- Read the safety rules for metalwork listed in the Metalwork merit badge pamphlet. Describe to your counselor Discuss how to be safe while working with metal. Because this merit badge offers four options, show your counselor which additional safety rules apply to the discipline you choose and discuss them with your counselor. Discuss with your counselor the additional safety rules that apply to the metalwork option you choose for requirement 5.
- Define the terms native metal, malleable, metallurgy,
alloy, nonferrous, and ferrous. Then do Do
the following:
- Define the term native metal.
b. Define the term malleable.

- g. Describe how to work–harden a metal.
- h. Describe how to anneal a non-ferrous and a ferrous metal.
- Define the term native metal.
- Do the following:
- Work-harden a piece of 26- or 28-gauge sheet brass or sheet copper. Put a 45-degree bend in a small piece of 26- or 28-gauge sheet brass or sheet copper the metal, then heavily peen the area along the bend line to work-harden it. Note the amount of effort that is required to overcome the yield point in this unworked piece of metal.
- Work-harden another piece of the same sheet
brass or sheet copper. and then put a 45-degree bend in it. Note
the amount of effort that is required to overcome the yield point.
c. Soften the same bent, work hardened piece from requirement 3a by annealing it and then try to remove the 45–degree bend. Note the amount of effort that is required to overcome the yield point. - Make a temper color index from a flat piece
of steel. Using hand tools, make and temper a center punch of medium-carbon
or high-carbon steel.
d. Join two small pieces of scrap metal using a hammered rivet. Repeat the process using a pop rivet.
e. Using a flatlock seam, join two pieces of scrap metal together with either lead-free solder or silver solder.
f. Make a temper color index from a flat piece of steel. Using hand tools, make and temper a center punch of medium-carbon or high-carbon steel.
g. Using metal cans, practice using the basic metalworking tools and techniques by making at least two tasteful objects that require cutting, bending, and edging.
- Find out about three career opportunities in metalworking.
Pick one and find out the education, training, and experience required
for this profession. Discuss this with your counselor, and explain why
this profession might interest you.
Do ONE of the following:- Visit an experienced sheet metal mechanic, tinsmith, coppersmith, jeweler, founder or a blacksmith at his or her workshop.

explore metalworking occupations by conducting a Web search. With
your counselor’s help and guidance, find at least five metalworking–related
Web sites. Print a copy of the web pages and discuss them with your
counselor.
