    Re: 82cm Corner Underway in Bulgaria

    Many Thanks David for the reassurance,

    With regard to question 2, I was trying to understand if the 3 stacked bricks you can see on the picture have been cut (albeit roughly ) to accommodate the oven wall and to start the arch. Do these bricks keep the same shape as they go over to form the arch or do they need to be cut more straighter after a certain height.
    I apologise if I'm not clear and misunderstood your helpful advice.

    ANOTHER QUESTION PLEASE ! I have seen posts where a support needs to be built for the entry arches.

    Is this normal? will the arch and tunnel entry way NOT stand on its own?
    I see many pictures where supports have not been built, so Im a little worried and confused.
    My back aches today with all the bending and cutting yesterday, so Im taking a break but will need to go and buy my fire cement.
    With regard to such I see mention of the home brew.
    I can buy here bags of ready mixed sand and lime, it is kept damp in plastic bags and is usually used for pointing work and such like.

    Question 2 Can I use the fire cement on its own only adding water.
    Question 3 If I use the home brew I would have to use the fire cement and the ready mixed Lime and mortar. Does this still constitute the home brew?
    Question 4 I've read that Im not supposed to allow the insulation board to become wet, but worry that it must come into contact with the cement at some point thereby making it damp, am I unduly worrying on this point.?

    This is a big, BIG project for me to undertake and money is an issue and so I ask so many silly questions as to alleviate my worries and to pick the brains of you who are much more qualified than I.

    Thank you Mr Chipster for your comment about the wall, It is dry stacked and hope that at any point it doesn't collapse on my oven We are prone to earth tremors in this part of the world being only about 6 hours from Istanbul where the experts reckon the next Big earth quake will be, if it happens in my time and my wall and house falls down I want my oven intact just to show the locals that an Englishman Can build a sturdy construction.
    Once again thank you

    That stone wall in the background is amazing. Btw the answers you got from David S are spot on as his answers always are...

    AS you can see by the pictures the cutting leaves a lot to be desired, this was my second attempt too.

    Question 1 Do I fill the gap between the floor and first course with cement OR do I leave it to fill with ash?

    On the other picture shows the cut brick which will form the arch entry

    Question 2 Do I keep this shape all the way up and round to where the arch will meet OR is there a point where I change the shape, for example,to a half brick?

    You can also see on one of the pickies that my reveal will be nearly 1 1/2 inches, this made it easier to accommodate a full width brick for the front arch.

    The floor bricks were, in my opinion expensive. I did purchase second hand bricks for the dome etc but I have found that there are various widths, depths and lengths.

    Question 3. If my bricks are varying heights on the sailor/soldier course would I be able to overcome this unevenness on the second course, possibly by compensating with more cement underneath.

    If anyone sees any potential problem that may be lurking ahead with my build so far then I would appreciate any comments. Good or bad !

    I, like you and all others, have trawled these boards and picture galleries, and everyone seems to have their own slight variation possibly to overcome little problems that have come up, hopefully my little niggles can be sorted too.
    Many Thanks in advance for all your replies.
    1. Leave a small gap. One thickness of corrugated cardboard should be sufficient. Pull it out or let it burn away.
    2.normally you keep the same curve using an IT. You will need to trim the bricks more the higher up you go because the radius gets smaller the closer you get to the top.
    3. Slight variation in brick height will be accommodated by the mortar joints. If it's lots you will have to trim the bricks. If you don't have a saw a 5" angle grinder with a diamond blade works pretty well.A 4" one doesn't give you enough depth of cut.

    Brick Hearth Layout.

    Taking advice, I put hand in wallet and bought new bricks for the floor they are 25cm x 12.5 x 6.5cm

    They were 3.90 leva which equates to approx. ?1.73p in UK sterling

    I have adopted the herring bone pattern like many others and found it was very simple more than I anticipated. Because it is a corner build I lay my bricks from the side /horizontal/vertical therefor the HB was achieved looking from the front.

    Here are a few picks to where I am at the moment.

    My Bulgarian language skills leaves a lot to be desired and insulation and other materials are difficult to source or not available, particulary quality. IMO.

    Not being able to be understood properly as to my needs from willing locals I have ordered my insulation from the Uk. 12m of insulation blanket and 2 pieces of 1000mm x 1200mm x50mm ceramic fibre board.

    I am still awaiting the delivery of such maybe the end of June so I am on the hunt for a good stone brick cutter.

    I have see on the internet the HF saw and looks great but I cannot justify the cost of shipping one over here.
    Their are many variations of tile cutters but none I have seen will go through the bricks in one pass, I did see one for 1800leva (approx. ?800) and they did hire them for ?20 per day but as I will need it for a long period I shall opt for the large angle grinder with diamond blades which will be my cheapest and best option for making cleaner cuts.

    I have managed to purchase used firebricks for the dome, 60 stotinkis each (26p)
    I have given them a good clean up and when I cut them in half I shall use the cut face towards the interior.

    WORRY QUESTION As expected the edges are very chipped, do you think its a good idea to go with used FB.? Do they have a life expectancy? Will they still perform as good?

    One of the photos from the side view shows the pencil line where I shall cut the front bricks to straighten the front edge landing.
    Is it feasible to cut little bits off this size.

    82cm Corner Underway in Bulgaria

    Many Thanks to those on this forum who give those of us lesser mortals like myself with no building knowhow a guiding hand.

    I have so far picked many a brain just to get to the stage I am at now and no doubt will need more guidance as I travel the daunting path to Pizzadom.

    Anyway like those who have led the way before I will upload pictures of my efforts along the way.

    Here are a few showing the slab and hearth.
    It is 140cmx140cm with a bit chopped off the front where the oven will face.

    Thanks to Nissan Neill who drew a few sketches to show how my layout would look, unfortunately I made a bit of error on the wood storage opening, but for me it didn't matter so much as I have approx. 18cu m of chopped wood in my barn next to the oven area.

    However for those who may read this and not yet at this stage, think very carefully about your stand/slab size it may limit you later on.

    I wasn't sure of the depth of the stoned area in my barn hence a slab of 10cm.
    I also had time and a truck load of gravel so I filled in every core for the support.
Working...
