Portable True Brick Ovens

The requirements of portable brick ovens are specific. They need to be structurally strong, contain enough mass for constant output of baked product yet within reasonable weight limits for common vehicles.
These photos are of  two portable real brick ovens, one 42" interior diameter and one 48" interior diameter.
Both ovens require V-8 vehicles for towing but both are on trailers with electric brakes.

My original portable oven (at left) used for the "Meet the Chefs event"  at the Northern New England Home and Garden Show along with green and stone benches I installed

More photos will follow as the 48" oven is finished with a veneer of brick and stone.
