Navigational instruments

Some time ago at college I had the opportunity to do some metal work which to my surprise I really enjoyed. For this project we were looking at navigational instruments and we were asked to design and create our own navigational instrument using either aluminium, copper or brass.  After we covered the basics of how to work with metal and how to safely use the tools that we were given we were asked to experiment with as many different ways of working with metal as  we can. My final outcome of this project was a compass-necklace that I designed and made using copper..and one black button.
