Cheers for the comments, I think I'll do without the board.
Turkey - do you have any details of the EBay supplier? I have done a search but can't find anything that looks similar.
Cheers.

myworld.ebay.co.uk/mickyg001I found Micheal very helpful, even when I wanted some solid plate at one side as I was replacing a missing BBQ grill Etc. They had not done it before but where more than happy to make it as per my dimensions. If you have a specific idea / size I would just contact them and ask and see if they can help.

Wow! Just seen this build (not checked the pompeii forum for too long! ) Amazing build and will be a dream setup! Can't wait to see the finished thing and I'll be following this build eagerly as like mine you've gone for brick oven + bbq + work space although you seem to be progressing at approximately 90000x the pace I have! (I'm jealous I wish I had a few spare weeks to spend on my oven again ) Keep up the inspiring work!

Hey thanks for the comments Duncan! It's been a quiet couple of weekends, I have only managed a small amount of brickwork (arches) and very little else. I am off work Thursday through to next Tuesday, so I hope to be able to make loads of progress then. One comment I'd like to make is how good the communications from Kiln Linings were. I ordered online on Thursday morning, had a confirmation phone call later the same day and the delivery arrived yesterday. And the 10% discount from the forum was nice too One question about homebrew mortar. I am planning on using the 1 : 3 : 1 : 1 mix of OPC, sand, lime & fire clay. Is the sand builders sand (soft sand) or is sharp sand better? I am wondering if the clay content of builders sand would cause a problem with expansion or degradation at high temperatures. There are also fancy grades of sand like fine plasterers sand and the like which may be good for a mortar, but I haven't seen anyone make a reference to using that sort of material. What has everyone used?

Hi I'm just using building sand with no problems so far.

building sand here, makes a nice smooth sticky mortar. If dry the bricks really suck moisture from the bricks so I would pre wet any bricks before placing.
my mortar seems to crack when used for large areas so I did just the bricks and waited till later to skim round the dome to make a smooth finish ready for insulation. Really seems to grab well tho.

Looking good - For the hearth insulation I agree with Terry - thermolite blocks - They are a nice easy and cheap way of doubling up the insulation in this area - keep in mind you want maximum insulation wherever you can. For sand I used 'mixed' sand - only because I had bags of the stuff lying around. 2 bags of fireclay did my 41"

Now, if i'm right a little sharp sand could help avoid the cracking due to the irregular "sharper" particles binding together but if its too sharp you lose the ability to create fine joints in the bricks. Its a trade off. The larger joint would benefit from sharp sand, but it hinders the fine joint due to the larger particles. However sand does differ from county to county. For renders use Plastering Sand, which is a mix of washed soft and sharp sand. I'm planning to use Hydraulic Lime and a 50:50 mix of soft and sharp sand for my brickwork.

Finally started on the construction of the oven itself yesterday. Hearth bricks laid out and marked up. Hearth marked out - I dry laid the cut bricks on the hearth then used spray paint to mark the outline. (I only broke one of the bricks - if you look carefully you can see it ) Hearth bricks mortared in place and some of the soldier course in place. The soldiers are storage heater bricks cut lengthways with the thick end placed to the inside of the oven. Soldier course completed and quarry tiles fitted over the hearth bricks. I bedded the tiles on a very wet mix of fireclay/lime/sand/cement and then pushed a slurry in to the small gaps between the tiles using my fingers. Now I just need to get my head round exactly how to do start the oven arch off - I can lay the bricks in a couple of different ways and I need to have a bit of a play around today to figure out what is the best way, especially as these bricks will take quite a lot of weight from the dome.

And finally, the reason why I hadn't been able to make much progress recently

Nice progress Faz.......what did you use to cut through those storage heater fire-bricks?
Love the car......do you race them?

Hi Terry,
If you look at the first pic above you can just see a Partner 2 stroke disc cutter. I've got a diamond disc on it and it really does make cutting the firebrick (and the blocks for the stand, rebar and everything else!) much easier than using a grinder. I'd go as far as recommending people buy a secondhand one and then sell it on again when they have finished their build - they hold their value pretty well so you can probably do a complete build and sell it on afterwards and maybe only lose 20 or 30 quid at the most.
The car is a Ministox which is raced by my stepson (age 12). He had a bit of a crash and I need to do some rpairs to the engine but that's racing!!

for the start of the dome I would work out the general plan, ie what bricks in what orientation so you can calculate (or guess timate) the angle from the soldier bricks to the first bricks on he dome.
then you can cut small triangular bricks and create an angle right on the soldier bricks to make a firm transition to the soldier bricks.
