Metal is a magical material that can be stretched, compressed, bent, curved and twisted. The same piece can take on an entirely different shape depending on how it is formed. This workshop will explore developing patterns and forming processes for metal sheet.

Your previous knowlege of how to make blanking dies will give you the ability to quickly cut out duplicates of your pieces giving you the freedom to get lost in the design process and experiment with forming and assembly.

Working with your unique shapes will require making unique forming tools. Using wood, hard and thermal plastic and steel we will design tools that will give you consistent results. We will also work with ways to assemble multiple forms by soldering or using cold connections.

The goal will be to take an idea through the pattern development stage and explore multiple forming techniques for the resulting shape. You will make tools specifically for each forming process, resulting in finished pieces. Jayne will initially give each student a choice of shapes to work with as practice pieces to teach concepts and demonstrate the tools she created to develop each form.
