Decking

Decking support is made starting with scale 3"x6" mitered to 22.5 degrees and cut scale 6' long point to long point and glued with white glue. Cross supports are cut from 6"x6" (this is easier than ganging 3"x6"s) and glued in place with white glue. Lastly, attach a second ring of scale 3"x6" halfway out with white glue.
Decking is built from scale 1"x8" stock. First edge glue pieces to build up a scale 6' wide panel. Then miter this panel at 22.5 degrees so long edge is flush to the outside of ring. Then attach to the support ring with white glue. The result is a "parquet" look that is consistent with the prototype photographs.
