Task · part of 3. Three bench exercises, and 3(a) and 3(b) are one piece of metal
3(a). Work-harden a piece of sheet brass or copper
Required Often forgotten
26- or 28-gauge, a 45-degree bend, then heavy peening along the bend line. Note the effort needed to overcome the yield point. KEEP THE PIECE: requirement 3(b) needs it.
Notes and warnings
Warning. KEEP THIS PIECE OF METAL. Requirement 3(b) anneals the very same piece and asks you to compare the effort needed before and after. A fresh piece proves nothing, and this is the only step on the badge where a physical object has to survive between requirements.
