Total 160 fire brick
Arched vault 76 #1-a arch fire brick
Front entry arch 15 #1-a arch fire brick
Super 3000 refractory cement 50# $47.00
Noxcrete Castable 4 bags $114.00
Rock Wool - $14.00/bag $75.00
"Insblock 19" - 36 SF insulation between floor and slab $23.00
Diamond blade $33.00 when the blade stops cutting and starts just flaming, run it through a cement block a couple of times to dress the edge. Itll then be good for a few more cuts. Just keep doing that until you're done cutting. Don't try to cut all the way through a brick in one pass. Cut in increments of 1/4" to 1/2" cuts until you're trough the brick.
Total materials for the basic oven &1200.00
Additional expense will be determined by the outer wall treatment, which will be different for each oven, depending on style preferences of the builder/owner
Remember to leave dump slot for ashes if you decide you want to use it. I found it wasn't that important, as you don't need to clean out the ash very often. The high heat tends to reduce your burned wood to very fine ash.
Lay base brick and mark for outer wall placement.
Remove floor bricks and cement walls in. After first course of fire brick is down, lay floor back in on bed of sand or insulating board (Insblock 19)
Stand arch brick on end on plywood to scribe the arch and skew. If skew works right make of ½ fire brick cut 45° and lay into dry trial. If correct, build arch using 19 arch fire brick and 2 skew brick per course of arch (4 total)
Mark and saw arch and screw on 1/4 ply as form. Attach uprights to position form correctly.
Add secondary arch to front as interface to exterior.
You'll need an appropriate amount of insulation to cover the oven between the oven walls/ceiling and the outer walls. You can use Perlite, Vermiculite or Rock Wool (Mineral Wool). In Maine and New Hampshire I suggest Wallboard Supply, in Hermon, Maine
I found a really nice antique stove door for $35.00 at Bryant Stove & Music, in Thorndike, Maine
Remember to cut 1/3 of 6 arch brick on 1st 2 rows as flue exit.
Build chimney as the back wall goes up with arched roof. Attach the flue run to the chimney. (2 brick high on edge for sides and one a cross for ceiling of flue?) or castable with 4 bags (see photos of this on the other pages of this site)
