Upright Pianos, Flags, Wet/Dry Vacuums, Medieval Axes

How It's Made – Season 24

Wooden cases, soundboards, strings, keys and intricate action mechanisms are assembled and regulated to create upright pianos. Fabric is printed or sewn into flags; motors, filters and collection tanks are combined in wet/dry vacuums; and forged steel axe heads are hardened, sharpened and mounted on wooden handles.
