Spinnaker pole bell, brace block and pole car
Three pieces of custom yacht hardware: a pole bell that lets spinnaker poles carry a mast down, a replacement brace block, and a pole car proposed for a sixty-footer.

Run the machine
A working model of a machine we designed and built, rebuilt from our own drawings and driven by the parameters that actually define it. Drag to orbit; move a slider and the geometry is recomputed.
These are demonstrations, not design records. Each is built from what we hold — drawings where drawings survive, photographs where they do not — and it is a preview of the article, not a drawing of it. Nothing here should be used to order, manufacture or check a part. For dimensions, ask.
