Good evening, I started building an oven a year ago, it was gong to be oak framed and on castors so I could truck it out of the way on the patio. Once I totted up the weight of the wood I was using I realised I was going to exceed the 1.5 tons that the castors would support, and anyway manoeuvring it behind the apple tree was going to be difficult. That meant that it had to be put somewhere permanently, and I would need to nibble a bit away from one of my wife , Helens's flower border........ End of build.However a new bathroom , toilet suite, (actually two) promise of a new car,redecorating, etc etc. and I've now got permission !!! This approx 1m squared of real estate makes central London look cheap. Anyway here's the frame and castors that I originally built. It took ages to cut through the oak sleepers with a hand saw. With permission granted I dug the hole for the foundation and then filled it with 750 kg of concrete mixed by hand.

A friend of mine is a stone mason and I asked him if he'd put a Portland stone plinth on top of the concrete- most of it would be hidden and I know that this is not sensible, but I can't help it. He couldn't come so last Saturday I botched it on myself.I've never used an angle grinder before, hell of a kick, need to be careful.It was chucking it down with rain and as I've taken the week off to start this build and with an awful forecast I went to Argos to get a waterproof gazebo Meanwhile whilst waiting for my friends arrival , and as my son was home form uni we started cutting some firebricks and the thermolite blocks and cut an arch last week when it was sunny . any way I'm in our pub next door and battery is about to run out , hopefully with the next post I'll get up to date and will be live with the construction. Cheers RockDok

First off great start Rockdok. Seems a shame not to use the oak frame constructed, looked neat.
I like the arch with shaped bricks which I am debating myself to either cut or leave straight. Keep posting the photos
Cheers
Pete

Thanks Pete, I reassembled te oak frame on top of the stone, so am still using it, just took the castors off. Hers a pic of it in situ - I'm just screwing the oak sleepers which form the top to the Next the Thermalite blocks- these were very easy to cut -I over egged the pudding using a reciprocating saw- it was intact easier just using an old saw blade and cutting by hand, holding the blade with a glove. I used one of these mixers from lidl- it is certainly very quick and I was glad of it mixing the mortar to put the Portland on. I used this method to get the angles on the arch- piece of string at the centre of the former I've taken the week off to kick start the build, and this was yesterday using the simplest possible version of the indispensable tool to get the orientation of the soldier course correct And finally here's where I'd got up to last night Although I used gloves , they weren't waterproof so I've got a few sores on my hands form the lime. Just been down town to get some heavy duty marigolds. Got up at about 3.30 am yesterday to see the Morris Dancing on the Cerne Giant and welcome in the dawn of the first day of summer, Helen was working a late shift and didn't get back till 1 am this morning, and to be honest it was going through my head how to cut the bricks for the next course. There is the spreadsheet on the FB forum, but I think I'm going to use the piece of string from the centre of the oven floor to give me the angles. May just do a bit this afternoon. Cheers Paul

Paul We are in the process of putting a set of plans together for a "standard" Pompeii build.....unfortunately they will not be ready until late summer, which doesn't help you much! You can pick up tips from forum members but best way to help with your build is to delve into the archives of our members previous builds. A lot of members have fully shown their build with stage comments and photos of each stage. A very useful way of finding something is to use the "search" facility (at the top of each page)...type in a keyword and it will show all the posts that have discussed the topic/keyword. I use a form myself in building the dome... ukwoodfiredovenforum.proboards.com/thread/677/terrys-2nd-build-robs-oven ....others use a central pivitol jig....or "dispesible tool" as often referred to... plus.google.com/photos/105964699085980237524/albums/5839914686309680209?banner=pwa The bricks can be cut in a "trapazoid" fashion angling each side so the morter joint stays the same...I take the easy option and use full halves with lots of refractory mortar (homebrew) in the joints. If you want to cut the bricks with an angle grinder, then, soak them in water first. They're much easier to cut and will save the life of your masonry blade. Terry

Paul I like your simple but effective central Rod?.....at the moment you will have no problem in getting your bricks to take that initial "grab" before laying the next. The further you go up, the central pivitol jig...or "indispensable tool" comes into it's own as the L bracket on the end of the jig allows you to rest the brick on the L bracket until it has set. I've only used a dome form myself so I must get round to trying a jig. Is that saw a normal chop saw with a masonry blade or is it special for bricks?....I like it. I want one!! Thank-you for asking about posting multiple pics. I've just purchased more storage space for using the "add attachment" feature for uploading images. I've also installed a new plug-in which is the "add image to post" at top left of page (when posting). There is also the insert image icon.. plus you can copy and paste the direct IMG when using photobucket. Only the "add attachment" facility takes up storage space from the forum..... In any case we tend to bully people to post pics so please carry on as you're doing. A post does read a lot better when there are only 3 or 4 pics per post. Terry

Nice solution with the string - but dont get too hung up about accuracy of the brickwork - so long as its neat inside the dome so brick edges dont start to collect soot , you can get away with a lot with the HB mortar.
Looking really good !
All the best PeteC

Thanks for your kind comments Terry & Pete C. Terry it's a piece of string and not a rod, but I took your advice and made an IT using a T-Hinge that I had. The saw is an evolution mitre saw with single bevel which I bought from screwfix when they were heavily discounted las year- the blade is a diamond blade from the same manufacturer that I got off ebay. It works well the blade is 255mm diameter - so it'll cut with a single sweep if a firebrick laid flat but on it's side it won't cut right through so you've got a bit of manoeuvring and quite a few more cuts to do to make the taper, hence my somewhat slow progress. PeteC thanks for your reassurance about the brickwork- I've relied heavily on the HB mortar where on the inside of the oven where the soldier course meets the upright bricks of the arch ... I hope it doesn't crack in use. BTW is the LP in your avatar a Jimmie Page reissue ?? Heres the progress so far - back to the grindstone now cheers Paul.

Superb work Paul, very neat brickwork. Like the staggered joints on the rings something i am trying to achieve. At this rate you will be overtaking me? as i was hoping to top out today/tomorrow. Pete

Thanks Pete, don't think I'll be overtaking you- been helping my daughter with her biology revision so it'll be a late start today. Heres where I got up to yesterday It's interesting how as you progress it gets a bit quicker and easier. On this last ring I put a 5 degree bevel on one side of each brick so get a tighter fit and to eliminate the inverted 'v' gap . the pic below shows three cut bricks the one on the right has a 5 degree bevel cut on it so it's a tighter fit than the bricks on the left where I've not cut the bevel. The next pic shows the saw set up with a 8 degree mitre which produces the wedge so that the outer part of the brick is wider than the inner, and the bevel is simultaneously set at 5 degrees . I have just got my head around this...... I think and will have to sacrifice a brick or two to get the angles right by trial and error for the next course. Bio revision has finished until this evening so I'm looking forward to getting cracking. PS spot the chicken. Cheers Paul.

Fantastic! That oak frame would be perfect for my primo ! Might I ask you for the plans ? We are hopefully moving to west Dorset in the next couple of months. Just waiting on the sale of our French house.

Great progress Paul, still admire your perfect cuts which makes the assembly so much easier and quicker. Did you intend to alternate the brick colours or a happy accident, looks good. How are you planning to finish the dome, render or brick?
Keep posting the progress
Pete

I remember someone with a name begnning with B mentioned that last year... Glad to see that it works for full fire bricks, i never got round to that. Good work! Well Done.
