  • Assembly Order

    Plan solder sequence from highest to lowest melting point before cutting first piece.

  • Binding Jig

    Build plywood jig to hold shells aligned during hinge soldering.

  • Patience

    Hinged boxes rarely succeed on first attempt — budget scrap for practice hinges.

Safety Notes

  • Small parts become projectile hot — clear bench area.
  • Use fire-resistant surface for all soldering steps.
