I layed the face brick up to a point where I could clear the fireplace. I intend to surround the firebrick chimney with facebrick. I will have an insulation space between the two. My intentions are to pour 5 to 1 vermicrete in all voids between the the fire brick and facebrick. To do this I would have to transfer the weight of the facebrick over the dome side of the chimney to the outside walls. This is what I came up with:

This drawing is by no means true to scale but should help explain the basic concept. Gray areas in the drawing are 6" X 3 and 1/2" reinforced concrete lintels. The ends of each will also serve as corbels for concrete shelves.

I poured the two that you see in the forgeround wrong. They are available for free to a good home. Just pay shipping and handling
