We work and cast in the high school shop, or work with lead and pewter in the area outside the classroom. Bullets are cast outdoors, most often with an electric pot. A bench in the classroom has several vises for holding parts. Tools remain simple, in the realm of hand operated. The tools used most frequently are files, chisels, scrapers, and sandpaper.
Safety is taught before and during ongoing projects.
Goggles, ear protection, shooting glasses, and leather welding gloves are important pieces of equipment. Students police each other in this arena pretty well. They are proud to know the correct way of doing things. Use sharp, good quality tools and show the students tricks for keeping things in good condition. No really large investment is needed.
