Jim Campbell Hammer-In - 5/4/2013

Stephen Yusko (left) of Columbus, Ohio pierces a metal plate for a blacksmithing demonstration during the fifth annual Jim Campbell Hammer-In at the Touchstone Center for Crafts in Farmington, Saturday, May 4, 2013. The yearly event consists of a gathering of blacksmiths to get acquainted and compare projects and techniques in their craft. Jim Campbell (right) has been volunteering at the center's blacksmithing program for many years and helped make the program what it is today through his contributions.

Stephen Yusko heats a metal plate inside a furnace as he prepares to subject it to a technique known as "forge welding" in which two pieces of metal are heated entirely and then hammered together to create a textured surface.
