Firebricks are carefully levelled and nudged into place with a deadblow mallet. Scott Miller, Chris Affre and Christoph Altehoefer put the finishing touches on the hearth. The sidewalls are laid out dry and the mortar joints are marked. Recycled firebricks from an earlier Little Stream oven were used. New bricks could use thin fireclay mortar joints.
Side walls are in place, and back gable wall is up.
Scott Miller washes the bricks. Layout for arch template. Nail at bottom centre of arc and a string are used to establish the arc by trial and error until a whole number of bricks fits. Chris Affre cuts out the arch template with a Sawzall. A jigsaw would work well also.
