Master patterns and production tooling belonged to whoever paid the invoice. On the other hand, whatever was used to build the pattern, things like jigs, fixtures, molds, negatives, or plugs, was recycled in the shop, or was dis-guarded.
Stuff like that usually got thrown into the scrap barrel. The objects that are the focus of this story escaped that fate and ended up on a shelf in my garage. I think they have a story worth telling.
Patterns often required unique shapes that had to be “developed”. Development jobs involved a bit of thought into how to accurately create the shape. Some shapes are just plain “cool”, as well as being descriptive.
This is a picture story about one of those jobs that was nothing but a compilation of unique shapes.
