I should have said that for the base, I also rendered. But this time I used weber pral M sourced from Jewson. More expensive (£15 a bag) but better colour availability.

Thanks for info guys, will be looking to get some waterproof layer on next week and probably give this render a go.
Paul, you may be right about the length of flue although I have seen short and long chimney versions. Although I'm burning some pallet wood for the curing fires it does seem to smoke quite a bit until the flames take hold. I may have to extend the chimney to gain more draw but I will continue the small fires burning for now.
All the best
Pete

Build nearing completion now. I have applied 2 coats of K-Rend with the surface wire brushed to smooth out the finish (thanks for the pointers alun) Available in any colour as long as its 'butterscotch' from the local builders merchants. Would have preferred a darker colour but its growing on me and piece of cake to apply, bought 5 bags and used 4. Applied some sandstone paving to the plinth today which gave the angle grinder its final workout for this build as each had to be shape cut. This just leaves a chimney flue extension to be added and door to be fabricated. Cheers Pete

Really nice looking finish on your dome. I haven't yet used K-rend but intend doing so on my current build. Must look back over Aluns thread/advice as I'd like to get a finish similar to your's Pete.

Thx Terry, I'm no plasterer so pleasantly surprised at the finish I achieved using the K-Rend. Really does enhance the finish and also gives a good key between layers to 'rough-up' the surface with a scratch float if you have one or failing that a wire brush as I used. Thx for your support Terry and creating a forum which allows mere mortals to produce a WFO. Next photos I hope to show the first pizza..........! Cheers Pete

Pete that really is stunning. I think it's amazing what you can create if you really put your heart and mind into something. I bet that your first pizza will be the most delicious thing to have passed your lips ! You did ask on another thread about chimneys. I followed some advice from mikey1968 and got mine from machine mart. He mortared in a flue connector, so he can take the flue on and off as he wishes. Total agreement with your comments about Terry. I wouldn't be doing this without this forum. cheers Paul

Thx Paul, yes the flue connector looks like a good idea and I have a slab on the chimney (for rain protection just now) I can mortar as a base for the connector.
Had a good fire going in the dome last night and looking to next weekend for the grand opening event! Still not too sure how to cook in the embers and move them aside but that is the fun part to enjoy now the build is finished(ish).
Cheers
Pete

I've just finished the vermecrete layer on my current build and If I get a finish half as good as your's..I'll be happy.
Forno Bravo have had their own set of full plans for a Pompeii build for many years now. I am half-way through a set of drawings for a Pompeii (with the help of "ibrick" ) and hope to have our own full set of plans by later this year. One of the hundreds of titbits will be to explain how to create a barrier between the final render and a "hot" chimney. This is a weakness and may cause cracking at that point. I will suggest putting a 12mm piece of plastic against a chimney stack when laying the final render coat up to a hot chimney. Once a crust has formed on the render the plastic...or piece of timber can be gently slid out leaving a 12mm gap around the chimney. This can then be filled with fire-proof mastic.
I know it's a bit "after the horse has bolted" to mention this but keep an eye on that area when fully firing your oven.

Terry,
I did wonder if I should have left a thermal break at the chimney for the render coat as its the only point the top coat should be in contact with a hot surface. I will keep an eye on that area and if I need to retrofit I can chop a section away and pack with some Calsil or thermo block and re render to that.
Cheers
Pete

Pete I love the chimney and I am hoping or a similar look with my build. Apart from the issue terry has mentioned is there anything else to watch for with the brick chimney. I think most obviously the weight concerns me. Did you wing it, or was there method behind the design of it? Thanks Delaine

Delaine,
Would be great to say weeks of planning and drawings went into the build but to be perfectly honest as you have guessed I winged it! The build evolved during the 4 weeks construction.
The weight shouldn't be too much of a concern as this is supported by the arch form, although a good buttress for the arch is required to give strength.
Cheers
Pete

Looks really great Pete. I'm pretty happy with the way the K-Rend turned out on mine and yours looks even better. After rendering the base as well though there isn't much left of my wire brush!
Sorry to say but my dome has a couple of cracks on it, almost certainly as a result of the render butting up against the firebricks. Terry's advice about adding a 12mm break should be a must for future renderers.

That is a shame Alun and sounds like its probably on the cards for mine at some point.
Cooked my first pizza last night and have to say it DID taste good, no pics unfortunately as it didn't stick around long enough! Had the fire going for a good few hours and although the temp on the floor was around 350C the soot didn't vanish from the roof as I was expecting?
Cheers
Pete

I've been meaning to post about a similar experience. I'm yet to have my dome completely clear even though I'm getting high temps on the floor and retaining heat for days.
