Pneumatics
Pneumatics is a way of making things move using compressed air. In prop making, it's used to create moving parts in props, animatronics, and special effects. Think of it like using air pressure to make puppets move, doors open automatically, or create special effects like steam or fog. It's similar to hydraulics (which uses liquid), but pneumatics uses air instead. Prop makers use pneumatics because it's clean, safe, relatively simple to work with, and can create smooth, controlled movements. When you see a prop that moves by itself in a theater show or a movie set piece that has automated parts, there's a good chance pneumatics is involved.

Senior Level Questions
Q: Can you explain how you would design a pneumatic system for a large-scale moving prop?
Expected Answer: A senior prop maker should discuss safety considerations, planning the air supply, choosing appropriate components, and creating fail-safes. They should mention experience with similar projects and problem-solving approaches.
Q: How do you train junior prop makers in pneumatic system safety?
Expected Answer: Should demonstrate leadership experience and knowledge of safety protocols, including proper pressure handling, emergency shutoffs, and maintenance procedures. Should emphasize the importance of documentation and regular safety checks.
Mid Level Questions
Q: What maintenance procedures do you follow for pneumatic props?
Expected Answer: Should explain regular checking of air lines, cleaning procedures, leak testing, and preventive maintenance schedules. Should mention documentation and troubleshooting common issues.
Q: How do you calculate the air pressure needed for a specific prop movement?
Expected Answer: Should be able to explain basic calculations for determining appropriate air pressure, considering weight, movement speed, and safety margins. Should mention practical experience with different types of movements.
Junior Level Questions
Q: What are the basic components of a pneumatic system?
Expected Answer: Should identify basic parts like compressor, air lines, valves, and cylinders. Should demonstrate understanding of how these components work together to create movement.
Q: What safety measures do you take when working with pneumatic systems?
Expected Answer: Should mention basic safety protocols like pressure relief valves, emergency stops, proper equipment handling, and the importance of following safety guidelines.
