Answers: How do you build a mechanical vault door for an underground tunnel?

• Mechanical vault door construction
• Gear mechanism design
• Metal fabrication and welding
• Lathe and CNC plasma cutting

What it concludes

• The Wazer waterjet cutter produces sharper and better-defined teeth on custom gears than plasma or laser cutting, despite taking longer.
• Using a wooden template before cutting large sheet metal prevents costly material waste.
• A motorized gear mechanism with brass pins and spring-loaded contacts successfully operates the vault door's locking and lighting systems.
