One thing led to another, and the projector balcony in this Nantucket "Home Performing Arts Center" ended up looking like a scallop shell from below. The radial joists penetrate the curved rim band and are wedged. When it came time to hang the entire thing from the arches above, we wanted something special. Randall and I ended up in the back room of a local machine supply store, sizing chains for the job. Even their lightest one would have carried the design load. We went by feel and look. This was such a fun mission that we celebrated by buying donuts for the entire shop and office. A great morning, in detailing timber and design/build construction. And in shopping.
