@ mickeytap yes I will include a chimney, I just haven't built that bit yet. I dont know whether having a chimney affects the heat retention, I cant think how it would to be honest as it is outside the door to the dome. Cheers Pete, I'm finding it hard going but its gonna be worth it

A quick dry layout of the outer arch this morning, and a cheeky small curing fire - sweet! I can almost taste the pizza

HI Mick,
I cannot speak for h12rpo but in general for pompeii ovens the chimney is located in an arch outside the main oven door (which in this build you can see above). The reason is then if you want to do retained heat cooking you can place a door in and that will seal the oven totally and the chimney will not affect it.
I hope that makes sense, if you search here for door you might see a few folks have made and that might explain it better.

You've done it again.....similar to my build...except better!!!....I love it.
I really like the time and effort you are putting into this build.

h12rpo, turkey Thanks for your answers that makes perfect sense. I'm just researching at the mo and have been looking at a portugese ready built jobby. They come with or without flues, I think the one the flue, it's in the middle doesn't hold the heat as well and I'm assuming therefore would be better for longer cooking. I wish I was a confident as you guys in picking up the trowel, but a man needs to know his limitations! Thanks again

Here's the dry lay out of the decorative arch. Here's a failed attempt at cutting a vent for the chimney....I thought I'd do the same trick as earlier and make it out of celcon/thermalite block using a dirty great masonry hole cutter which I have, but no matter how I tried to visualise it, it wouldn't fit into the arch/vent transition area: I had a ponder over a couple of pints and another way to do it struck me so a pic showing how I did the hole/vent ....This is a practice piece with basically different depth cuts with the saw and then give it a sharp tap and all the bits fall out - result! And one showing the two vent bricks in place: And finally here's one of the arch mortared up and looking good (if I do say so myself); and the whole thing:

Looks very good if you ask me, cutting the flue hole and making it all sit together in an arch is quite tricky to get your head round when trying to put it all together. Looks like you cracked it

.....yep. Totally agree.....Beautiful job. This time you have taken a totally different direction as to how I create a vent in the external arch. (I hope you don't mind me "comparing"...as I am learning a lot from your build. I lay 2 bricks either side of the "spring point" then lay 1/4 bricks to the rear and 1/2 or 1/3 bricks to the front creating an oblong vent, hopefully equal to a 5" circular vent)
I won't say your method is better than mine....as I'm fed up of saying that.....just to say....I'm looking forward to your next installment.

Terry, you learning anything from my first attempt at all this malarky is very encouraging, I wouldnt hold myself up as any kind of expert......all the knowledge and skills necessary for this build has been researched from this forum. It's all here if anyone wants it. Sure there are a few mistakes and some 'it's close enough' moments, but thats probably true of any amateur build. Next challenge is the verm and rendering which I just know is not going to be plain sailing

Hmmm ...the vermecrete is anything but....plain sailing. I hate the stuff and would love to find a substitute for this (important) thermal layer. I tend to add an equal quantity of hydrated lime to the vermecrete as this helps it bind together well....especially for the first part of the dome covering....wear some marigold gloves if you use lime as this stuff is not friendly to the skin when wet.
You're still building and I'm....still learning.

Try my curved trowel idea! Work out your finished radius for the Vermicrete, and mark it onto a section of timber. Cut out the shape and then fix a section of 1/8" ply to it. Make the whole thing about the size of a normal plastering trowel. This then used as a gauge to hold back the Vermicrete whilst tamping from above, and working in layers, building up the sides of the dome. The radius helps to eye it all in. I also made a rotating jig from the Top Dead Centre of the dome too. The curved trowel idea also works fabulously for the rendering once its applied for the finishing float. You just need a slightly bigger radius.

Yep, thats the plan.......bookemdannos trowel seems like the way forward. I must admit I fancied doing one of those formers fixed at top centre, like they form bell molds, but I couldnt work out how on earth I could ascertain where that is on the dome ??

I initially rescued 'Fred' shown below from a skip thinking I'd use him for a former for the last few chains........................However, he turned out to be the wrong diameter entirely and so I stabbed him to try to take the smile off his face......It didnt work! ;D
