Just 9 more work days till the oven is finished and I thought i'd detail the end process here.
You really need to read the previous post first to have this one make sense. these steps will also be expanded on in coming posts with images.
day 1) cut the "drop" bricks to size, what i will be doing is cutting there edges so they fit properly on an angle and create a good seal. Create a small arch template, this is for the small 1/3rd bricks on the side. Fondue "drop" bricks into place with last of the front of oven bricks using the "L" metal to hold the bricks over the oven door. Cover the whole section in fondue to make a good seal.
day 2) Clean up the inside of the drop with angle grinder and remortar any holes. (see previous post of the dome clean-up)
day 3) Mortar/build chimney section including part that overlaps the "drop" . build the dome sides wall wooden borders that will hold the concrete/fondue mix that will hold the sides together and insulating and provide a nice even outside surface to render. Place the insulating wool and chicken wire over the dome and drop ready for the concrete/fondue mix ( I may be adding vermiculite in that mix as well.
day4/5) this will be a LONG day, fill the sides with concrete/fondue covering the wool UP TO when the dome stops being vertical and starts its arch section THEN sitch to a concrete/fondue/vermiculite and clay mix to cover the dome top. There are 2 reasons for this change in mix, the first is I want the sides to be SOLID and the weight of whatever i put on top will natutally push the dome sides OUT, the second it that heat rises so most of the heat and thus insulating should be at the top of the oven, thus the vermiculite and clay, the clay is simply because its good to use but also I have ample supply in the backyard so why not use it !!
This will seal the entire oven back to front up until the chimney begins, my chimney is a decorative OLD chipped brick so i want it to be seen.
day 6) remove the wood holding the concrete together and hope it all worked ! complete the top of the chimney with the flue going through the roof of the outdoor area ensuring the smoke escapes. hopefully my front pavers will arrive by then and i will create the front paver "level" so i can set them.
day 7) Lay the front pavers, I need to let them set so this will be an easy day, I will then build the front arch another day as I really need the pavers to be solid as a rock, but i have other small projects to do so no big deal.
day 8) build front arch, as i am doing a double brick side which will be very stable I shouldn't have a problem with the dome weight but it would be better to wait after building the vertical before doing the dome.
day 9 ) add extra vermicullite/clay mix to top of oven if I feel it needs it. by the time i get here i would have done some firerings of the oven and would have got it to a good temperature so it will depend on how hot the oven gets.
During this whole process I will also be creating the oven door and tools to use in the oven, more on that later.
