      Re: cobblerdaves build

      Hi All
      Progress to date on sealing this oven Great... and is successfull. Oven remins dry even though we have had a least one good shower of rain a week.
      Arch complete so the hearth now has overhead cover from the rain and any drips from the edge fall outside the oven. The entrance is deaper than what you would normally find but I have a rectangle dome entrance and tending the oven is no problem. I do have the advantage of an extra large entrance which let you lite an ambient fire to sit in front of once the eatings over and just talk and watch the flames... priceless...
      Brickwork has been cleaned down with vinegar and finally pressure sprayed to remove the last of the lime scum, Then it has been given 2 coats of "Bondall"
      sealer to prevent the old bricks from soaking up any moisture. This has darkened the brick slightly not in a bad way...best way to put it ..inhanced the colour.
      Yes I have thought of inclosing the whole oven at times ..but really I like the dome look. As long as you take measure such as sealing the dome render with a sealer and the entrance is covered you shouldn't have any problems.
      The main difference is that I used old bricks which were not as water resistant as you would hope. The bondall sealer has solved that and I like the look that the mix of different colours and texture has given the oven. By the way some of the bricks in sections come from an old church and 1 I had for years as a door stop came from an old pub.

                  The virmiculite was expensive though. I used 60 kgs at around $6 a kg. I think I should have used 120 kgs though. How many kgs did you use in your build?

                  My oven cost me around $1200 in total to build.

                    60 kg's that sounds like a lot of insulation

                      No I didn't use vercimulite or pearlite in my build. I used ceramic insulation which from memory cost me A$170. It gave me 2 in over the dome which I finished with 4 in of rockwool. From memory I think it would have taken me 2 to 3 bags of pealite at $35 a bag. The exta cost was well worth it as it gave me dry insulation which considering the wet wheather we were to have have and it was an outside build I was lucky. The pearlite cement would never had dried for months.
                      My build cost me about $1200 about double my original budget. The big expense was a 175 firebrick at $3.30 ea the ceramic insulation fireclay cement lime sand and cement. All the tools I had already had, a cement mixer I borrowed ,the blocks or the base was free except for 15 I had to buy same with the steel and the brick for the external parts.h
                      So all in all I concider myself blessed especially considering the results. It's not the flashiest oven but has proven to be solid and certainly cooks better than I could have hoped.

                        I read the virmiculite layer should be about 4 inches thick. My virmicultie layer is only 2 inches thick, so I either got the ratio between virmiculite and cement wrong, or I should have used double the amount of virmiculite.

                        Seems to work ok though. I haven't actually fired it above 600 degrees yet though.

                        Cheers

                          right that's a lot of light weight insulation you have there Shane?Usually for dome insulation the mix is 1 Portland cement to 8 insulation. What was your mix?
                          Frm memory I had planed to use 3x 100 ltr bags f pearlite that's .001 mtr2 for ever ltr so 1/3 mtr2 to cover the ceramic layer of a 1 mtr dome with 30 mm roughly.

                            My mix was wrong then I guess. I think it was about one bag of cement for each 10 kg of virmiculite. The virmiculite I purchased game in 1kg bags and were about 30cm X 20cm X 15cm deep.

                            Anyway seems to hold the heat ok.

                            Think all of the moisture is gone as well, as the cracks are easing up, and there is no longer any water patches around the cracks either.

                              Always been meaning to buttress the side of my entrance but like most things that work you never get around to it. I also admired Jamie Oliver's oven with its brick dome. Zene oven came along ...beautiful ... Love the old brick. Then Vwiz covered his stand with old brick cut in 1/2 like a veneer! I thought to myself this is possible now.

                              So I borrowed a metal cut off saw 3350 mm (14 in) fitted with a "stone" blade I did some cuts. Worked like a charm !. ( but bloody dusty!) As you can see from the pic the buttressing is mortared in but the "brick veneer" is just stacked to see the effect. I like the rough effect from the mixed brick and the rough edges so for the moment I have broken the bricks in 1/2 with the brick bulster then split them with the saw. Works alright at the low levels but I will really have to think about the upper as it will end up needing? Triangular cuts or will I except the triangular gapes? Same again with the mortaring ... Will I mortar row by row like brickwork or will I spread the mortar like render and do section by section?
                              Any way the chimney will have to go up a couple of bricks higher perhaps?
                              Still in the planing stage but its all good.
                              A lot of work still to be done all of that paint will have to go with a wire brush on the angle grinder , then the surface roughened and keyed the dismond blade...well that's autum,winter, spring in SE Qld cool, dry, and perfect for the outdoors!....and pizza
