My husband Ollie decided to build an Electric discharge machining (EDM) machine a couple of months ago.
EDM machining is a process where a shape is obtained from a piece of metal by using sparks to remove material! If you have a shape that you wish to reproduce-you make a copper positive of the shape you wish to reproduce (hereafter called the electrode), and by passing a high voltage spark between the electrode and the process material (will become the finished part), erode the process material to exactly match the shape you want.
