2013 MHA Annual Meeting

Precast Geodesic Oven
with Marty Pearson

Precast geodesic oven

Precast pieces for a 36" geodesic oven.
There are two shapes, a hexagon and a pentagon.
The group on the left is hexagons cut in half, for the bottom course.
Note that the cut piece in front is dished in shape, and not flat.
The shape is identical to a soccer ball cut in half.
For more information on the dimensions of the molds, and geodesic ovens see the 2008 Workshop Report

After the 2008 workshop, Marty Pearson salvaged the molds and used them to cast these pieces.

Dry fit.

The geometry for the molds was copied from a project on the Forno Bravo forum. It was close, but not exact - notice the wedge
shaped joints. However, that is what mortar is for.

After the dry setup, the internal temporary support pieces were left in place, to act as a guide as well as provide temporatry support.
