trying to work out how to get the pictures the right way up!,

HA cheers Rivergirl.... Sorted it! After another successful day in the garden, (thank you weather for holding out!!) I have now managed another 3 courses. Family day for the bank holiday, so no more building. ill leave it to cure out for a week til next weekend, when hopefully the dome will be finished! Thanks all for sharing your experiences, it has made everything a lot quicker and somewhat easier to progress at a pace !
