Run a cable bench in your program.

Lesson plans, printable posters, a grading rubric, and a safety check you can hand to students. Built from the same content as our repair bench, so what they learn is what we do.

Safety check (student copy)

  • Iron stays in the stand when it is not in my hand.
  • I know the temperature and why (leaded vs lead-free).
  • Fume extraction or an open window, every time.
  • No mains cords, no batteries, no amp outputs on this bench.
  • I test with a meter before anything is plugged in.
