Chunk 'o steel

This chunk of 4140 came from Patrick Nowak at the 2006 SOFA. Patrick got it from his work, where it was a drop... the end waste piece of a large forging. In this picture, you can see a six inch ruler and the 1kg hammer for scale. It is 6" thick, 14" across, and 31" long, which puts it at about 750 pounds of tool steel.
