Here are some photographs we took as we built our oven, along with brief descriptions of each one. I will add some more details as time permits. Click on each thumb-nail to see the enlarged version of the picture. Our oven was built using plans from Ovencrafters.
Form
boards, re-bar and wire mesh set for pouring of slab.
Plywood
form to support oven slab has been put in place.
Vermiculite mixture has been poured and re-bar is in place for
pouring oven slab. Note plywood form in front which keeps space
open for ash drop.
Setting the firebricks on top of the oven slab.
Red bricks for oven walls are set and braced in preparation for
building the arched oven ceiling.
Building the arch. The most exciting and satisfying part of the
whole oven-building ordeal.
Oven has been covered with concrete, and block walls are up.
A close-up before the front walls were finished and the vermiculite
insulation was poured in.
This is looking down into the oven housing from the front. At
the center back are two plastic vents (one would probably have
been enough. The rough concrete is the 2" - 3" layer
covering the bricks of oven ceiling. The iron L-shaped rails running
from the front to the back were used to support a 3/4" plywood
roof. The underside of the plywood was lined with heavy-duty aluminum
foil. The roof is fastened down with hurricane straps and covered
with stucco. The only problem we had was a thin crack in the stucco
which formed in the back where the plywood met the concrete blocks.
We believe this happened because we did not use enough hurricane
straps which allowed for some flexing of the plywood.
The housing is almost finished. You can see the hurricane straps
sticking out from the tops of the walls. They were concreted in
place then bent over and screwed down into the plywood roof.
The chimney is finished, the base coat of stucco is on, and the
first fire is lit in the oven.
