sucker rod spark test (4130)


This is a spark test from a piece of sucker rod passed out at a CBA tool workshop. It was qualified as 4130, which seems plausible from the application (many sucker rods are made of 4130). Also, the head instructor spark tested, forge tested, and hardened and tempered and file tested it. Molybdenum arrows are visible, but maybe not to as great an extent as shown in BP0020.
